Power Coatings ltd is a waterproofing company that specializes in all forms of pits, shafts, lifts, and escalator pits. It makes no difference whether they're made of concrete, brick, or concrete blocks. We can waterproof lift pits that are more than 100 years old, 50 years old, or even just 5 weeks old. We've got tried-and-true answers for all of them. The waterproofing standards for Power Coatings are designed to produce a permanent waterproof seal around the soil retaining side of the lift pit walls (positive side) or within the lift pit's actual construction (negative pressure side).
