Basement Waterproofing Photo Album: Repairing Leaky Cracks in Foundation Walls
This home in Perryville, MO. had several large, leaky cracks in the foundation walls in the basement. These cracks had become problematic over time, as they continued to leak and crack despite attempts to repair them.
This is a common problem in this region, as soil conditions in the Midwest can cause sustantial amounts of pressure and wall movement. This pressure from the soil can cause the walls to shift slightly, which will often re-crack repairs that were made to the wall. That's because these repairs are often rigid and inflexible, so they will break down over time with the pressures of the wall and soil (and water.)
To properly fix these cracks, Dave P. from Woods Basement Systems installed a comprehensive waterproofing system that would block leaks, patch cracks and redirect water from around the basement back outside. The first step was to install a drainage system that would act as a sort of highway for any water that would otherwise leak inside to be directed to the sump pump. This drainage system included WaterGuard™ which would collect water from below the floor before it could leak into the basement, as well as collect water from the walls before it could pool up on the floor. Where WaterGuard™ wasn't appropriate, a tube was installed beneath the floor that would allow water to be transported to the rest of the drainage system so it could also be pumped out of the home.
Next, the cracks were covered. Dave P. used FlexiSpan™, a tough but flexible cover that can permanently block leaks. It works by sealing the crack and adding a channel behind the surface of the wall that allows any water that builds up around that crack to drain down behind FlexiSpan's™ surface. Water drains down into the WaterGuard™ system or other drainage system instead of building up and causing enough pressure to re-damage the concrete or create new leaks or cracks. All the while, the surface of FlexiSpan™ will remain dry and crack-free.
These cracks won't bother the homeowners anymore now that they have been permanently fixed with the help of WaterGuard™ and FlexiSpan™.
Multiple FlexiSpan™ Repairs
These cracks have been covered with FlexiSpan™, which will block any leaks and permanently cover the cracks.
Adding a Seal
This crack is now sealed so that water doesn't leak past the chanel that was created for it and into the basement.
Adding a Chanel for Leaks
This large crack was frequently leaking water despite previous repairs. When Woods Basement Systems came to fix the problem they added a chanel behind the surface of the wall for water to funnel down and into the perimeter drainage system rather than leak into the basement. This chanel is then covered with a seal and a flexible yet durable outer layer.
FlexiSpan™ into WaterGuard™
This formerly leaking crack is now covered with FlexiSpan™ and any water that would have leaked through it is directed down into WaterGuard™ to be pumped away from the home.
FlexiSpan™ into Drainage System
It would be impractical to connect this entire wall with the WaterGuard™ system when only this crack experienced leaks. That's why the repaired crack will chanel water into a custom drainage system that can connect with the WaterGuard™ system elsewhere.
Crack Repaired Behind Sump Pump
This wall crack behind the sump pump was fixed with FlexiSpan™. The water that would have otherwise leaked through it is instead drained into the sump pump, keeping the basement dry.
