Sub-Floor Prep: Solving Common Slab Defects

Installing floors over defective sub-floors causes warping, hollow spots, and click-lock failures. Our crew uses precision leveling compounds to address these structural concrete defects:

Slab Anomalies 🩹

Crack Stitching & Repair

We open stress cracks and anchor them with high-tensile steel pins before pouring, preventing reflective cracks from traveling up into your final floor coverings.

Flatness Defects 📐

Hollow Spot Correction

Low deflection pockets in sub-floors create hollow underfoot sounds. We verify level depths and fill low spots to provide a completely solid sub-floor base.

Slope Deviation 💎

Level Deviation Grinding

High ridges are ground down utilizing diamond grit metal disks on planetary grinders to achieve flatness tolerances compliant with the SANS 10070 code of practice.

Downtime Reduction

Rapid-Cure Floor Leveling Applications

Standard sand-and-cement screed mixes take up to 28 days to fully cure and dry out before wood or vinyl floors can be safely installed.

FloorLab utilizes advanced polymer-modified leveling compounds that dry out via chemical hydration. They are trafficable in 3–4 hours, allowing final vinyl, wood, or epoxy floor coverings to be installed in under 24 hours.

Curing Timeline Comparison

FloorLab Rapid-Cure 24 Hours
Chemical hydration drying. Safe for final overlay next day.
Standard Concrete Screed 21-28 Days
Water evaporation drying. High risk of trapped moisture warping.
Quality Standards

SANS 10070 Sub-floor Standards Checklist

Our technical teams strictly follow SANS 10070 and SANS 10186 codes of practice to verify the sub-floor is structurally stable and flat before proceeding.

✓

Moisture Control

Slabs digitally audited to guarantee moisture is under the strict 3% limit.

✓

Flatness Rating

We check levels to guarantee flatness variance is under 2mm over 3 meters.

✓

Concrete Profiling

Diamond surface grinding to strip paint/laitance and open concrete pores.

✓

Mixing Ratios

Mechanical paddle mixing using strict manufacturer ratios to prevent bubbles.

Location Coverage

Based in Gauteng, we mobilize sub-floor preparation crews across Johannesburg (Sandton, Midrand, Randburg, Roodepoort) and Pretoria (Pretoria East, Centurion).
