    This family wouldn't even go down into this space, they had a whole downstairs that no one wanted to look at. Our team came in and installed silverglo insulation, a wall system and flooring. The family was so happy they finished the space and now they have a new bathroom they use daily!

    This homeowner had a beautiful finished basement but this last year the wall was softening and has a strange dark area. When our team came out to inspect they discovered that this was due to a large concentration of wet soil behind the basement wall on the exterior. Over time water began to work its way through the concrete wall and now the family risked damage to the finished walls of their home. Our team came in and placed not only a drain system to collect this water but also installed our patented Bright Wall panels to ensure the walls of the basement remained strong for the life of the house.

    Woody had sealed off this small area of his house and enclosed it to cover a wet and unsightly basement wall. After enough cracking and mold, he decided it needed to be handled. Having already used us to encapsulate his crawlspace, we were the first and only call this home owner made. We repaired the crack and installed our lovely Brightwall panels to finish the space and make it functional for the home owner.

    After

    This wonderfully finished basement had been a cozy lived in area of the home until just last year. After a heavy rain they noticed wet spots on their finished wall and coming in where the wall and the floor meet. A few more regular rain showers and this family was left with standing water and multiple leaks in their basement. This required them to tear apart their whole space due to water damage. Our team came in and installed a drainage system, crack repair and our patented Thermal Dry Wall system. This system ensures that no water or moisture will come in contact with the living space or building materials used to finish the basement walls.  Now that the space is free from water intrusion issues they can refinish the wall and never have to worry again.

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.
