Basement Waterproofing – Types of Approaches

 

Basement waterproofing is a science, and must always follow the basic guidelines of research & development.

 

Approach #1 – Waterproofing Sealants

Its common for NJ homeowners to find water in their basement, and misunderstand what is actually going on. They may also minimize the problem because they find it hard to accept the financial burden that comes along with properly waterproofing a basement.

We get a lot of phone calls from homeowners asking us if its ok to use a waterproofing sealant to plug holes in their foundation blocks. It is extremely important to understand, that even if a small amount of water is seeping through your blocks, this doesn’t mean a small fix will stop the problem. Hydrostatic water pressure is what leads to water seepage in the first place. Every cinder block in a foundation has 2 layers. The outside layer, and the inside layer. If you plug the inside layer of the blocks, you are doing nothing to address the real problem, which is the immense pressure pushing on the outside of the blocks.

So what commonly happens in these situations is the homeowner seals the inside of the blocks. Then a few weeks or months later, the pressure from the water erodes right through the seal. Or the seal can cause another section of the blocks to break away, making the leak even worse!

 

Approach #2 – Interior Drainage Systems

This type of approach is a lot more sensible. Although it is not true “waterproofing”, it is the technique that our company employs in 80% of situations. The goal of interior drainage systems is to manage the water flow into your basement or crawlspace. These systems operate in a way where they don’t actually stop water from coming into your house. What they do is redirect the water flow the second is passes the outside layer of your foundation walls.

This technique is effective because it solves the hydrostatic pressure problem. It keeps pressure off the outside of your foundation, and stops the corrosive effect of water persistently eroding away your bricks. However, this type of work must always be done by an experienced waterproofing company in NJ. There are people like plumbers, or friends you might have, who may understand the basic process. But there is a lot more to this process than installing pipes and a sump pump. So please, if a company has suggested this type of approach, do not attempt to do it yourself. You will wind up wasting a lot more money and risking much more significant damages in the future.

 

Approach #3 – Exterior Waterproofing

Exterior waterproofing is the only true form of waterproofing. However, most companies do not employ this approach due to the mere cost of it. A typical exterior job can run between $20,000-$50,000. While interior systems can run between $3,000-$20,000. With exterior waterproofing, all the dirt around a home is excavated. Then the outside of your foundation will be exposed and cleaned with special equipment. Once this is done, it will be resealed with tar, and preferably a second layer of rubber membrane.

However, even an exterior waterproofing fix does not guarantee you will never get water again. Water has a knack for finding its way back into a home. If it winds up coming through the floor a few years later, you will need an interior waterproofing system installed. This is why many companies prefer to start out with interior systems.

Please keep in mind that in this industry, more expensive does not mean higher quality. Systems will vary wildly between one waterproofing company to another. This is why you should take your time during the screening process. Ask as many questions as possible. Make sure the waterproofing inspector gives you specific answers. We have a lot of advice on our website regarding the most common mistakes that are made while waterproofing a basement. So please take the time to educate yourself, never rush to sign any contracts.
