Mainmark Sydney, North Sydney, NSW

Strong foundations start with stable ground. Mainmark specialises in ground engineering, helping homeowners, businesses and infrastructure operators address ground movement, foundation settlement and sinking concrete with confidence.

Cracked walls, uneven floors and subsiding foundations can be signs of an underlying ground problem. Our experienced team assesses each project and recommends a tailored solution to improve ground stability, strengthen support and, where appropriate, lift and relevel affected structures.

Our services include foundation repairs, resin underpinning, ground improvement, concrete slab lifting and levelling, soil stabilisation and void filling. Using specialist technologies such as Teretek® resin injection, Terefil® lightweight foamed concrete and JOG Computer-Controlled Grouting, we tackle challenges across residential, commercial, industrial, infrastructure and mining projects.

What sets Mainmark apart is our combination of technical expertise, innovative methods and a practical understanding of our customers’ needs. Our minimally invasive techniques can often reduce the need for extensive excavation, helping minimise disruption to homes, workplaces and surrounding areas.

From a settling house foundation to a large-scale ground improvement project, we focus on finding the right solution for the conditions beneath the surface. We explain the recommended approach clearly, work closely with our customers and deliver every project with care and professionalism.
