The ISOBLOK pool system is a type of polystyrene block that is designed for quick and simple pool construction. There are several advantages in using these rather than concrete blocks or cast concrete structures. The blocks are light and therefore quicker and easier to transport and install. The isothermic properties provides two layers of insulation which will help reduce heat loss to the surrounding earth and keeping the pool warmer. Another advantage is that with this system you do not get the thermal difference at the water line that causes cracks in cement pools as the cement changes temperature at different rates. ISOBLOC are suitable for most types of pool finish and can be manufactured to any shape or design you would like.
