Modern concrete was patented in the 1800s by an English cement maker and a French gardener, but cement has been in use for more than two thousand years. In Rome it was called opus caementicium, and it’s the primary material in the Pantheon dome and the grand Colosseum.
Concrete, more than any building material, has allowed man to build truly incredible things. Industry and commerce depend on the structures we built with concrete. Concrete’s hard stuff, but with time, water, wear and tear, and ground action even the largest concrete structures and surfaces will begin to crack.
Epoxy injection is an economical method of repairing cracks in concrete structures, slabs, and concrete surfaces exposed to the elements – like piers, stanchions, and support pylons. Whether it’s your primary office, manufacturing facility, refinery, parking structure, foundation, or other industrial placement epoxy injection can help to stall and even reverse some of the damage incurred by your property.
Before attempting to restore a crack, it’s critical to understand the cause of the crack. Is it movement or settling, excess strain or weight load, or is it degradation of the core material by water or environmental forces? In some of these cases epoxy injection will resolve the issue, but in others an engineer may need to be consulted before proceeding. Engineers will be able to certify the safety, stability, and viability of your facilities before injection or further action is taken.
If water is a particular concern for your facility, then Polyurethane Grouting is another technique you should consider. It works by cutting off water flow through concrete joints and cracks, or filling the voids beneath and between slabs and within the subsurfaces of walls. The water-impermeable grout is injected through a pre-drilled hole, and with epoxy injection is often used to provide waterproofing in large infrastructure projects like traffic tunnels and subterranean resource passages and facilities.
Polyurethane grouting also sees a lot of use in roof slabs, drainage-adjacent surfaces (like walls with an attached drainage pipe), and other surfaces exposed to water, or prone to accumulations of resting water. It is also used in tandem with Epoxy Injections in cases where pre-existing fractures are present, and elastomerics where there’s no need to add structural support, but water needs to be kept out of the treated area.
