Defining Waterproofing a Basement.

Sunday, January 25th, 2009

What are basement waterproofing systems and how do they work? Let’s take a look at the time and tested waterproofing of basement and how it works.

If you imagine how a basement is first built, when the house it is sited in was first conceived, then basically the following happens. A big hole in the ground is dug, the footer or foundations are laid, the walls of the basement are built and then the rest of the house follows.

From this list the most vital point is the top one – the vast crater dug in the earth

When basement walls are constructed there is an area outside the walls that must be filled. Loose backfill is what is used to fill this void. The problem here is that water looks for the path of least resistance, and you’ve just given it just that with a huge pile of loose backfill, no matter how well it’s been compacted.

This area is going to have water constantly seeping into it. The conventional way of waterproofing a basement provides some form of drainage pipe for this water to drain away, but the problem with this is that often these pipes get silted up. It’s natural enough, the water is bringing all sorts of suspension with it. The system can overload if the pipes get over-filled and then the pressure of the built up water would be concentrated on the outer basement walls. If there are crevices in the walls, water will push through even if the basement walls are waterproofed.

This kind of situation is persistent because the tubes that should drain the excess water eventually deteriorate.

A huge problem is that often there isn’t access to these pipes. Basement waterproofing is also applied to the external walls of the basement to try and keep the water out. This is also called a tanked system.

The drained cavity basement waterproofing system is a better system that works by getting rid of water pressure in the walls. To protect the property water is controlled, collected and then made to pass through hidden drainage channels which are either natural drainage or sump pumps.

To Waterproof a basement is reputedly a better system when installed internally, having easy access ports for removing any silt and can be applied to basements where traditional tanking or other methods have failed but with minimal disturbance to the original basement.

So to summarise, a good basement waterproofing system will:

- usually be a permanent or long-term solution
– stop both ways by which water can enter through the walls and up from the floor
– not disturb landscaping, decks, patios, driveways, etc
– usually be an approved waterproofing method for home loans
– often be substantially cheaper than other waterproofing methods

Choose a reputable basement waterproofer when protecting your home, remember it is economically foolish not to waterproof, because the increased value from waterproofing will definitely exceed the cost of the waterproofing.

In conclusion, you want a basement waterproofing system that will deliver:

- not disturb the exterior appearance of your home
– an approved method by home loan lenders
– more affordable than other methods
– stop water through the floor and walls
– a permanent or long term fix

You should look at waterproofing not as an expense but as an investment in the value of your home.

Waterproofing Your Basement

Sunday, November 2nd, 2008

Basement waterproofing services are everywhere these days. It seems like every week there is a new company fighting to get your business. This sector has become VERY competitive over the past few years. Here are some more tips to help get you started.

What is basement waterproofing and how does it work?

Let’s take a look at the time and tested waterproofing of basement and how it works.

In case you are curious to know how the basement is built, you will see that the idea was first conceived in the design and then the next steps follow. It starts with the digging of a big hole, then the footer or foundations are laid. After the base is done, the walls of the basement are built and then only the rest of the house is constructed.

That big hole in the ground, the first on the list above is important to note.

The construction of basement walls invariably leaves a void on the exterior which requires backfilling. This void gets filled with loose backfill. Well compacted or not, introducing a huge pile of loose backfill is going to cause problems.  Water will always flow in the path of least resistance.

Water will constantly ooze into this area. Typical ways of waterproofing a basement utilize water drainage pipes that often become silted. As the water comes it brings all sorts of suspension with it and that is to be expected as it is natural. When these pipes get filled the system overloads and a lot of water pressure gets applied to the outside walls of the basement. If there are crevices in the walls, water will push through even if the basement walls are waterproofed.

This type of problem doesn’t usually go away because the pipes that are supposed to take away the excess water gradually worsen over time.

Many times there is simply no access to these pipes which is a huge oversight. In an attempt to keep excess moisture out basement waterproofing also can be put onto the outer walls of the basement. This is also called a tanked system.

If you want to find out if you have water inside the concrete block of your walls simply tap a hole into the concrete block, near the floor, and see if you have water coming out of this block then you may want to consider drained cavity basement waterproofing. This system drains the water from your walls, much the same way you just did, by adding drain holes in the bottom blocks that allows those areas to drain into a type of interior french drain system. To move water away from your property; it first must be collected and sent through drainage channels to a sump pump or a natural drainage field.

Waterproofing a basement is when they are installed internally, have easy access ports for removing silt, and can be installed in basements where other methods have failed.

So to summarise, good basement waterproofing will:

  • not disturb landscaping, decks, patios, driveways, etc
  • usually be an approved waterproofing method for home loans
  • often be substantially cheaper than other waterproofing methods
  • usually be a permanent or long-term solution
  • stop both ways by which water can enter through the walls and up from the floor

Choose a reputable basement waterproofer when protecting your home, remember it is economically foolish not to waterproof, because the increased value from waterproofing will definitely exceed the cost of the waterproofing.

In conclusion, you want a basement waterproofing system that will deliver:

  • an approved method by home loan lenders
  • not disturb the exterior appearance of your home
  • more affordable than other methods
  • stop water through the floor and walls
  • a permanent or long term fix

You should look at waterproofing not as an expense but as an investment in the value of your home.

Use these tips to make dealing with basement waterproofing a lot easier. If you follow the basics you will eliminate your problem for a long time.

Methods for Basement Floor Waterproofing

Tuesday, October 21st, 2008

If basement floor waterproofing wasn’t overlooked on such a regular basis, then there wouldn’t be as many problems with seepage and flooding when it was finished. Basements are often thought of as just places for storage that have concrete floors and walls where you can store old toys, tools and other stuff. Now, people realize the potential of this space for something much more such as extra living space, family rooms and bedrooms.

Many homeowners go years without a water problem and then develop one due to the existing sub-floor and sub-surface drains clogging with mud.

The soil will become too saturated if water from the roof is not directed away from the foundation. As the home stabilizes, wall fissures appeared, exterior paintings decayed and the drains filled with sand or silt. A leakage in the basement might result from all these problems. Flowing ground water enters through cracks or other openings in the foundation; moisture in saturated soil enters through solid masonry as well as through cracks and other openings because of the natural pressure the soil exerts against the foundation. The level of pressure is positively correlated with the height of the water level. As water pressure increases, water begins to seep into cracks in the concrete walls and floors. The result is a flooded crawlspace or basement.

Pressure relief systems are a good way to prevent hydrostatic water from entering your home. Whenever there happens to be a power outage due to a rainstorm, it is very likely that the primary pumps will not work, and that may cause somewhat of an inconvenience. Over time this pressure increases until the moisture is literally pushed through the floor or wall (often called bleeding). Usually you’ll find seepage in corners or in joints where the wall meets the floor.

If water come from an isolated area and is installed a pump below the floor level will lower the water and the underground pressure However, concrete is porous and allows water vapor to pass through. Because of moisture it feels even more cold, and rots carpet and other floor coverings. Even the mold starts to grow and basement smells musty.

Using high quality sealants easily found in the marketplace is a good remedy. It is often possible to paint them with either the roller or spray method.

Here are some examples of what a regular basement floor waterproofing project might entail:

- preparing the floor by removing crumbly or loose material.
– Care has to be taken to see that the floor of the basement is absolutely dry,and for this one may need to hire large fans or heaters.
– making sure wall/floor junctions are sealed.
– Any cracks or joints noticed will need to be filled.
– priming the floor if the product requires use of a primer.
Spread two or three coats which is just right top-coating of the final product.

A high quality product will result in basement floor waterproofing that can last for years and years. There are sealants on the market such as PermaFlex which offer complete, permanent basement floor waterproofing. This is arguably the only waterproofing system that is suitable for indoor use that will result in the complete sealing of a basement floor, no matter what sort of state it might be in. And it is considerably cheaper than other type of work as it does not involve pipes or pumps!

If you’re looking for information on Waterproofing Basement Walls, this has it all.

You should always make sure to waterproof your basement walls when you are finishing it. Moisture entering through the walls of the basement  is the main reason that area of your house is more damp than the rest of the house. The most common reasons for water build-up problems in basements are caused usually by cracks, leaking windows and pipe condensation. You will run into all kinds of issues if you allow too much water retention or allow it to stay for too long.

Basement Wall Options

There are numerous ways of waterproofing basement walls and these include:

- French Drains
– Hollow Baseboard Molding
– Sump Pumps
– Waterproofing
– Damp Proofing

French Drains

You have many choices when it comes to waterproofing basement walls, however to get your best results you first need to figure out exactly how and where your water is coming from, be it through the walls from freeze thaw cycles or heavy rains and run off, or is it coming from an underground spring, or do you simply have a damp or humid basement?

French Drains

An exterior system running the perimeter or partial perimeter of your house for heavy rain run off drainage, or an interior system if water is coming into your basement through the floors or cove between the floor and the wall. An excavation was made inside the drenched basement floor. A perforated plastic drain tile pipe is installed and surrounded by gravel. Some wet basement waterproofing and repair contractors re-cement the floor over the French drain system leaving a 1 inch to 2 inch gap in the floor along the walls to allow the web wall seepage to drain below the floor into the French drain system. A French drain usually connects to a sump pump.

Hollow Baseboard Molding and Cove Systems

What might be the possible use of the Hollow Baseboard Molding? Is it good enough to adhere or joint for epoxy use? The hollow molding collects wet wall seepage and water rising at the cove area. Usually connected to a sump pump.

Sump Pumps

One item you can include when waterproofing your basement walls is a sump pump that can be installed below the basement floor. In order to collect underground water one case install a device known as a sump pump. This should solve your underground water problems! A good way of draining excess water from a basement floor or from any underground drainage pipes that you might have is to utilise a sump pump.

Wall Sealers

There are many types and varieties of basement wall sealers on the market to choose from depending on whether you want to brush or roll the sealant product onto your wall, or you may choose to install a panel wall system to seal your walls.

The fact is that even with a good drainage system there is no surety of the basement walls remaining dry. Lets look at damp proofing and waterproofing as these are the cheapest and easiest methods of stopping moisture getting into your basement through the walls.

Damp proofing means what?

You may be asking yourself what is involved in damp proofing your basement and the best example I can give of damp proofing would be to think of a castle with a moat and think about how to keep the water away from this castle; first you build the permiable palette layer where you want the castle floor, then you would place a solid layer over that, then you would leave a vent space and lay your foundation; as for your walls, you would build your walls, then do your solid layer and then your permiable layer, and now you have damp proofed your castle.

Damp proofing products are typically a tar based material in a solvent base.  Application is inexpensive but efficiency is limited since they are manufactured to retard and not to prevent moisture penetration.  The biggest problem is that, because this material becomes brittle, hairline cracks will appear as the foundation settles. Since the tar based coating does not stretch to cover these cracks, water will seep into the basement.

What is Waterproofing?

The water proofing products are such that they stop water penetrate into wet places as well. Because hydrstatic pressure in the soil after heavy rain or spring starts thawing.  Advanced Waterproofing Technologies provides supieor waterproofing protection as the products contain rubber and it allows flexibility when it dries.  How you will stretch the foundation to settle the flexibility of waterproofing

Applying

Clearly waterproofing is a better option and since there is not a huge price difference between that and damp proofing, it seems a more sensible long term  choice, especially when it often has a 25 to 30-year guarantee.

In the earlier days builders often did not consider waterproofing the basement walls as important. So now you can fix that with a product anyone can use. Even if you are not a professional you will find that our products are easily applied and not harmful.

These are available in 5 gallon pails or 55 gallon drums, as an example, and are ready for use without heat or any specialized equipment, if you can use a brush or a roller, you can use these.  You can even use a commercial airless sprayer which can be rented by the day.  Two people using rollers to waterproof a basement of about 1,000 square feet can accomplish the task easily in about two to three hours.  So get started and begin to enjoy your basement space without the dampness.

Waterproofing A Basement

Although it seems rather easy to waterproof a basement, there are many things that you must consider first. In fact, many of the things that you’ll read about here are not discussed often. Before you buy you start, consider the following tips

What is basement waterproofing and how does it work? Let’s take a look at the time and tested waterproofing of basement and how it works.

The construction of basement walls invariably leaves a void on the exterior which requires backfilling. Loose backfill is used to fill in the gap. The problem here is that water looks for the path of least resistance, and you’ve just given it just that with a huge pile of loose backfill, no matter how well it’s been compacted.

It’s natural enough, the water is bringing all sorts of suspension with it. Allowing these pipes to fill up, can result in an overload of the system, which can be catastrophic to the basement’s outside walls. So while the walls of the basement may be waterproofed in some way, water, as you probably already know, will usually find a way through the tiniest of gaps.

This type of problem doesn’t usually go away because the pipes that are supposed to take away the excess water gradually worsen over time.

As you can see, the problem of basement waterproofing is not uncommon and there are steps that can be taken to make your life a lost easier when dealing with it.

Waterproofing Your Basement can be Done by DIY.

Tuesday, October 7th, 2008

Most homeowners will often have water leaks in their basements, if they have one, so it is almost a guarantee that they will look to purchase DIY basement waterproofing products and gather information on how to best resolve their leaks.

The first thing that we have to see is the cause of basement water seepage and flooding. Serious basement problems due to excess moisture many times cause numerous problems to the basement structurally, as well as limit space, and ruin and or destroy furniture and furnishings.

A large hole is dug in the ground to install a basement. Once the walls and floor of the basement are built, the remainder of the hole is filled in with effectively, loose soil, even if it’s compacted afterwards. The loose soil around the basement provides the least resistance to water and it will use this path to seep into that area. The end result of this is likely to be that you will find that there is an accumulation of water either surrounding or even underlying your basement.

This causes water to weigh down, and to exert pressure upon the floor, and upon the basement walls. This often attacks the outside membrane or protective coating, and/or water finds its way through tiny cracks or larger structural cracks. This sometimes happens even with systems that are designed to remove water away from the building because pipes get blocked with silt or heavy rainfalls overload the system.

This is when many people decide to try do it yourself basement waterproofing in an attempt to avoid the expense of having the basement competely dug up and re-done. Frequently used method is to handle the interior rather than the exterior, by utilizing materials like sealants on the inner walls and ground.

A typical project might involve:

the walls are prepared by removing all loose or crumbled material.
– remove any previous repair material or foreign material.
Heaters and large fans can be used to ensure that your basement is as dry as it can be.
Use a primer coat on the floors and walls if the product requires this to be done.
– patch any particularly noticeable flaws, gaps, seams or joints.
– wall/floor junctions may require a 1″ bead of sealant.
final products which using 2 or 3 coats are enough

That is about all If the product is a good one you will have a sealed basement that should last for a number of years. PermaFlex is a top sealant, and along with other complete sealants, they offer a permanent indoor basement waterproofing system. This indoor waterproofing system claims to permanently stop basement leaks and can be applied by brush, roller, or spray system.

A damp basement is a general problem for homeowners which could turn out to be very expensive if done by an outside repairer which could cost you thousands of dollars, so if you’re thinking of how to stretch your budget, you might try do it yourself basement waterproofing

Defining Waterproofing a Basement.

Saturday, October 4th, 2008

The basement waterproofing systems and their working. To answer that question, let’s first look at historically conventional basement waterproofing and how it is supposed to work.

If you can see a home being built the contractor first surveys the lot using the blueprints for the home to be built; then he sights out the lot to find out the best place to start digging and grading the property, then he lays the footer or foundation and begins building the basement walls, lastly the balance of the home follows.

The important point to note is the first one in the list above – that big hole in the ground.

When the walls of the basement are built, there is always a gap left outside the walls which needs to be filled. This void gets filled with loose backfill. The problem here is that water looks for the path of least resistance, and you’ve just given it just that with a huge pile of loose backfill, no matter how well it’s been compacted.

Water will continuously seep into this area. The conventional way of waterproofing a basement provides some form of drainage pipe for this water to drain away, but the problem with this is that often these pipes get silted up. It’s natural enough, the water is bringing all sorts of suspension with it. When these pipes get filled the system overloads and a lot of water pressure gets applied to the outside walls of the basement. So while the walls of the basement may be waterproofed in some way, water, as you probably already know, will usually find a way through the tiniest of gaps.

This type of problem doesn’t usually go away because the pipes that are supposed to take away the excess water gradually worsen over time.

In conclusion, you want a basement waterproofing system that will deliver:

- a permanent or long term fix

– not disturb the exterior appearance of your home
– an approved method by home loan lenders
– more affordable than other methods,

While you are getting the house made you need to realize that waterproofing is more of an investment in the value of your house rather then an expense.

Basement Waterproofing Materials and Uses

Saturday, October 4th, 2008

There can be some big differences in the basement waterproofing materials and the way they’re used. The general public may be able to purchase some, while other will only be for professionals. Let’s assess the situation and see how we can apply it to your home.

First of all though, you need to be aware that the area you live in also affects the amount of water that’s likely to be around. So take that into consideration as this will also influence the type of materials you can use.

The first type of basement waterproofing materials that most people seem to be looking for are simple sealants. In other words, they have a basement that has already had some form of waterproofing applied to it and are looking to patch small damp areas up. It is easy to find a sealant that can be used to treat the concrete once it has been poured, or indeed the mortar that is found in block walls. One type of sealant which is recommended for this is RadonSeal.

You have to coat all of the basement walls and the floor with sealant or else the water will still seep in around the edges of the treated area. The product has a 20-year limited guarantee. The only issue to be aware of here is that the sealant, (not just this one, but all sealants), will only prevent water seepage on the inside skin of the basement. In other words, there could be lots of water pressing against and through whatever materials your cellar walls are made of.

If you have cracks in the wall, you may need to consider other options. Plaster wall can be can be repaired by replacing the plaster coating. Throw away loose material and refill

Stitching materials can be used as an alternative option. These metal staples are stapled across the cracks to prevent or limit further movement. Any type of cement that is not prone to shrinkage can then be used to fill up any cracks.

More serious cracks in the walls or the floor of the basement can be filled with Gunite, a form of concrete that is sprayed on. You’ll need special spraying equipment to do this which you can hire. The resulting spray will fill cracks and leave a smooth finish, but you need to get the mixture ratio right. But it is still a good choice, because it adhere to most surfaces.

Finally, it needs to be said that basement waterproofing materials are not the ultimate solution. You should also be looking at making sure there is as little water getting into the ground around the basement as possible.

So also consider:

- be sure your rain gutters are in good condition.
– the soil is graded so that it slopes away from the foundation of the house
– removing flower beds, bushes and trees from around the foundations and seed with grass.
– repairing crevices in your driveway
– there can be arrangement for surface water to be taken away from the house by installing curtain drains
– you should install dry wells for rainwater downspouts no more than 10 feet from the interior of the property
– installing sump pumps.
– utilizing inside channels to gather water oozing through the basement walls and course it to a floor pipe
