Prefab, fibreglass or concrete: which pool suits you
Each technology has its place. We build pools with steel walls and a membrane because we believe that, for most private pools, it is the most balanced solution. Here is a fair comparison.
A concrete pool gives complete freedom of shape but takes a long time and needs waterproofing. A fibreglass pool arrives ready in one piece, but in limited sizes and with difficult transport. A steel-wall prefab pool combines a fast build, free dimensions and easy transport.

When concrete is better
When you want a free, curved shape, when the pool is very large or very deep, or when it is part of a bigger concrete project. In those cases we will tell you so.
When fibreglass
When you find a ready-made mould you like, and the lorry with its crane can reach the spot. On narrow lanes and islands that is often impossible.
Why we choose prefab
Because it gives you a pool in the dimensions you want, quickly, with no heavy machinery in the street and watertightness that does not depend on render. And because in 15 or 20 years the refresh is a new membrane, not a rebuild. See the walls and the process.
