FasTrac HP Cement Grout is a hydraulic-cement-based, precision, non-shrink, load-bearing grout having an extended working time of up to 30 minutes under fluid conditions.  HP Grout is designed to transfer load effectively and safely, ensuring a long service time for the grouted item.  It is a non-corrosive, non-metallic, mineral-based precision grout, developed to have a high initial and ultimate flexural and compressive strength. It can be mixed quickly, as needed, on the job site. HP Grout offers exceptional workability and is easily placed by pouring or pumping. The product is designed to give a non-shrink performance under various conditions for both interior and exterior applications.

Application Instructions
All grout contact surfaces must be free of oil, grease, scale, penetrating sealers, or all other types of contaminants that will interfere with the bond.  Mechanically roughen or high-pressure water jet the existing concrete substrate. The surface must be rough and profiled, but generally level.  The grouting area must be saturated with water 12-24 hours prior to grouting. Remove all excess water before placing grout.  The minimum application thickness is 1/2-in an extension with pea gravel is recommended for applications greater than 4-in. Finish the completed repair, as required without overworking the surface. 

The forming method must provide for rapid, continuous grout placement. For pouring, allow a minimum clearance of 3” for entry and 6” minimum grout “head”. Forming must also provide venting to avoid entrapment of air. Provide ½” minimum form clearance on all sides and 1” clearance for head.  Ensure the form is well sealed and an appropriate form release agent has been applied for that type of form.

Small quantities of HP Grout may be hand mixed in a concrete mixing pan until lump free. For large quantities and continuous pours, mix using a mortar mixer with rubber-tipped blades or appropriate grout pump for a minimum of 3 minutes or until lump-free and uniform. Use the minimum water required to produce desired placement consistency.  Use 3.1 quarts (2.9 L) of water per bag for plastic consistency; and 4.1 quarts (3.9L) for fluid. Mix in 2 steps: add 2/3 of water requirement then add grout. After partial mixing, add the remainder of water for desired consistency. Thoroughly mix the total quantity for 2-3 minutes. Do not mix more than can be placed in 15 minutes at 75°F (23°C). Do not re-temper.

Application Temperature Range
40° F to 90° F (Hot weather placement procedures recommended above 90° F; Cold weather placement procedures recommended below 50° F)
