Hi All,
First time on the Screwfix Community forum, although I have read lots of posts via google searches. My Question, I am looking to build some decking in my garden, being a confident carpenter I have no problems building the actual decking structure, however, I am struggling to find a definitive answer to how deep I should dig my footings. I am intending on using concrete poured into cardboard tube footings with a 200mm diameter spaced 2.3 meters apart. The main area of the decking will be approx 7 meters x 5 meters with a couple of walkways coming off it. I live in zone two London, so the soil is a clay type which I have heard requires deeper footings. There will be no real weight on the decking except for a seating area and maybe the occasionally BBQ with guests. Any thoughts welcome, thank you.
