Installation advice
Place the base module on a stable, level surface. Interlock the boards starting from the corners — no tools required. If you are fitting a riser at the same time, assemble both levels together before filling. Place a geotextile membrane at the bottom if the bed is placed on a hard surface to retain the soil while allowing water to drain through. Fill with a mixture of light soil and compost (60/40) in layers, lightly compacting between each layer.
Care and protection
Untreated Douglas fir turns grey outdoors within a few months — this greying is normal and does not affect its strength. An outdoor Douglas fir oil applied once a year (in spring) maintains the colour. The fixing-free system makes dismantling easy at the end of the season for cleaning or winter storage. Reassemble dry before putting back into service.
WoodUp Tip
Good to know before purchasing: the nail-free and screw-free assembly relies on a notch system. Check that the ground is level before assembly: any unevenness will result in visible gaps once the boards are interlocked. For the usable volume (84x84 cm over 20 cm in height, approximately 141 litres), expect between 70 and 155 kg depending on the mix (dry light compost, moist compost/soil mix or garden soil). This module is extendable with riser kits (ID 1051) for a greater growing depth.
Frequently asked questions
How many risers can be added to this base module?
A maximum of two risers are recommended, bringing the total height to 40 cm. Beyond this, the lateral pressure of the soil may cause the boards to deform.
Does the nail-free and screw-free system hold well over time?
Yes. The interlocking system is held in place by the natural pressure of the soil filling the raised bed. The more the bed is filled, the more stable the assembly. When empty, the boards can be easily disassembled — which also makes winter storage straightforward.
Is this module compatible with risers from other brands?
No. The interlocking system is specific to the Woodup nail-free and screw-free range. Use only Woodup 100x100 risers to ensure notch compatibility.
Can this raised bed be dismantled to overwinter it indoors?
Yes. Tool-free dismantling takes a few minutes. Store the boards flat in a dry place. Douglas fir withstands frost outdoors, but indoor winter storage extends the lifespan of the wood.
What minimum surface area is needed to install this raised bed?
The raised bed occupies a footprint of 100x100 cm. Allow a circulation space of at least 60 cm all around to provide easy access to all four sides during planting and harvesting.
