Elevator pits are often the lowest point in a building, making them natural collection points for groundwater. Water in an elevator pit isn’t just a nuisance; it’s a major mechanical and electrical hazard. At Basement Expert, we specialize in Negative-Side Injection and active pumping for elevator pits. We seal the concrete from the inside out using specialized resins that stop water under high pressure, ensuring your building stays in compliance and your elevators stay running.
