Raised Beds Prototype From grp / plastic Composite Door Panel off cuts with Handbridge Allotment
The aim is to replace the rotting wood frame with composite door offcuts, that are glued and screwed together . These will not rot or be eaten by insects for an estimated 25 yrs +
They may be more visible, being white on one side.
So they may reduce tripping hazards in poor evening light, as many allotments / gardens are unlit
DES Pegs will be hammered into gound to support them
size is approx 2.44 x 1.22 m2 Frames are approx 30cm tall
Window cut outs are framed with door edge strips (DES) with a door edge strip section between panels horizontally to screw DES to.
They are glued together with Everbuild lumberjack 5 min PU glue & 75mm screws
A 2nd idea is to use the smaller DES screwed & glued together with cheaper silicon sealant
This is quicker to make, than it appears at first. The planks are also heavier & stronger with the grp side resisting the outward soil force
Edit: 20th September
Finished 2.4m long beam made from the thinner door edge strips (thicker strips are kept for more structural uses
They are screwed and sealed with silicone sealant . coloured side would be sited inside to be hidden by soil . so outside is white .
Wood could be screwed to the top. Wood being above the soil, would mean it lasted longer, as not in contact with wet soil
