Floor Preparation & Concrete Grinding
A premium finish requires a flawless foundation. We run heavy three-phase planetary grinders to remove old coatings, level uneven slabs, and engineer the perfect profile for your next floor.
Why 90% of Floor Failures Start with Bad Prep.
Most flooring failures, peeling epoxy, popping tiles, or shifting timber, happen because volume contractors rush the preparation. They use lightweight single-head grinders or just scrape the surface, leaving old glues and a weak concrete layer behind.
We don’t do lightweight prep.
We treat floor preparation as a structural requirement, using heavy machinery to mechanically cut deep, remove all contaminants, and expose the true strength of the slab.
The Commoner Collective Standard
Zero shortcuts. Here is how we engineer a perfectly prepped slab ready for any high-end architectural or industrial finish.
Heavy Coating Removal
We aggressively cut through old epoxies, paints, tile beddings, and stubborn vinyl glues, stripping the floor back to clean, bare concrete.
Concrete Leveling & Grinding
Fixing rain-damaged, humped, or uneven slabs. We grind the concrete flat to strict tolerances, essential for laying large-format tiles or premium timber.
Crack Repair & Chasing
We don't just patch over cracks. We chase them out with a diamond blade and inject high-strength structural epoxy binders to stabilise the slab.
Surface Profiling
Opening the concrete pores to the exact Concrete Surface Profile (CSP) required by your coating manufacturer, guaranteeing a zero-peel chemical bond.
Commercial Make-Goods & Defit Grinding
When a commercial lease ends or a new fitout begins, the slab needs to be completely reset. We handle large-scale commercial floor preparation, running heavy three-phase grinders and industrial dust extractors to strip the floor back fast and efficiently.
Suits: Retail defits, warehouse handovers, commercial kitchens, and large-scale industrial facility upgrades.
Thick carpet glues and waterproofing membranes will destroy standard grinders. We use specialised polycrystalline diamond (PCD) tooling to rip through the toughest elastomeric coatings without smearing them across the slab.
If a commercial slab gets rained on during the pour, the top layer becomes weak and dusty. We mechanically grind off the fragile laitance layer, exposing the hard, structurally sound concrete underneath so your build can continue.
Residential Floor Leveling
Laying premium engineered timber or large-format architectural tiles requires a perfectly flat slab. If the concrete is wavy or uneven, the new floor will fail. We grind residential slabs to zero-tolerance flatness, ensuring your high-end finishes sit perfectly.
Suits: Architectural home builds, major residential renovations, and preparation for timber, tile, or carpet installers.
Removing old, failing floor levelers or sand-and-cement screeds from bathrooms and living areas to drop the floor height back down to the original structural slab.
Grinding concrete indoors creates massive amounts of hazardous silica dust. We run our grinders directly attached to premium HEPA dust extractors, ensuring your home remains clean and safe during the entire prep process.

FAQ
Common Questions About Floor Preparation
No. We use heavy-duty HEPA dust extraction vacuums connected directly to our grinders. It captures 99% of the airborne silica dust at the source, keeping your property clean.
Do not waste your time scraping it. We use aggressive PCD diamond tooling that easily rips through thick tile adhesives, epoxy membranes, and carpet glues in a fraction of the time.
Yes. We map out the high spots and run heavy planetary grinders over the slab to bring it down to a zero-tolerance level, which is strictly required before laying timber floors or large tiles.
