Did you know that you can build a pool with insulated concrete forms? Like insulated concrete form (ICF) structural walls for homes and commercial buildings, ICFs improve in-ground swimming pools' energy efficiency and durability and speed of construction, benefiting consumers, builders and architects alike.
For those who might be unfamiliar with ICF construction, the process is simple. Builders stack hollow-reinforced foam blocks to the desired height across the perimeter of the structure and then carefully fill them with concrete. The insulating power and overall strength of ICFs protect against thermal bridging or heat loss, regardless of the exterior temperatures — a concept that carries over well into swimming pool applications.
Read on to learn about the five main benefits of using insulated concrete forms for swimming pools.
ICFs provide continuous insulation on the exterior, interior and bottom of the pool, helping stabilize the pool's temperature. For those who choose to heat or cool their pool, this can reduce energy costs by 60%. Traditionally-built pools can lose up to 80% of their heat through the sides and bottom because the ground conducts heat easier than the surface air.
In addition, stabilizing the pool's temperature can elongate the pool’s season, which is a significant benefit for homeowners in colder climates.
ICFs’ concrete core and foam exterior provide strength and integrity for longer-lasting pools with less maintenance.
Traditional concrete pools require extensive upkeep and costly water treatments to preserve the concrete's strength and to prevent cracks, pores and algae growth, which can lead to resurfacing the entire pool.
ICF pools solve this problem by surrounding the pool walls with EPS foam to create a quality waterproof barrier that shields the concrete from moisture infiltration.
Spray concrete crews for pools are in high demand, hard to schedule and are difficult to coordinate. Although many pools are built this way, ICF construction is a growing trend that should be adopted by pool companies if they want to become more efficient.
Building an ICF pool requires less labor, expertise and time than a traditional concrete pool:
4. The Design Versatility of ICF Pools
ICF forms come in many shapes and sizes that you can easily cut without heavy equipment. This feature allows designers to more easily and economically include elements such as curves, arches and radiused walls compared to other pool construction methods that only accommodate uniform designs.
ICF pools offer more consistent wall finishes than standard concrete pools.
Contractors can create a smooth and 100% waterproof wall finish on the ICF pool wall by applying pool liners or plaster finishes over the pool plaster. This reduces the number of call-backs from homeowners who experience ripples in their pool liner or ineffective finishes that allow water to seep through.
It typically only takes one or two applications of the finish (about 1/2-inch thick) to complete the wall, and the resulting finish can last up to 10 years.
When you are ready to begin your pool project, choose a designer and a reliable ICF manufacturer that is familiar with ICF pool construction. It is also beneficial to have professionals walk you through all the details surrounding feasible designs, timing and installation — all features that will vary from project to project.
Once you have correctly stacked and filled the ICF blocks with concrete, per proper installation instructions, the remaining steps are comparable to typical pool constructions. It's only a matter of time before you'll be ready to add water and jump in!
