Sump Pumps Photo Album: Groundwater Seepage Causing Sagging Floors

Water was seeping into this crawlspace in Savannah, GA and the moisture had caused the floor to start to sag in one area from weakness in the floor. In order to help control the water seeping into the crawl space, our team installed a perimeter waterproofing system and a layer of drainage matting. To support the sagging floor, SmartJack Support was installed.

Before Drainage System Installation

This crawl space had a small plastic vapor barrier to cover the ground, but there was nothing in place to remove any entering water, so it would collect in pools on top of the liner.

After Drainage System Installation

This is a view of the same area of the crawl space but with a perimeter waterproofing system installed. Visible in the photo here is the drainage matting and a sump pump next to the pillar.

Before SmartJack Support

This area required additional support to stabilize the floor above that was sagging.

After SmartJack Support

This area of the crawlspace had SmartJack support posts installed to supplementally support the floor that had been weakened by moisture over time. The layer on the ground is drainage matting, and under that is a perimeter drainage waterproofing system to remove floodwaters.

Drainage System Connected to Sump Pump

Under the brown drainage matting layer is a perimeter drainage system. This system drains water into the sump pump, effectively keeping rising groundwater out of the crawl space.

Drainage Rock

Drainage rock is used to cover the perimeter waterproofing system, aid water flow into the drainage system, and keep the system itself from floating with extensive flooding.
