What is Shotcrete?
Shotcrete is a premium method of concrete pool construction where a pre-mixed, quality-controlled concrete blend is pneumatically applied at high velocity to create your pool’s structural shell. Unlike gunite, which mixes dry concrete with water at the nozzle on-site, shotcrete arrives fully batched and consistent from the very first spray to the last.
The result? A denser, stronger pool structure with less room for human error and more predictable long-term performance.
Here’s what sets it apart: when we build a shotcrete pool, we don’t simply shoot concrete into an open excavated hole. We first construct a precision-formed wall system, reinforced with a steel rebar grid, just like a poured foundation wall on a high-end custom home. Shotcrete is then applied to that engineered form, creating a monolithic shell with optimal thickness and integrity throughout.
For St. Louis homeowners, that matters. Our freeze-thaw cycles, heavy rains, and summer heat extremes demand a pool structure that was engineered for the long game, not just built to pass inspection. Shotcrete delivers exactly that.

SHOTCRETE POOLS FREQUENTLY ASKED QUESTIONS
Is shotcrete the same as gunite?
Shotcrete and gunite are both concrete pool construction methods, but they are not the same thing. Gunite uses a dry concrete mix that combines with water at the nozzle during application, which means consistency depends heavily on the crew’s skill and conditions that day. Shotcrete arrives fully pre-mixed and quality-controlled, resulting in a denser, more uniform shell with less room for variation. At Meramec Pools & Outdoors, we build exclusively with shotcrete because the consistency and structural integrity are simply better.
How long does a shotcrete pool last?
A properly built shotcrete pool can last 50 years or more with routine maintenance. The key word is “properly built.” Shotcrete’s pre-mixed composition and formed-wall construction method create a monolithic shell with superior compressive strength, which is especially important in a climate like St. Louis where freeze-thaw cycles put real stress on pool structures every year.
How much does a shotcrete pool cost in St. Louis?
Unlike fiberglass pools with fixed shapes, shotcrete pools are fully custom, so the final investment reflects your specific design, site conditions, and selections. The best way to get an accurate number is a complimentary design consultation with our team!
How long does it take to build a shotcrete pool?
Most custom shotcrete pool builds take between 8 and 16 weeks from excavation to swim-ready, depending on design complexity, permitting timelines, and weather. The process involves excavation, steel reinforcement, shotcrete application, plumbing, finish work, and startup. One advantage of starting in fall or winter is that your pool can be ready to open the moment summer arrives, with no waiting.
Is a shotcrete pool better than a fiberglass pool?
It depends on your priorities. Shotcrete pools offer complete design freedom, any shape, size, depth, or architectural detail you can imagine, and a structural durability that’s unmatched. Fiberglass pools install faster and require less maintenance over time. For homeowners who want a truly custom backyard environment built around their home and lifestyle, shotcrete is the superior choice. For those prioritizing speed and simplicity, fiberglass may be a better fit. Meramec builds both, so we can help you make the right call for your specific situation.
Can a shotcrete pool be any shape or size?
Yes, that’s one of the defining advantages of shotcrete construction. Because the pool shell is formed and built on-site rather than manufactured in a factory, there are virtually no limitations on shape, depth, or design complexity. Freeform resort-style pools, modern geometric designs, vanishing edges, integrated spas, tanning ledges, and dramatic water features are all achievable. If you can design it, shotcrete can build it.
