Joint Seal Waterproofing is a Toronto-based company, specializing in waterproofing elevator pits. Our services cover a vast geographical area, from Hamilton to the City of Toronto, and the surrounding GTA communities.
For over five years, we have been providing elevator waterproofing in Toronto and the GTA. We specialize in shaft concrete repair, restoration, and crack injection. High-strength concrete adhesives allow us to perform all concrete repairs from the inside of the shaft, ensuring long-lasting results. Use of crystalline coating restores water impermeability of the shaft wall.
Elevator Pit Cleaning
We offer elevator pit cleaning as part of annual maintenance, or as part of our waterproofing process. A clean elevator shaft prolongs the life of sump pumps, increasing the efficiency of drains.
We offer this exclusive thermographic scanning service of commercial-grade quality. Our waterproofing solution experts rely on years of field experience, supported by high-end scanning equipment. We always provide a detailed inspection summary report, supported by infrared scans, presenting a more in-depth view of proposed repairs.
Waterproofing Elevator Pits
Depending on the condition of the shaft and its characteristics, different procedures are followed to ensure long-term elevator pit waterproofing. Please refer to the Repair Methods section below for more details.
No matter how severe the leaking, we can help. Long-lasting elevator shaft waterproofing is made possible through specialized applications and high-end waterproofing materials.
Most of the elevator pit waterproofing is done for wall/floor corners (cold joints) – a weaker area in a concrete surface, where most leaking occurs. A multi-layer waterproofing repair method is applied to ensure long-term waterproofing: concrete adhesive, patching, primer, fiberglass, and basalt.
Wall/Floor Crack Repair
When elevator shaft waterproofing is required due to cracks on elevator shaft walls or floors, the cracks are first prepped and then filled with specialized elevator pit waterproofing materials: adhesive, polymer cement, and primer. For all patches of less than a ¼ inch thick, polymer cement is used.
Block Wall Waterproofing
Waterproofing elevator shafts made of block walls requires a special procedure. First, to make sure no water accumulates inside the block wall, drainage is installed at the bottom. Next, appropriate waterproofing materials are applied. Some repairs include application of crystalline, such as Xypex or Hydroseal.
For piston-operated elevators, a specialized procedure is followed to ensure long-lasting elevator pit waterproofing. Any accumulated liquid is pumped out of the housing around the cylinder/piston assembly, the void is cleaned and injected with a soft rubber.
