Large sheds and workshops need a wide base. The ProBASE 9x9 Plastic Shed Base Kit is the 9' x 9' size in the ProBASE range. You get 36 interlocking grid squares of 500 x 500 x 40mm. It replaces a poured or slabbed base with a clip-together job.
Together the squares make a 3m by 3m square. Rain drains through it. Air passes under the floor of the shed. Pea gravel in the grids adds strength. The maker recommends 15kg per square. For 36 squares that is about 540kg of gravel. It is not included so order it with the kit.
A heavy-duty commercial weed membrane is in the pack. Roll it out before the grids. Weed growth is blocked from below. The plastic is recycled throughout. Even at this size the grids are light enough that two people can carry plenty at once.
Pair it with a big storage shed or a garden workshop of the same size. Reposition the shed later and the whole base can be reused. A 2 year guarantee applies. Full instructions come in the box.
