What we do
Stormwater drainage, large-diameter pipe laying, deep excavation and civil works. We work for civil contractors, builders and developers across greater Sydney.
Stormwater drainage
Stormwater drainage for subdivisions, roads and civil projects. We trench, lay pipe, set pits and backfill. Work is set out to the engineer's design and levels.
Typical scope
- Trenching to design levels
- Pipe laying, bedding and jointing
- Connections to existing stormwater networks
- Backfill and compaction
- Pipe sizes from 150 mm plastic up to 2100 mm concrete pipe
Large-diameter pipe laying
RCP (reinforced concrete pipe) laid to line and level. We lay single, twin and triple runs, and box culverts. Our crew has laid big pipe for years and our excavators are sized to lift it.
Typical scope
- RCP up to 2100 mm diameter
- Twin and triple RCP runs
- Large precast structures: headwalls, large pits, culverts, water storage devices and GPTs (gross pollutant traps)
- Laser-set levels and grades
- Bedding, laying and jointing
Deep excavation
Deep trenches and excavations with benching and shoring. Each job is planned under a SWMS (safe work method statements) before we dig. We run hydraulic hammers for hard ground.
Typical scope
- Multiple deep excavations completed using open-cut benching and/or shoring protection
- Benching and battering
- Rock breaking with hammer
- Spoil handling and stockpiling
Pits, headwalls and GPTs
Pits, headwalls and GPTs installed to the engineer's design. We set them to level and connect the pipe.
Typical scope
- We install precast pits, and prepare cast-in-situ pits (excavation, base and set-out) ready for the concreter's steel, formwork and pour
- Headwalls at pipe outlets
- GPTs and other large precast structures
- Pipe connections into pits
Civil works
General civil works with our own plant and crew. We can take on excavation and site work around the drainage package.
Typical scope
- Bulk and detailed excavation
- Site preparation
- Backfill, compaction and reinstatement
- Other civil construction work – with road building and full civil project experience from Brendon's foreman and project manager years at TRN, we can support wider civil scopes
Machine hire with operator
Excavators from 14 to 37 tonnes (Volvo and Sumitomo), plus skid steers, hired with an experienced operator.
Typical scope
- Hire hourly, daily or weekly by arrangement
- Multiple attachments: buckets, compaction wheels, hydraulic hammers and more
- Transport to site arranged
