Type 1 roadstone is used as the sub-base which covers the entire area. This is a minimum of 100mm but much more in places on this project.
20mm Shock pad is then installed in all of the fall area around the play equipment.
The stone is compacted ready for the next material.
Granite dust covers all of the stone as the last layer before the grass, we work off a thickness of about 20mm throughout. The granite dust is compacted and then we “screed” the entire area so that is remains smooth and the height matches perfectly with the framework.
