Precision Sub-Floor Preparation Services
A premium floor is only as good as the sub-floor beneath it. At Floor Lab, we are leading self-leveling screed contractors in Gauteng, specializing in correcting uneven, pitted, or sloping concrete sub-floors. Our fast-flow, polymer-modified cement compounds level out gravity-assisted, dry, and cure to form a smooth surface. This preparation step is essential before laying engineered wood, luxury vinyl planks (LVP), tiles, or seamless epoxy coatings.
Installing a high-end finish over un-leveled concrete causes visual slope errors, structural hollow spots, click-system vinyl lock failures, and thin epoxy wearing. Our team eliminates these issues by diamond-grinding the base concrete, applying reactive acrylic primers, and pouring custom-engineered screed leveling compounds to achieve a level tolerance of less than 2mm variance.
Fast-Cure Floor Leveling Applications
For commercial property developers and retail fitouts, project schedules are tight. Standard screeds take weeks to dry before moisture percentages drop enough for vinyl or wood laying. Floor Lab utilizes advanced rapid-cure, fast-drying leveling compounds. These compounds are trafficable within 3–4 hours and allow final floor coverings to be installed in as little as 24–48 hours, saving days of construction downtime.
Industrial Diamond Grinding
We grind away weak laitance, paint, and contaminants to open concrete pores for adhesion.
Digital Moisture Analysis
We verify the relative humidity (RH) of sub-floors before overlaying, mitigating future adhesive failure.
