Hi
Hoping to get a builders or site supervisors advice on am I better sticking to just a standard slab or going dropped edge beams. Reason is we have a slight fall and the builde ris cut and filling. On the fill side we are 1350mm away from the fence and after building need to do a retaining wall approx 11 metres long most probably to contain the fill. Have been quotes approx $1500 extra for dropped edge beams which I think will be cheaper than getting a retaining wall down however I have no idea on retaining wall cost. Are drop edge beams more prone to problems or slab cracking etc? Only reason I ask is my other house which is built in a clay ridden area has cracking on the slab and its only at the spots where the drop edge beams are. The soil wer are building the new house on is reactive also and builder is specifying a h1 class slab. Whats my best option going drop edge beams or just doing a retaining wall?
Thanks
