Retaining, Shoring and Structural Works

All Civil Solutions Group delivers retaining, shoring, underpinning and structural ground support works across Sydney and NSW. As an experienced retaining wall, piling, underpinning and ground support contractor, we provide engineered solutions for excavation support, slope stabilisation, foundation systems, structural strengthening and infrastructure protection.

Our capability spans permanent and temporary retention systems, deep foundation piling, underpinning of buildings and structures, shotcrete support systems, soil nailing and structural reinforced concrete construction. We work closely with geotechnical engineers, structural designers and councils to deliver compliant, durable and performance-driven outcomes aligned with Australian Standards and project specifications.

These works are critical for early works packages, landslip remediation, building stabilisation, road widening, bridge approaches, infrastructure upgrades and construction within constrained urban and transport environments.
