Common Usage
Series 489 is a durable polymer concrete which exhibits fast curing and minimal shrinkage. Ideal for the rehabilitation of severely eroded concrete or for the corrosion-proofing of new concrete where superior chemical resistance is required throughout the complete topping system. Series 489 is ideal for pump and pad rebuilds in areas of strong acid and caustic exposure. Use to cast sumps and trenches off-site for time and labor savings.
