How do you waterproof a lift pit?

Lift pits are notoriously prone to leaks as they are the lowest point of a building, often sitting in the water table. Because they endure high vibration and oil contamination, standard tanking often fails. We typically treat lift pits using negative side waterproofing combined with polyurethane resin injection to seal cracks and construction joints. We also use oil-resistant waterproof slurries to ensure the coating isn't degraded by hydraulic fluid leaks.
