Every greenhouse, no matter how big or small, should be fastened down to a solid foundation of some sort to prevent weather damage, warping and uneven stress.
Should you require advice regarding a base please contact us for general advice or details of local contractors in your area who could help. We enclose pros and cons for different base contrustions.
Another good money-saving option is using either edging kerb-style slabs, breeze blocks, bricks or concrete to create a solid foundation only directly under the greenhouse frame, leaving the central floor portion free. You can either build up a foundation from ground level, or cut a suitable trench and fill this in with your chosen medium.
Offers just as strong a foundation as a fully slabbed base
Cost effective because less materials are used
Lots of options inside the greenhouse, either growing from ground, gravelling or a central pathway
Simple to prepare
Can be more decorative than other options
Measurements are crucial to get right because there is less room for error.
Slabs or Paving
Our preferred method if you are happy to grow from growbags, a slabbed base will last as a
solid and suitable foundation for years to come.
A clean and simple environment for your greenhouse
Can fasten your greenhouse using screws and rawl plugs for better strength in windy conditions
Better natural drainage than concrete because of the cracks in the slab joins straightforward to get level and flat
Provided they are bedded well, they will not move and warp over time meaning your greenhouse won't suffer under any strain.
More expensive than simpler options
Restricted to growing from grow bags and pots
Another potential hard-standing option, a solid concrete pad can be a good option for larger buildings.
A generous concrete pad will last for a long time
Can use expansion bolts for larger buildings to increase strength
Can be quite expensive
Standing water can be an issue unless you think about putting drains or drainage holes in
