Power Coatings ltd specializes in waterproofing all types of pits, shafts, lifts & escalator pits. It doesn’t matter if they are constructed from concrete, brick, or concrete blocks. We can waterproof lift pits that are 100 years old, 50 years old, or just 5 weeks old. We have tried and tested, proven solutions for them all. Power Coatings waterproofing specifications are designed to form a permanent waterproof seal around the earth retaining side of the lift pit walls (positive side) or within the actual construction of the lift pit (negative pressure side).
