Hi there,
Hope you all had a good weekend. I am currently building a second house with the same builder when I built my first house.
My first house had soil test P / H2 (due to infill). They 'forced' me to use a P class slab.
The house I am building has a soil test the same P / H2 (due to infill), now they force me to use only a H2 slab.
I found the pre-site officer was a bit weird- she claimed that the current house (based on the engineering plan) is a P class slab but I couldnt find any references that states so - other than the soil test classification as P class.
however I found differences.
1. Slab overall depth - 385mm (second house) vs 400mm (First house)
2. Slab thickness - 85mm (second house) vs 100mm (First house).
3. Re-entrant corners - 3-N12 2000mm long (second house) vs 2-N16 2000mm long (first house)
Questions
1. What other main technical differences between the H2 and P class slabs? -
2. If everything else stays in the H2 slab "configuration" and I request to thicken the slab from 85mm to 100mm and overall dept from 385mm to 400mm, would that be a waste of Money? or its worth the shot? - would this be considered as a P class slab then ?
Thanks,
Joe
