Mechanically Polished Concrete (MPC)
Mechanically Polished Concrete (MPC) is a premium flooring solution that combines precision grinding, honing, and polishing to create a durable, aesthetically appealing surface. The process begins by grinding the concrete to the desired level of aggregate exposure—whether a surface polish, partial exposure, or heavy exposure. As the process progresses, progressively finer diamond abrasives are used to smooth the surface and remove any imperfections left by previous stages.
To enhance the concrete’s durability, colour, and shine, specialized grouting chemicals, along with potassium and lithium densifiers, are applied alongside the diamond tooling. These treatments not only strengthen the concrete but also improve its appearance, contributing to the floor’s overall aesthetic appeal. The ability to achieve both low and high-gloss finishes is a result of the combination of chemical treatments and the fine-tuning of the surface through polishing.
MPC offers a high level of customization, allowing for a variety of aggregate choices and the integration of coloured oxides to create a truly unique and striking look. This process results in a sustainable, low-maintenance flooring option that can withstand heavy traffic while maintaining its beauty over time. Whether you prefer a sleek, high-gloss finish or a more understated, low-gloss look, MPC delivers a solution tailored to both your aesthetic preferences and practical needs.
Grind and Seal
Grind and Seal is a finish that does not involve polishing the concrete. Instead, it focuses on the initial stages of the polished concrete process, providing a durable and attractive surface while remaining a more affordable and straightforward option.
The process begins by grinding the concrete to expose the desired amount of aggregate, similar to MPC, and then refining any major gouging or imperfections in the surface. In most cases, grouting chemicals can be applied to fill any cracks or pitting in the floor, ensuring a more uniform appearance. After grinding, the surface is vacuumed, detailed, and prepared for the application of a topographical sealer.
One of the key differences between Grind and Seal and MPC is in the finishing process. While MPC uses a series of refining steps to achieve a smooth, glossy finish and utilizes penetrating sealers to protect the surface from within, Grind and Seal focuses on sealing the top of the concrete surface with a topical layer. This deepens the colour and enhances the finish, sheen is determined by the type of sealer applied, which can range from matte to high gloss.
This makes Grind and Seal an excellent option for those who want a more cost-effective alternative to polished concrete while still benefiting from a durable, attractive floor. It is commonly used in garages, sheds, retail and commercial spaces, and outdoor entertaining areas, when an easy-to-maintain surface is desired but the high-gloss, refined finish of MPC isn’t necessary.
Pavilion Finish
The Pavilion Finish is an external concrete finish similar to Grind and Seal, with a few key distinctions that make it ideal for outdoor applications. After the honing or grinding process, a light Chemical etch is applied to the surface. This step not only helps to create a more slip-resistant finish but also cleans and prepares the surface for the application of the sealer.
Unlike Grind and Seal, no grouting chemicals are used in the Pavilion Finish. However, the acid etch effectively opens the concrete surface, ensuring better adhesion of the sealer while enhancing traction. This finish can also be combined with a non-slip additive to further increase its safety, making it a perfect choice for high-traffic outdoor areas such as patios, driveways, pool surrounds, and entertainment spaces.
The Pavilion Finish offers durability, functionality, and aesthetic appeal, all while providing a safe, slip-resistant surface. Whether for residential or commercial projects, it delivers an excellent option for exterior concrete that stands up to weathering and heavy use while maintaining a clean, attractive look.
Heavy Aggregate Exposure
Heavy Aggregate Exposure is a striking choice for polished concrete surfaces, combining durability, aesthetic appeal, and customization options. This finish reveals the natural beauty of the aggregate, creating a polished, one-of-a-kind look that can make a bold statement in any space.
The process effectively eliminates placement imperfections, mistreatment, and surface contamination, ensuring a flawless aesthetic. By exposing your chosen aggregate and oxide colours, this finish highlights the depth and character of the materials, making it a highly customizable option that can complement various design themes.
With an average surface removal depth of 3mm to 8mm, the process uncovers a beautiful, natural surface, perfect for both residential and commercial projects. Whether you’re looking to enhance a home or create a distinctive feature in a commercial space, Heavy Aggregate Exposure provides a timeless and durable finish that adds style and sophistication.
Partial Exposure
Partial exposure offers a subtle and refined concrete finish, balancing exposed aggregate with smooth, grouted surfaces for a minimalist yet distinctive look.
The process begins by leveling the floor, removing high points to create a flat surface. This exposes some aggregate in the high areas while leaving the lower areas smooth, resulting in a unique blend of textures.
This finish is perfect for those who prefer a minimalist aesthetic. It softens the look of fully exposed aggregate while adding subtle texture and character, making it a popular choice for modern, understated designs.
With an average surface removal depth of 1mm to 3mm, partial exposure maintains the structural integrity of the concrete while revealing just enough aggregate to achieve a balanced and elegant effect.
If you’re seeking a unique and understated finish that balances texture and simplicity, partial exposure is an ideal choice.
Surface Polish
Surface polish is a highly sought-after finish in the industry, celebrated for its sleek, minimalistic aesthetic and refined appearance.
To achieve the best results, it’s crucial to communicate your desire for a surface polish finish before the concrete is poured, ensuring a flat and closed-off surface.
The polishing process removes only minimal surface contamination or irregularities, creating a flawless finish. However, due to the super-fine diamond tooling, deep stains, significant damage, or grouting cannot be addressed.
With an average removal depth of 0.2mm to 2mm, this finish preserves the natural integrity of the concrete while delivering a smooth and polished surface.
Surface polish is the ideal choice for those seeking a clean and contemporary look.
Industrial Surface Mechanical Polished Concrete (MPC)
Industrial Surface Mechanical Polished Concrete (MPC) is a four-step system specifically designed for large-scale projects, offering a durable, cost-effective, and aesthetically appealing flooring solution. Ideal for industrial spaces like warehouses, factories, and commercial properties, MPC provides a long-lasting, low-maintenance surface that enhances the overall space.
The process begins with polishing the concrete surface using progressively finer diamond abrasives to remove imperfections and achieve a smooth, even finish. In conjunction with the polishing, a range of densifier products are applied to penetrate the concrete, strengthening the surface and enhancing its durability. Densifiers increase the density of the concrete, improving abrasion resistance, reducing dusting, and enhancing the shine of the polished surface. This treatment also helps to make the concrete more resistant to staining and wear, improving its longevity.
The surface is then polished to the desired gloss level. MPC offers flexibility in achieving different levels of sheen—from a subtle matte finish to a high-gloss shine. The reflective surface not only enhances the aesthetic appeal of the space but also helps brighten the area by improving natural and artificial lighting.

Cracks in Concrete – A Manageable Imperfection
Concrete, like any material, has its imperfections—cracking is a natural occurrence influenced by various factors. Understanding and addressing these cracks is key to maintaining a durable and aesthetically pleasing surface.
Concrete cracks can result from factors such as shrinkage, temperature fluctuations, and structural stress. While some cracking is inevitable, proper curing, controlled water content, and expert placement techniques can significantly minimize the risk.
Our grinding and grouting process not only enhances the surface but also fills cracks effectively, making it ideal for achieving a smooth, durable finish. For concrete unsuitable for surface polishing, we recommend partially or fully exposed aggregate finishes to ensure the best results.
As an alternative, we can mix site-specific compounds to patch and repair cracks. While these compounds may not achieve a perfectly seamless finish, they remain a viable option for addressing surface imperfections when grouting isn’t suitable.
Due to concrete’s rigidity, repaired cracks may occasionally re-open. If this happens, our team can assess the situation and recommend the next best steps to restore your surface to its optimal condition. Contact us for a tailored solution.
