Description

tuffbond is a bonding (priming) mortar used in bound pavement construction. It is composed of a blend of cementitious binder and fine aggregate. tuffbond is used in bound surface pavement construction to provide a permanent adhesion bond strength of =2.0 MPa; between the base and the bedding mortar and between the paving units and the bedding mortar when measured in accordance with BS EN 13892-8 after 28 days. It is brush applied as a 2-3 mm thick coat having the consistency of a thick creamy liquid slurry.

Benefits

• Creates the essential adhesion bond between bedding and the paving element
• Applied to supporting concrete structures
• High resistance to shear forces and thermal stresses
• Polymer and resin free
• Provides full BS 7533-101 compliance in conjunction with tuffbed or tuffbed 2- Pack and tufftop jointing mortar
