Factory-batched blinding concrete mixes with 20 mm aggregate, available from 15–32 MPa.
Stabilised Sand
Stabilised Sand is a controlled blend of sand, cement, and water designed to create a firm, semi-bound material that sits between loose sand and full concrete. Once mixed, it compacts into a cohesive, stable layer that holds its shape while still being easier to work and trim than concrete.
Additional Information
Additional information
The material looks like slightly damp, compacted sand with a subtle cement binder: grains remain visible, but are lightly coated and unified by cement paste, giving an overall pale sandy-grey appearance. This stabilisation significantly improves strength, stability, and resistance to washout, making it ideal for bedding and backfilling applications where consistent support is required.
Key characteristics:
- Blend of sand + cement + water, mixed to specification
- Forms a firm, stable, semi-bound layer after placement
- Pale sandy-grey colour (sand toned by cement)
- Designed for bedding, backfilling, levelling, and sub-base use
Usage
Stabilised Sand is widely used by civil contractors, plumbers, builders, and landscapers in structural and service installations:
Bedding & Pipe Support
- Used to bed and encase pipes and conduits, providing uniform support and protection.
- Reduces risk of pipe movement, deformation, or damage compared to loose sand in critical installations.
Levelling & Under-Slab/Sub-Base Layers
- Ideal as a levelling layer under slabs, tanks, and precast elements, where a firmer base is required than loose sand.
- Used as part of sub-base construction for pavements, hardstands, and structural elements (as specified by engineers).
Backfilling & Trench Stabilisation
- Applied as backfill around service trenches, pits, and structures, helping minimise settlement and erosion.
- The semi-bound nature reduces washout in wet conditions compared to plain sand.
Thermal & Utility Projects
- Used in some thermal or utility applications where a stable, consistent medium is needed around cables, ducts, or infrastructure (subject to design requirements).
Application Tips:
- Always follow the specified sand–cement ratio and moisture content provided by the designer or supplier.
- Place and compact in layers to achieve uniform density and support.
- Work and level the material before it gains too much strength—stabilised sand will firm up over time.
- Do not treat as structural concrete; for structural applications, use engineered concrete mixes as required.
