Planning a large shed on a concrete pad? The ProBASE QuickJACK Adjustable Shed Base System for Hard Surfaces Kit 3 is the one for 8x7, 8x8, 9x9, 10x4, 10x6, 10x7, 10x8 and 10x10 foot sheds. It is made in the UK. It works on tarmac, concrete and hardcore.
The kit has nine brackets. Four sit at the corners. Five run inline along the frame. Each has a base plate you screw down. Turn the adjusting nut and each bracket lifts up to 100mm. No preparation of the ground is needed.
Brackets are bright zinc-plated 6mm steel with a locking nut and an adjusting nut. Raising the shed lets air flow under the floor. That keeps timbers dry and rot-free and the kit can anchor the building too.
You get 4 corner brackets, 5 inline brackets and 36 screws. Build the wooden frame yourself from 2 inch wide timber. It must match your shed floor. Some DIY skill is needed. There is a 10 year guarantee and no installation service.
