Surface Preparation / Base for Safety Surfaces

The prep work needed when installing any type of rubber surface is a critical part of the process. It is very important to have a study and level base to support the new play surface. Proper pitch for drainage is also key. All of our poured in place rubber and rubber tiles are completely porous, so runoff needs to occur underneath each playground. When installing new systems we recommend a minimum of a 4-6 inch compacted crushed stone base. Installations are also possible over existing concrete or asphalt.

Poured in Place Surfacing Depths

Our poured in place surface is always installed at proper depths to meet current ASTM HIC (head injury criteria) standards. Below are the required depths according to the fall heights of each play structure.

Fall Height     Surface Depth

4ft.                   1.5 inch
5ft.                   2.0 inch
6ft.                   2.5 inch
7ft.                   3.0 inch
8ft.                   3.5 inch
9ft.                   4.0 inch
10ft.                 4.5 inch
