Keep your garden building’s walls clean and free from rot, with this set of ProBASE French drains. Perfectly designed to fit into the ProBASE grids, along two sides of your wooden garden building, they prevent rainwater splashback and the resulting build-up of soil particles on the wood.

What’s more, if you buy these ProBASE French drains through us, we’ll include a pack of ProBASE anchor blocks for FREE! These anchor blocks lock your garden building to its ProBASE, ensuring that it remains completely secure, even during high winds.

You can attach the garden building’s wooden frame to the anchor blocks with either standard screws or nuts and bolts. If using screws, drive one through the garden building’s wooden frame and each anchor block. When using nuts and bolts, you should pre drill the building’s frame and each anchor block BEFORE filling the ProBASE grids with gravel. Once done, lift up the corner of the base to position each bolt, then fill the ProBASE grids with gravel. Finally, reposition the garden building and secure it to the anchor blocks with the nuts.

Each anchor block is pull tested to 60kg. Please be advised that fixings are not supplied.

This pack contains 92 French Drain Blocks and 4 Anchor Blocks.
