Resins for Injection
Injeções em Estruturas
The concrete structures are easily attacked by infiltrations and attacks from the environment, mainly through cracks and cavities. Theses damages affect the durability and the integrity of the structure, as well as the appearance. For this the chemical industry has been developing several systems for cracking treatments through chemical injections that prevent the penetration of aggressive agents and protect the concrete structures.
Injection technology requires wise choice of materials to be used, this requires a precise knowledge of the problem cause and must be specifically designed for each structural part. The criteria for choosing the material to be injected must take into account the working conditions of the hardened resin.
