A regional road in South Australia required urgent structural repairs after a large sinkhole developed above three 1800mm culverts beneath the roadway, a key route for grain haulage.
A regional council in northern New South Wales required a comprehensive inspection and condition assessment of its stormwater network to strengthen flood mitigation planning and inform future maintenance priorities.
A tidal channel in Sydney required the removal of asbestos-contaminated sediment to restore environmental safety and site integrity. The site presented complex conditions including limited access, tidal fluctuations, and a 1.4km haul route from the entry point. TDG Environmental was engaged by the client to deliver a compliant and efficient solution for safe waste removal, stockpile management, and site rehabilitation within a restricted tidal environment.
A canal in Sydney required vegetation removal and desilting works to restore proper water flow and reduce the risk of flooding during heavy rainfall. The site presented significant access challenges, including no ramp access and extremely tight working conditions. TDG Environmental was engaged to provide a solution that would overcome these limitations while ensuring safe and efficient removal of overgrowth and built-up sediment.
A heavily overgrown canal in Western Sydney required urgent desilting and vegetation removal to restore water flow and reduce the risk of flooding. Due to the steep embankments and absence of ramp access, traditional excavation methods posed significant safety risks. TDG Environmental was engaged to deliver a safe, efficient, and non-entry solution to clear the canal and prevent future blockages.
Confined Space Risk Eliminated: All works completed using equipment, removing the need for personnel entry.
Flow Restored & Flooding Prevented: Full desilting and debris removal ensured unobstructed water movement.
Efficient, Non-Invasive Execution: Completed without ramping or major civil works, reducing time and risk on site.
TDG Environmental successfully rehabilitated the sewer pipeline, achieving a fully sealed and structurally reinforced solution. The intervention prevented potential sinkholes, safeguarded the roadway, and ensured the long-term reliability of the asset.
Enhanced Structural Durability: The CIPP patching method provided a 100-year design life, ensuring long-term pipeline integrity.
Prevention of Future Sinkholes: We eliminated any chance of a sinkhole forming, which could have compromised the road surface.
Client Satisfaction: The asset owner and client were very happy with the quality and efficiency of the work performed.
A newly placed power pole was installed through an existing asset, causing a major obstruction and presenting a potential flood risk. The issue required a rapid and comprehensive intervention to prevent further damage and ensure the continued functionality of the affected infrastructure.
A severe sewer blockage obstructed 99% of a 1075mm diameter pipe located 30 metres underground, requiring urgent and complex intervention over a 2.5-week period.
Engaged to assist in flood recovery efforts for a regional council area, we set out to clean debris from 9 x 825mm pipes, including their inlets and outlets. Services provided: Kaiser Water Recycling Unit to allow for continuous cleaning operations, despite there being no onsite water An excavator and tipper to remove excess debris Traffic control measures to safely isolate the site from vehicle traffic A locator to identify underground assets, preventing any potential damage
The project’s main goal was to conduct lateral lining installations within wastewater connections, a task requiring a high degree of expertise and precision. Our team met this challenge with remarkable proficiency, delivering outstanding results that surpassed expectations.
