Why are grass grids and gravel grids the ideal base for playground safety mats and terrace slabs?
Recycled plastic grass grids and gravel grid panels offer a cost-effective alternative to the traditional crushed stone base for playground safety mats or rubber granulate terrace slabs:
- In many cases, an extra crushed stone layer can be omitted.
- Earthworks are significantly reduced with much less excavation required.
- Mechanical compaction is often unnecessary.
- A slope and drainage system are generally not needed because the entire surface is permeable.
- Safety mats or terrace slabs lie more evenly and without the risk of depression formation.
- The overall structure is more economical.
The optimal construction of the support layer always depends on local conditions. When using grass or gravel grids, three installation options are available:
A: Installation directly on the existing ground
B: Installation on split (gravel) only, without an additional crushed stone layer
C: Installation on a crushed stone sub-base with a gravel topping
