COMMENTS :- " The outcome must be important to everyone. "

- Ripping receiving surface is required in clay soil structures Cat 4,5,6. Refer to AS 1547. Always excavate & rip parallel to the site slope/AES pipe.
- Specialist soils advice & design techniques will be required for clay dominated soil having dispersive or shrink/swell behaviour. Refer AS1547
- Designers need to be familar with special requirements of Local Authorities (Minimum falls from Septic tank outlets to Land application areas etc
- Good construction techniques as per AS1547 are especially important in these soil types. Refer AS1547 & AES installation Instructions
