Upon arrival, the first step is to identify any potential problem areas, such as underground utilities (gas, electric, cable, or telephone lines), septic tanks, water sprinklers, and more. This allows us to avoid any damage during excavation.
Before we begin your concrete project, we carefully assess every aspect to ensure there are no obstacles that could hinder or delay our work. We also review the plans, evaluate site access, and prioritize the safety of everyone involved, including employees and local residents.
Next, we hold a discussion among the team to review the work plans and safety procedures. Each employee is then assigned specific tasks based on the details outlined in your contract.
All excavation is performed by hand and with small machinery.
Crushed stone is typically delivered to the site, either in a laneway or a barricaded area on the road, depending on the site conditions and accessibility.
We dig according to the project plans, usually up to a depth of 12 inches, after which the crushed stone is placed and thoroughly compacted.
Once the excavation is complete, we proceed with installing the forms, which are typically made of either metal or wood.
Next, we add and compact the crushed stone to ensure a solid foundation.
For projects involving staircases, porches, or other unstable sites, we use Sonotube fiber forms. These lightweight, single-use forms help create cylindrical piers or bases to stabilize the structure.
We then lay down the steel mesh, and depending on the project, we may also incorporate rebar for additional reinforcement.
With the preparation complete, the site is now ready to receive the concrete!
Whenever possible, we position the cement truck directly at the project area to save time. If this isn’t feasible, we transport the concrete using wheelbarrows.
Finally, the freshly poured concrete is leveled and troweled to ensure a smooth, even finish.
Once the concrete has set and hardened, we remove the forms and cut the control joints.
A diamond-bladed saw is used to create these control joints.
If necessary, stained borders are also cut into the concrete in the same manner, but with a smaller diamond saw for precision.
After the cutting is complete, we pressure wash the concrete and its surroundings to remove any dust. In some cases, an acid wash may be required to clean off any excess colored release powder.
Note: The color may appear slightly different during application, as the true color is revealed only after the concrete, known as 'green concrete,' has fully cured. This curing process typically takes a minimum of 28 days.
When we execute a natural, plain grey concrete project, it can be finished two different ways.
A broom finish will produce a rough surface. This finish also provides a slip-resistant texture to the concrete's surface.
If a smooth finish is desired, the concrete is then finished with a power trowel machine.
To create your stamped concrete project, you must choose a minimum of two colors. The first color is the primary base color, which is mixed directly with the concrete in the cement truck. This mixing process takes place on-site at the concrete plant (Lafarge), ensuring the color blends seamlessly with the cement for a uniform, vibrant finish.
Once the concrete is poured and troweled, the second color, a colored 'release powder,' is applied to the surface. This release powder serves two purposes: it enhances the appearance of the concrete with marbling and shading effects, and it prevents the rubber stamps from sticking during the stamping process.
The stamps are then placed on the wet, workable concrete and gently tamped down with a specialized tamping tool, using a series of light taps.
Various rubber stamps are available, each with different patterns. These stamps create the desired texture and pattern in the concrete by embedding or engraving specific details into its surface.
Borders, typically chemically stained with a color chosen by the client, can also be applied depending on the project's design.
Staining can be done on both very old and brand new concrete. However, it's important to note that the stain will not be uniform. Stained concrete surfaces are typically shaded with varying tones, hues, and nuances, adding depth and character to the finish.
The chemical stain is applied using a brush, roller, or air sprayer, depending on the desired effect.
The stain reacts with the concrete and embeds into the surface, usually within 24 hours, after which the excess residue is washed away.
Once the concrete has dried, a sealer is applied to the entire surface.
The sealer is applied in the same manner as the stain, and usually one coat is sufficient to provide a uniform, attractive sheen.
This sealer serves as a protective layer, shielding the concrete from harsh weather conditions and preventing damage from any foreign materials that may come into contact with the surface.
Maintaining your concrete is essential to preserve its brightness, shine, and protection.
Regular cleaning and sealing of your stamped concrete are necessary, and the frequency depends on factors like traffic, water exposure, and contact with chemical products.
Concrete surfaces can accumulate dust, making it difficult to assess their true condition. However, once cleaned, you’ll notice a significant improvement in the concrete’s appearance. To prevent the buildup of dust and debris, we recommend scheduling periodic cleanings.
We suggest sealing your concrete project every year to maintain its durability and appearance.
Now that your stamped concrete project is complete, your space is transformed with a beautiful, durable surface that will impress for years. From the excavation to the final finishing touches, every step has been carefully executed to ensure a high-quality, long-lasting result.
With expertly crafted patterns, vibrant colors, and a seamless finish, your stamped concrete will not only enhance the aesthetics of your property but also provide a solid, dependable foundation for daily use.
