Fill Sand

Fill Sand is a natural construction aggregate supplied by Kolbang Services, based in Perth, Western Australia. The product is classified as medium‑fineness fill sand with a yellow to white colour, and it originates from sea sand deposits in Western Australia. The supplier states that the sand complies with Australian Standards and is tested in a NATA‑accredited laboratory. Packaging is delivered in bulk, with shipments dispatched from the Port of Geraldton in Western Australia.

In the construction industry, fill sand of this grade typically has a particle size distribution that meets the requirements for backfilling and sub‑base layers. Standard specifications call for a bulk density of around 1.6 t/m³ and a moisture content below 0.5 % to ensure stability. The colour range of yellow/white is common for sea‑derived sand, and the medium fineness provides good compaction properties. Kolbang Services highlights that each batch is tested for compliance, although specific test reports must be requested.

Primary buyers include civil engineering firms, major contractors, local government bodies and residential builders who need reliable backfill material. The supplier offers FOB pricing between USD 50 and 100 per metric ton and accepts a minimum order of 10,000 metric tons, making it suitable for large‑scale projects. Trade terms can be negotiated, and potential importers should confirm Incoterms, payment schedules and any required certifications before finalising the purchase.
