Project Description

Typical scope of balcony work consists of surface patches, crack repairs - which run from the unit wall out to the street - and surface non-slippery decorative finish. In some cases, the slope of the balcony floor needs to be reversed to drain the water away from the unit wall. Slope reversal is done by applying an adhesive layer together with polymer cement in a thin-patch configuration. 

To fully repair a cracked balcony, works must be done from the top (balcony floor) - normally just on the outside of the unit. When done from the bottom (balcony ceiling), the crack must be treated both inside and outside: if only the inside is done, the crack will spread into the inside and undo all the work. 

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.

Technical Details

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.

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