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 sturdy 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. We meet and/or exceed ASTM safety standards F1951 and ASTM F1292 and we are compliant with the Americans with Disabilities Act (ADA).
Pour-in-Place Rubber Surfacing Depths & Fall Heights
Our poured-in-place rubber playground surface (and for other safety surfaces) 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. In other words, how deep/thick does the poured rubber surface need to be for playgrounds?
| Fall Height | Surface Depth |
| 4 feet | 1.5 inches |
| 5 feet | 2.0 inches |
| 6 feet | 2.5 inches |
| 7 feet | 3.0 inches |
| 8 feet | 3.5 inches |
| 9 feet | 4.0 inches |
| 10 feet | 4.5 inches |
