Concrete Shot Blasting
For slabs too large or too contaminated to grind. Steel shot strips coatings and leaves a clean, uniform profile at production scale.
When grinding is the wrong tool
Very large open slabs
On big warehouse decks, grinding becomes a schedule problem. A blaster covers ground far faster and leaves a consistent profile across the whole area.
Heavy contamination
Where a slab is heavily coated or contaminated, blasting removes the material and takes the surface back to sound concrete in one pass.
Coatings that need real profile
Heavy-build coatings and urethane cement need a deeper profile than grinding typically produces. Blasting delivers a CSP 3 to CSP 6 profile.
Where blasting beats grinding, and where it does not
They are not competing methods, they suit different conditions. Most large projects use both, with the blaster on the open field and grinders where it cannot reach.
Where blasting wins
Large open areas, heavy coating removal, and any specification calling for a deeper CSP profile. Production rate is the main advantage.
Where blasting does not fit
A blaster cannot work tight to walls, into corners, or around fixed plant. Those areas are ground instead, which is why most jobs run both.
Four steps, start to handoff
Site assessment
We walk the slab, check its condition, test for moisture where it matters, and give you a clear scope with no vague line items.
Blast the open field
Steel shot is thrown at the slab and recovered in a closed loop, stripping the surface and profiling it as the machine advances.
Grind the edges
Perimeters, corners and areas around fixed equipment are ground to match the profile the blaster achieved on the open floor.
Clean handoff
Dust is collected at the machine throughout, and the slab is handed off clean and uniformly profiled for the next system.

Common questions about concrete shot blasting
How much profile does shot blasting leave?
Typically a ICRI CSP 3 to CSP 6 profile depending on how the machine is set. The coating manufacturer specifies which level their system needs.
Is it dusty?
Far less than people expect. The shot is recovered in a closed loop and dust is collected at the machine, which is why blasting suits occupied buildings.
Can you blast right up to the walls?
No machine can. Perimeters and corners are ground to match, so the whole floor ends up at a consistent profile.
How large a floor can you handle?
AWSP has taken projects up to 160,000 square feet. Production rate is exactly why blasting gets specified on slabs that size.
