Permanent Waterproofing & Concrete Restoration

Polyforce has recently completed a repair of a Mississauga salt storage facility. Polyforce Triplex application used consists of 1.8 MPa adhesive layer, thin patch repair, Fiberglass coating and protective 150 MPa basalt coating. Polyforce adhesive layer enables a thin patching application, which minimises the amount of demolition work required when compared to a tradition repair method. Polyforce Plus rust proofing extends the useful life of metal to 25 years. Structural geometry restorations were done with a use of Polyforce adhesive layer and regular cement. This treatment truly restores geometry and carrying capacity of decayed concrete structures while allowing the restoration to be done on concrete with exposed embedded metal surfaces. ----------- Surface Preparation ----------- The preparation work starts with surface shaving to remove contaminants and delaminated concrete. Shaving prepares the surface for patch application, while enhancing adhesion with Polyforce Plus to create a monolithic bond. Damaged embedded metal angles were cut and shaved in preparation for rustproofing and fiberglass repair applications. ----------- Polyforce Plus 1.8 MPa Adhesive ----------- Thin monolithic patch installation starts with a brush applied Polyforce adhesive layer. Visible wet spots is the coating of Polyforce Plus. ----------- Polyforce Black Polymer Cement Thin Application ------------ While adhesive is curing, a thin layer Polyforce Black cement is installed. Unique qualities of our polymer cement allow ease of installation without any extensive demolition. The sheer strength and elasticity of Polyforce Polymer cement are ideal for corner geometry restoration. ----------- Monolithic Patch with regular cement ----------- Deeper patches are installed with a use of regular cement with prior surface adhesive treatment. The most vulnerable area of the structure is the wall / floor joint. The applicator must take great care when preparing the area. Extra layer of Polyforce Plus as well as patch products are required to be installed to ensure best result. ----------- Patch metal / concrete structures ----------- The unique quality of Polyforce adhesive allow the patch to be installed on metal / concrete joints. ----------- Metal Polyforce Plus Rust Proofing ----------- The adhesive rust proofs the metal and creates a monolithic patch when restoring geometry. The entire metal / concrete slab becomes a monolithic structure. ----------- Polyforce Fiberglass protective coating ----------- Once the slab is restored, protective fiberglass installation begins. Polyforce Plus adhesive is brush applied to the concrete surface. Fiberglass sheets are installed while the adhesive is still curing. Fiberglass sheets are pressed with a thick brush to ensure uniform surface contact. The adhesive layer allows for 20 minutes of work time, after which the monolithic bond of concrete and the fiberglass sheet is formed. During the preparation of wall / floor joint a groove was saw cut into the corner. The bottom end of a Fiberglass sheet saturated with a Polyforce adhesive must be firmly pressed into the groove to form a protective barrier to avoid future delamination. The remainder of the slab and its corners are wrapped with a single sheet of the fiberglass cloth following previously outlined installation procedures. Floor wall joints are pressed into the saw cut groves saturated with a Polyforce Plus adhesive layer. All wall surfaces must be firmly pressed with a thick brush. Fiberglass sheets are left to cure. All corners where the fiberglass installation is terminated are finished similar to the floor / wall joints, complete with a saw cut groove saturated with Polyforce Plus adhesive to prevent any future delamination. ----------- Polyforce Basalt 150 MPa coating ----------- The final step of triplex installation is roller application of Polyforce Basalt coating. Impressive qualities of this protective layer create 150 MPa surface, impermeable to salt, water and mechanical intrusions. Completing triplex installation, 1.8 MPa adhesive ensures formation of a monolithic slab, truly restoring the structure to its original design. Polyforce coatings are rated to 25 years of freeze / thaw with 0% degradation, while remaining completely impermeable to elements. In before and after picture you can see the repair and rustproofing of imbedded metal rail. As well as sizeable repair of a slab corner, which are completely covered with protective triplex application. Should design require, the surface can be finished with a light gray color to match the existing concrete. Thank you very much for watching Polyforce Triplex repair application of a Salt Storage Facility.

The video explains the importance of creating an adhesive layer when doing concrete patching. Polyforce Plus bonds old and new concrete with 1.8 MPa adhesion, thus creating a monolithic concrete slab with uniform thermal elastic qualities. This means that during concrete expansion and contraction, the patch will not delaminate or crack. Monolithic bond also allow thinner concrete patch application during the repair, reduces (if not eliminates) demolition requirements and significantly reduces labor and effort. With use of fast setting concrete, patch areas can be open for use in 1 - 2 hours.

Waterproofing Expansion Joints & Ledge Beams We avoid costly excavation by working from the inside: we drill injection ports and inject our specialized liquid material which turns into soft rubber. It has tremendous adhesion power capable of binding cracked concrete, and displacing any accumulated water, not allowing it to re-enter. Our specialized application methods allow us to repair even those expansion joints that are located behind ledge beams. Interior Low-VOC Applications Fixing interior expansion joints in shopping centers, hospitals and clinics requires a special approach: low-VOC and fireproofing applications must be used, and work is normally carried out at night to minimize interference with the daily operations. Special care must be taken when working in medical facilities: the area being repaired must be kept extremely clean and noise kept to the minimum.

The patch was done in 2014 on the curved ceiling. Polyforce Plus material was mixed with Basalt and applied on to the ceiling without use of any forms. Adhesive strength of the patch is 1.5 times higher than the tensile strength of the concrete itself. The patch has the same thermal expansion efficiency as the concrete slab, which makes the whole repair a monolithic surface.

Elevator pits must receive regular maintenance to ensure optimal elevator equipment operation. When cleaning is done, it will be possible to see any issues - rusted metal, damp walls and calcium deposits - which indicate that the pit needs waterproofing. For a more precise diagnosis of the elevator shaft condition, an infrared scan is recommended, in order to design optimal engineering solutions.
