Addagrip 1000 System

Addagrip 1000 System application diagram

The surface preparation to the concrete surface is carried out by applying controlled hot compressed air. The Addagrip Hot Compressed Air System is a combination of propane gas and compressed air ignited in a chamber. The mixture burns at a temperature of approximately 1000°c with the exhaust exiting the chamber at a rate of 350m per second.

As the heat blast comes into contact with the concrete pavement it causes any water, oil or liquid contaminants to vaporise from the top few millimetres. These quickly evaporate from the surface and are blown away by the heat blast, leaving the surface capillary pores empty and open, ready to receive the Addagrip 1000 System Resin.

Addagrip 1000 System Resin should be applied directly onto the warm and dry prepared surface. As the concrete cools the Addagrip 1000 System Resin will be drawn down into the open and empty capillary pores. This penetration of resin, typically 2-3mm, will lock into the structure of the concrete preventing migration of moisture.

Addagrip 1000 System Resin should then be applied at a rate to be agreed, coverage rates will depend on the porosity, texture and size of aggregate to be used. Application of the resin is by roller and squeegee or spray machine to large areas.

The Addagrip 1000 System Resin should then be saturated with a chosen washed, clean and dry aggregate. Allow the resin to cure, approximately 8 hours at 15 °C. Sweeping and vacuuming as required should then remove all excess aggregate.
