Concrete Water LeakPolyurethane PU Injection

Stop leaks in balconies, retaining walls, dam and reservoir walls, tank walls, carparks, building walls and concrete floor slabs.

What’s Concrete Water Leak Polyurethane PU Injection ?

Polyurethane Resin is used to seal and eliminate or reduce water leakage from concrete cracks and joints and can also be injected into cracks that experience some degree of movement.

FCS Concrete Repairs have the knowledge and experience to successfully carry out Polyurethane Resin Crack Injection Repairs including dry crack repairs, sealing of
water leaks, and stopping gushing water leaks and flows.

Polyurethane Resin is used to seal and eliminate or reduce water leakage from concrete cracks and joints and can also be injected into cracks that experience some degree of movement.

Benefits & Process

Hydrophilic (hydro meaning ‘water’, philic meaning ‘has an affinity for’) resins seek out water in a crack. They chase the water and absorb into the tight micro – cracks and pores of the concrete. Hydrophobic (hydro – water, phobic – fearing) resins repel water in a crack. They resist movement towards wet areas and will not absorb into tight micro cracks and pores in the concrete. All polymer repair materials get their mechanical bond in these rough areas (if the resins can penetrate them).

Since hydrophilic resins seek out water, they absorb deep into the pores and micro cracks of concrete. This gives hydrophilic resins a tenacious bond to the wet concrete. Since hydrophobic resins repel water, they will not penetrate these areas. They may be forced in using high pressure, but the water will act as a bond breaker between the polyurethane foam and the concrete resulting in extremely low bond strengths.

The basic procedure for polyurethane injection consists of first gaining control of the leaking water if leaks are high, followed by pressure injecting resin to seal the cracks.

Our process considers a tailormade solution for your
concrete repairing need. This is how we approach each project:

STEP 1: INVESTIGATE

We conduct professional investigations and diagnosis of the issue in order to identify the source and cause. Identifying the source and cause of the issue is vital in finding the best solution and preventing further problems. Once the cause of the issue has been identified and confirmed, we then determine the optimum repair system for each specific application. These processes are often performed under the guidance of highly qualified engineers, designers or architects.

STEP 2: RECOMMEND A SOLUTION

We access the most advanced technologies in concrete Restoration and Preservation from leading manufacturers worldwide to reinstate the structural integrity of any concrete structure. We strictly adhere to all manufacture and design specifications ensuring that the right system is used and applied correctly for your project.

STEP 3: GO THE EXTRA MILE

Longevity and continuing performance of the repair can be at risk if protection and preservation measures against future potential contamination threats are not adequately addressed. We also conduct operational and environmental investigations to ensure that future contaminant risks are specifically controlled using the most effective treatments available.
