Sixteen years of soil mechanics for residential, commercial and infrastructure projects. Byron Bay based, working across the Northern Rivers and NSW.
Deep excavation retention, designed and supervised
From feasibility through to sign-off on site, with the analysis to back the recommendation.
A site specific drilling, insitu and laboratory testing program, and a report on what it means for your design.
Essential where the development sits on steep ground or a known landslide area.
Assessment where excavation or dewatering will expose iron sulfides to air.
We read the architectural, structural and survey drawings and build the geotechnical model from them.
Foundations, slope stabilisation, retaining walls, batters, soil nails, anchors, rock bolts and earthworks.
Footing and pier inspections, bearing capacity confirmation, level 1 supervision and rock face inspection.
Numerical modelling and the ground truth that goes with it.








We have the experience and knowledge to provide innovation solutions and expert advice on a diverse range of geotechnical complications for any civil engineering project, regardless of size and scope.OB Geotechnics · Byron Bay
