Concrete Grinding Cost Guide 2022: How much does it cost to grind concrete?

Concrete grinder

Concrete grinding can be used to achieve a polished and clean finish.

Concrete grinding can be done using an abrasive tool on rough concrete floors to reveal a smooth finish. Concrete grinding can be completed either wet or dry and is done prior to floorboards or tiles being installed. Mechanically polished concrete can achieve smoother floors of concrete slabs.

Concrete grinding involves using diamond grinding cup wheels to polish concrete for the desired finish in both external and internal area contexts.

Concrete grinding cost and factors that affect price

Depending on the size of the flooring that needs grinding the cost differs. The approximate cost for concrete grinding is between $10 - $60 per square metre depending on what is being  grinded and how large the area is.

On average concrete polishing costs $9 - $15 per square metre for jobs from 0 - 100 square metres.

From 100 - 200 square metres the average cost is $10 - $20 per square metre.

And from 200 - 1,000 square metres the average cost is $20 - $30 per square metre.

Design complexity

Depending on the complexity of the design layout of the concrete that needs grinding can also affect the cost.

For example, the concrete grinding of stairs consists of an average cost of $40 - $70 per step. As well as an average of $90 - $120 per landing depending on the size of the landing and shape.

Current state and condition of concrete floor

The current state and conditions of the concrete floor will also impact the pricing of the concrete grinding. As carpet glue removal from the concrete costs an average of $10 - $60 per square metre.

The average cost of tile glue removal from concrete is $10 - $60 per square metre as well.

Removing concrete grinding magnesite residue also comes to an average cost of $10 - $60 per square metre.

Above grade installations

Above grade installations can also differ from the average cost of concrete grinding as above grade installations are not prone to absorbing ground moisture making them ideal for most flooring types.

Raised areas including raised decks can fit into this category and the square foot area which needs actual grinding will impact the pricing of the desired finish requested by the client.

Advantages of grinding concrete

There are multiple advantages of grinding concrete including:

Concrete surface restoration

Concrete grinders remove all imperfections and inconsistencies in the material, resulting in a smooth and durable surface. Concrete polishing will ensure that any old and damaged concrete surfaces are restored and can be used for years to come if polished correctly.  Mechanically polished concrete will ensure crack repairs can also be accomplished with low maintenance after the dry or wet grinding.

Removes dirt & paint

Concrete grinding removes paint, epoxies, dirt and other remnants left on the concrete. The grinder rubs against the top layer of the surface leaving it smooth and ready for new use. Honed concrete lasts longer and creates new concrete.

New call-to-action

Preparation for floor installation

Once the grinding is complete and the smooth surface is left, any type of flooring option can be installed easily. Floor preparations are the key to any floor's long life.

Improves floor durability

The grinding process improves the floor durability, as grinding concrete ensures that the floors are always in perfect condition and ensures the longevity of the floor but also durability.
