What is Bentonite Injection, and How Can it Help My Leaky Basement?

What is our bentonite injection for exterior foundation walls? Bentonite as a material is simply a western clay, with the difference of having a 60 percent silica content. The large percentage of silica allows this clay to expand 18 to 20 times its volume when wet. When pumped under pressure into the ground, bentonite will seek the open capillaries of your settling backfill, fill them, and expand to seal them – preventing water from seeking that path into your basement.

Bentonite clay is the result of volcanic ash mixing with the same type of clay found in our own area. This clay is sold commercially under the brand name of Volclay® sodium bentonite. The contents are commonly seen on vitamin labels, are 100 percent natural, and are already reduced to its lowest state of composition. That means Volclay will not decompose into anything else over time. Volclay will remain just that – Volclay – once placed where it needs to be.

Our exclusive bentonite injection service has allowed our company to put a warranty on basement walls below grade for more than 30 years.

The process of bentonite injection has been around commercially for more than 80 years and was a prime method for sealing earthen dams and maintaining cofferdams for temporary water containment. For 50-plus years, few companies have effectively adapted this principle for residential use. What does this mean for the average homeowner? Well, those waterproofing companies who have mastered this process are able to provide a warranty for your basement wall. That means, if there are 35 companies competing for your business, there will only be one company that is able to provide a warranty on your basement wall. Basement Waterproofing, Inc. is one of those few companies.

    Who would think a product like this exists? For me, it’s great news because I’ve been dealing with basement flooding and leaking for years. I’ve had a couple different companies come in and help get the basement dried out and mold remediated, but nobody has ever really fixed the problem. Sounds like this might be a great option for me!
