Site investigation in Bunbury addresses the region’s Bassendean sands, Tamala Limestone, and estuarine clays, which directly shape foundation risks and earthwork strategies. Our approach follows AS 1726 for geotechnical site investigations, combining field logging with targeted in-situ testing. Early-stage programs often begin with an exploratory test pit to visually assess fill, root zones, and shallow water tables, delivering immediate stratigraphic insight across residential and commercial lots.
For structural design, we pair pit observations with standard penetration test (SPT) profiling to quantify relative density and strength in deeper sands and weak limestone. This integrated method supports footings, retaining walls, and pavement subgrades in subdivisions, industrial sheds, and coastal developments. A well-scoped investigation reduces geotechnical uncertainty and underpins compliant, cost-effective construction across the Greater Bunbury area.
