About the ProBASE QuickJACK Adjustable Shed Base Kit 3 for Soft Surfaces

The ProBASE QuickJACK Adjustable Shed Base System for Soft Surfaces Kit 3 puts a big shed on grass without a slab. It is made in the UK. It fits 8x7, 8x8, 9x9, 10x4, 10x6, 10x7, 10x8 and 10x10 foot sheds. The ground does not have to be flat.

There are nine screw piles with 8 inch bearing plates. A cross plate ties the middle of the frame together. Corner brackets and T brackets hold your timber. Plates adjust by up to 150mm so the frame ends up level.

Everything is 4mm thick steel with a zinc plating. With the shed lifted off the soil air reaches the floor. That keeps timbers dry and rot-free. You can also use the kit to anchor the shed against wind.

The box holds 4 corner brackets, 4 T brackets, 1 cross plate, 9 bearing plates with screw piles and 20 screws. Make the wooden frame yourself from 2 inch wide timber. A 10 year guarantee comes with it. The supplier does not offer fitting.

What It Is Made From

All parts are 4mm thick steel with a bright zinc plating. The plating guards against rust in damp ground. The steel carries the weight of a large loaded shed.

Which Sheds It Suits

Suits large sheds from 8x7 up to 10x10 feet. Check your floor size against the Kit 3 list.

Good to Know

Nine screw piles carry the frame and spread weight over a wide area. Each has a plate of 8 inches that adjusts up to 150mm. Corner and T brackets join the timber to the piles. The cross plate links the centre. Zinc-plated 4mm steel slows rust. The result is a level raised base without any concrete.

Laying the Base

Check for buried pipes and cables before you drive screw piles. Wear gloves and strong boots. Large frames are heavy so use two or more people. Level the frame in both directions. Tighten every bracket fully before building the shed on top.
