Concrete polishing and grinding
We grind, hone, densify and polish existing structural concrete slabs across Bay Area warehouses, corridors, laboratories and campuses. Mechanical refinement turns dull, porous concrete into a dense, dust-free, light-reflecting floor without topical coatings that peel or tire under forklift and foot traffic.
What we look for
On the walk, across the concrete slab.
- Slab flatness and joint lippage
Control joints, curling slab edges and transitions exceeding one-eighth inch that require heavy metal-bond foundation grinding before honing.
- Existing coatings, adhesives and curing compounds
Old urethane, carpet mastic, VCT cutback adhesive or flaking sealers that must be mechanically ground off so the densifier can penetrate.
- Aggregate exposure and finish class
Whether you want a cream polish, a fine salt-and-pepper appearance or exposed aggregate, paired with a matte, satin or high-gloss reflection.
- Cracks, spalls and control joints
Pinholes, divots and joint edges that need grout filling or joint rebuilding before the intermediate diamond honing passes.
- Power, slurry and dust containment
Machine power requirements, HEPA dust extractors, wet slurry vacuum recovery and protection for racking, glass walls and floor drains.
- Traffic and staging windows
How aisles, corridors or bays can be phased so staff, carts and material handling keep moving without walking across active grinding zones.
Mechanical concrete refinement
From rough slab to a dense, reflective floor.
Polished concrete refines the slab already under your feet, eliminating the cost and waste of installing a separate floor covering.
Foundation grinding and leveling
Planetary grinders with coarse metal-bond diamonds remove old coatings, flatten uneven slab joints over one-eighth inch and open the concrete pores.
Grouting and chemical densification
Micro-pits and hairline voids are filled, and a penetrating silicate densifier reacts with free calcium in the slab to harden and dust-proof the surface.
Progressive diamond honing
Successive passes with medium and fine resin-bond diamonds remove grinding scratches and build a smooth, even surface across the aisle or corridor.
Polishing and stain guard protection
High-grit diamond abrasives and burnishing pads bring the concrete to a satin or high-clarity polish, finished with a breathable stain-resistant guard.
Operational advantages
Why facilities choose polished concrete.
Brighter rooms
Reflective slabs bounce overhead light across corridors and bays, improving visibility throughout the space.
Lower upkeep
No wax stripping or recoating cycles; routine dust mopping and neutral auto-scrubbing keep the floor clean.
Long service life
Densified concrete resists tire marks, cart traffic and abrasion without peeling, blistering or flaking.
Sustainable choice
Refining the existing structural slab uses low-VOC treatments and supports LEED green-building programs.

Questions about concrete polishing
Is mechanically polished concrete slippery when clean?
Despite its mirror-like reflection, mechanically honed and densified concrete maintains high traction for foot and cart traffic when kept clean and dry, without the slick film of topical waxes.
Does concrete polishing support LEED and sustainability goals?
Yes. Polishing utilizes the existing concrete slab with no new floor covering to manufacture or dispose of, uses low-VOC silicate densifiers and neutral cleaners, and increases ambient light reflectivity.
How do we clean a polished concrete floor day to day?
Dust mop daily with microfiber to remove abrasive grit, clean with an auto-scrubber or damp microfiber pad using pH-neutral cleaner and soft pads, and wipe spills promptly.
