Lockport Waterproofing Machinery

The Contractor shall provide all labor, materials, equipment, and permits to seal, waterproof, and coat the interior of four (4) liftgate machinery pits at the Lockport Lock. The machinery pits are used to house cables, pulleys, hydraulic equipment to operate the lock?s gates. Due to cracks in the concrete, when the chamber is full, multiple leaks are present, allowing water to enter the pit. Due to the nature of equipment, there is grease and hydraulic fluid on the interior surfaces of the buildings.

The surfaces must be fully cleaned and degreased prior to application of any sealants, fillers, or adhesives to not compromise adhesion. Portions of walls are obstructed by structural steel which shall be left undisturbed, however the conduit can be dismounted and moved as necessary to complete this Work. The pits are approximately 20x20 ft, with a depth of 48 ft below surface grade. The concrete wall thickness is at least 3 (three) ft depending on location.
