    Before

    After

    The customer called us and inquired about our waterproofing systems. Their basement was getting water through the foundation walls and floors, and wanted a permanent solution to the problem. Eric Greenberg, one of our system design specialists, did a thorough inspection. He found signs of water damage along the walls and floors. He was able to create a system that would keep the basement dry all the time. 

    Our installation team first removed the mold from the area. Then we installed our patented WaterGuard piping system around the full perimeter of the basement. Next, we installed CleanSpace on the walls to create a vapor barrier between the cold foundation walls and the basement. We also installed the SuperSump pump system and ran a discharge line out and away from the house. The end result is a dry and healthier basement.

Professional, Certified Waterproofers in Long Island

Basement water problems are as old as the structures themselves. Water will leak into a basement through any opening it can, including your walls, floors, and the joints between them. Water can even pass through the concrete itself -- which is one reason why basements are notoriously damp, humid spaces.

Other companies might try to sell you on inferior basement waterproofing solutions. Our products have been developed, patented, and perfected by Basement Systems, Inc. -- the world's largest network of basement waterproofers. Meet with one of our basement experts, and we'll show you how we can customize your waterproofing solution to keep the basement dry all the time!

 

Negative-side Sealant

This involves "painting" the basement walls and floors with a waterproof coating of cement that's meant to seal out the moisture.

It applies directly to the concrete's surface with a brush or roller and is often applied when a homeowner is preparing for basement finishing.

Exterior Excavation

This involves digging out the entire perimeter of the basement, installing a new drain, and possibly adding a waterproof coating on the walls.

This type of installation has been used for many decades—a drain of this type is generally installed when the home is built.

Interior Baseboard System

Installs on top of the basement floor with a drain that runs along the basement walls. Collects water and sends it to a sump pump system.

No jackhammering is required, and the installation is safe for a monolithic basement floor.

Interior Subfloor Drain

Installs underneath the basement floor, with a drain that runs along the basement walls. Collects water and sends it to a sump pump system.

The system is easy to service, and it can collect water leaking from the walls or windows as well.
