2466 Eglinton Ave. E - Elevator

The challenging aspect of repairing elevator shafts is having to work from the negative side (inside), for obvious reasons. There were leaks through floor-wall cold joints and floor cracks.

Floor-wall Cold Joints

The following procedure was applied to repair these cold joints:

• All of the corners were cut into the corner and adhesive was injected. 
• Patching material was applied, while the adhesive was still curing.
• Polyforce Plus Primer was painted over the patching.
• Fiberglass was installed to cover the corners.
• Finally, fiberglass was painted with basalt for further reinforcement and protection.

Polyforce Plus Adhesive

The use of specialized product, Polyforce Plus Adhesive, permits restoration of the carrying capacity of the slab through monolithic concrete patching and crack repair, providing an alternative to complete slab recasting.

Polyforce Plus coating is tested to provide 25 years of freeze and thaw waterproofing with no degradation and water permeation. This material is rated to expand and contract with concrete, ensuring long-lasting adhesion of concrete patches due to its impressive 1.85 MPa adhesive strength (compared to 1.2 MPa tensile strength of the original concrete). This makes the patch and the old concrete slab work as one.

Polyforce Plus, when mixed with basalt, achieves compressive strength of 150 MPa, making it ideal for surfaces that suffer high mechanical intrusion or increased and prolonged exposure to light acids.

Versatility of application and high strength of installation produce significant cost savings, when compared to traditional concrete repairs.

Polyforce Polymer Cement

Polymer Cement was designed for fast and thin patch applications. When combining patch application of Polymer Cement with high-strength industrial concrete adhesives, many applications which would otherwise be too expensive to execute become cost-effective and feasible. Most typical applications include valley resurfacing, slope reversals, crack repair patches, and stair and balcony repairs.

Polymer Cement is designed to perform in thicknesses ranging from 0.01 inches to 0.25 and beyond. The material performs at 99% dry finish volume.

Polyforce Plus Primer

High-strength concrete primer is designed for two purposes: concrete waterproofing membrane and primer adhesive layer.

• Surface application of Polyforce Primer provides Waterproof Concrete Embedded Membrane rated to withstand 25 years of freeze and thaw cycles.
• Increased adhesive qualities of the primer eliminate surface debonding of top coat paint application.

Polyforce Plus, when mixed with basalt, achieves compressive strength of 150 MPa, making it ideal for surfaces that suffer high mechanical intrusion or increased and prolonged exposure to light acids.
