Culverts, Drainage Work, Demolition & Land Clearing - East Coast and North East Tasmania
North East Excavations carries out drainage work, culvert installation, house demolition, rubbish removal, and land clearing across the East Coast and North East Tasmania. These are the jobs that prepare a site, manage its water, or clear the way for what comes next - and they're jobs where the right machinery and experienced operators make the difference between a clean, efficient result and a drawn-out, costly one.
We work across St Helens, Scamander, Binalong Bay, St Marys, Fingal, Scottsdale, Derby, and surrounding areas on drainage work and demolition jobs of all sizes - from a single residential driveway culvert in Scamander to multi-culvert rural drainage works across properties near Derby and Scottsdale.
Culvert Supply & Installation
Residential Driveway Culverts
Culvert supply and installation for residential driveway crossings across St Helens, Scamander, Binalong Bay, and the East Coast. We supply the culvert, excavate to the correct depth and fall, set the pipe, and backfill with drainage aggregate from St Helens Quarries. A properly installed driveway culvert manages water correctly from day one - undersized or poorly graded culverts undercut driveways and create expensive repair work that a correctly installed culvert would have prevented entirely.
Farm Track & Rural Road Crossings
Culvert installation for farm track water crossings across Fingal, St Marys, Derby, Scottsdale, and the rural East Coast and North East. Correctly sized and installed culverts on rural roads and farm tracks prevent the seasonal washout damage that turns functional tracks into ongoing maintenance problems every wet season. We advise on appropriate culvert sizing for your catchment, excavate accurately, install, and backfill with drainage aggregate.
Rural Road Water Management
Multiple culvert installations, table drain construction, and water management earthworks along rural roads and access tracks across Scottsdale, Derby, Winnaleah, and Ringarooma - where ongoing rural road drainage management is part of practical property maintenance.
Drainage Work
Residential Stormwater Drainage
Drainage work for stormwater management from buildings, driveways, and hard surfaces across St Helens, Scamander, and the coastal East Coast. Stormwater drainage work carried out correctly at construction stage protects foundations, landscaping, and paved surfaces from the water damage that makes itself known slowly and expensively over time. On the East Coast, where rainfall can be significant, properly installed stormwater drainage isn't optional.
Retaining Wall Drainage
Drainage work and drainage aggregate installation behind retaining walls across residential properties on the East Coast and North East. Water pressure buildup behind a retaining wall is the primary cause of retaining wall failure - more so than wall design or construction in many cases. We carry out the retaining wall drainage work and supply drainage aggregate through St Helens Quarries in the same job.
Agricultural & Rural Drainage
Open drain construction, subsurface drainage installation, and water table management drainage work for productive land around Fingal, St Marys, and the East Coast and North East. Properly installed agricultural drainage extends the productive season and protects pasture and cropping land from waterlogging across the region.
Site Drainage for New Builds
Drainage work carried out during site preparation, before building starts - the right time to do it, before other trades are on site. We work on new build sites across St Helens, Scamander, St Marys, Fingal, and the broader East Coast, coordinating with builders on timing to ensure drainage work is complete before construction begins.
Demolition
House Demolition
House demolition across the East Coast and North East Tasmania. Whether you're clearing an existing structure to make way for a new home in St Helens or Scamander, removing a derelict building from a rural property near Fingal or St Marys, or carrying out house demolition as part of a site redevelopment - we carry out the demolition efficiently and leave the site cleared and ready for what comes next.
Our excavators fitted with rock breakers and demolition attachments handle residential house demolition cleanly, with debris managed on site and rubbish removal organised as part of the same job where required.
Rubbish Removal
Rubbish removal and site clearance following house demolition, land clearing, or general site clean-up across the East Coast and North East. We remove demolition debris, vegetation, and construction waste - leaving the site in a condition that the next stage of work can begin from immediately. Rubbish removal is regularly carried out alongside demolition and land clearing jobs from St Helens to Derby.
Ponds & Waterscapes
Excavation for ponds, water features, and waterscapes on residential and rural properties across the East Coast and North East Tasmania. A feature pond on a residential property in St Helens or Scamander, a larger waterscape as part of a landscaping project, or a rural dam with a waterscape component near Fingal or Derby - we carry out the excavation accurately to the shape and depth required, with the finished profile ready for lining, planting, or stonework to follow.
Frequently Asked Questions
-
A standard residential driveway culvert crossing in St Helens or on the East Coast typically uses a 300mm or 375mm culvert depending on the catchment area. Rural road and farm track crossings carrying larger water flows often require 450mm or larger. Call us and describe your site - we'll give you a practical recommendation.
-
Yes. We carry out house demolition and structure demolition across St Helens, Scamander, St Marys, Fingal, and the broader East Coast and North East. Call to discuss your project and we'll advise on what's involved.
-
Yes. Rubbish removal and site clearance can be organised as part of the same job as house demolition or land clearing. Call to discuss and we'll include it in the scope.
-
A single residential driveway culvert typically takes a half to full day including excavation, installation, and backfill. Larger rural road crossings take longer. We'll give you a realistic timeframe when you call.
-
20mm drainage aggregate is the standard choice for culvert backfill and surrounds on residential crossings. Larger culvert installations in rural settings may use coarser material. We supply through St Helens Quarries - it's part of the same job.
-
If the wall is retaining soil - any wall above about 600mm in height - drainage behind it is not optional. It's what controls hydrostatic pressure during and after rain. If you're having a retaining wall built and the drainage question hasn't been raised, raise it.
-
Yes. We carry out pond and waterscape excavation on residential and rural properties across the East Coast and North East. Call to discuss the size, shape, and depth you have in mind.
