Tecgrip V, part of the Tecgrip range of polyester resin anchor grouts, is used for the fixing of steel bolts and bars into pre- drilled holes within concrete, rock, brickwork, stonework, masonry or other substrates capable of supporting the required load. Formed anchors are high strength fixings which are resistant to corrosion and may be loaded quickly after installation. Placed anchors are resistant to vibration, do not exert expansive forces and may be designed for under water installation.

Tecgrip V consists of a low viscosity polyester resin plus a catalysed filler. The two components are mixed to produce a filled resin grout, which may be poured or pumped into suitably prepared anchor holes. The mixed grout is coloured dark grey and is used for downward facing holes where the hole diameter is up to 25mm greater than the bolt or bar diameter.

Typical Anchor Properties @ 20°C

Anchor Strengths

Deformed bar to BS 4449 in unreinforced 20N/mm² concrete, holes drilled by rotary percussive method on air flush.

Parameters controlling Uniaxial Pull Out Load:

• Type and strength of base material
• Length of resin anchor bond
• Hole forming or drilling method
• Type of fixing, bolt or bar

Safety Factors:

• Non critical applications : 1.5 minimum

Standards

Tecgrip V has been tested in accordance with the appropriate parts of BS 6319, BS 5080.

Anchor Installation

Holes and Bar Types

Holes should be drilled using rotary percussive drills with air or water flush. The drill bit should be of the integral type with an elliptical head. Holes which are diamond cored should be under-reamed or roughened. Holes which are drilled with a rotary percussive non-flushing drill bit should be cleaned using a steel rotary brush. Loosened dust should be blown out of the hole using compressed air through an extension tube reaching to the bottom of the hole. Cast holes should taper so that the hole diameter is smaller at the mouth than the bottom.

Steel bars used for anchoring should be deformed such as those manufactured to BS 4449. Threaded bars may be used. When using smooth bars an extra safety factor should be incorporated into the anchor design.

Grout and Bar Placing

Place contents of resin can into plastic container or pail. Slowly add catalysed filler whilst mixing. Continue mixing until a uniform colour is achieved. Correct mix proportioning must be used to achieve the designed anchor strength. Pour mixed grout into prepared holes, rodding if necessary to ensure grout flows to the bottom of the hole. Once grout has been placed insert bar into hole and gently twist and press home to the required depth. The bar should be left undisturbed until the grout has hardened.

Equipment should be cleaned with Solvent prior to grout hardening.

Precautions

Temperature in Use

Tecgrip Products may be placed at temperatures between 5°C and 35°C. Use in structural situations at temperatures above 60°C is not recommended. Consult our technical team on 0113 2455450 (option 2) or send a message to [email protected] for further advice.

Tecgrip V Resin and Solvent are flammable. Should fire occur extinguish with CO2 or foam.

Grout Volumes Required

The following table gives typical Tecgrip V grout volumes required for given bolt/bar and hole diameters. The volumes given are in cm3 per 100mm of bond length.
