Kreisel - Express Beton B-50 concrete mortar 447

High-strength, fast-setting concrete mortar, reinforced with basalt fibers. Specialized concrete for underfloor heating, on the separating layer, thermal insulation and as a floating base.

Features

• fast-setting (binding after 30 min)
• frost-resistant
• non-shrink
• very high strength
• universal

Application

• for underfloor heating, on the separating layer, thermal insulation and as a floating underlay
• for balconies and terraces
