Microfine Injection Grout is a finely ground cementitious grout designed to fill fine cracks, narrow voids, and small openings in concrete, rock, and other suitable substrates. Its fine particle size supports penetration into areas where conventional cement grout may have limited access.
Once injected, the grout forms a stable cementitious matrix as it cures. Performance depends on factors such as substrate condition, crack geometry, water content, and injection pressure, making correct product selection and application important.
It is suitable for selected concrete repair, foundation grouting, rock and soil consolidation, tunnel construction, and seepage-control applications.
Ashtech Microfine Injection Grout is formulated for applications that require fine particle size, controlled flow, and consistent mixing. It can move through suitable cracks, pores, and voids while allowing the injection team to manage flow during application.
The grout is designed to provide controlled filling and a stable cementitious matrix after curing. Proper mixing, equipment selection, and injection pressure are essential to achieving the required performance.
Injection work often involves narrow cracks, concealed voids and difficult-to-access areas. The grout needs to penetrate these spaces while remaining manageable during pumping.
Microfine Injection Grout is designed to support this process.
Fine particles can penetrate suitable narrow openings, cracks and connected voids.
A consistent mix supports controlled movement through injection lines and into the treatment area.
The grout can fill suitable cavities and discontinuities, forming a continuous cementitious fill after curing.
Filling connected cracks and voids may help reduce pathways for water movement through treated areas.
Fine particles can help the grout reach smaller openings and connected voids.
The grout can be prepared to the required consistency, helping operators manage flow and pressure.
The material can fill suitable internal spaces and discontinuities within concrete, rock and other substrates.
Filling connected cracks and voids may reduce routes for water movement through treated areas.
After curing, the grout forms a solid cementitious matrix for suitable repair and consolidation applications.
Injection into internal voids and discontinuities can help strengthen and consolidate loose or weakened zones.
Water content, mixing time and injection conditions can affect grout flow, penetration and final performance.
Ashtech Microfine Injection Grout is manufactured under controlled conditions to support consistent batch quality. Key product properties are monitored against applicable specifications and project requirements.
At site, accurate water measurement, proper mixing, suitable equipment and controlled injection pressure are equally important.
For critical applications, review the product data sheet and project specifications before beginning the injection programme.
