Raised Floor Systems

If subsurface water is penetrating your basement floor, the best solution may be to rise above it. Installing a raised floor drainage system creates a space between your basement floor and the wet surface below.

Closed Pressure Relief System /French Drain

When a basement is built where there is an underground water source, a spring stream or even a high water table hydrostatic pressure can cause water seepage, either where the wall meets the floor or even through the floor. One solution is for the pressure to be relieved and the water diverted to where it can be pumped out of the basement.

Underground Parking Garages

The decks of underground parking garages must be protected from the effects of weather, traffic, and road chemicals. This environment calls for a waterproofing method that is stronger than a simple coating. We use cementitious capillary waterproofing products that become an integral part of the concrete, forming a complete body of strength and durability. Its waterproofing and chemical-resistant properties remain intact even if the surface is damaged.

Elevator Pit Waterproofing

At the base of an elevator is a pit that extends 10-20' below the bottommost floor to accommodate counterweights, wiring, and a large hydraulic jack stand. These pits are as susceptible to water penetration as any other below grade basement area. We have several methods for addressing water in an elevator pit, depending on the sound of the penetration.

  • Drill through the concrete floor and pump in bentonite (also known as hydroclay) a highly water-absorbent clay;

  • Use a penetrating mortar that will create a waterproof seal to ensure that a newly installed or replaced hydraulic elevator jack will remain watertight in the pit;

  • At pit installation or repair, include a hydrophobic admixture to the concrete, keeping water out and forming a protective barrier around any rebar, resulting in highly effective concrete corrosion inhibition.

  • Create closed pressure relief system to carry water away from the pit.
