A1 Sheds: NEW ProBASE QuickFIT Shed Base with FRENCH DRAIN and ANCHOR BLOCK accessories – How to fit Guide

PROBASE GRIDS: STRONG plastic shed base grid foundation is designed to carry a vertical load such as a garden building without the need to fill the grids with gravel. ProBase grids are independently tested when empty at over 200 tonnes of vertical load per square metre, making it easy for the DIY novice to achieve a professional quality shed base for your garden building.

NEW* QuickFIT CLIP SYSTEM: ProBASE grids are supplied with a new and improved QuickFIT Clip system, for easier, quicker installation. They are completely reusable, maintenance-free, easy to handle, and cost a fraction of the price of a traditional concrete base. Simply click as many ProBASE grid tiles together as required to make a base foundation of ANY SIZE. If required, ProBASE tiles can be easily cut to any shape using a normal hand saw.

The walls of each side have open construction to allow better drainage. The Unique FRENCH DRAIN option is perfect for reducing rainwater splashback off the roof, whilst moving the water away from your base at the same time.

Fantastic clip-in ANCHOR BLOCKS along your shed to be fixed onto the base. This is ideal for greenhouses and metal sheds that don’t have floors, or plastic sheds that need to be fastened down.

ProBASE Grids are available at the lowest price in the UK from A1 Sheds at
