weber.tecEP IK 

The weber.tec EP IK contains all materials, application gun, and the ancillary items that will normally be required to carry out an efficient on-site repair of cracked concrete at widths down to approximately 0·5 mm. The weber.tec EP injection resin is in thixotropic form this allows application where it is not possible to completely seal the cracks, for example: cavity walls and chimneys.

• Easy to use
• All materials required, together with mixing bucket and application gun, packed in a single carton
• Comprehensive easy-to-follow instructions with each kit
• Significant cost reduction compared to other techniques

Resin injection is particularly useful as a method of carrying out structural repairs of concrete and masonry. It forms a bond between the broken sections stronger than the material itself and seals the crack against ingress of water and aggressive agents, which may have a deleterious effect on reinforcement.

It is generally accepted that cracks in reinforced concrete narrower than 0·2mm need not be injected and some form of surface sealing is normally sufficient. Before deciding to inject cracks it is most important to establish the cause of cracking. Ensure that they are not still moving by using suitable tell-tale devices. If movement is occurring the crack should be treated as a normal movement joint.

The crack and surrounding surface must be thoroughly clean, dry and all loose debris removed. weber.tec filler is then used to seal the surface and fix the injection nipples. Once the weber.tec filler has hardened, which normally takes about an hour, the injection resin is mixed* and placed in the assembly cartridge. It is then simply a matter of pushing the plastic tube over the nipple, clipping firmly in place with jubilee clip provided, opening the restrictor clamp and gently pumping in the resin using the hand operated skeleton gun. Starting at the bottom so that air is displaced upwards, each nipple is sealed as it becomes filled.

The following day the nipples may be broken off and depressions filled with further weber.tec filler. For a smooth matching finish, the crack surface should be ground off using a mechanical grinder or similar tool.

*NB Stir the resin thoroughly before adding the hardener.

Most of the components are disposable so cleaning is minimised but any spillages and mixing tools should be cleaned with weber.tec solvent 3 before the resin sets.

Contains epoxy constituents. Refer to information supplied by manufacturer (see Material Safety Data Sheet).

All skin contact with epoxy resin products should be avoided. Barrier creams should be used and operatives should wear protective clothing including gloves. Working areas should be well ventilated.

The hardener content is alkaline and labelled as corrosive. The resin content is labelled as an irritant. The flash point of all components is in excess of 100°C. In the event of fire use foam, dry chemical, carbon dioxide (CO2) or water fog extinguishers.
