HE Grout is ideal for a wide variety of applications:
- Precision Grouting : Machinery bases, compressors, punch presses, generators
- Structural Grouting : Steel columns, precast columns, crane rails, beams
- Anchoring : Guard rails, sign posts, dowels, rods, bolts
- Pumping Applications : Excellent flowability.
- Applicatons
Surface Preparation:
All surfaces in contact with HE Grout shall be free of dirt, oil, grease, laitance and other contaminants that may act as bondbreakers. All unsound concrete should be removed to ensure a good bond. Smooth, dense surfaces need to be mechanically abraded to provide necessary bonding requirements. Mechanically prepare the substrate to a minimum CSP 5 following ICRI Guideline 310.2R to allow proper bonding. ACI recommends that the area to be grouted should be saturated for 24 hours before placement. Remove any standing water. Substrate should be saturated, surface dry (SSD). Maintain contact areas between 40°F (4°C) and 90°F (32°C) prior to grouting and during initial curing period.
Application Thickness:
1-3” Neat, up to 8” extended.
Coverage/Yield:
50 lbs (22.7 kg) will fill approximately 0.43 ft³ (0.012 m³) when 4.0 quarts mixing water is used.
Foaming:
Method of forming must provide for rapid, continuous grout placement. For pourable grout, construct forms to retain grout without leakage. Forms should be coated with US SPEC form release for easy removal.
Mixing:
For larger batches, use a mortar mixer with rotating blades. For smaller batches, use a heavy duty 1/2” (15 mm) (or larger) low-speed, corded drill and mixing paddle #6 per ICRI Technical Guideline 320.5. Pre-wet mixer and empty excess water. Place 3/4 of the required cool, clean potable water in mixer, then add dry material. Mix on low RPM for a total of 3 to 5 minutes, adding the remaining water, until a homogeneous mixture is achieved. When using a mortar mixer higher RPMs may be necessary to achieve a homogeneous mixture. Mix only enough grout that can be placed within working time. Mix using 4.0 quarts of water per 50 lbs (22.7 kg) of dry material. Recommended flow is 125%–145% when tested in accordance with ASTM C1437 per ASTM C1107, Section 3.2.1. For placements greater than 3” depth, HE Grout must be extended 30% by weight of powder, with clean, washed and dried 3/8” (1 cm) pea gravel. Do not blend excess water as this will cause bleeding and segregation. Do not use any other admixtures or additives.
Placing:
Grout should be placed using established procedures according to American Concrete Institute recommendations. HE Grout can be placed by pumping, pouring, rodding or strapping. Mechanical vibration may cause segregation of aggregates. Place grout on one side of area. Let grout flow to opposite and adjacent sides to avoid entrapment of air and uneven bearing of the grouted surface. When necessary, provide vent holes. Grout should continue to be placed until it protrudes from the entire perimeter area. Grout “head” and excess grout may be removed after initial set. Recommended minimum placement depth is one inch.
Finishing & Curing:
Follow standard ACI curing practices. Do not disturb formwork or grout for 24 hours. Use wet rags or burlap to cure for 6 hours after placement. After 6 hours, remove rags from exposed surfaces and cure with a membrane forming curing compound such as US SPEC Maxcure Resin Clear, US SPEC Hydrasheen or US SPEC CS-25-1315. For best results, exposed grout should extend downward at a 45° angle from edge of base.
Properties
- Physical Properties
All physical property testing performed in laboratory conditions of 73.5 ± 3.5°F (23 ± 2°C) and a relative humidity no less than 50% unless otherwise determined by the test method or specification. All results represent HE Grout with 4.0 quarts water unless listed otherwise. Tests are conducted under standardized conditions for comparative purposes, and results may not be representative of performance under field conditions.

Regulatory & Compliance
- Standards
HE Grout meets and exceeds the requirements of ASTM C1107 and Corp of Engineers CRD C621. When tested in accordance with ASTM C827 at a flowable consistency per ASTM C1107, HE Grout yields a controlled, positive expansion.
Technical Details & Test Data
- Limitations
Do not apply when the surface or ambient temperature is below 40°F (4°C) or expected to fall below 40°F (4°C) within 48 hours. When grouting at minimum temperatures, ensure surfaces in contact with grout do not fall below 40°F (4°C) until final set has been achieved and grout has reached 3,000 psi. Do not apply over surfaces that are frozen or contain frost. Do not apply over any active faults or cracks in the substrate without addressing any movement that may occur. Do not use as a patching or overlay mortar or in unconfined areas. Setting time will speed up in hot weather and slow in cold weather.
