Swimming Pool Construction | Sussex Leisure Centre
Leca® LWA has been used in the construction of a Sussex swimming pool and leisure centre to overcome poor ground conditions and essentially reduce the extent of soil stabilisation.
The swimming pool was constructed on recovered land close to sea level. The soil is an unstable mixture of sand and flint and the water table is, in places, only inches below the surface. The actual swimming pool was built on the surface rather than into it, as is common practice. While this eliminated the problem of building the pool into the water table, it also produced the problem of building the pool surrounds to level without the use of heavy structures.
Soil stabilisation techniques had been employed on parts of the site, notably the car park, but care had to be taken to keep costs as low as possible since the pool had been financed from a variety of public sources and there was no
flexibility in the budget.
It was therefore proposed to use Leca® LWA as a very low weight in-fill to eliminate the need for soil stabilisation under the pool building.
1720m3 of Leca® LWA 4-10r/c was tipped on site and tracked in place, contained within block walling, bringing the pool surrounds to level while overcoming the poor ground conditions and restrictive budget.
