Project Description

Concrete Repair, Negative Side

 

The elevator shaft had significant leaks and exhibited degraded concrete. The site sits on an elevated water table and is especially sensitive to leaks.

The shaft was surrounded by a running undercurrent water. All repairs were done from the negative side (inside).

Polyforce Plus was used to stop the immediate leak with further patching of cavities and cracks. Fiberglass fabric, combined with cement board and Polyforce Plus applications were put on the walls to reinforce the weakened structure.

Technical Details

Facts

In accordance with third-party testing, the repaired surfaces are rated to the following:

Polyforce Plus

  • 25 years of useful life
  • 0% water permeation
  • Polyforce Plus is rated to expand and contract with concrete
  • The entire surface and volume of the slab is "monolithic"
  • Polyforce Plus compressive strength of 85 MPa
  • Basalt mix compressive strength of 150 MPa
  • Adhesive strength of 1.85 MPa (original concrete has only 1.2 MPa of a tensile strength, so the bond is stronger than the concrete itself)
  • Repair is 60% cost of a traditional repair

 

PolyFlex

  • Application of PolyFlex from the negative side reduces cost by 90% when compared to the traditional method of repair
  • 10 years of useful life
  • 0% water permeation
  • PolyFlex is able to expand and compress 200%
  • 200% expansion and compression does not affect adhesion or tensile strength of PolyFlex
