    This customer had a finished basement that was used for kids living space, but without the proper waterproofing system in place they started to get water seepage and leaks down in the kids’ bedrooms! destroying their stuff and leaving it an unsafe place to dwell in. Our team came out and put in a full Watergaurd system and put in our Thermaldry Wall system which will help reflect heat and make the room much warmer for the kids as well. This basement is now warm and dry!

    This customer was wanting a quick solution to the water coming into the basement so they could finish it. Not only did we solve the water issue by installing our Waterguard system in just two days but we also helped get them on the right track to finishing it by putting in our Thermaldry wall system and our Thermaldry floor matting. These products help to waterproof and insulate the walls and floor, making the basement perfectly prepped for finishing.

    Note: the floor matting is not pictured in the after photo since it was done at a later time.

    Anyone know what the most important part of a waterproofing system is? It's the pipes! Without them what would be taking the water out and directing it somewhere new? That seems to be a reason we come out to homes a lot. Failed drain pipes. The pipes need to be taken care of and a lot of the older ones will clog and rust causing a mess. In this before picture you can see how rusted up that discharge line is. We replaced it with some of our own material that will not rust and has a tough seal preventing leaks.

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.
