About this Product
webertec EP TAG is a specially formulated epoxy resin system for securing horizontal fixings, such as dowel bars, starter bars, threaded studding and bolts into concrete or brickwork. A high strength, corrosion and chemical resistant anchoring is obtained where speed of installation and early application of load is required. The thixotropic nature of the material ensures that the mixed resin stays in the hole after injection.
Conforms with BS EN 1504:6.
Features and Benefits
- Quick and easy cartridge loading with mixed material
- Large pack economy with the facility of small mixes to minimise wastage
- Easy to mix and place.
- Very high strengths - approximately 60 N/mm2 at 4 days
- Minimal shrinkage - when used in anchoring, the grout remains in contact with all faces of the hole and fixing
- Can be used for injection of larger cracks in concrete or brickwork where low viscosity resins are not appropriate
- Thixotropic nature ensures anchor grout remains in the hole
- Epoxy resin based, able to withstand dynamic and cyclic loading on bolts

Declaration of Performance (DoP)
Preparation & Application
Holes should be made with a rotary percussion drill and must be clean, dry and free from dust. Diamond drilled holes must be roughened.
Bars or bolts must be free of rust, scale, grease, oil or other surface coating or contamination; best results are obtained to freshly-cleaned, bright steel.
For optimum performance smooth bars should be deformed, i.e. threaded.
Mechanical mixing is recommended. Use a slow-speed stirrer or an electric drill with a stirring attachment producing 200 to 400 rpm.
If mixing by hand, thoroughly stir the resin with a flat bladed palette knife. Add the hardener and mix together thoroughly before adding the powder filler. Mix until a smooth, even consistency is achieved (approx. 10 minutes).
NB. If smaller quantities are required the mix ratio is 4 resin: 1 hardener by volume Add filler to suit.
The gelation time depends on temperature; a guide is given below but do not apply below 5°C.
5°C: 12 hours
10°C: 4 hours
20°C: 1.5 hours
These values are very bulk-dependent, particularly at lower temperatures. Large quantities can gel up to 25% faster than suggested. Do not mix more material than can realistically be used within the setting time.
Transfer the mixed grout to the assembled cartridge. Insert the plunger, load the cartridge into applicator gun and then pump the grout into the back of the hole, ensuring that it is completely filled and no voids are left. Leave the grout just short of the face of the concrete and then insert the fixing, using a slight twisting motion to displace the grout. Once the fixing has been placed, do not disturb until the grout has set.
Use webertec solvent 3 to clean all equipment before the material sets.
Packaging, Health & Safety
webertec EP TAG is supplied in a 6.4 kg pack. Each pack contains 2 tins of resin, 2 bottles of hardener and 2 packs of filler to enable the pack to be split into 2. Follower plates are supplied for ease of filling cartridges.
Coverage / Yield
Each 6.4 kg pack produces 4 litres resin.
Storage and Shelf Life
The shelf life of this material is at least 12 months if stored in a cool dry place.
Health and Safety
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.
