MasterRoc SRS 720

Two-component, fast-reacting, spray-applied resin for high-resistance surface support

​How does MasterRoc SRS 720 work?

MasterRoc SRS 720 is a fast-reacting, two-component resin designed to enhance stability and protect against weathering across a wide range of surfaces. The components are mixed and applied as a thin paste, hardening within minutes to provide high tensile and bond strength. With excellent adhesion to most substrates, the product significantly improves ground stability and stand-up time.

Recommended uses:

• Stabilization of excavation faces and surrounding rock after blasting or cutting

• Rock reinforcement in hard-to-access areas

• Alternative to mesh/screen protection, with or without bolts

• Preliminary surface protection before final construction

• Mitigation of strain bursting and large deformations in hard rock

• Protection against air-slacking and rock weathering

• Pillar/rib support

• Rehabilitation of damaged or unstable areas

• Masonry and brick line refurbishment

• Vent-stopping applications

What are the unique features of MasterRoc SRS 720?

• Fire-resistant

• Fast setting and rapid strength development (< 5 minutes)

• Strong adhesion to a variety of substrates (rock, coal, concrete, steel, etc.)

• Water-resistant – prevents expansion or degradation upon water contact

• Easy to mix even at low temperatures (> 40 °F (5 °C))

• Ready-to-use for simple and efficient application

What are the benefits of MasterRoc SRS 720?

• Enhances structural stability and safety

• Increases service life of treated surfaces

• Reduces material waste with precise application

• Improves efficiency in tunneling, mining, and rock stabilization
