Decking and Greenhouse Bases

Choose WoodBlocX to create a solid and attractive surround for your garden deck or greenhouse. 

When creating a deck or greenhouse base there are a number of factors that must be considered. Will your deck be in a shaded or sunny location? What size does the deck need to be? Is the site level?  Like most things planning is essential when it comes to creating an attractive and stable structure.

At WoodBlocX we are here to help with every stage of the planning and development of your decking or greenhouse base.  Firstly, it is essential to plan your deck properly. Be as accurate as possible with measurements and bear in mind that it is the deck boarding that basically dictates the size of the overall deck. Designing a deck precisely will limit cutting, and board or bearer wastage. WoodBlocX are made to measure so no wastage will occur when using them as everything you require from us will be pre-cut and drilled to make the building processes as easy as possible.  


Decking bases built in shaded areas can be greatly affected by damp and algae growth, so be prepared to treat and clean these once a year to preserve the decking. Try to avoid wet areas altogether. WoodBlocX is pressure treated with Wolmanit CX-10, a water based preservative which fixes in the cells of the timber when it dries. The wood is dried in a vacuum and then pressurised to 300 psi. If you cut a piece of WoodBlocX in half you will find that the preservative has penetrated virtually 100% of the wood. This means that WoodBlocX will last for 15 years and possibly longer, when installed following our guidelines. Ensuring the ground is level and dry will help extend the deck’s life.  

Our free design service is here to help when it come to your overall design.  Due to the huge versatility of WoodBlocX we can make decking bases to fit almost any garden area.  No size is too big or too small.  


We always suggest to construct the internal frame of your WoodBlocX decking base with treated joists and joist hangers.  The internal supports can be constructed using our BlocX but as they are not ever seen it is a more expensive option and it is usually easier and quicker to use joists.  We do not supply joist or joist hangers so these would need to be sourced separately.   

If you are interested in creating a decking or greenhouse support and would like further information or help with the design process please give us a call on 0800 389 1420 or alternatively send us an email to [email protected]
