BIRSS RSM-2M M550 Moroz — R4 repair mix with anti-freeze admixture
Mix for hand repair of joints, cracks and concrete defects without formwork at low and sub-zero temperatures; at +20 °C it reaches 55 MPa in 28 days.

Stounpol binds natural stone chippings — BIRSS Granitnaya Kroshka (granite chips) — into a seamless decorative surface for car parks, parking areas, access roads with goods traffic, footpaths and pavements. The binder is colourless; a pigmented version is available by agreement. The coating stays elastic down to −20 °C and has a tensile strength of 14 MPa; the manufacturer estimates the service life of footpaths at 10–20 years.
