Spec supply

Soil, to the letter of the spec.

When the drawings name a standard, the soil needs paperwork to match. AS4419 landscape soil, VicRoads VR720 topsoil, VSBA school profiles, Melbourne Water soils and engineered structural blends, batch tested with documentation on every order.

Built for the buyer with a spec sheet

Specification soil is where landscaping meets engineering. School, council, authority and designed-landscape projects increasingly call up soil by standard, not by name, and the sign-off depends on the test documentation arriving with the product.

That is how we supply it: the soil and its paperwork together, so the superintendent's question is already answered when the load hits the ground. It is the same discipline we bring to the Inland Rail landscaping works, a 40,000 m³ scope where a late or undocumented load is not an option.

Good to know

Common questions

What counts as a specified soil?
Any soil your drawings call up by a standard or specification rather than a product name: AS 4419 landscape soil, VicRoads Section 720 topsoil, VSBA school-ground profiles, Melbourne Water aquatic and terrestrial soils, or an engineered structural blend. The spec means the soil is batch tested against known limits and delivered with documentation.
Do you supply the test documentation?
Yes. Batch test documentation accompanies every specified soil order, which is what schools, councils and superintendents need for sign-off.
Can you supply specified soils at project volumes?
Yes. NXT Quarry is the inbound supplier for the landscaping works on Inland Rail's Victorian section, a 40,000 cubic metre scope that includes AS4419 soil and VicRoads specification mulch, delivered to program.
