For the self-levelling correction of uneven floors, with extra-rapid setting and drying and compensated shrinkage. For use in domestic, commercial and industrial applications and on heat-radiant slabs.


A certified, extra-rapid hardening, eco-friendly, self-levelling mineral product for the high-performance, high-thickness correction of irregular substrates, suitable for use with EMICODE® Green Building. It has low CO2 emissions, very low volatile organic compound emissions and is recyclable as an inert material.

Keratech® Eco R30 develops a high degree of workability guaranteeing a suitable surface for the subsequent laying of ceramic tiles and natural stone using eco-friendly mineral adhesives.

Features and benefits:

  • Suitable for internal use.
  • Thickness of 3–30 mm.
  • Long self-levelling time, also suitable for large surface areas.
  • Easy to apply also with continuous mixes.
  • HDE technology included, with extended flow.
  • Suitable for laying ceramic tiles, porcelain tiles, natural stone, hardwood floors and resilient materials using adhesives.
  • High dimensional stability and long-lasting performance.
  • EMICODE® Green Building rating: Eco 4.
  • CE marked to BS EN 13813, contributes to LEED points.
