This wall is severely bowed. Our PowerBrace system can handle the load!
This sump is far too small. The water will fill this sump (liner) too quickly. The lid is also one-piece, which as you can see, doe not allow for easy access to the pump.
This old basement is ready for some ABS love!
If your sump looks like this, give us a call!
