ATL have developed and extended the use of composite GRP materials to encompass virtually all of the aquarium display and industrial applications previously regarded as only suitable for concrete construction and many of the ones which do remain to this convention are now lined in GRP to deliver a fully waterproof structure.
The site time advantages of using GRP tanks as opposed to concrete are significant.
Tanks can be pre-fabricated and glazed, even decorated, off site then delivered and installed as a near finished unit, saving huge amounts of time and easing site congestion from the involvement of far fewer trades than would be the case with concrete.
