This is a quick look at hand piling and piering in to sand to retain existing buildings or in footings.Once piles are complete they form a contiguous wall which will support the area for excavation safely.Hand pile diameter are usually 300mm up to 600 diameter and also have reo bars concreted in as per engineering specifications.There are minimum gaps between piles unlike machine piling thus spraying concrete is not necessary unless a clean flat finish is needed reducing cost. Capping beams and or steel bracing can also help support deep excavation.This quick look gives you an idea of the labour intensive process involved although work is normally completed between 3 and 6 working days unlike machine piling which can take weeks and months.For Sydney Australia enquires (sand areas i.e. North Shore,Bondi through to Paddington,Bellevue Hill,Bondi,Clovelly etc even Alexandria and also Cronulla and Brighton) Please email bjenterprise_aust@yahoo.com.au . bracing, Construction, excavation, footings, Handpiling, Piering, Piling, Retaining, sand, Shoring, Steelfixing, underpinning
