Your Foundation’s Exterior Waterproofing

August 19, 2016 9:24 pm Published by Jane Azzinaro

How much do you know about the existing waterproofing on your foundation? Depending on the age of your home you may not have any exterior waterproofing at all.

Builders are required to coat your foundation in parging and tar, depending on the type of foundation, as a water repellant. This is normally guaranteed for the first year of your home’s existence. After that, it is your problem if the waterproofing begins to degrade and let water into your foundation.

Parge is applied in two coats to prevent cracking, and then the tar is added. The shelf life of this product is only seven years. How long do you think it will last underground with the elements? Now a days, the tar is strayed onto the foundation. To get it to run through the sprayer, it has to be thinned. This makes it wear off of your home sooner. How often have you replaced the tar on your foundation walls?

If you already have water entering your foundation walls, exterior excavation may be a solution for you. Excavation has its pros and cons. It can be costly and disruptive, but it can also solve your water problems. Contact Mid-Atlantic Waterproofing today to discuss the best course of action for your home.
