    The Addagrip 1000 System Resin is a concrete repair system that consists of a specific resin and aggregate, developed to treat frost damaged, spalled or smooth concrete airfield pavements, concrete roads, concrete ramps and steps. 

    The system has been developed to treat top layer as well as deep damage and to seal small cracks and spalled surfaces on concrete airfield pavements. Applying the Addagrip 1000 System Resin onto the damaged or spalled surfaces of concrete will prevent further deterioration prolonging the life of the concrete.

    A major problem with concrete is that deterioration is caused by latent defects, chemical attack and frost damage, which over a period of time causes the top of the concrete to break-down. This breakdown may cause a safety or FOD (Foreign Object Damage) problem requiring removal of the affected areas.

    The Addagrip 1000 System Resin applied directly onto the prepared concrete pavement is designed to prevent further deterioration. Areas treated over the last twenty years at military and civil airfields have prevented further deterioration, prolonging the life of the concrete pavement by an estimated 10-15 years.  The Addagrip 1000 system seals and protects airfield concrete pavements that are suffering from ASR (alkali-silica reaction) more commonly know as 'concrete cancer'. By sealing and protecting the surface from moisture penetrating the concrete, the deterioration and service life can be extended cost effectively and and quickly.

    Preparation

    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.

    Application

    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.
