Explore Features ↓What is Rock Grout GP80?
ROCK GROUT GP-80 is a high-performance, non-shrink, free-flowing cementitious precision grout specially engineered for heavy-duty structural grouting applications. Designed for situations demanding exceptional compressive strength, it provides reliable support beneath machinery, structural steel, and reinforced concrete elements while ensuring complete load transfer without shrinkage.
Manufactured using high-quality cement, graded aggregates, and advanced expansion technology, ROCK GROUT GP-80 develops compressive strengths exceeding 80 MPa. Its free-flowing consistency allows it to penetrate deep into narrow gaps, complex cavities, and confined spaces without segregation, producing dense, void-free grouting with outstanding structural integrity.
Unlike conventional cement grouts, ROCK GROUT GP-80 undergoes controlled expansion during both plastic and hardened stages, eliminating shrinkage and maintaining continuous contact between the grout and supporting surfaces. This ensures maximum bearing area, superior load distribution, and long-term dimensional stability even under heavy static or dynamic loading conditions.
ROCK GROUT GP-80 is ideal for heavy machinery foundations, crane rails, bridge bearings, column base plates, anchor bolts, precast concrete elements, industrial equipment, turbine foundations, and structural concrete repairs where superior strength, durability, and precision grouting performance are essential.
How Rock Grout GP-65 Works
Prepare the Surface
Clean all concrete surfaces thoroughly and remove dust, grease, loose particles, and standing water before grouting.
Mix the Grout
Mix ROCK GROUT GP-80 with clean water until a smooth, free-flowing consistency is achieved.
Pour the Grout
Pour continuously from one side, allowing the grout to flow naturally beneath base plates and into cavities.
Complete Void Filling
The highly flowable grout fills intricate gaps completely while maintaining full bearing contact without segregation.
Cure & Load
Allow proper curing to achieve maximum compressive strength before placing the structure into service.
Prepare the Surface
Ensure the concrete is clean, sound, and free from dust, oil, loose particles, and standing water.
Mix the Material
Mix with clean water until a smooth, free-flowing grout suitable for precision placement is obtained.
Pour into Position
Pour continuously from one side so the grout flows beneath machinery, plates, and structural supports.
Self-Level & Fill
The grout naturally fills all voids and confined spaces while maintaining complete structural contact.
Cure & Finish
Allow sufficient curing before applying service loads for maximum long-term performance.
