Restore deteriorated concrete. Structural repairs, cavity filling, patch coatings, and waterproofing for damaged surfaces. Extend structure lifespan by decades.
Water infiltration causes steel reinforcement to rust. Expanding rust cracks and spalls concrete. Structural integrity compromised.
Surface concrete breaks away in chunks, exposing rebar. Creates safety hazard and accelerates further damage.
Poor curing or air pockets leave voids and weak spots. Water seeps in and weakens concrete from inside.
Atmospheric CO₂ reduces concrete pH, triggering rebar corrosion. Old concrete becomes weak and brittle over decades.
Clean out spalled area. Apply epoxy coating to exposed rebar (corrosion inhibitor). Fill cavity with repair mortar. Seal surface.
Inject epoxy or polyurethane grout into honeycombs and voids. Restores structural integrity and blocks water ingress.
Apply protective coating over degraded concrete. Prevents further water infiltration and stops corrosion progression.
Epoxy coating for exposed rebar. Inhibits corrosion and creates bonding surface for repair mortar. Apply before patching.
Low-viscosity epoxy for injecting into cracks and voids. High strength. Bonds to concrete and fills 0.3mm cracks.
| Step | Activity | Duration |
|---|---|---|
| 1. Assessment | Visual inspection, rebar exposure, depth of spalling | 1 day |
| 2. Surface Prep | Remove loose concrete, clean rebar, dry surface | 1-2 days |
| 3. Rebar Protection | Apply HC710 epoxy primer to exposed rebar | 1 day + 12hr cure |
| 4. Fill Cavity | Pack repair mortar or epoxy grout into void | 1-2 days |
| 5. Topcoat | Apply HP410 coolcoat for waterproofing | 1 day + 7 day cure |
| Total | From start to finish | 5-10 days |
