Basement Sealants

Usage of interior sealants in basement waterproofing has always had its share of positives and negatives. While some people prefer the use of sealants, others detest them!

There have been debates regarding the effectiveness of interior sealants basically because it is less expensive and typically can be applied without hiring an outside contractor.

Additionally, with the usage of interior sealants, the total cost of basement waterproofing comes down substantially over other alternatives making this waterproofing method a favorite of the "DYI" homeowner.

So what is the truth? Are sealants effective?

The answer is; it depends.

Interior sealants are a poor choice if your basement has masonry construction. This is due to the substantially porous nature of the masonry blocks. Sealants are less effective with a porous material and need to form a "coat" over the intended area. You will need to explore other alternatives and not rely solely on the use of sealants.

However, interior sealants are one of the most effective choices to waterproof your basement if you have a poured concrete foundation.

Why are sealants more effective with poured foundations?

When you have a poured concrete foundation, you are not dealing with the same porous nature of masonry. Although concrete is not totally impervious, sealants are more effective with concrete and can form a waterproof bond to the surface.

Also, with a poured foundation, cracks and pipe outlets are the most common avenues for water to enter the basement. These areas are the easiest problems to locate and will benefit the most from the usage of sealants. To correct these issues, cracks and pipes are simply treated directly with a sealant. The sealant is normally an epoxy or urethane compound. The sealant in some cases is pressure injected into the openings and the cracks.

Since the sealant is injected under pressure, it cuts through the path of the seepage. As the sealant dries and hardens it blocks the seepage from reoccurring. These kind of sealants are known to last for a very long time, in some cases, even decades.

Your local hardware store will probably carry a number of sealant products for you to review. Ask to speak with someone familiar with your specific waterproofing issue and who can recommend a product and treatment method.

However, if you don't have time or prefer to have this work done for you, get bids from a local contractors specializing in basement sealant protection. Friends and neighbors are always happy to recommend a good contractor and share with you some "not so good" experiences as well.

As you speak to each contractor, make sure they provide you a good overview of sealant choices and job costs. Also, get everything in writing and if you decide to utilize a contractor, make certain you receive a signed document stating the terms and conditions of their waterproofing guarantee.
