Drizoro - opravná malta Maxrite HT

Maxrite HT is a repair mortar for application in layers up to 10 cm thick (without the use of formwork). It is available as a one-component cement-based product to be mixed only with water. It is modified with microsilicates and polymers, reinforced with fibers and contains anti-corrosion inhibitors. In particular, it is used to repair structural concrete that is exposed to an aggressive environment. Provides additional protection for steel reinforcement. Maxrite HT has thixotropic properties and a long pot life, making it possible to repair concrete on vertical surfaces.

Application

• structural repair of concrete with corroded reinforcement (marine environment, ports, dams, bridges)
• repair of concrete structures undergoing the carbonation process
• repair of concrete damaged by de-icing salts, multiple loads
• repair of concrete element in prefabricated units
• maintenance of industrial surfaces damaged by aggressive surroundings, atmospheric pollution, acid rain
• prevention of corrosion caused by chlorides and other aggressive corrosive agents - thanks to anti-corrosion inhibitors
• protection against corrosion the rod in the reinforcement and damage after freezing and thawing cycles - thanks to water resistance

Due to the high adhesion to concrete and the bar in the reinforcement, the stresses are transferred to the repaired structure. Maxrite HT is characterized by good chemical resistance to aggressive agents, including salts, sulfates. It can be applied by hand or by wet spraying.
