Compliant Wet Pour On To New Base (15mm & 20mm)

New Base Construction (assuming reasonable draining sub-soil)

Excavate existing concrete/tarmac/grass base to a minimum of 155mm for the macadam base, or 215mm for a no fines concrete base.
Standard edge detail is to supply and install well haunced 50mm x 150mm precast concrete edgings. Alternatives available include pressure treated timber of a minimum size of 25mm x 150mm, firmly fixed with suitable pegs at 1 metre centres.
Supply and lay 100mm depth of M.O.T. Type 1 foundation stone.
Supply and lay either 40mm consolidated depth of 6mm open textured macadam or 100mm depth of no fines concrete which must be flattened with a vibrating roller to create the levelest possible porous surface. Care must be taken to ensure that a consistent 15mm or 20mm depth for COMPLIANT WET POUR remains, particularly at the edges, and that the selected material is flush right up to the kerbing. Levels should be to a tolerance under a 3 metre straight edge not greater than 10mm.
Remove all spoil material from site. Clean up, leaving site neat and tidy, reinstating where necessary.
After a suitable period for weathering and curing has elapsed the base is ready to accept our COMPLIANT WET POUR Impact Absorbing Surfacing.

New Base Construction (assuming reasonable draining sub-soil)

Excavate existing concrete/tarmac/grass base to a minimum of 100mm depth of M.O.T. Type 1, selected thickness of concrete plus minimum 15mm or 20mm depth of COMPLIANT WET POUR.
Standard edge detail is to supply and install well haunced 50mm x 150mm precast concrete edgings. Alternatives available include pressure treated timber of a minimum size of 25mm x 150mm, firmly fixed with suitable pegs at 1 metre centres.
Supply and lay 100mm depth of M.O.T. Type 1 foundation stone.
To ensure drainage through to base, the finished concrete should either be drilled through with 19mm / 25mm diameter holes at between 500mm or 1 metre centres or similar dimensioned conduit type piping can be set into the concrete to ensure that vertical drainage can be achieved. Holes should be back filled with a clean stone, aggregate or sand.
Supply and lay 75mm - 100mm depth concrete with either a lightly brushed or trowelled finish. The base should be left to suitably cure before COMPLIANT WET POUR is installed.
After a suitable curing period, if necessary, the base should be cleaned either chemically or with a power hose / pressure cleaner to remove any dirt and debris.
If necessary the base should be suitably primed to accept COMPLIANT WET POUR.
Base is now ready to accept COMPLIANT WET POUR Impact Absorbing Surfacing.
Reinstate where necessary, if and as agreed.
Remove all spoil material from site, clean up, leaving site neat and tidy.
