TP-EPOXY INJECTION

Epoxy-based crack injection material for structural strengthening

An epoxy-based, two-component, low-viscosity injection material developed to be injected into cracks under pressure.

Areas of Use

• It penetrates the breaks and cracks formed in the damaged concrete, columns, beams, walls and similar structural elements into which it is injected, filling, repairing and bonding them.

Advantages

• Penetrates deep into capillary cracks.
• Has high mechanical strength.
• Provides high adhesion to concrete.
• Has low viscosity; easily injected at low pressures.
• Contains no solvent.

Consumption	Varies according to the depth of the break or crack.
Shelf Life	Can be stored for 12 months in its unopened original packaging in a dry environment at temperatures between +5°C and +25°C. Opened packages must be used immediately.

Application

The cracks are widened with an angle grinder. Their interiors are cleaned out with air. The outer faces of the cleaned cracks are sealed with EPOXY REPAIR epoxy putty. After approximately 2-2.5 hours, once the packers have been mounted with the aid of a drill, TP EPOXY INJECTION injection resin is injected into the packers by means of an injection pump. Application tools: with an injection pump.
