GREENHOUSE BASE GRID 4M X 2M SUITS 12X6 TO 13X7 FEET GREENHOUSE & SHED BASES = FULL ECO KIT + HEAVY DUTY MEMBRANE - PLASTIC ECO PAVING SLAB BASES & DRIVEWAY GRIDS

Easy to cut and assemble. They're also quite flexible so they can cope with small changes in height and gradient. They seem very sturdy and I'm sure the will cope with a lot of load. The underlay was a welcome bonus.

I bought these to install a new shed. After building up the base (it was on a slope), I lay the supplied weed control and fitted the grid before filling with pea gravel. A 12ft x 6ft shed was then erected on the base with no issues. 3 months later it is still solid.

Used to raise the floor of new shed off damp paved area, easy to install and does the job perfectly, wish I'd done it 2 sheds ago.

Some of them where broken and damaged on corners

Had to give a 2star due to no membrane in the box so had to purchase one

Absolutely fabulous product saved time not having to slab put a large shed on it was so easy a lot of shingle to buy but well worth it would definitely recommend.

Quick delivery, value for money

Saved a lot of hard work making up a wooden base for my 12 × 6 shed...Arrived very quick and everything went down with no problems
