Our Stamped Concrete Installation Process
The first step in creating a beautiful concrete slab is to build the base. In Ottawa we have a major freeze thaw cycle due to the drastic temperature changes of our climate. Therefore it is important to dig deep and properly compact the base material. We dig down 12" and lay landscape fabric at the bottom of the excavated area to separate the soil from the granular "A" stone base material. We then add about 8" of granular "A" crushed stone compacting every 2.5" or so. This ensures a solid base that will not shift during freeze thaw cycles and helps prevent cracking.
After the base is in place we set the forms. The forms are set to conform with the design plan and to ensure proper water drainage. Our forms are built from wood and nailed to either steel or wooden stakes. We coat the forms with oil before pouring so that they come apart from the concrete easily. Just before the pour we double check our form placement and make any required adjustments.
Concrete is delivered to the work site. If we are using coloured concrete the dye will be mixed in at the concrete plant. The concrete is poured inside the forms, raked and screeded out to grade. Next we bring the concrete to a smooth finish to prepare for stamping.
With the surface and edges brought to a smooth finish we then wait for the concrete to reach the right level of firmness before stamping. The first step in stamping is to broadcast release powder evenly over the slab. Concrete powder release agent forms a moisture barrier between the stamps and wet concrete to allow the stamps to release easily from the concrete. In addition to releasing agents the powder adds colour variations and highlights to the textured surface.
After stamping we wait 24 - 36 hours and then sweep off excess release powder with a soft broom. More release powder is cleaned off with water, dish soap and a soft brush. We also do the crack control cuts at this time so that the concrete cracks in these precut lines and doesn't create unsightly cracks in your new surface. About one week after pouring we will do a final wash with acid to remove excess realease powder and prepare the surface for sealing.
With the surface washed and cut and after waiting one week or so for the concrete to cure we finally apply a coat of sealant. Concrete sealant helps prevent damage, corrosion and staining caused by oil, chemicals, salt, grease, weather exposure, UV rays, and moisture. Sealing also accentuates the colours and textures in the stamped surface. About one month after pouring we will often add another coat of concrete sealant.

Found myself in a panic situation this August when the company replacing my garage door advised that I needed an entire new garage floor in order for the doors to sit properly (to be addressed in a review for that company).
We had a great experience with Jonathan from Coliseum Concrete and Interlock. He came by a few weeks ago to quote us on resealing our stamped concrete. He’s one of the few in the area willing to repair and seal concrete he didn’t originally install, which really stood out.
Jonathan and crew arrived when they said they would, did the work quickly, and handled all my questions and concerns. The new steps, landing and walkway look great. Their cleanup was thorough. I’m entirely impressed, and will bring them back for garage floor work. Thank you !
We hired Coliseum Concrete to replace our garage floor, driveway, front step, pathway and the backyard patio. Jonathan and his crew were excellent and worked diligently everyday and the projects were finished on time as Jonathan promised that they would.
We used Coliseum to take out the grass in the front yard and put interlock to extend our driveway. The quality of service was exceptional and on time. They took the time to do create a good plan beyond our satisfaction and also made recommendations to add better aesthetics to our plan
We had an excellent experience with Jonathan and his team. They transformed our under deck area into a fully usable space. The team worked hard for the three days they were on-site. The workmanship was exactly what you would hope for a large job as ours (650 sq ft). The last day they multitasked and sealed the concrete while others were cleaning up and putting down all new soil. I am extremely happy with the end product and would recommend them to anyway.
