Foundation Waterproofing


Foundation Waterproofing Prevents Mold, Allergies, and Air Quality Issues

Foundation Waterproofing: What To Do & Why?

Mold can grow almost anywhere there is water damage, high humidity, or dampness. Mold spores take about 48 hours to form in a damp indoor space. From the crawl space, they travel up through the floorboards and into the home. Not only can this infect the wood floors and walls, but mold spores can also cause allergies, airway infections, asthma, and other breathing and health problems, particularly in children.

In order to stop mold from growing, you must first prevent your foundation from flooding.

There are two important factors that contribute to foundation and crawl space leaking: the clay bowl effect, and hydrostatic pressure. It takes a waterproofing specialist to prevent these forces from destroying your home. We specialize in stopping water at the point where it enters the structure.


Here at Weinstein Construction, our approach to solving water problems of all types ensures that your foundation stays dry permanently. Our waterproofing crews are experienced, well-trained professionals who work in basements and crawl spaces every day. They’ve seen it all, and they know just what needs to be done to keep your foundation or crawl space dry all the time!

One of the best things about having us waterproof your foundation is that we do it all! We apply a special waterproofing membrane on the concrete foundation walls, but if there’s other waterproofing ideas that need to be addressed, our crews are highly trained to install all of our wet crawl space and foundation flooding solutions, including sump pumps, french drains, perimeter drainage systems, dehumidifiers, and crawl space encapsulation.

Most foundation waterproofing jobs take less than two days and your foundation can be used immediately after. You’ll be surprised by the skill, speed, and flexibility of our team of waterproofing professionals. They’re the best at what they do; Flooding foundations, leaking wall cracks, and moldy crawl spaces are the kinds of challenges they specialize in.

  • Job Completion And Followup

We like to call back a few days after the work is completed to make sure that everything was complete the way it was proposed. We’ll also call back during the rain seasons to ensure the system is holding up against the rain. If needed, we’re always happy to schedule a service repair on any system that we install.

By being able to address any feedback or issues, we are also building a relationship in case you’d like to upgrade your system with us in the future. Our goal is to be here for you when you need us!
