A newly developed industrial park in Australia required an integrated underground infrastructure system, including stormwater drainage and electrical cable protection. The project emphasized durability, efficient installation, and long service life under varying soil and load conditions.
Location:Australia
Project Period: 2023
EXLON PIPE supplied a combination of HDPE Double Wall Corrugated (DWC) Pipes for drainage and PVC electrical conduits for cable protection, forming a coordinated underground piping solution.
Products were manufactured to meet project-specific specifications, with attention to ring stiffness, impact resistance, and installation compatibility with local construction practices. Packaging and labeling were customized to support on-site handling and identification.
Project Value
- The DWC drainage pipes provided structural strength and smooth internal flow performance, helping ensure reliable stormwater discharge.
- PVC conduits offered effective mechanical and electrical protection for underground cables, improving long-term maintenance safety.
- Coordinated logistics and stable supply helped the contractor maintain progress across multiple construction zones without material delays.
Site conditions varied from soft infill to well-compacted subgrade and required different ring-stiffness ratings. EXLON recommended SN8-class DWC for road-crossing sections and SN4-class where lower loading applied, balancing cost and structural performance. For conduit runs under planned paved areas, we supplied rigid PVC conduits with thicker walls to improve impact resistance during backfill and compaction. EXLON also provided installation notes on bedding, sidefill, and jointing to reduce rework and ensure design stiffness in differing soil conditions.
To simplify on-site handling, pipe bundles were labeled by lot and length, and conduits were delivered with pre-marked pull points. EXLON offered a short virtual briefing with the site engineering team to review installation sequencing and to confirm jointing tolerances and cover depths; this reduced on-site queries and clarified responsibility boundaries between subcontractors.
Given the project’s phased schedule and local site constraints, EXLON coordinated flexible delivery windows and used reinforced skids for longer lengths to prevent deformation during transport. Clear packing lists and advance notice of arrival times helped the contractor organize crane and lifting resources efficiently.
The integrated supply of DWC drainage and PVC conduit allowed the client to implement coordinated underground services with fewer interface issues between trades. The selected pipe stiffness and conduits met the park’s durability expectations while keeping installation efficient. The contractor noted fewer on-site material queries and steady progress through each construction stage, supporting the park’s overall schedule and commissioning targets.
