Basement Waterproofing Photo Album: Commercial Building Waterproofing in St. Louis

The lower level of this commercial building needed waterproofing in the basement before the restaurant was built out. One area that needed special attention was the elevator shaft. The perimeter of the basement foundation needed waterproofing without obstructing the function of the elevator. Our WaterGuard™ waterproofing system met this challenge because it is encapsulated within the re-pour of the basement floor. The water coming in the basement could be seen going across the top of the footing once the basement floor was broken out. With the WaterGuard™ in that exact place, all the water will now drain into the TripleSafe™ sump pump. For this large area two TripleSafe basement sump pump systems were installed. Drilling the four discharge lines, 2 per TripleSafe™, to the exterior through a thick commercial building foundation was also labor intensive.

Wide Footing

For larger structure than homes, the footing is larger to support the large mass of the building.

Basement Floor Removed by Stairway

The removing of the floor to make room for the installation of the WaterGuard™ basement waterproofing system means going into some hard to reach spaces.

Closet Area by Stairway

The entire perimeter of the basement floor needs to be removed so a continuous run of WaterGuard™ can be installed to drain water that is leaking into the basement. The water must travel inside the WaterGuard™ basement waterproofing system and drain at the sump pumps.

Under the Stairway

WaterGuard™ must be installed to complete the waterproofing system even in hard to reach spaces. It will also need to go under walls.

2 Sump Pumps in Each TripleSafe

Each basement sump pump systems called TripleSafe has two sump pumps. Each sump pump is on a sump pump stand to hold it properly in place in the sump pump pit. Also, one of the two sump pumps is on a 2nd stand to double the height so the switching float will not go on unless there is a higher than expected water level leaking in to the basement. That is why each sump pump has its own discharge line to the outside.
