Raised Beds Frame Prototype From grp / plastic Composite Door Panel off cuts with Handbridge Allotment


 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




Prototype 1

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 


Close up


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

Plan to make a low cost hardware kit to allow low income groups to build locally sourced (preferably reused) panels to make foldable shelters like Hexayurts, or for childrens play dens, animals pens or room dividers to reduce heating costs and noise
