New Project - Basement Waterproofing

These pictures serve as a record of our recent waterproofing project from June 2-5, 2008. All American Basement Waterproofing of Wadsworth, Ohio did the work, and I was impressed by their diligence. They stayed on the job until finished.

This basement serves as our preschool, and is in the original 1953 building. Good drainage was not designed into the plan, so we have had frequent flooding problems over the years. Not good in a carpeted preschool area. These pictures show how the job was done.

The jackhammers drilled about a foot around the outside walls, source of the leaking. Hand digging would be done to provide space to lay a gravel bed and perforated PVC pipe.






Next, holes were drilled at the base of the digging. This will permit the water that normally builds up outside to come into this new drainage area and into the perforated pipe.
















These two pictures above show the plastic sheeting that covered the drainage holes and the course of the pipe which will take the water into a sump in the stairwell.


The picture to the left shows the sump in the stairwell next to the preschool room. Water from all the pipes drain into this plastic tub. The pump is placed into the tub to send the water up a few feet into the outside rain gutter system.

In the event that a heavy storm knocks out electrical power, the pump has a battery backup as you can see to the left.











Finally, the water is pumped up and outside. The thinner pipes come from the sump, and are joined to the larger rainwater downspout system.
