Shotcrete Concrete Pool: Process, Advantages, and Cost Estimate
A shotcrete pool is the most versatile and durable option for building custom-built pools. Unlike concrete block or precast systems, shotcrete allows for the creation of pools of any shape, size, and depth, adapting perfectly to uneven terrain and custom designs. In Spain, more than 60% of newly built pools are constructed using this technique.
What Is Shotcrete?
Gunite, or shotcrete, is concrete sprayed at high pressure through a pneumatic hose. The result is a monolithic structure of high density and strength with no construction joints that perfectly conforms to the shape previously formed with rebar. The spraying pressure compacts the concrete, achieving a compressive strength exceeding 350 kg per square centimeter.
Step-by-Step Construction Process
First, the ground is excavated to the project dimensions plus 20–40 cm on each side. Next, rebar is installed using 12-mm corrugated steel bars in a 20x20-cm grid. Then, pipes and skimmers are installed prior to the gunite application. The shotcrete machine applies concrete in layers up to 15–20 cm thick in a single continuous workday. Curing takes at least 28 days, during which the concrete must be kept moist. Finally, the waterproof finish is applied: epoxy paint, mosaic tiles, mortar plaster, or reinforced membrane.
Advantages of shotcrete over blocks
It allows for completely free design: curves, organic shapes, varying levels, beaches, and integrated hot tubs. The monolithic, joint-free structure is more resistant to ground movements. The shotcrete application itself is completed in a single day. It works on rocky or sloped terrain where precast blocks are impractical.
Prices for shotcrete pools in Spain in 2026
A basic 6x3-meter rectangular pool costs between 12,000 and 20,000 euros. A standard 8x4-meter pool costs between 18,000 and 28,000 euros. A 10x5-meter free-form pool costs between 25,000 and 45,000 euros. Luxury pools with a beach area and built-in hot tub can exceed 50,000 euros. The breakdown for an 8x4-meter pool is approximately: excavation 2,000–4,000 euros, rebar and shotcrete 5,000–9,,000 euros, equipment 3,000–5,000 euros, waterproofing 3,000–7,000 euros, and perimeter flooring 2,000–4,000 euros.
Reinforced PVC Membrane: The Ideal Finishing Solution for Shotcrete Pools
When applied over a shotcrete structure, reinforced PVC membrane offers the best performance as a final waterproofing system. Its flexibility compensates for minor movements and microcracks in the curing concrete, guarantees complete watertightness from day one, and facilitates maintenance throughout the pool’s entire service life. The extensive catalog of colors and textures allows you to customize the appearance without sacrificing functionality.
