tuffgrit is a crushed rock aggregate suitable for bedding paving elements where unbound (flexible, mortar-free) construction is used.
tuffgrit is an economical choice for unbound construction, affording longer maintenance intervals and heavier trafficking compared with pavior sand.
- Easy to apply, requires no mixing
- Economical, long-lasting
- High compressive strength, suitable for heavy trafficking
- Suitable for all types of unbound paving: setts, slabs and flags
- Water permeable, allows escape of water and prevents pressure build-up
It is made of igneous rock, crushed and graded to achieve optimum particle interlock for long-term stability.
Heavy Wacker plate compaction of paving elements onto tuffgrit bedding is followed by jointing using tuffsand high performance stabilised jointing sand.
