Villa Courtyard Floor in Al-Aqiq, Riyadh — Power Trowel Concrete

This villa sits in Al-Aqiq, on the north side of Riyadh — close enough that the King Abdullah Financial District towers show over the back wall. The owner had lived with the same problem for years: the courtyard behind the house was nothing but loose sand. It threw up dust all summer, sat unevenly underfoot, and was impossible to keep clean around the children's swing and the planted borders. She wanted it gone for good — one solid, easy-to-clean surface. She also had a clear plan for what came next: a decorative resin-bound surface laid over the top later, once the base was ready. That plan raised the bar for the concrete. Resin bound only holds up on a base that is dense, dead-flat, crack-resistant, and sloped correctly for drainage — any dip or soft spot in the slab eventually shows through the finished surface above it. The courtyard itself didn't make it easy either: a tight space hemmed in by existing planters, live drip-irrigation lines, a fixed swing frame, and a wall-mounted AC unit, with very little room for machinery to move.

Because the end goal was a resin finish, power trowel concrete finishing was the right call from the start — the helicopter trowel is what produces the dense, pore-closed slab a permeable surface needs underneath it. We set the formwork around the planters and the swing frame, then built a gentle, deliberate fall across the courtyard toward the drainage edge so water would never sit against the villa wall. The concrete went down, got screeded level, and then the waiting game began: the team watched for the exact set window before bringing the helicopter machine in. It worked the surface pass by pass — float blades first to compact and flatten, then progressively steeper blade angles to tighten and close the top. Where the machine couldn't reach, in the tight corners against the planters and the AC wall, the crew finished by hand so those edges matched the machine-troweled field exactly. As soon as the surface was done, we sprayed the curing compound to carry the slab safely through its first 48 hours in the Riyadh heat. The whole slab was finished smooth and true on purpose — a base done right the first time, so that whatever goes on top of it later sits perfectly.
