Pump House was asked to support a very heavy rooftop water tank at the above project, where the tank was of considerable weight. The operating weight of the tank, (including contents - water) was nearly 13,000kg.

By utilising secondary steelwork complete with its Flexi-heavy – Flexi QUAD support frameworks, Pump House could manage the very demanding imposed loads, uniformly back down through each foot in turn.

This resulted in low foot pressures exerted onto the waterproofing system beneath, to keep within the roof insulation boards permissible compressive strength limitations.

All frameworks are fully height adjustable, via the M24 adjuster legs to compensate flat roof falls, and steelwork is hot dip galvanised for durability, to BS EN ISO 1461:2009.
