Understanding Concrete Levelling and High-Point Grinding: A Professional Guide

Concrete Levelling and High-Point Grinding

Each concrete floor has its story. After levelling hundreds of floors across Perth, like warehouses, garages, and commercial showrooms, one thing is certain: precision and preparation make all the difference.

Uneven floors do more than just look bad; they impact performance, safety, and long-term durability. This is why iCOATWA offers professional concrete levelling and high-point grinding services designed to correct surface irregularities, enhance coating adhesion, and create a smooth, even foundation ready for use or finishing.

Our Perth-based team has specialised in transforming imperfect floors into perfectly level, functional surfaces, combining hands-on experience, modern equipment, and an eye for detail that comes from years of trade.

Why Level Concrete Floors?

Why Level Concrete Floors? Uneven concrete gives rise to far more problems than you can imagine. Surface level affects equipment speed and effectiveness, as well as how long the material lasts on the floor.

Employers must follow OSHA’s Walking-Working Surfaces standards to make certain that hazardous floor conditions are addressed to prevent work-related injuries.

We inspected a warehouse just last week where uneven concrete caused:

  • Forklift instability during operation
  • Trip hazards in walkways
  • Machinery and flooring are subject to uneven wear.
  • Pooling water after cleaning
  • Equipment alignment issues

Over time, these problems are causing rising maintenance expenses and reducing your floor’s lifespan. That is why concrete levelling is one of the most worthwhile long-term investments in both buildings, both residential and commercial: a stable, smooth bedrock ready for proper cleaning and coating preparation.

How We Assess Floor Levels

Grinding and levelling start only after a professional diagnosis gives everyone a proper ground to play on, and you should do so first. We don’t make guesses; we measure, map and evaluate every part of your concrete surface.

Professional Assessment Tools

We measure every floor on a state industry-grade survey, using these tools:

  • Laser levels: To bring accuracy closer to range across large areas.
  • Straight edges: To detect dips and raised sections.
  • Digital floor monitors: For detailed surface mapping.
  • Moisture metres: To avoid future coating issues.

What We Look For

A good concrete assessment is not just about what you can see.

We inspect:

  • High and low points.
  • We also look for crack patterns and areas that have been heaved.
  • Surface condition and texture.
  • We also consider the concrete’s hardness and moisture content.

Knowing these parameters from the start means that the correct levelling solution is selected and performed accurately.

High-Point Grinding: When and Why

High points are a common and often overlooked problem for concrete surfaces. They occur due to settling, incorrect first-time installation, or expansion when moisture conditions dictate.

We still remember one of the homes in a local garage we worked on that was flooded, where the concrete had swelled in several spots. An unhappy homeowner complained that the floor drainage was not uniform and that water was pooling in certain areas.

After a thorough evaluation, we focused on high-point grinding to fully restore the floor’s level and performance.

Finding High Points

Then we laser plan the whole floor so we know where things are and use laser precision to locate:

  • Peak or raised zones
  • Transition zones between slabs
  • Surface-level differences

Professional Grinding Process  

Once we have a map, we have a guided step-by-step so we slowly and safely take your load out:

  • High areas should be marked for targeted work.
  • Prepare to operate for HEPA dust control.
  • The grinding of a system by diamond-tipped tools.
  • Consistent verification of level status.
  • Surface treatment to provide the expected smoothness.

The outcome? A floor that is not only level but also perfect for painting, sealing, or finishing off. Learn why coating your levelled concrete floor is one of the best decisions you can make for long-term protection and performance.

Levelling Methods We Use

The Techniques at Levelling. Each job is different. Depending on the level of trouble and demands, we might use one or more professional techniques.

  1. Mechanical Grinding

Ideal for small changes, mechanical grinding uses industrial diamond grinders to lower elevated areas and smooth rough sections.

It’s ideal for:

  • High point removal
  • Edge and corner detailing
  • Surface preparation for coatings
  • Spot corrections for uneven concrete
  1. Self-Levelling Compounds

In large lower areas, we also apply self-levelling compounds, so the solution will have a smooth surface.

This method is perfect for:

  • Wide surface discrepancies
  • Large commercial areas
  • Floor prep for vinyl, epoxy, or tile
  • Quick turnaround projects
  1. Combined Approach

There are multiple floors in Perth that require hybridity. On one recent retail store floor, a high-point grinding solution was required first, then a thin layer of self-levelling compound was used to finish it completely.

It combines precision grinding that ensures the optimal product on the ground with strength, beauty and durability.

Real Project Example

One particular project that really made us happy was a commercial garage that we visited with years of uneven wear. The client, Colin, later said, “It has transformed my garage into an area I’m very proud to show off.”

Our procedure involved:

  • Detailed site assessment and level mapping
  • Identification of multiple high points
  • A step-by-step grinding plan
  • Consistent progress checks using laser systems
  • Application of self-levelling compound
  • Final surface preparation for coating

All in all, the floor was flawless, smooth, and prepared for years of heavy use. Another happy Perth client.

Common Challenges We Handle

  1. Moisture Issues

Moisture is a silent threat to concrete coatings and levelling compounds. Industry standards like ASTM F2170 and the American Concrete Institute’s ACI 302.2R guide emphasise the critical importance of moisture testing before applying any flooring or coating system.

We always test for moisture before starting, ensuring proper curing and adhesion. As one of our clients, Michael, said:

“These guys are professionals… there was minimal mess, and everything was handled properly.”

  1. Time Constraints

We understand that time matters, especially for commercial spaces. Our efficient workflow ensures quick turnaround without sacrificing quality. Walter mentioned:

“We were in a tight time frame, which the guys were able to achieve for us.”

  1. Surface 

Variations. Every floor is different, so we adapt.

We consider:

  • Concrete hardness and density
  • Age and curing stage
  • Previous coatings or repairs
  • The required finish can be matte, gloss, or industrial.

This flexibility ensures optimal results for any environment — from garages and workshops to large industrial floors.

Professional Equipment Matters

The kind of finish given depends largely on your used tools. This is why iCOATWA invests in the latest equipment geared towards precision and cleanliness.

Our setup consists of:

  • Industrial-grade diamond grinders
  • HEPA-filtered dust extraction systems
  • Advanced laser levelling technology.
  • Professional measuring and mapping tools

Every piece of equipment enables us to deliver consistent, dust-free, and high-quality results across every project — big or small.

Professional Advice from iCOATWA

Don’t wait until something, like sloping, pooling, or cracks in your concrete, gets worse. Small irregularities like these can even cause structural problems or coating failure.

Our experts are on hand to inspect your floor and suggest the best approach, whether that’s minor high-point grinding or a full levelling treatment.
