Product overview
Microcem is a range of ultrafine, controlled-fineness Portland cements formulated for geotechnical engineering, injection grouting and other specialist industrial applications. The products are produced under an ISO 9001 quality system with strict particle-size distribution and process control to ensure consistent performance.

Key information

• Suitable applications: cement-based repair compounds, injection grouting, soil stabilisation.
• Supply formats: packed bags and bulk deliveries.
• Availability: bulk tanker distribution across Great Britain and global export.

Microcem Grades

• Microcem 550 — Fine cement combining high fineness with good early strength; suitable for cement-based adhesives, repair mortars, flowing screeds and grouts.
• Microcem 650 SR — Superfine, slower-setting cement for injection into joints, cracks and soils; suited to hot climates and where extended workability is required.
• Microcem 650 — Superfine cement (finer than 550) designed for injection grouting of joints, fissures and soils to create a watertight mass.
• Microcem 900 — Ultrafine product (finer than 650) for injection into hard rock, tight joints and very fine fissures.

Applications

• Injection grouting
• Geotechnical engineering
• Marine works
• Tunnelling and specialist formulators

Benefits

• Controlled high fineness for improved penetration
• Controlled setting characteristics
• Compatible with most admixtures
• Low bleed
• Enhanced waterproofing and penetration
• Good long-term durability
• Can be blended with standard cement where required
