ProSand delivers premium Mechanically Polished Concrete for high-end architectural new builds, residential homes, and commercial slabs across Wollongong, West Dapto, Calderwood, and the Illawarra.

True polished concrete is not a superficial clear coating or a basic grind-and-seal. It is a highly meticulous, multi-stage diamond refinement process that alters the molecular structure of your concrete slab, hardening it from within to deliver a brilliant, light-reflecting glass finish that lasts a lifetime.Slab Specifications for New Home Builders.

To achieve a flawless mirror finish on the first pass, the groundwork must be planned before the concrete is poured. If you are currently organizing quotes with your builder or concreter in the Wollongong region, ensure your slab hits these parameters:

Concrete Strength: Specify a minimum 32MPa concrete mix. Lower-grade residential mixes (20MPa or 25MPa) are too soft and can degrade or crumble under heavy mechanical diamond passes.

Curing Time: The concrete slab must cure for a full 28 days before our heavy planetary grinders can safely begin the structural refinement process.

Choose Your Exposure Level: We tailor our diamond grinding cuts to your design vision. Select from Full Exposure (heavy stone reveals), Random Exposure (salt-and-pepper look), or a sleek Burnished/Industrial Finish with no stone visible.

Our Multi-Stage Diamond Refinement ProcessOur premium 15-step mechanical refinement process transforms raw, dusty slabs into dense, hard-wearing premium architectural surfaces:

Initial Metal-Bond Grinding: We use heavy-duty, metal-bond diamond segments to cut back the raw concrete, leveling the slab and exposing your chosen aggregate level.

Chemical Densification: We flood the surface with premium liquid chemical densifiers. This chemical reacts with the free lime inside the concrete, turning a soft slab into an ultra-dense, rock-hard crystalline surface.

Resin-Bond Polishing & Grouting: We transition to fine resin-bonded diamond polishing pads while applying a specialized structural grout to fill pinholes, air pockets, and minor micro-fissures.

Mechanical Polish Finishes: We continue polishing up through the progressive grit levels (from 400 up to 1500 or 3000 grit) until the floor achieves its natural, brilliant mechanical shine. No topical sealers, no fake coatings—just pure, polished stone.

Unmatched Durabiity is virtually impossible to scratch or gouge because the concrete itself has been structurally hardened.

Hypoallergenic & Low Maintenance: It doesn’t harbor dust mites, allergens, or mold. Cleaning requires nothing more than a quick microfibre dust mop and water.
