tuffgrit High-Performance Permeable Laying Course and Jointing Aggregate
High performance, crushed igneous rock laying course and jointing aggregate which is water permeable and frost resistant.
Application
Suitable for use as a laying course and jointing material in unbound pavements.
Description
A carefully blended, crushed igneous rock aggregate, graded and formulated for use as the laying course and jointing material in unbound pavements constructed in natural stone, pre-cast concrete setts, slabs and other modular paving elements.
Features and benefits:
- In heavy trafficking environments and where longevity is required, tuffgrit aggregate is purpose blended to generate optimum interlock of its angular particles under compaction, resulting in extended life and durability of the pavement surface.
- Compliant with the requirements of BS 7533-13: 2009, 'Guide for the design of permeable pavements', (Table A2 grading for laying and jointing material), where unbound construction methods are used.
