G4 Civils delivers three core civil engineering disciplines — all underpinned by the same commitment to quality, safety, and transformation.
G4 Civils executes bulk earthworks for road infrastructure, solar projects, reservoir construction, and land rehabilitation across South Africa.
We have completed earthworks for projects including the Zeerust Solar Field and substation for Istoguard, the Rand Water Rustenburg Reservoir access roads, and multiple bulk cut-and-fill operations on the N4 national route.
G4 Civils has an extensive track record in road construction for SANRAL, Bakwena Platinum Corridor, JRA, and provincial departments of roads and transport. From gravel road upgrades to multi-lane national route rehabilitation.
Our road works include bridge and culvert upgrades, toll plaza lane expansions, filling station ramp construction, and pavement rehabilitation on high-traffic national routes.
G4 Civils holds long-term Routine Road Maintenance contracts for national and provincial roads — ensuring safe, serviceable roads year-round across multiple provinces.
