How many inches of fill was placed under the lawn? 3. Is the reason for making it lower to satisfy the termite barrier or the weep hole drainage issue. Personally I wouldn't have soil right up against the house like that. My first preference would be for a concrete path or similar.

We only added about 50mm of topsoil. The rest of the soil has been there since we bought the block 2 years ago. 3. Both. My understanding is that 75mm clearance is required for both termite guard and damp proof course/weepholes. The bottom of our weepholes are at the same level as the termite guard/DPC. Re: Quote for backyard Excavation - Reasonable? 8Aug 10, 2015 8:39 pm Have you protected your slab edge with a water barrier? I would be concerned having grass against the slab if it is not protected. Slab moisture can cause lots of expensive problems if left.

Can you please provide an example of what you are referring to? And is it required or just an extra optional precaution?

Slab edge protection is not critical but there is a stronger case when you have grass, soil etc against the slab. You can also apply a plastic barrier against the slab edge similar to the standard DPC.
