WPM® WATERTIGHT ELEVATOR PIT is a precast monolithic watertight concrete element.
Precast elements' water-tightness is achieved by using crystalline waterproofing admixture in the concrete. The product consists of a bottom, side walls, lifting hooks, and WPM® Metal Sheet Waterstop 125R installed on the side wall's upper edge - ensuring a watertight construction joint between the elevator pit element and the floor slab.
