Concrete Foundation Waterproofing in Philadelphia

Basement Waterproofing

Concrete is porous — not waterproof. We drain, treat, and seal foundations to keep basements dry and protect the structure above them.

Foundation problems can be the bane of any building owner’s existence. Other than a fire, they’re one of the worst things that can happen to a structure — and one of the biggest sources of foundation problems is water damage.

The foundation is literally the support for your entire building. Water is the most damaging element it faces, and it can cause a foundation to sink — which warps and damages everything above it. All damage should be taken seriously and repaired as quickly as possible.

Keep the area under your building clean and dry

Keeping the foundation dry is one of the most important things you can do to maintain and protect a building’s integrity. Beyond possible structural damage, water getting into basements and crawl spaces creates a perfect breeding ground for mold — making the space unpleasant and potentially unhealthy.

Concrete is porous — not waterproof

Concrete is the most commonly used foundation material, and it isn’t waterproof. Undamaged, new concrete will typically keep liquid water out, but water vapor passes through it with far less trouble — and causes problems all the same.

The best way to keep a building water-safe is to keep water drained away from the foundation. Drains that move water away from the base of the foundation are the first step in successful waterproofing. Second is a wall treatment that prevents moisture from moving through the walls, allowing water to run down into those drains instead. Third is ground surface treatment.

Waterproofing and sealing don’t just prevent damage to your property and belongings — they extend the life of the foundation itself. Many membranes and technologies are available for both above- and below-grade applications, and we’ll work with you to choose the best option for your concrete surfaces.
