tuffbond High Performance Bonding and Priming Mortar
Application

Suitable for use in bound construction modular pavements.

Description

A high-performance bonding and priming mortar, formulated for use in bound construction modular pavements.

Features and benefits:

  • A 1–2 mm thick coat of tuffbond, applied in accordance with the manufacturer's method statement, creates an enhanced adhesion bond of 2 N/mm² between bedding mortar and natural stone or concrete paving elements (flags, slabs, bocks or setts).
  • Enhances the adhesion between bedding mortar and supporting concrete structures/ concrete road base, resulting in a durable pavement with high resistance to mechanical sheer forces and thermal stresses.
  • Completely polymer and resin free.

To achieve full compliance with BS 7533-7 and -10 for traffic category 5–9, modular pavement construction (heavily trafficked), tuffbond is a fundamental requirement and is intended for use in conjunction with tuffbed or tuffbed 2- Pack and tufftop Jointing Mortar. Consult manufacturer for further details.

Application:

Suitable for use in bound construction modular pavements.
