Available
Epirez is an Australian epoxy systems brand supplying structural epoxy grouts, floor coatings, concrete repair compounds, crack sealers, chocking compounds, and acid-resistant coatings to construction, mining, processing, and industrial maintenance operations across Australia. Alongside its epoxy range, Epirez also supplies cement-based grouts and repair mortars for projects where a water-mix, no-hardener product is the better fit.
Epirez Highway Patch is a rapid-set, hydraulic cement-based repair mortar — add water only, no resin or hardener component. It is formulated for fast-turnaround road and pavement repairs, with no corrosive compounds or noxious fumes.
Where this product is used
Used for rapid-turnaround repair of roads, pavements, and trafficked concrete surfaces.
- Pothole and pavement patching where the surface needs to reopen to traffic quickly.
- Edge repair and surface reinstatement on roads, footpaths, and hardstand areas.
- General rapid concrete repair where a cement-based (rather than epoxy) system is the better fit.

Selecting the right option
Highway Patch is a cement-based mortar — mix with water only, within the stated ratio, and place within the 10-minute working time; it can be extended with pea gravel for larger repairs. For general concrete repair away from trafficked surfaces, see Instant Grout (also cement-based) or Multi-Purpose Epoxy Concrete Repair (MULTI II) for an epoxy system. Prepare the substrate by saw-cutting, breaking out loose material, and cleaning before placing the repair.
