TJK CIVIL

With over 10 years in the communications industry, including major NBN infrastructure projects, TJK Civil brings industrial-grade professional standards to every job site. We understand that underground infrastructure requires more than just digging a hole—it requires precision, adherence to utility codes, and the protection of existing assets.

Whether you need complex network infrastructure for a commercial project or a new NBN lead-in trench for your home, we have the specialized machinery and technical experience to get it done right the first time.

• Pit & Pipe Installation: Complete infrastructure installation for telecommunications and electrical networks.
• NBN Lead-ins: Trenching and conduit installation from the street connection point to your dwelling.
• Asset Proving (Potholing): Using Vacuum Excavation to safely expose and verify existing underground services before digging.
• Compliance: All work executed to strict carrier and civil construction standards.

We specialize in tight-access earthworks, utilizing compact, high-power machinery (Kanga Mini Loader) that can fit through standard pedestrian gates without sacrificing performance. This allows us to bring professional excavation power into backyards and confined spaces where larger machines cannot go.

Whether you need trenching for new power and water lines, soil removal for landscaping, or precision post-hole drilling, we get the job done with minimal disruption to your property.

• Micro-Trenching: 150mm wide trenching perfect for irrigation, electrical conduits, and NBN lead-ins.
• Side-Access Clearing: Moving soil, rock, and mulch through gates as narrow as 1000mm.
• Post & Pier Holes: Precision drilling for fences, decks, and retaining walls in confined areas.

A gravel driveway is a cost-effective and practical solution for Surf Coast and Bellarine properties, but it requires the right foundation to last. We apply civil construction principles to residential driveways, ensuring proper drainage, correct material depth, and a solid base that withstands the elements.

Whether you need a brand-new "site cut" and installation for a new build, or your existing driveway is full of potholes and needs a professional resurface, our Mustang Skid Steer and operators deliver a smooth, long-lasting finish.

• New Installations: Full site cuts, sub-base compaction, and crushed rock spreading.
• Resurfacing & Repairs: Grading uneven surfaces, filling potholes, and topping up existing gravel.
• Drainage Solutions: Correcting driveway camber to prevent water pooling and erosion.
• Material Spreading: Efficient distribution of toppings, crushed rock, or recycled concrete.

Underground assets are easily damaged by traditional mechanical digging. We utilize specialized Vacuum Excavation (NDD) technology to safely expose underground utilities such as power, gas, and telecommunications cables without the risk of strikes.

With our purpose-built vac truck, we support electricians, plumbers, and civil contractors who need to "pothole" or verify assets before construction begins. It is the safest, cleanest, and most precise method for digging around critical infrastructure.

• Asset proving and service location (potholing).
• Excavating around tree roots to preserve vegetation.
• Cleaning out pits, blocked drains, and conduits.
• Digging in areas with zero tolerance for damage.

Need to run a new water pipe, power cable, or NBN conduit but don't want to cut up your expensive concrete driveway? We offer professional trenchless installation using Grundomat impact moling technology.

This specialized pneumatic tool allows us to bore horizontally underneath driveways, footpaths, roads, and established landscapes with high precision. It is the smartest, cleanest way to retrofit services to your property without the mess, disruption, or cost of resurfacing concrete.

• Driveway Crossings: Install services under concrete or paved driveways without cutting the surface.
• Garden Preservation: Run pipes under established lawns, retaining walls, or garden beds without trenching.
• Utility Installation: Ideal for water, gas, electricity, and telecommunications conduits.
• Cost Effective: Eliminates the expensive need for concrete cutting, removal, and re-concreting.

Whether you are building a new fence, a backyard deck, or a retaining wall, the structural integrity of your project starts with the footings. We offer professional auger drilling services capable of penetrating tough Surf Coast clay and rock.

Using our maneuverable Kanga loader or Mustang Skid Steer, we can drill precise, deep, and clean holes in locations that larger drilling rigs simply cannot reach.

• Fencing: Timber and Colorbond fence post holes.
• Construction: Pier holes for decking, pergolas, and extensions.
• Retaining Walls: Deep drilling for sleeper heavy-duty supports.
• Planting: Large-scale hole preparation for mature tree planting.
