Underground infrastructure is a critical part of any development or civil project. Hammond Civil provides complete pipeworks and trenching services across Coffs Harbour, delivering systems that are properly designed, accurately installed, and fully compliant with Australian Standards. With decades of experience and a strong focus on regulatory compliance, we manage the full process in-house. This includes planning, excavation, bedding, installation, backfilling, testing, and final handover. If your project requires reliable pipeworks and trenching in Coffs Harbour, we are available to review your scope and provide a clear, cost-effective delivery plan.
Hammond Civil delivers pipeworks and trenching across subdivisions, infrastructure upgrades, commercial developments, and utility projects. Our services cover sewer and stormwater systems, rising mains, service conduits, and trenching for communications or power installations.
All projects are managed by our in-house team, using modern machinery and experienced operators. This includes trenchers, excavators, compactors, and laser-guided equipment to achieve precise installation outcomes. We tailor our delivery approach based on site access, soil conditions, and surrounding infrastructure to minimise disruption and meet project timeframes.
Pipeworks refers to the construction and installation of below-ground piping systems that carry water, wastewater, stormwater, or utilities. These systems are designed to operate under specific gradients, loads, and environmental conditions, and must be installed with precision to ensure long-term performance.
The process includes layout planning, trenching, pipe placement, and integration with pits, manholes, and other infrastructure. Material selection depends on flow requirements and structural conditions and often includes PVC, concrete, ductile iron, or polyethylene. Every system must be sealed correctly, bedded on suitable materials, and tested before use.
Trenching is the excavation of ground to allow pipes to be installed at the correct depth, alignment, and grade. It provides the necessary space to place and secure pipe systems while also allowing for proper bedding, backfill, and compaction.
Trenching must be carried out in a controlled and accurate manner to prevent future issues such as subsidence, misalignment, or system failure. In Coffs Harbour, trenching must comply with local council trench profiles and infrastructure standards, including correct depth, separation from other services, and suitable backfill materials. Hammond Civil applies approved trenching methods suited to the soil and groundwater conditions found across the Mid North Coast.
At Hammond Civil, we manage all stages of pipe installation using a structured and practical approach. This begins with site set-out and trench excavation, shaped to match design specifications. Bedding material is placed and compacted to support the pipe and reduce settlement over time.
Once pipes are laid and joined, backfilling begins in controlled layers with consistent compaction. This ensures the system is protected from movement or external loads. Every section of pipework is tested in line with its purpose. For pressure pipes, hydrostatic testing may be required. For gravity systems, air testing and level checks are completed prior to inspection and sign-off.
We also manage tie-ins to existing infrastructure and provide construction documentation to support council approval or engineering certification.
Our pipeworks and trenching activities are delivered under strict safety protocols and quality assurance procedures. This includes utility locating before excavation, application of trench support systems when required, and safe operation of plant and equipment.
We follow all local council specifications for trench dimensions, bedding classes, compaction requirements, and pipe installation methods. Quality control is maintained through onsite inspections, compaction testing, and pipe alignment checks at each stage of the job.
Documentation for each project is prepared in accordance with council or engineering requirements to support final certification.
We are a family-owned civil construction business with a long history of delivering underground infrastructure across the Mid North Coast. Since 1988, we have supported both public and private sector clients with reliable, outcome-focused delivery and detailed project coordination.
Our clients value having a single, experienced contractor managing trenching and pipe installation. This reduces complexity and improves efficiency. Our ability to meet compliance requirements and deliver consistent workmanship has made us a trusted choice for developers, engineers, and local authorities.
