Water in your elevator pit isn't just an inconvenience, it's a safety hazard, code violation, and equipment destroyer. We provide comprehensive pit waterproofing solutions using advanced negative-side sealing technology at 2-3x lower cost than traditional injection methods.
PMCM technology bonds with concrete from the inside, creating a continuous waterproof barrier regardless of water entry point, more effective than injection methods.
Negative-side sealing costs significantly less than pressure injection methods. More of your budget goes to solving the problem, not expensive equipment.
We handle water removal, surface preparation, waterproof coating, sump pump installation, and mold remediation coordination, one contractor, complete solution.
ASME A17.1 requires pits to be kept dry. Our waterproofing brings your pit into compliance and keeps it there, preventing inspector citations and elevator shutdowns.
We inspect your pit to understand water intrusion source, extent of damage, and related issues. You receive a detailed proposal before any work begins.
We remove standing water, clean the pit, and prepare all surfaces for optimal coating adhesion.
Our technicians apply the negative-side sealing material according to manufacturer specifications, creating a durable waterproof barrier.
For pits requiring ongoing water management, we install sump pumps with oil separators. We verify effectiveness and provide complete documentation.
Standing water creates electrical hazards for technicians, can compromise safety device operation, accelerates corrosion of pit equipment, contaminates hydraulic oil, leads to mold growth, and violates ASME A17.1 requirements, potentially resulting in elevator shutdown.
PMCM (Pressure-Applied Masonry Coating Material) is applied to the interior pit surface, the 'negative' side relative to water pressure. It chemically bonds with concrete to create a waterproof barrier that handles water regardless of entry point, without requiring excavation.
Yes. For pits with ongoing water management needs, we install sump pump systems with oil separators. These OSHA-compliant systems handle residual water and prevent environmental contamination from hydraulic oil.
We coordinate with remediation specialists to address the complete problem, not just the water source. We manage the process so you deal with one point of contact.
Signs include: standing water in the pit, water stains or efflorescence on pit walls, musty odors from the elevator shaft, rust on pit equipment, oil-water mixing in hydraulic systems, or inspector comments about moisture.
We provide pit waterproofing throughout Washington State, dispatched from our Lynnwood headquarters.
