Compliant Wet Pour On To Existing Base (Minimum 40mm)

Existing macadam / concrete base (assuming reasonable drainage sub-base)

The existing base should be thoroughly inspected to ensure stability and long term life expectancy.
If necessary, to ensure drainage through base, it should be drilled through with minimum 18mm dia holes at between 500mm or 1 metre centres. Holes should be backfilled with a clean stone, aggregate or sand.
If necessary the base should be cleaned either chemically or with a power hose / pressure cleaner to remove dirt and debris.
If necessary the base should be suitably primed to accept our COMPLIANT WET POUR surfacing.
To ensure a firm edge detail the existing surface should be 'chased' to a minimum depth of 12mm x 60mm wide, as suggested by the Association of Play Industries (A.P.I.), although Boyd Sport & Play Ltd. would normally enlarge this wherever possible.
The edge gradient from the top of the full depth of our COMPLIANT WET POUR to edge the external edge of the COMPLIANT WET POUR, is usually no steeper that 1 in 2 for thicknesses up to 50mm and 1 in 2.5 for thicknesses over 50mm.
The area of full depth surfacing, before the edge gradient and 'chase' should be to the full required distance from the measured edge of the equipment.
The base is now ready to accept our COMPLIANT WET POUR Impact Absorbing Surfacing.
