The mixed grout is pumped into place using a Pumpable mortar cartridge gun. Each filling of the gun must be used within 5 minutes to avoid thickening. The product in the mixing vessel must be mixed each time a gun filling is carried out.

The injected grout will tighten in the anchor hole and fix the bolt, tie or other unit into the substrate. Tecgrip S is suitable for fixings into most construction materials including concrete, rock, brickwork, masonry blockwork or other substrates capable of carrying the design load.

Application

Substrate Quality/Pre-Treatment

Holes should be drilled with rotary percussive drills on air or water flush wherever possible. If fluted drills are used, the holes should be cleaned by wire-brushing and blown out with clean compressed air. The airline should be extended to the bottom of the hole to ensure complete removal of drilling debris and dust. Prior to application the drilled holes should be dampened with water and any excess water blown out.

Mixing

Pour 5 litres of clean water into a clean mixing vessel for each complete bag of Parex Tecgrip S. Slowly add the powder to the water whilst continually mixing. Mechanical mixing should be carried out using a high torque slow speed drill with a Grout Stirrer. Mix material for a further 2 minutes after all powder has been added to achieve a homogeneous mix.

Application

Load the mixed anchor grout into the cartridge of the injection gun. Use an extension tube for the cartridge to allow filling of the hole from the bottom to the mouth. Immediately after placing the Parex Tecgrip S, insert the bolt, bar, wall tie, slotting or other fixing. Gently agitate the inserted fixing to ensure complete contact by the anchor grout. Once placed do not disturb before the anchor grout has hardened. Each cartridge filling should be used within 5 minutes. Prior to each cartridge loading, the material in the pail should be re-mixed to maintain grout workability.

For best tensile anchorage results, a minimum embed- ment depth of 100mm is recommended. Hole diamet- ers may be varied but a minimum of 3mm all-round clearance should be used. This clearance may be in- creased for ease of placing fixings into deep holes.

Factors controlling uniaxial pull out load:

• Type and strength of substrate
• Embedment depth
• Hole preparation
• Type of fixing

Curing Treatment

Protect all exposed surfaces from premature drying. Standard curing treatments can be utilised such as damp hessian sheets, plastic sheets or suitable curing membrane such as Sika Antisol MP10.

Cleaning of Tools

Clean all tools and application equipment with water immediately after use. Hardened/cured material can only be mechanically removed.
