Steel / Rebar

Duration: 1-2 days | Building the skeleton

The steel reinforcement phase transforms your excavated footprint into the definitive framework of a custom pool. Our skilled crews install a complex, custom-engineered grid of high-tensile steel rebar that spans the entire floor, walls, steps, lounging benches, and any integrated spa areas. This steel cage serves as the uncompromising structural backbone of your pool.

Each piece of rebar is carefully hand-bent and tied to follow the exact, fluid contours of your custom design. The meticulous spacing, sizing, and placement are dictated entirely by your structural engineer’s specifications, ensuring the pool shell can easily withstand the immense pressure of the surrounding soil, the weight of the water, and the seismic forces common to Southern California.

Before a single drop of concrete is poured, we coordinate a mandatory, comprehensive inspection with your local building department. The city inspector meticulously verifies that every inch of our steel placement perfectly matches the approved engineering plans. Only after we pass this critical quality checkpoint do we proceed to the shotcrete application phase, guaranteeing that your pool’s foundation is built to last a lifetime.

Precision Detailing and Advanced Integration

Beyond providing raw structural strength, the rebar grid acts as the essential anchoring system for your pool’s internal plumbing and electrical components. During this phase, our technicians carefully secure all PVC light niches, return lines, main drains, and spa jets directly to the steel framework so they remain perfectly positioned when the heavy concrete is applied. Additionally, a licensed electrician connects a continuous copper wire to the rebar grid in a critical process known as “bonding.” This creates an invisible, highly effective electrical safety net around the entire pool, keeping your family completely safe from stray voltage and ensuring the structure exceeds strict National Electrical Code standards.

To guarantee absolute longevity, our crews also meticulously elevate the entire steel cage using specialized concrete blocks, known in the industry as “dobies.” This crucial step prevents the rebar from ever touching the raw earth, guaranteeing that the steel will be fully encapsulated right in the center of the shotcrete shell. By completely sealing the high-tensile steel away from groundwater and soil moisture, we eliminate the risk of internal rust or long-term structural degradation. It is this level of unseen, obsessive preparation that allows PoolMax to deliver a flawless, rock-solid foundation for your backyard sanctuary.
