tufftop High Performance Jointing Mortar

High-performance jointing mortar for bound (rigid) construction pavements formed in natural stone or concrete paving elements. Formulated for use in modular pavements subjected to pedestrian through to high categories of trafficking. Supplied as a pre-mixed dry product packed in moisture-resistant bags. Applied as a free-flowing slurry grout.

Features and benefits:

  • Complies with (or exceeds) the performance requirements of British Standards BS 7533-7 and BS 7533-10 for modular paving.
  • Suitable for use with all types of natural stone and concrete element modular paving up to 'Site Category 1A' and 'Traffic Category 9' applications.
  • Self-compacting characteristics allow the mortar to penetrate even the most irregular cavities and joints down to 3 mm in width.
  • Non-staining, polymer and resin free formula.
  • The elastic modulus is optimized to continually absorb thermal and dynamic stresses inherent during the life of a modular pavement, resulting in high durability.
  • Declaration of Performance EN 13813: 2002, CT C45 F6 B1.5 A15.
