Installation Instruction for Pavable Tree Grates
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.
Attention:
A traversability of up to 50 kN can only be guaranteed if the system is installed correctly.
2) Place Support Frame on Concrete foundation
Place the two-part support frame on the concrete foundation and bolt it to the foundation using the following means:
• 4 hexagon wood screw M12
• 8 washer
• 4 nylon dowels
(fastening set not included in the scope of delivery)
3) Screw Support Frame Together
Screw the two-part support frame together using the following means:
• 2 hexagon head screw M8x25
• 2 washer

4) Place the Beam in the Frame
Place the beams in the frame. The recess in the tabs welded on at the bottom marks the position for the inner frame.
