The reinforcement of a concrete structure is achieved by placing steel bars centrally in the concrete walls and floor. A typical 9 metre domestic pool will have more than a tonne of12mm deformed steel bar.
It is cut, bent and tied both ways to create an oversized mesh framework which will precisely reflect the shape of the pool. “ Steel fixing” is an art of its own. On completion of the steel work within the excavation, you almost feel that it’s a pity that it will be lost when covered with concrete.
Pre-plumbing is the installation of specialised fittings such as skimmers, main drains, spa jets, pool returns and light buckets, all of which are precisely positioned and secured to the steel. The pipework that will connect these items to the pool’s filtration unit are run behind the steel and out of the pool.
