Once our underground garage is complete we need to reinstate the garden by burying it with the previously excavated soil. The SE has engineered the roof so it will carry up to 1 meter of soil over approx. 88M2 (11M x 8M). The soil coverage will be no more than 1M reducing down to 400mm.
Purely as a precaution I wanted lessen the weight by using a light-weight ground fill, I was thinking about EPS or possibly Jablite Fillmaster (just looking at Fillmaster now). I was a little concerned about the crush strength of EPS, but it should be within tolerance.
I don't need to do this at all, but it will help me sleep at night knowing I've reduced the load on the roof as much as possible.
Can anyone recommend something, ideally cheap, that can achieve our goals?
Thanks
