Installation Instruction for Pavable Tree Grates

Concrete foundation for square tree grate
1) Underground Preparation / Concrete Foundation

Create a gravel or sand bed of approx. 5 cm thickness on a load-bearing substrate and lay the concrete foundation on top. Join the foundation beams with tongue and groove. The foundation must be placed below the upper edge of the covering, reduced by the height of the insertion frame (check for each order). Please make absolutely sure that the foundation is installed level and parallel to the surrounding surface.

A traversability of up to 50 kN can only be guaranteed if the system is installed correctly.
