The Resin that Binds
Bonded Rubber Mulch is a consistent and stable surface which is also permeable, so will allow drainage and water to get to plant and tree roots.
One of the most important aspects to consider with Bonded Rubber Mulch surfaces is the installation of an appropriate subbase to ensure longevity of the surface, an even finish and adequate drainage.
Sub-bases
Our bonded rubber mulch surfaces can be laid directly onto a solid surface (e.g. tarmac, concrete).
For any installation of bonded rubber mulch onto a soil/grass area we recommend the installation of a stone sub-base is to aid longevity, provide additional water drainage, and to prevent uneven settlement of the surface.
The depth of the sub-base will vary depending on the ground conditions, be it soft clay soil, stony ground, or where there are many tree roots in situ. A minimum of 50mm depth of sub-base material, usually MOT Type 1, laid over a geotextile membrane is sufficient.
Depending on the sub-base stone type, the surface will also require a thin layer of grit sand to ensure a flat, smooth surface.
