Certified for the water authorities, WSA PS 361 fine crushed rock embedment with the paperwork to prove it.
WSA PS 361 is the Water Services Association product specification for fine crushed rock pipe embedment: manufactured from sound, non-sedimentary rock with tight grading and durability requirements. If you’re laying water or sewer assets for a Victorian authority, this is the material the spec calls up.
We supply certified PS 361, alongside PS 362 (10mm) and PS 368 (recycled sand) grades, with compliance certificates attached to every order. The digital docket trail in NXT Control means your asset handover documentation builds itself.
