Underground car parks & Basements
More cost-effective, faster execution
Hot rolled steel sheet pile sections are the ideal material for constructing retaining walls of underground car parks (UCP) and basements.
Main advantages are:
- more cost-effective;
- faster execution;
- vertical load bearing capacity, sheet piles can transfer significant vertical loads from the structure above ground to the soil (works simultaneously as a retaining wall and as a foundation element);
- watertight walls and connections with bottom slabs.
The Sustainable Solution for UCP Construction
ArcelorMittal mandated in 2018 the renown Dutch consulting engineering firm Royal Haskoning DHV to analyse the strengths and weaknesses of the steel sheet pile solution in The Netherlands. To summarize the Dutch study, based on typical Dutch soil conditions and installation techniques, UCP up to 4 levels below ground built with steel sheet piles are the most sustainable solution: up to 50% more cost-efficient than alternative solutions, installation up to 2 times faster, and durable solution.
The fact that steel sheet piles can be driven tight against the boundaries of the site, and that the wall itself has minimum thickness, means that the surface area available for cars is maximised and hence, the cost per bay is minimised.
