Our retaining wall blocks are available in 600 mm to 1,800 mm heights and are suitable for retaining fills up to 2.5 m, depending on site conditions and backfill type. For higher walls, we recommend tiered installation or engineering input to confirm surcharge and bearing pressure requirements.

We recommend placing units on a well-compacted concrete blinding or lean concrete base (typically 100–150 mm thick). This ensures level alignment and proper load transfer, especially under traffic or building loads.

Yes. Our SP 400 slope protection blocks are designed to protect embankments, stormwater channels, culvert outlets, and riverbanks. They support steep slope gradients up to 80° and include openings for drainage and vegetation to minimize hydrostatic pressure and soil washout.

Yes. These blocks are dry-laid and interlock naturally. They can be installed directly on compacted sub-base or geotextile lining, making them quick to deploy with minimal labour or shuttering materials.

Absolutely. Our larger precast units (e.g., RW 1550, RW 1800) are suitable for road shoulders, embankment support, and culvert headwall zones, especially in road construction or expansion projects

Yes. All retaining wall and slope protection blocks are cast with embedded lifting inserts to ensure safe handling on-site. We also provide lifting guidelines to assist foremen and equipment operators.

Yes. If your project requires non-standard inclinations, load-bearing upgrades, or custom toe designs, we can produce bespoke units based on structural drawings or engineering specs.
