Concrete base on sloping Garden

Postby alig31 » Sat Mar 27, 2021 12:01 pm

Hi all,

I am wanting to put a concrete base in for a hot tub in my garden. The garden slopes from the rear to the front. If the base is circa 2.5m x 2.5m the drop is approx 30cm. The base will have to be shallow at the rear and deeper at the front as I am building decking around it.
A couple of questions surrounding it, (no pun intended). Is it ok to have a concrete approx 450mm thick at the front? Thin end, rear of the garden will be about 150mm thick. Should I use rebar to strengthen it?
Any suggestions in framing as I will have a flat area where I have dug down, going into a slope.

Let me know if I need to post more detail
Thanks in advance.

Hi alig31
Absolutely no need for rebar in concrete 150mm +.
Don’t understand about framing so cannot help.
