How I extended my patio by using unwanted brick rubble to form the base.

Patio extension

I had a load of brick rubble left over from a previous job so decided to extend my patio. As my garden slopes away, I would first have to build a block wall to retain it, then fill it with rubble and then lay patio slabs on top of that.
I first dug a trench into the lawn at a depth of 12 inches, along the length of the existing patio and two slabs width away from it. I then mixed up concrete using three parts sand, two parts gravel and one part cement. The concrete was poured into the trench and levelled off, then left overnight to set. Next day I started building the block wall to hold the hardcore. For the blockwork I used three measures of sand and one cement to give a good, strong mix. Once the wall was finished, I threw in the brick rubble and broke it up with a sledge hammer. Once it was all compressed I laid concrete over it all and flattened it out. I scored the top of the wet concrete to form a keyway with the cement under the patio slabs. Once this was all dry and set up I started laying the slabs using a spirit level to make sure they were flat. It was a great way to get rid of a pile of rubble and the extra room on the patio is really great.
