A-Joint® Repair is the 2-component repair mortar for restoring damaged or washed-out joints in existing paving. It also fills shallow joints from 10 mm and is trafficable again after 24 hours.
During repair, routing out existing joints to 25 or 30 mm is often not feasible: too time-consuming, too expensive, or technically impossible with sensitive natural stone. A-Joint® Repair powered by ECCO works from a joint depth of 10 mm, allowing you to carry out much shallower repairs. The fine sand structure ensures strong adhesion to the joint sides, even with narrow joints from 3 mm.
A repair joint is only durable if it bonds to the existing joint. A-Joint® Repair powered by ECCO is built on that bonding strength: the epoxy resin mortar bonds old and new joint material into a single whole. Ideal for repairing frost and thaw damage where the outer centimetres have been washed out but the underlying joint is still intact.
For public roads, city squares and car parks, every day the area is closed counts. A-Joint® Repair powered by ECCO is walkable after 6 hours and drivable after 24 hours at 20°C. With a load capacity of up to 25 tonnes and resistant to street sweepers and high-pressure cleaners, suitable for the heaviest loads in public spaces.
A 2-component pointing mortar that repairs washed-out and crumbling joints with strong adhesion to the existing joint, in shallow joints from 10 mm.
Do you want to use A-Joint® Repair powered by ECCO in your project, but don’t want to be left with leftovers or have to reorder? Calculate exactly how much you need in advance with this handy product calculator.
A-Joint® Repair powered by ECCO is used to repair existing, damaged joints, not to joint new paving. It is a 2-component (epoxy resin) repair mortar that bonds to the old joint.
