Case Studies
Real-world examples of how Trenchmate solutions have been implemented in challenging projects.
Waterview Connection Project
The Challenge
The Waterview Connection project required extensive trenching in varying soil conditions with limited workspace near existing infrastructure. The project needed a solution that could adapt to changing ground conditions while maintaining the highest safety standards.
Our Solution
Trenchmate provided a custom-configured modular shield system that could be adjusted on-site to accommodate different trench depths and widths. Our engineering team designed a specialised configuration that allowed for safe installation of large-diameter stormwater pipes in confined spaces.
Results
- •Reduced excavation volume by 30% compared to traditional methods
- •Enabled safe working conditions in trenches up to 6.5 meters deep
- •Minimised disruption to surrounding infrastructure
- •Completed the trenching phase ahead of schedule
Key Features
Custom Shield Configuration
Specially designed shield system with adjustable struts to accommodate varying trench widths
On-Site Engineering Support
Trenchmate engineers provided ongoing consultation throughout the project
Rapid Deployment
Modular design allowed for quick assembly and repositioning as the project progressed
Client Testimonial
”Trenchmate's custom solution was instrumental in helping us overcome the complex challenges of the Waterview project. Their engineering expertise and flexible shield system allowed us to maintain our safety standards while working efficiently in difficult conditions.”

Coastal Pipeline Installation
The Challenge
A critical water infrastructure project required installing a large-diameter pipeline along a coastal area with unstable sandy soil and high water table. The proximity to the ocean created challenging conditions with tidal influences affecting groundwater levels.
Our Solution
Trenchmate engineered a specialised dewatering and shoring solution combining our aluminum shield system with integrated dewatering capabilities. The lightweight aluminum shields were crucial for the sensitive coastal environment, while custom-designed end plates prevented water ingress.
Results
- •Successfully maintained dry working conditions despite tidal fluctuations
- •Reduced environmental impact through minimal excavation footprint
- •Completed installation 15% faster than projected timeline
- •sero safety incidents throughout the project duration
Key Features
Lightweight Aluminum System
Reduced ground pressure in sensitive coastal soils while maintaining structural integrity
Integrated Dewatering
Custom-designed system to manage groundwater in tidal conditions
Environmentally Sensitive Design
Minimised disruption to coastal ecosystem while ensuring worker safety
Client Testimonial
”The coastal conditions presented significant challenges for our pipeline installation. Trenchmate's innovative approach to dewatering and shoring made what seemed impossible not only possible but efficient. Their aluminum shield system was the perfect solution for our environmentally sensitive site.”

Christchurch Rebuild - Underground Services Renewal
The Challenge
Following the Canterbury earthquakes, Christchurch required extensive underground infrastructure renewal in areas with unstable soil conditions and liquefaction concerns. The project involved working in densely populated urban areas with numerous existing services.
Our Solution
Trenchmate developed a specialised urban trenching solution featuring our modular manhole boxes with adjustable bracing systems. We provided a combination of standard and custom-configured shields to address the varying ground conditions across the city.
Results
- •Safely completed over 15km of service trenching in challenging post-earthquake conditions
- •Reduced vibration impact on surrounding structures through specialised installation methods
- •Maintained continuous access for residents throughout the project
- •Achieved 100% compliance with stringent post-earthquake safety regulations
Key Features
Earthquake-Specific Engineering
Shields designed to account for potential aftershocks and liquefaction sones
Urban Access Solutions
Compact shield configurations for working in confined urban spaces
Rapid Deployment System
Quick-connect components allowing for fast shield installation and removal
Client Testimonial
”The post-earthquake environment presented unprecedented challenges for underground work. Trenchmate's ability to adapt their shoring solutions to our specific needs was invaluable. Their equipment and expertise were key factors in our successful infrastructure renewal program.”
