Topsport Olisett 0/6 mm Hard Porous Surfacing (Black)
Standard product features
Particle size distribution:
The foundation should be 150 mm thick, constructed to accurate levels and brought to the required elevation using a well-consolidated porous crushed rock. A suitable material for this purpose would be a granular subbase or 40 mm crusher run compacted to form a smooth surface on which to lay the Olisett.
The Olisett surface should be spread on top of the foundation either by machine or by hand in one course to a depth of approximately 50 mm to give compacted depth of 40 mm. If laid by hand, best results are achieved by using accurately fixed screeds and a straight edge.
