The advantages of polystyrene pool blocks
Lightweight and easy to install
Easy to cut and handle, without complex tools.
Speed and efficiency on site
Quick installation thanks to interlocking EPS blocks.
Thermal insulation and energy savings
Reduced heat loss and heating costs.
Strength and load-bearing capacity
Guaranteed stability during concrete pouring and over the long term.
Swimming pools: why choose EPS blocks?
Expanded polystyrene (EPS) blocks offer optimum thermal insulation for masonry pools. Lightweight, easy to install and resistant, they limit heat loss and optimize energy consumption. In compliance with standard NF EN 17645, these blocks meet the requirements of manufacturers and distributors wishing to offer high-performance, durable and economical solutions.
PSE blocks: quick and easy installation
Thanks to their light weight and interlocking technology, EPS blocks simplify pool construction. No heavy equipment is required for installation, saving time and reducing labor costs. Ideal for both new-build and renovation projects, these blocks can be installed quickly and efficiently, without compromising the strength of the pool.
High-performance thermal insulation
EPS has excellent insulating properties that reduce heat loss through the walls and bottom of the pool. By maintaining a stable temperature, it limits heating requirements and improves user comfort. This thermal insulation also helps to reduce energy costs, while complying with the regulatory requirements of the in-ground pool market.
Pool blocks in EPS: economy and durability
EPS blocks help reduce pool construction and operating costs. Thanks to their ease of installation, they shorten construction times, optimizing project profitability. Their durability and load-bearing capacity ensure long-term structural reliability. What's more, these blocks are recyclable, contributing to a more environmentally-friendly approach.
EPS formwork blocks: guaranteed strength
Despite their light weight, EPS blocks offer excellent compressive strength. Once filled with concrete, they guarantee a stable, durable structure capable of withstanding the stresses of the pool. Their design ensures safe concrete pouring and perfect durability, meeting manufacturers' and distributors' expectations in terms of quality and reliability.
