RESIN INJECTION
Resin injection is a repair technique employed to waterproof and repair cracks, voids and defects in concrete and masonry structures.
Shrinkage and movement in concrete structures may lead to water ingress, structural in stability, corrosion and damage to steel reinforcement, and in some cases collapse.
Modern industrial chemistry has developed a range of single and multi component resins that can be utilized in the repair of Tunnels, reservoirs, basements, pipelines, lift & escalator pits, structural concrete slabs and elements.
Using a range of electric and air driven pumps the injection pressure can be controlled to deliver controlled amounts of resin or cement based materials to a Varity of voids fishers and cracks.
Larsen Contracts have many years field experience and have developed methodology in many different applications to resolve a verity of problems in, leaking basements, tunnels, manholes, lift pits, culverts, reservoirs and bridges.
The injection of high strength and flexible resins have be used to repair structural elements by stopping and preventing the ingress of substances that cause decay in concrete such as de icing salts on road bridges, aggressive chemicals in chemical and pharma production and most commonly carbon dioxide that causes carbonation in reinforcing steel in insitu concrete structures.
