High-pressure foam method for the fracture and stripping of concrete structures Available to Purchase

A controlled foam injection (CFI) method has been developed, tested and demonstrated to have capabilities to fracture and strip reinforced concrete structures such as pavements and bridge decks. The method uses a high-pressure foam to initiate and propagate fractures in concrete structures. In contrast to methods using explosives to fracture and break concrete or rock, the CFI method does not generate ground vibrations or airblast. The foam components are biodegradable and environmentally benign. The CFI method can be used for demolition work or the repair and rehabilitation of degraded concrete structures.
