Purpose & Intended Usage

Floor Purpose
Floor Flatness Class Required?FM2 / FM3 / FM4 — mainly asked for by industrial clients
ℹ FM2/FM3/FM4 is a certification spec — costs more These are defined-movement floor flatness classes (TR34/FM standard) mainly required for VNA racking or automated material handling. Meeting a stated class needs laser-guided screeding, tighter tolerance control, and a third-party flatness survey — quote this separately from standard Power Trowelled work. Confirm the exact class and racking aisle width with the client first.

Equipment, Finish & Levelling

Channel or Bullfloat (Bullmark)?Critical — determines compaction method
Vacuum Dewatered Flooring Needed?See note below
ℹ Why VDC (Vacuum Dewatering Concrete) is usually not needed here VDC mechanically pulls excess bleed water out of freshly-poured concrete to lower the w/c ratio. Power Trowelled floors rarely need it: readymix concrete trucks already deliver a mix design controlled at the batching plant, and trowelling itself works off surface water as it progresses. Worth using only for high w/c-ratio or poorly-controlled site-mixed concrete.

HOW

How We Deliver Your Floor

01
Site Preparation

Before any concrete is poured, our team inspects the site — substrate condition, power availability, access for machinery, and tool readiness. Where old concrete removal is in scope, we handle breaking and disposal separately with dedicated resources.

Pre-pour inspection Breaking: scope-dependent
02
Level Setting

We set screed rails or channel formwork to your specified slab thickness and, where required, slope. Levels are verified with laser or dumpy level before the pour begins — ensuring consistent thickness across the entire area.

Laser-verified levels Slope confirmed if specified
03
Concrete Placement & Compaction

We coordinate concrete delivery, pump positioning, and spreading to achieve a uniform pour. Our team uses internal vibration during placement to eliminate voids and ensure full consolidation — critical for long-term floor durability.

Void-free compaction Consistent pour management
04
Power Trowel — Initial Pass

Once the concrete reaches the right firmness, our operators begin the first Power Trowel pass with a pan disc. Timing is everything at this stage — our team reads the concrete and waits for the correct window, rather than rushing and compromising the finish.

05
Floor Hardener Application

We apply floor hardener in two timed passes — the first at roughly two-thirds of the dosage once bleed water disappears, the second once that layer is absorbed. This two-pass method builds maximum surface density and wear resistance.

Two-pass application Dosage per system spec
06
Final Finish

Multiple progressive Power Trowel passes bring your floor to the specified finish. Our operators work systematically across the full area to deliver a consistent result — whether Salt & Pepper or High Gloss Polished.

Salt & Pepper Polished
07
Control Joints

Where specified, we cut control joints at the correct time window after the pour. This directs any concrete shrinkage to planned lines, protecting the long-term integrity of your floor and preventing uncontrolled cracking.

Where specified Timed to concrete strength gain
08
Curing & Protection

Curing begins immediately after the final finish. We apply curing compound or wet curing covers as agreed — protecting the surface while the concrete reaches full design strength. A minimum of 7 days is standard; 28 days is recommended for optimal results. Scope as confirmed in your contract.

Scope as agreed Min 7 days · 28 days preferred
09
Site Handover

On completion, we photograph and document the finished floor before handover. Any observations from the pour are noted and communicated to you directly. We leave your site clean and the floor ready for the next phase of your project.
