Culverts, Drainage & Trenches Whangarei & Northland
Effective Water Management Solutions for Rural and Lifestyle Blocks
We install culverts, dig trenches, and build drainage systems that manage water properly, preventing erosion, flooding, and infrastructure damage.
Uncontrolled water is one of the biggest causes of damage to tracks, fence lines, tank sites, and yards. We assess your site, mark out fall, and use the right machinery for clean, controlled trenching. For culverts, we install pipe or box sections with firm bedding, cover, and erosion control in mind. From a basic roadside crossing to a network of paddock trenches, we make sure water moves away from high-use areas and doesn't cause damage down the line.
We provide a full range of water management services for rural sites:
Culvert Installation – Roadside, raceway, and track crossings using pipe or precast culvert sections, properly bedded and backfilled
Drainage Channels – Open or piped systems to redirect surface or groundwater away from driveways, buildings, or yards
Soak Trenches & French Drains – Gravel-filled trenches for managing slow-draining or heavy soils
Effluent & Greywater Trenches – Trenching and backfilling for on-site water dispersal
Trenching for Services – Neat, level trenches for water pipes, power cables, or irrigation lines
Trackside Swales – Shallow channels beside tracks or roads to carry away runoff and reduce washouts
Washout Repairs – Fixing damaged areas caused by stormwater or blocked drains
We also carry out site levelling, backfilling, and compaction, ensuring your drainage setup functions properly and doesn’t create new problems.
