Several types of balconies are made by London Precast, depending on whether “Ordinary Reinforced Concrete” or “High Performing Concrete” has been used and whether these balconies are fitted with thermal breakers or not. Other variations in finishing may exist, depending on Architects preference.

Reinforced concrete slabs which have unsupported balconies and landings are known problem areas for thermal insulation, acoustic transmission and corrosion. Cold bridging leads to condensation and potential development of damp internal corners and mould. Traditional rigid construction gives rise to further problems, for example stresses resulting from temperature fluctuations and signs of fatigue in reinforcing bars. These problems and consequential damage are what London Precast Balcony systems seeks to solve.

Installation of London Precast balconies is quite simple. The balconies are propped according to specification details contained in the drawings, or more commonly 2 number props – usually supplied by the contractor - for every 3m. The props are left in place for 21 days - except where a specific instruction by the engineer overrides this requirement. The props are removed from place after the expiration of the period stated thus or in exceptional situations as may be deemed right by London Precast. Installation takes account of initial and final settlements.
