GSI Foundations = Interior Waterproofing Experts

Interior basement waterproofing is by far the most common type of basement waterproofing that GSI foundations performs for our clients. We provide the highest quality workmanship and competitive pricing. Interior waterproofing involves the installation of drain tile and drainage board; which allows any water that might accumulate in your basement to flow through to a crock where it is collected and then efficiently pumped out of your home.

Expert Interior Basement Waterproofing

Our drain tile installations are perhaps the best and most cost-effective way to capture rising groundwater (particularly important if you live near bodies of water, lakes, ponds, streams, rivers) and prevent it from seeping onto your basement floor.

At GSI, our highly-trained professional team takes great care in drain tile installation, and works hard to provide as little disruption as possible. We can work around your furnace or hot water heater – or any other structure in the basement that would be difficult or impractical to move. This flexibility will save you time and money, while getting the job done.

Once installed, our interior waterproofing system runs efficiently to help keep your basement dry and to prevent mold and mildew from growing.

The expert team at GSI Foundations can professionally waterproof your basement through interior waterproofing and drain tile installation.
