tuffgrit - Bedding aggregate (TR)

A crushed igneous rock aggregate suitable for use as the laying course material for conventional unbound modular pavements and as the laying course and jointing material in SuDS permeable unbound modular pavements. 

Applications include driveways, public realm, commercial areas, patios and pavements using any paving units. 

tuffgrit is blended for optimum interlock of the angular particles, actively extending the durability of unbound/flexible pavements.

Key Features 

• Water permeable (SuDS)
• 2-6 mm natural aggregate
• Available in 25kg bags or bulk bags
• Highly durable
• As described in EN 13242
• Complies with BS7533-101, Table 8, for unbound laying course bedding material up to traffic category 9 (and for bedding and jointing as described in the still current BS7533-13 guide for the design of permeable pavements)
