Pipe Bursting
A widely proven methodology for replacing an existing asset with a new High Density Polyethylene Pipe (HDPE).
Pipe bursting is a highly efficient and low impact methodology of replacing a deteriorated pipe with a new asset. The process involves excavating a single point at either end of the asset requiring replacement then continuing to utilise a Pneumatic or Static bursting head to break or split the existing asset while simultaneously pulling in the new pipe.
This methodology is ideal for upsizing pipelines to increase flow capacity or for assets that are unable to be excavated to replace.
The benefits of Pipe Bursting if the vastly reduced impact to the environment and cost associated with disposal and importing of fill.
Suitable application areas:
- Water
- Sewer
- Stormwater
Slip Lining
One of the most versatile trenchless rehabilitation techniques – Slip lining is an efficient solution for rehabilitating an asset where flow capacity can be sacrificed for structural integrity.
Slip lining is a method designed to insert a new, smaller diameter pipe within an existing larger deteriorated asset. In most cases, this process involves little to no excavation requirements making this an efficient and cost-effective solution for extending the lifespan of the asset in a timely manner.
Dependent on the application, size and access – Slip lining typically uses a High-Density Polyethylene pipe (HDPE) or in larger diameters a Glass Reinforced Plastic pipe (GRP).
The anulus between the new and existing pipe is commonly grout filled to aid satisfaction of the design requirements and securing the asset in place.
Suitable application areas:
- Water
- Sewer
- Stormwater
CCTV Inspection
Typically, the very first step in understanding a pipes rehabilitation requirement or determining the next maintenance activity is to undertake a CCTV Inspection of your asset(s).
Infrastructure Renewal Services can provide CCTV Inspection across all application areas to provide Condition Assessment and Serviceability Assessment on a planned or reactive basis.
With modern CCTV Capabilities, our trained operators can inspect a range of diameter pipelines from DN100mm up to DN2200mm and up to 300m in length from one access point.
Utilising WINCAN VX Inspection Reporting software, IRS can provide all clients with remote access online viewing of completed works coupled with deliverables in Geographic Information System (GIS) format.
Suitable application areas:
- Water
- Sewer
- Stormwater
Patch Lining
Where your asset requires rehabilitation in a specific location only, Patch Lining is the most viable solution for reinstating an asset’s structural and flow capacity without the need to rehabilitating the entire pipe.
Utilising our modern CCTV units, IRS operators are able to pinpoint the exact location of each defect to then install Patch Lining repairs through existing access points.
The method of Patch Lining involves use of resin impregnated fibre glass matting that is installed in place, inflated with air pressure and then is cured in place.
Being a structural repair method compliant to the Australian Standard 2566.1, Patch Lining is one of the most efficient, cost effective and suitable methodologies for rehabilitating sections of assets with minimal downtime.
IRS crews are trained and competent installers of the Patch Lining methodology and can install repairs ranging from DN100 – DN1500 in typically 600mm or 1200mm lengths.
Dependent on the application and project specifics – alternative shapes, lengths and sizes can be achieved.
Suitable application areas:
• Sewer (gravity)
• Stormwater
Structural Pipe Lining – Tight-Fit HDPE
When the structural integrity of your asset is critical but have contributing factors of the project that leaves you with costly or timely implications, Structural Pipe Lining is able to provide you with a structural full asset rehabilitation solution that can extend the service life of your asset all while avoiding the project complexities.
Tight-Fit HDPE Lining or better known as Pressure Lining is the most proven method for rehabilitation of pressure assets.
Where the asset requires the maximum internal diameter for flow capacity but for other factors cannot be excavated or burst (for example) then Pressure Lining is a quality and cost-effective solution for achieving the outcome required.
Using a High-Density Polyethylene (HDPE) pipe, the new pipe is drawn into the existing pipe through a die to significantly reduce its diameter. Once reduced, the HDPE pipe is then continued to be pulled into the existing asset (like the Slip Lining process). Upon entry into the receiving point, the tension is released off the pipe and the stored energy in the pipe causes the material to revert diametrically which creates a tight fit against the existing host pipe.
Suitable application areas:
- Water
- Sewer
Structural Pipe Lining – UV CIPP
UV CIPP offers an innovative trenchless technology to cure in place a bespoke made resin impregnated fibre glass sleeve. The material is made to required length, diameter and thickness to match design requirements while providing increased hydraulic capacity from its smooth walled finish.
This seamless pipe holds no reliance on the existing asset is compliant to the Australian Standard 2566.1.
Sizes ranging from DN150 up to DN2000 and in multiple shape profiles.
Suitable application areas:
- Water
- Sewer
- Stormwater
Open Trench –
Installation / Replacement
Where feasible, the most widely used method for installation or replacement of new pipelines is Open Trenching.
Not a trenchless technique, but throughout IRS’s business tenure we have developed our capabilities in the management and delivery of open trench projects with all compliance considerations. IRS can provide installation of new pipelines that are specification compliant and can manage all necessary site safety controls such as Shoring, de watering and Road plates (for example).
Our crews are qualified and trained for works in the following application areas of the industry:
• Water
• Sewer (pressure & gravity)
• Storm water
• Pits, access points and headwalls
IRS also offers a wide range of general civil works, including but not limited to:
• Civil contracting,
• Earthmoving,
• Pit and shaft excavation,
• Detailed excavation,
• Backfill and Compaction
Civil Repair & Maintenance
Through our experience working with some of Australia’s largest water and road authorities, IRS understands the criticality in responsiveness to maintenance and more specifically Civil Repairs requests
Whether the activity be of a trenchless nature or not, IRS crews can undertake the following (but not limited to) services in response to your specific requirements:
• Drain Cleaning,
• Non-Destructive Digging (NDD)
• Localised excavate and replacement,
• Exposing and raising of access chambers/pits,
• Cast in situ access chamber/pit construction,
• Access chamber/ pit modification works,
• Installation of headwalls including flow devices,
• Large diameter cast in situ lining (Culverts),
• Large diameter internal joint sealing,
• Pipe grouting (decommissioning).
By providing regular scheduled maintenance activities across critical assets such as roads, bridges and utilities, IRS can provide high-quality services tailored to your specific needs. Engaging with IRS are a trusted partner will provide you with reliable performance and cost-effective solutions across the term of your maintenance contract.
Suitable application areas:
• Water
• Sewer
• Storm water
Domestic & Commercial Solutions
To this day, IRS has adopted many trenchless (and conventional) repair methodologies that can be used not only in large(er) assets but also in Domestic, commercial and industrial plumbing.
Typically, more plumbing issues are associated near conflicting structures such as driveways, house extensions or existing trees for example. IRS offers our services to these trouble assets to ensure that rehabilitation can be achieved with as minimal disruption or impact as possible to your service and surrounding environment.
By rehabilitating your assets, this could save you countless time and money over the years being caused by repetitive issues and defects.
Service provisions for Domestic, Commercial and Industrial Plumbing:
• Pipe bursting,
• CCTV Inspection,
• Patch Lining,
• Pipe Relining,
• Maintenance & Civil Repair
