Elevator Pit Waterproofing

Elevator pits are typically the lowest part of any building, and, as a result, are susceptible to flooding and water infiltration. Excessive and prolonged moisture in a confined space can lead to bacteria and mold build-up and the odors they produce, as well as corrosion and damage to the elevator pit equipment, including the cylinder, support steel, springs, and oil supply line. Repairs or replacements to any or all of these components can run into tens of thousands of dollars.

Stache Drilling & Elevator Services can put an end to these moisture issues. We have been working exclusively on elevators, elevator pits, and the subsoil under elevator pits for 30+ years. Our water stop injection system is field proven and we always guarantee a dry pit! Unlike a full replacement of the concrete, our process requires minimal elevator downtime. Imagine your elevator pit transformed from damp & smelly to dry, clean, and freshly painted.

Testimonal From A Recent Customer

"We had an elevator cylinder fail in our hospital and the elevator company removed the damaged
cylinder. When they did, it was discovered that we had a significant gravel in the pit and a groundwater
problem that prevented the elevator company from installing a new cylinder. Stache Drilling came on site and offered to assist. We cut an extra hole in the floor of the pit to divert some of the groundwater so that Brent and his crew could evacuate the gravel from the pit and insert a new
casing. Once the new cylinder was installed we couldn’t stop the flow of water from the relief hole we
cut. We were pumping at least 62 gallons per minute of water out of that hole. Once again Brent
Stache was called to help us stop the flow of water. He and his team were able to drill holes in the floor
of the pit and pump in a waterproofing agent which eventually stopped the flow of water. Our elevator
pits are now drier than they have ever been!! Our water problems have been solved thanks to Stache
Drilling Elevator Services."
