A comprehensive suite of capabilities and technologies
Abergeldie provides end to end rehabilitation and replacement services across water, wastewater and stormwater utility assets. The broad range of solutions we offer, covering mains, pipes, pits, pumps and customer service lines, enables us to confidently investigate and recommend the optimal solution for each situation.
Solutions and Technologies
Conventional construction is the original method of infrastructure installation that requires the full excavation of the scope of works.
Lift and Relay
Lift and relay utilises the conventional method whilst removing and renewing the original infrastructure in the same position.
Removal and Relay of Asbestos Water Mains
The removal and relay of Asbestos water mains utilises our Lift and Relay method. Our employees are highly trained to undertake the supervision, removal and transport of B class asbestos pipes. All these works are completed safely under EPA and WorkSafe requirements.
Pureflow is a temporary water supply system that connects seamlessly with existing water supply assets. Pureflow allows decommissioning large sections of the existing water supply, whilst maintaining a clean and reliable water source for those affected by our works. It also gives clients the option to decommission failing assets from their network whilst engineering, planning and permits are sought for renewals.
The Pureflow system consists of approximately 11 kilometres of temporary supply, road crossings and pedestrian crossings, and it is managed by our team.
Pipe bursting is a less invasive form of pipe replacement, utilising current depths and alignments. Pipe bursting greatly reduces the construction footprint, cost of reinstatement and amount of generated waste and spoil from our projects.
Pipe bursting also lessens the amount of general disruption, air pollution and noise pollution.
Directional drilling is an alternative service to pipe bursting. This solution offers many of the same benefits as pipe bursting however, taking advantage of a new alignment.
EX PVC Fold-and-Form Pipe Lining
EX is a trenchless structural pipe lining system suitable for gravity sewer and stormwater networks. Abergeldie can install this technology in circular pipes with diameters ranging from 150mm up to 300mm. PVC “folded” pipe is softened using steam, inserted into the host pipe then expanded out and “formed” within the host pipe.
CIPP (Cured in Place Pipe) Pipe Lining
CIPP is a versatile pipe lining system suitable for gravity sewer and stormwater networks. Abergeldie can install this technology in circular and non-circular pipes with equivalent diameters ranging from 100mm to 1500mm. Resin impregnated felt tube is installed and cured within the host pipe via an exothermic reaction. The curing of the liner can be via steam, water or ultraviolet light.
Spiral Wound Pipe Lining
Spiral wound liner is suitable for gravity sewer and stormwater networks. Abergeldie can install this technology in circular pipes with diameters ranging from 375mm to 900mm. A PVC strip is helically wound into the host pipe via a winding machine, converting the strip into a pipe.
Patching is a process enables localised repair of pipes in gravity sewer and stormwater networks. Abergeldie can install this technology in circular pipes with diameters ranging from 150mm up to 1000mm. A glass fibre patch impregnated with resin (typically between 400mm and 1200mm long) is installed into the pipe using an inflatable packer. The patch cures ambiently in place, treating localised cracks within the pipe.
Junction sealing is a process that goes hand in hand with pipe lining of sewer networks. Abergeldie can install this technology in circular pipes with diameters ranging from 150mm up to 300mm. A glass fibre tee impregnated with resin is installed into the pipe using an inflatable packer. The junction seal cures ambiently in place, sealing and repairing the pipe branch at the junction.
GRP (Glass Reinforced Pipe) Jacking
GRP jacking is a technique suitable for gravity sewer and stormwater networks. Abergeldie can install this technology in a variety of pipe diameters and cross-sections. Most notably, the technology enables rehabilitation of irregular pipe cross-sections that limit other solutions. The GRP is custom manufactured to the dimensions and shape required and installed in short sections using a jacking rig before the annular gap is grouted.
This is a CIPP lining process that rehabilitates dead-end pipes in sewer networks, avoiding the need to excavate to gain access to the buried end of the pipe. It is suitable for pipe diameters of 150mm with lengths up to around 25m.
Manhole and Pit Rehabilitation
Rehabilitation of sewer manholes and stormwater pits. Typically, removal or replacement of ladders, step irons, pipe droppers, etc., lid replacements or raising, protective coating such as Calcium Aluminate Cement.
CIPM (Cured in Place Manhole)
A manhole rehabilitation technology that suitable for sewer networks. An epoxy resin impregnated bag (custom manufactured to suit the manhole dimensions) is inserted and cured in place with heat, forming an impervious protective barrier that prevents further degradation of the manhole and provides additional structural strength.
Various localised excavations and repairs to support pipe network rehabilitation. Typically, pre-lining pipe repairs, raising of buried manholes or pits, etc.
Vent Shaft Rehabilitation
Rehabilitation or replacement of sewer vent shaft structures.
What Our Clients Say
The City Of Gold Coast undertakes annual Stormwater relining works as part of their ongoing Asset Management program. Over the past 6 years Abergeldie have played a major role in the rehabilitation of the city's failing stormwater drainage systems, during this time both Abergeldie's relining experts and the city's drainage technical officers have come to understanding of the requirements needed to successfully undertake the required reline works within the city's challenging tidal environment, the support and product knowledge from both teams has ensured the best fit liner is used to suit the situation which isn't always the cheapest method. It's good to know that Abergeldie will always work with their client to ensure the best and most practical reline outcome is achieved.
