I need some help, as I want to do my garden shed foundations. It will be a large area 20ft by 10ft and I need this raised by 3inches.
As you can image this can be quite expensive to do with concrete, I wanted to know if there were other cheaper options available.
A friend suggested that I use gravel for the footings and gain the height I need from this, following by a wet mix of cement, on top. Iâ€™m not to sure about this hence asking the question,
Thanks in advance for all your help
