Concrete Welder Crack Repair
Available from Roklin Systems Inc.
Concrete Welder is a low viscosity, fast reacting urethane polymer that works well for concrete repairs because, as a very thin liquid, it can penetrate into small cracks and form a high strength adhesive bond between broken structures. It will flow underneath cracked or spalled concrete and seal the base against further erosion, as well as act to waterproof and seal concrete preventing liquids from streaming under the slab and creating voids. It has excellent chemical resistance to oils, hydraulic fluids, gasoline, salts, and antifreeze. It is also safe to use as it contains no solvents, has no odor, and a very low toxicity. Now available in 21 oz. cartridge kits for hand application as well as 10, 30 and 100 gallon kits for machine application.
