There were many aspects to this project- a retaining wall, pool deck, pool coping, wall cap, and a covered patio. The homeowners were unhappy with the appearance of the concrete and rubber coping around their pool, and also wanted to reduce the size of the concrete area around the pool. The railroad tie retaining wall had to be removed and the pool equipment needed to be relocated. The existing concrete was covered with a polymer modified concrete resurfacing product with a knockdown finish and simulated grout joints. Cracks were beginning to transfer through and the surface was delaminating. There had been an original pour around the pool and an add-on area poured at a later date.
We proposed to eliminate the add-on area, fabricate a cast-in-place cantilevered concrete coping, and then resurface the original pour around the pool with a heavily reinforced unbonded concrete overlay. We started with demolition of the area to be eliminated and used the debris for fill in an unusable area of their property. This eliminated trucking and recycling fees, and provided a substantial base for the pool equipment and filter pad. Next, we dismantled the railroad tie wall and found a deteriorating brick retaining wall behind it, which we also dismantled and used for fill.
We rebuilt the wall with concrete block pinned to the original footing, and provided drainage and weep holes. It was then faced with cultured stone and capped with our high performance concrete to match the look and color of the coping. This wall now also functions as a seat.
The track used to support the rubber coping could not be removed, so it was incorporated into the coping. Plumbing lines were replaced and run toward the new filter pad location. We then poured a heavily reinforced, unbonded concrete overlay embossed with a texture and pattern to emulate an ashlar stone. The coping was done in a contrasting color to the pool deck. A darker brown was chosen for the deck area in order to set off the pattern.
Our Process. We create an unbonded cast in place concrete tile or stone. Our high performance concrete is mixed on site by a crew of 4. We use integral synthetic iron oxides rather than dry shake to provide a long lasting color. We also use a high range water reducer as well as internal water repellant to create an extremely durable product. All of the concrete is reinforced with wire mesh, steel rods, structural synthetic fibers, nd PVA fibers. This surface is a minimum of 1 inch thick and designed to react independently from the existing concrete. Impressions are placed in the concrete creating a cast-in-place concrete tile or stone. Each of the impressions in the concrete act as a geometrically patterned crack control system. The concrete surfaces are textured to provide slip resistance as well as visual interest. Unlike texture mats, we can increase or decrease the texture at our discretion. All of the impressions are grouted to complete the look of a custom concrete tile or stone. The entire surface is rubbed with a grindstone to eliminate any sharp edges that might be uncomfortable for barefoot traffic. Finally an acrylic cure and seal is sprayed on the entire surface to provide stain resistance and a satin sheen. The extensive reinforcement, both horizontally and three dimensionally, is a major benefit of our type of resurfacing.
