6 packs (24 grids) does not make a square.

BnQ website says buy 6 packs to make a 8x8ft base which will leave you 1 grid short. You then have to dismantle half of your base to borrow a grid from the centre to finish the square. Ridiculous.

Great product

Great interlocking base. Perfect for our summerhouse. Easy to fit together and fill with shingle for drainage and stability. We used the same type for our shed many years ago and that is still in great condition so it’s clearly durable.

Easy to install

I bought this product for my shed base and it was easy to clip them together and install. Good product

Easy product to assemble and use.

I bought this product to provide a base for two large 'Keter' storage boxes. After raking the ground to an acceptably level state, the interlocking base sections were very easy to connect and manoeuvre into place. They have formed a stable and level platform, smoothing out inconsistencies of the roughly raked area. The boxes have been placed on the platform and are very secure. Highly recommended.

Not very clear on the b and q site

What your website doesn’t say is you need multiple packs of these bases depending on the shed size you purchase. Only got home with it to realise I need another 4 packs

Interlocking Shed base

The interlocking shed base was great for the job intended. It is both strong and easy to use. However, I do think It is a bit over priced at £25 for 4, it should be £5 each at most in my opinion.

Excellent item

I bought these to make a step free walkway from slabs, across gravel, to tarmac. to make walking easier for my wife. Easy to lay directly on levelled gravel and filled afterwards. Looks great and easier to walk now.
