The causes of a wet basement and what to look out for

Did you know you can have water issues in your basement without heavy rains or obvious standing water? It's easy enough to see water coming through a crack in your floor or basement wall, but what's the real cause of your basement water problem?

The Clay Bowl Effect

Excavated soil that's replaced around a completed foundation isn't as dense and tightly packed as undisturbed soil farther away. As a result, water collects in the soil immediately surrounding the house, putting pressure on foundation walls and causing cracks.

Hydrostatic Pressure

The weight of the water in the soil around the foundation exerts pressure, forcing the water through cracks, gaps, holes, and around windows leading into the basement.

Additional contributing factors may include poor surface water drainage, clogged French drains, broken sump pumps, and high water tables. Also, most homes that are more than a few years old have a waterproofing system that has degraded or been compromised to some degree. The combination of significant water pressure and suboptimal waterproofing systems often leads to wet basements.

Don't wait until your basement floods - look out for these signs:

Musty smell
Water seepage where walls meet floors
Standing water or wet areas
Damp or discolored walls
Peeling, bubbling or cracking paint or wallpaper

How we solve your basement waterproofing problems

A home with a wet basement can be much more difficult to sell. In fact, a wet basement is one of the most serious "red flags" that deters buyers. The good news: we offer waterproofing products and services to help solve your basement problems fast. Our solutions include:

Interior basement waterproofing

Our team will remove a portion of the concrete slab immediately next to the affected foundation walls. Then we'll dig an interior trench in the treatment area. Next, we'll install a subfloor drainage system.

This will evacuate water from below your basement walls and floors and move it away from your home through sloped, perforated piping connected to a sump pump or redirected to your home's exterior.

Exterior basement waterproofing

Our team will excavate a trench around your foundation and clean the foundation wall thoroughly. Next, we'll repair or replace damaged cement parging and seal cracks, seams, holes, imperfections and subgrade pipes. Then we'll apply liquid rubberized sealant to subgrade walls and install drain board paneling on treated walls. Lastly, we'll install a drainage system that moves water away from your home through sloped, perforated piping connected to a sump pump or redirected to your home's exterior so water can't penetrate your home's foundation walls.

Our system comes with a lifetime written warranty that's transferable to the next owner, so not only does our system restore value to your house, but it also gives homeowners and buyers confidence that their home is protected.
