- Benefits
- Extreme fluidity : Can be pumped into areas that are virtually inaccessible with standard non-shrink grouts.
- Working time : Extended for maximum pumping range.
- Strength : Attains high compressive strengths at specified water ratios.
- Thixotropic : High flow restored by agitation.
- Corrosion Protection : Encapsulates tendons, bolts or bars to protect from corrosion.
- Consistent : Strict Quality Control testing and standards.
Applications & Uses

- Applications
- Uses
RA Grout is ideal for a wide variety of applications:
- Grouting of tight clearances between precast segments, beams, columns, fissures and cracks in rocks.
- Anchor bolts, soil nails, rock and ground anchors, dowels and rods where sanded grouts restrict complete encapsulation.
- Pumping applications and maximizing anchorages.
- Application
Coverage/Yield:
50 lbs (22.7 kg) will fill approximately 0.53 ft³ (0.015 m³) when 7.75 quarts mixing water is used.
Mixing:
For larger batches, use a colloidal mixer. 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 7.75 quarts of 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 homogenous mixture is achieved. Mix only enough grout that can be placed within working time. 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. Mechanical vibration may cause segregation. When necessary, provide vent holes. RA Grout must be 100% encapsulated to prevent cracking.

Regulatory & Compliance
- Standards
RA Grout meets and exceeds the requirements of ASTM C1107 and Corp of Engineers CRD C621. When tested in accordance with ASTM C827, RA 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. Not recommended for heavy-duty precision grouting of machinery base plates or crane rails. Setting time will speed up in hot weather and slow in cold weather. Maintain contact areas between 40°F (4°C) and 90°F (32°C) prior to grouting and during initial curing period.
