Under traditional repair methods, patching requires a minimum of two-inch demolition in the affected area. Besides, patching a wall poses an added challenge - lack of adhesion, and non-specialized material running out without use of forming. The use of our unique products, Polyforce Plus Adhesive, and Polyforce Polymer Cement, permits thin-patch applications, even on walls and ceilings, without use of any forming or concrete injection, making the job much more cost-efficient and faster. The combination of Polyforce Plus Adhesive and Polymer Cement creates a monolithic patch which is able to restore structural integrity of repaired slab.
Our patching process is as follows:
- Delaminated and unsound concrete is removed.
- Polyforce Plus Adhesive is applied as an adhesive layer. Its impressive 1.85 MPa adhesive strength ensures monolithic adhesion
- Within 40 minutes, the actual patch is applied. On very thin patches (less than a ¼ of an inch), Polyforce Polymer Cement is used; otherwise, regular cement.
Traditionally speaking, two slabs of concrete cannot be glued together when there is a crack. This, however, is not the case through the use of our specialized materials which make monolithic 1.85 MPa adhesion possible. Not only can we repair concrete but also restore it to its original condition, even when wet. It works both on single cracks and concrete surfaces with multiple issues - no need for complete resurfacing. Such rehabilitation is even done on concrete surfaces that are combined with metal structures.
The following process is applied:
- Cracks are routed with a saw to create a V-groove to prep the area for repair.
- The crack is filled with Polyforce Plus Adhesive which ensures immediate and durable monolithic adhesion
- The crack is patched with the Polyforce Polymer Cement.
- Waterproofing Polyforce Plus Primer is applied over the area.
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.
