Adhesives Technology Accu-Grout LE is a precision-formulated, low-exotherm epoxy grout built for deep pour industrial applications. This three-component, pumpable system handles thick placements — up to 22 inches — without overheating or shrinking. Because it controls heat buildup during curing, it reduces the risk of cracking or thermal stress in large-volume pours.
In addition, Accu-Grout LE delivers long working time and excellent flowability, making it ideal for hot weather or extended placements. Its high compressive strength, strong chemical resistance, and dimensional stability allow it to support both static and dynamic loads. As a result, it’s well-suited for critical baseplate grouting in power plants, chemical processing facilities, steel mills, and marine structures.
Contractors rely on Accu-Grout LE for both new equipment installation and regrouting. It performs consistently in environments where strength, precision, and thermal control are essential.

Recommended Uses for Accu-Grout LE
Accu-Grout LE is the preferred choice for deep equipment baseplate grouting where elevated temperatures or thick pours would challenge conventional epoxy systems. Its thermal stability and extended set time make it especially effective for large machines, wind turbine bases, marine equipment mounts, and dynamic load applications.
Ideal for:
- Heavy machine installations with thick grout beds
- Equipment settings in warm or variable temperature conditions
- Environments requiring extended placement time
- Onshore and offshore wind turbine bases
- Marine, refinery, and chemical process industries
Frequently Asked Questions
What is the maximum pour depth?
Accu-Grout LE supports deep pours up to 22 inches in a single lift without risk of thermal cracking.
How long is the working time at 75°F (24°C)?
At 75°F, you get approximately 4 hours of working time. Full cure typically occurs within 56 hours.
Can I use it in hot climates?
Yes. Its low-exotherm formula and long pot life help prevent premature curing in warm conditions.
What compressive strength does it reach at full cure?
At 75°F, it reaches a compressive strength of 12,500 psi (86.2 MPa).
Is this grout pumpable for long-distance placements?
Absolutely. Accu-Grout LE is designed for pumpability, allowing for efficient placement over long distances.
What’s the correct mixing procedure?
First, use a low-speed drill and a Jiffy Mixer paddle. Mix Part B into Part A for three minutes. Then slowly add Part C and continue mixing until the aggregate is fully wetted out. Avoid overmixing or introducing air.
