Before and After
  • Baltimore Basement Waterproofing
    Before
    Baltimore Basement Waterproofing
    After

    This basement was getting wet during storms which made the drywall and carpet moldy. Drywall and carpet are made of organic materials so they easily get destroyed by water and mold damage.  The smell was noticeable and something had to be done.  

    Basement Systems USA, Inc. went in and first removed the carpet and the bottom of the moldy drywall and did some mold remediation.  The next step was to install the WaterGuard drainage system around the perimeter so that the basement would no longer leak.  The WaterGuard was connected to one of our SuperSump Systems which include a battery back-up pump so that the water can be pumped out even during power failures.  

    Once the basement is mold free and no longer in danger from water seepage, we could start putting things back together. But we would never use organic materials like drywall or carpet to repair the basement.  A special waterproof and inorganic wallboard called EverlastWall was used to make the basement look beautiful again.  EverlastWall is made of nonorganic material and is guaranteed for 50 years against water and mold damage.  We also used a special waterproof wood look flooring so that there would be no danger of water damage. 

    The result is easy to see. The basement is not only dry and looks amazing, it has been repaired with the right building materials so that the is no chance of water or mold damage in the future. Another job done right.

    This old, cold, and leaking window needed to be replaced with a new high efficient vynel window.  We also installed a WellDuct window well drain in the window well outside.  This drian is connected into the interior Waterguard systems to prevent window well flooding.  We also wanted to prevent vapour transmision, so the ThermalWall vapor barrier was installed. Thermal Wall also reflects up to 97% of the heat back into the basement.

    Before
    Waterproofing System and  Wall Restoration in Aberdeen, MD
    After

    This job required that we remove the bottom of the moldy drywall so that a waterproofing system could be installed.  We also installed a TripleSafe sump system that can pump over 6000 gallons of water and has a battery back-up pumping system.  We never use drywall to restore the wall because it is too vulnerable to mold and water damage.  Basement Systems only uses in-organic TBF EverLast wall that comes with a 50 year guarantee against water or mold damage.

That is how he found Basement Systems USA, and after getting to know the products and solutions we offer, he was 100% confident that this was the company for the job.

Affordable, Certified Waterproofers for greater Baltimore, Philadelphia, West Chester, and Lancaster

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 waterproofing contractors.

Whether you live in Philadelphia, Baltimore, Ellicott City, Wilmington, Upper Darby, Parkville or Lancaster, our basement experts will show you how we can customize your waterproofing solution to keep the basement dry all the time!

Exterior Excavation

Heavy equipment is brought in to dig out the entire perimeter of the basement. New drain lines are installed, and sometimes a waterproof coating is applied to foundation walls. This waterproofing strategy is expensive and often damages lawn and garden areas. Exterior drains are prone to clogging with silt and roots over time.

Interior Subfloor Drain

This drain line is installed underneath the basement floor, just inside the foundation walls. The hidden drainage system brings water to a sump pit, where a sump pump automatically pumps it outside. Also known as a French Drain, this system is not prone to clogging; it’s reliable and easy to service.

Interior Baseboard System

A hollow plastic baseboard is installed along the base of basement walls to form a drainage channel that directs water to a sump pump system. A baseboard-type drainage system is sometimes recommended when the basement slab is too thin to accommodate a French Drain.

Negative-side Sealant

This waterproofing technique involves "painting" basement walls and floors with a waterproof, cement-based coating that's supposed to seal out moisture. Even when applied correctly, this thin membrane usually fails in response to prolonged hydrostatic pressure from outside the foundation.
