Recycled Aggregate
By utilising the latest crushing and screening technology, we produce a range of fit for purpose concrete aggregates. From uniformly graded coarse aggregate through to a variety of suitable aggregates, to meet national concrete aggregate specifications and when required can be tailor-made to customer requirement. Our recycled crushed concrete is excellent, and sub graded in the process. These aggregates can be used as a replacement for driveway and parking lot stone. It is commonly used as a base layer, used in metal roads, roads sub-base. It also can be used as aggregate in new concrete, particularly the coarse portion with some considerations on absorption, drying,
shrinkage, and creep.

GAP65 – Recycled Crushed Concrete
By using the latest Crusher and Screening technology, Central Environmental produces high quality graded GAP65 Recycled Crushed Concrete aggregate, that conforms to New Zealand aggregate standard and can be tailored to customer requirements. Periodic IANZ Lab tested aggregates clearly specify the particle density, particle shape, composition and grading, to suit project specifications and customer needs.

GAP20 – Recycled Crushed Concrete
20mm Recycled Crushed Concrete is passed through a 20mm screen and is IANZ Lab tested. GAP20 RCC Aggregate is commonly used for driveways, pathways, as a base course for concrete and paving. Once compacted, it binds very well with the fines.

GAP40
GAP 40 metal is most commonly used as a base under metal driveways, under paving, or as a base layer under concrete. GAP 40 is a robust, general-purpose quarry aggregate. It is open-graded and has a high permeability rate. Conversely, it requires an increased compaction effort in the process of construction.
Topsoil/Compost Blend
Topsoil is a mixture of sand, silt, clay and broken-down organic matter, called humus. Humus is rich, highly decomposed organic matter mostly made from dead plants, crunched-up leaves, dead insects and twigs. Topsoil is not weed-free as a general rule, as it has not been treated to remove weed seeds.

Screened Topsoil
Our Screened Topsoil is processed to remove debris, rocks, and clumps, making it ideal for landscaping, gardening, turf preparation, lawns, garden beds, and commercial projects.

Un-screened Topsoil
Unscreened Topsoil is a natural, cost-effective option that retains organic matter, small rocks, and natural materials. Ideal for filling, leveling, site preparation, and large-scale land improvement projects.

Compost
Compost is a crumbly, dark dirt so rich in nutrients that it’s used as mulch, fertilizer, or soil amendment but rarely to grow plants directly. Compost can be made from garden trimmings, and other organic waste by letting beneficial bacteria decompose everything to its essential elements.

Woodchips
A mulched bark chip that gives a natural look, suitable for mulching any garden are while suppressing weeds
