Step 1: Excavation & Sub-grade Preparation
We start by preparing the site of concrete installation by excavating the area where concrete is to be poured. The depth of excavation depends upon the grading and layout of the construction site. The subgrade provides the main difference in the overall performance and structural integrity of the slab. Gravel is added to the site and well-compacted to prevent drainage and soil erosion under the concrete.
Step 2: Forming
Forms are often made from metal, wood, or plastic and attached to stakes in order to contain the concrete in the desired area. A strong form in good condition provides the optimal slope for drainage, which is of utmost importance in the harsh Canadian weather.
Step 3: Reinforcing Steel
Installing reinforcement steel in the form of steel reinforcement bars or wire mesh provides structural functions and support for the concrete slab. This provides structural capacity, reduces joint maintenance, increases impact resistance, and controls cracking.
Step 4: Concrete Placement
A T & R approved ready mix truck will arrive at the placement area and pour concrete. Our team of concrete experts will handle the concrete to prevent segregation and keep a clean working area.
Step 5: Concrete Colour
There are two basic techniques to apply colour to concrete. The first is integral color in which liquid colour is poured into the concrete ready mix truck. This method allows the colour to combine with the concrete and the slab obtains colours throughout. The second option is the broadcast method in which colour hardening powder is applied directly to the freshly poured concrete surface. The colour hardener will penetrate the top of the concrete slab 1/8″ and colour thoroughly. Be sure to ask our design experts about our colour options and which method best suits your job.
Step 6: Concrete Finishing
The most critical stage of the concrete pour process is finishing the concrete. There are two important factors at this stage: grading the concrete and bringing the cement paste to the top. This step is essential as it prepares the canvas for decorative stamping.
Step 7: Concrete Stamping
The window of time in which concrete must be stamped is relatively short and T & R has a strong team of concrete experts to assist in this process. Pre-textured stamps are applied to the concrete in order to create depressions and many custom designs. Ask our team of design experts about different options for stamps.
Step 8: Form Removal
Once the concrete is dry, the forms that were installed to contain the area of concrete and create sharp edges are removed. Our team of experts will be sure to remove it at the optimal time.
Step 9: Control Joint Installation
The cutting of control joints (also called contraction joints) provides stress relief at optimal locations determined by our experts. This can help prevent conspicuous cracking although not all cracking can be prevented due to unmitigated stress caused by the natural movement of the earth, temperature changes, and drying shrinkage.
Step 10: Site Clean-Up & Pressure Washing
Our team of T & R experts are always sure to clean up the site of installation so you don’t have to. Once the area is cleaned, it is pressure washed to remove excess release and dust from the surface.
Step 11: Sealing
No job is complete without sealing the concrete with a T & R approved sealant. The application of a sealer will add sheen to the surface (ask your design expert what they recommend as sealants range from satin to high gloss); enrich the colour of the concrete; block penetration of stains from chemicals, leaves, oil, grease, and dirt; and reduce the chances that efflorescence will discolour the surface.
Step 12: Post-Construction Services
If you have any questions or concerns about the concrete installation process, our friendly and professional staff are always ready to assist you. For us, the job is never done until you are satisfied.
The installation process is subject to changes depending upon your unique job. Steps may be added or removed as each job is unique to your needs. Ask our experts if you have any questions about the steps of your distinct job.
