Please note - all wood used has been high pressure and vacuum treated with preservative which allows for a 15 year warranty on our composters and raised beds. Colour of wood may vary from images shown as a result of the treatment process.  Also note, you may receive your order and the timber may be wet, this can be because it has stood out in the rain during transit or it can be the timber has not dried out from the preservative treatment process. If the composter is received with the timber wet you may also notice some mould on the timber this will disappear when the timber dries and will not affect the operation or the warranty we give.This will not affect the use of the composter or raised bed, however there may be some warping and twisting of the timber as the timber dries. When timber dries out there may also be some shrinkage, however this can be mainly mitigated by ensuring all the screws are used in the installation and they are firmly secured into the timber. Our wooden products are made from UK Redwood, if the timber is wet and then dries out there is a chance the timber will warp or twist. This is a natural phenomenon which should not affect the use or operation of the product. Our guarantee does not provide any form of warranty against warping or twisting. 600 Blackdown Range Single Standard Wooden Composter Extra Module Expands any 600, 1200 or 1900 Blackdown Composter.
