Civil Plumbing & Drainage Works


Practical Civil Plumbing for Busy Sites
Surface pooling or water tracking under slabs often starts as an unseen drainage fault. We begin by mapping site falls and reviewing engineering drawings so the water moves where it should, away from buildings and paved areas.
At LJB Plumbing and Civil, we coordinate with engineers and builders early to set pipe grades, choose durable materials and position pits and access points for future maintenance. This front-loaded care reduces on-site changes later and keeps construction programs tidy.
What we bring to site:
- Experience with large-diameter pipework and pit design.
- Ability to read hydraulic drawings and confirm levels on site.
- Staged installation that fits the builder’s program.
Civil Drainage Installed With Precision
We install stormwater mains, sewer junctions and heavy downpipes using tested methods and measurable checks. Our crew prepares trenches, sets bedding, lays and grades pipes, then performs pressure and flow tests before backfill. Where required, we provide as-constructed records and CCTV validation so authorities accept the works without delay. The outcome is a robust drainage network that limits erosion, protects slabs and reduces ongoing maintenance.
Client benefits include:
- Fewer site interruptions during handover.
- Precise connection to council mains.
- Reduced repair frequency over the asset life.
- Clear documentation for compliance and future works.
If your project needs durable in-ground plumbing that integrates with the build program, contact us to arrange a site review and timeline.
