Propump Engineering, the UK’s first foamed concrete specialists, has used a fibre-reinforced foamed concrete to provide a lightweight, but exceptionally strong, base for the newly-refurbished staff car park at Bremen Airport, Germany.
Propump travelled to Germany to supply and install some 560m3 of its 600kg/m3 foamed concrete in just two working days, delivering a safe and welcoming parking facility for more than 400 employees based at the airport.
Specified for its lightweight grade and proven performance, foamed concrete from Propump provided the client with a fast and easy installation. By using a similar density concrete to the contaminate substrate, this allowed excavation to be kept to a minimum and created a balanced foundation onto which the car park’s hardwearing surface would then be applied.
Traditionally, Propump supplies base grout and foam to site before combining them to create the foamed concrete screed. As the German client wanted the base mixed on-site with one of its own mobile concrete batching units, Propump had to alter its IFCS – a processing and pumping system contained on a 7.5t lorry chassis – to ensure the base materials could be processed successfully.
For additional flexural strength and to help prevent crack formation while the new concrete slab cured, Propump added polypropylene fibres into the mix. Added during the batching process, thousands of individual fibres are then distributed throughout the concrete to create a matrix-like structure that offers long-term durability and toughness.
Bremen Airport offers 100 flights a day, with 2.5 million passengers flying to 40 destinations worldwide every year. Thanks to Propump Engineering, the airport’s employees can rest assured that every time they use the staff car park, they are safely driving over 560m3 of high quality concrete from the UK’s number one foamed concrete specialists.« Foamed concrete versus polystyrene blocks – September 2011
