Aggregate Exposure & Concrete Densifiers

At FloorLab, we specialize in high-durability polished concrete. We grind concrete slabs to remove laitance, expose the underlying aggregate, and apply chemical densifiers to increase abrasion resistance by 40%. We offer four distinct aggregate exposure classes to fit your design:

A

Cream Finish (Class A)

Minimal grinding that exposes only the cement paste. Yields a smooth, solid, monochromatic look with tiny surface variations.

B

Salt & Pepper (Class B)

Light grinding to expose fine sand and tiny aggregate particles. Creates a classic, subtle textured look resembling terrazzo.

C

Medium Exposure (Class C)

Moderate grinding to expose larger stones and aggregate. Ideal for high-end showrooms and striking architectural designs.

D

Heavy Aggregate (Class D)

Deep grinding exposing maximum stone size. Offers a rugged, bold industrial-modern texture with ultimate structural strength.

Architectural Choice

Polished Concrete vs. Micro-Cement

Compare the two premium seamless finishes to select the perfect application for your project constraints.

Heavy Duty / Structural 💎

Polished Concrete

The direct grinding, densifying, and polishing of an existing structural concrete slab. Suitable for ground floors with solid concrete substrates and commercial spaces.

  • 📐 Thickness: Zero added thickness (uses existing slab)
  • 🛡️ Strength: Extremely high compressive strength (up to 50MPa)
  • 🎨 Aesthetic: Organic stone aggregate exposure and gloss reflection
  • 💧 Moisture: Breathable, handles typical vapor transmission

Versatile / Thin Overlay 🎨

Micro-Cement Overlays

A thin, polymer-modified cementitious overlay troweled by hand. Can be applied over timber, old tiles, screed, or drywall, on both floors and walls.

  • 📐 Thickness: 2.0mm - 3.0mm total thickness
  • 🚿 Wet Rooms: 100% waterproof, grout-free (ideal for showers)
  • 🎨 Aesthetic: Smooth hand-troweled plaster look, custom tinted colors
  • 🏗️ Weight: Lightweight, no structural load implications

Substrate Preparation

SANS 10070 Flatness & Sub-floor Standards

Concrete overlays and polished floors require flat bases. In compliance with the SANS 10070 code of practice, we verify that concrete sub-floors have a level tolerance of under 2mm over 3 meters. High spots are ground down with planetary grinders, and structural cracks are stitched with high-strength epoxy.

We test all concrete bases digitally to guarantee relative humidity is within the safe thresholds before laying overlays.
