Building and Minor Civil Engineering

Minor civil engineering projects refer to smaller-scale construction or infrastructure projects that typically do not involve major structural work or extensive excavation. Some examples of minor civil engineering projects we can complete include:

  • Road and sidewalk repair: This can include fixing cracks, potholes, and other surface damage on roads, sidewalks, and other hard-surface areas.
  • Drainage and flood protection: Projects that involve installing or repairing storm water drainage systems, ditches, and retaining walls to protect against flooding.
  • Fencing and walls: Projects that involve installing or repairing fences, walls, and retaining walls to provide security, privacy, or erosion control.
  • Retaining walls: Projects that involve building walls to hold back soil or rock and prevent erosion, landslides, or settling.
  • Landscaping: installing irrigation systems and creating hard-surface areas such as patios and walkways.
    Concrete and asphalt work: Projects that involve pouring concrete for sidewalks, driveways, and other hard-surface areas, as well as repairing and resurfacing asphalt / tarmac roads and parking lots.
    Overall, minor civil engineering projects play an important role in maintaining and improving the built environment and the infrastructure that supports it. Redwood has experienced fully trained and qualified staff who have the necessary equipment and expertise to complete the work safely and efficiently.

Drainage Installations

We provide a wide range of drainage installations, including stormwater systems, wastewater management, and water quality management solutions. No matter what type of drainage system you require, we can design and install it to suit your specific needs and requirements. Our team of engineers and technicians haextensive experience designing and installing a wide variety of stormwater systems, including drainage networks, ponds, and dams. We also design and install wastewater management solutions, including water treatment plants, sand filters, and effluent ponds. For water quality management, we design and install a range of water filtration systems, including water softeners and reverse osmosis systems.


Water Supply Services

We provide a range of water supply services, including water treatment, water source selection, and pump station design. Whether you’re looking for a new water source or need to upgrade an existing water treatment system, we can help. Water treatment involves filtering and disinfecting water to remove contaminants, including sediments, salts, minerals, and microorganisms. If you need a new water treatment plant, we can assist with the design and installation of a system that meets your specific needs. For existing water treatment systems, we can provide a range of services, including pump station design and maintenance. If you are sourcing a new water source, we can help you identify the most suitable location and aid with obtaining the necessary licenses and certifications.

Drainage and Interceptor Installations

Drainage and interceptor installations refer to the process of installing and upgrading systems for the collection, treatment, and disposal of wastewater and other liquid pollutants. The process typically involves the following steps:

  • Planning and design: The first step in any drainage and interceptor installation project is to plan and design the system. This involves analysing the wastewater flows and developing a detailed plan for the collection, treatment, and disposal of the wastewater. This stage also involves identifying any potential challenges or constraints, such as site access, proximity to existing utilities, and environmental impact.
  • Excavation and preparation: The next step is to excavate and prepare the site for the installation of the drainage and interceptor systems. This may involve digging trenches or shafts, installing pipe supports, and preparing the site for the installation of the drainage pipes and interceptors.
  • Drainage pipe installation: The drainage pipes are then installed, typically using trenchless techniques, such as horizontal directional drilling or pipe jacking. The pipes are connected to the wastewater sources, such as toilets, sinks, and showers, and are routed to the interceptors.
  • Interceptor installation: The interceptors are then installed, typically in underground chambers. They are designed to capture and separate pollutants, such as oils, fats, and grease, from the wastewater, and to prevent these pollutants from entering the main sewer system.
  • Connection and testing: Once the drainage pipes and interceptors are installed, they are connected to the existing wastewater and sewer systems. The systems are then tested to ensure that they are functioning properly and that there are no leaks or blockages.
  • Backfilling and restoration: After the tests are complete, the site is backfilled and restored to its original condition. This may involve repaving, landscaping, and other surface restoration work.

Drainage and interceptor installations are critical for the effective treatment and disposal of wastewater and other pollutants. The process is carefully planned and executed to minimise disruption to the surface, to protect the environment, and to ensure the long-term performance of the systems.

Creating a New Water Supply Using No-Dig Technology

Creating a new water supply using no-dig technology involves a process that minimises the need for excavation and minimises disruption to the surface. No-dig technology involves the use of specialised equipment and techniques to install new pipes and water supply systems without the need for traditional excavation. Here is a general overview of the process of creating a new water supply using no-dig technology:

  • Planning and assessment: Before the work begins, the area is carefully assessed to determine the best location for the new water supply and to assess the existing underground infrastructure. This may involve using ground-penetrating radar, sonar equipment, or other techniques to create a detailed map of the area.
  • Trenchless drilling: The new water supply pipes are installed using trenchless drilling techniques. This involves drilling a small hole from the surface to the desired location and then pulling the new pipes through the hole. This minimises the need for excavation and reduces disruption to the surface.
  • Pipe laying: The new pipes are laid in the desired location, typically using horizontal directional drilling (HDD) or pipe jacking techniques. These techniques allow the pipes to be installed underground without the need for excavation, and they minimize disruption to the surface.
  • Connections: The new water supply is then connected to the existing network of pipes and valves, and any necessary fittings or valves are installed.
  • Testing and commissioning: After the new water supply is installed, it is tested to ensure that it is functioning properly. This may involve pressurising the pipes and carrying out water flow tests to confirm that the system is working as intended.

Overall, creating a new water supply using no-dig technology is a fast and efficient way to add new capacity to an existing water supply network. It minimises disruption to the surface and reduces the need for excavation, making it a popular choice for many communities and organisations.
