Fabrication

Polyfit’s plastic fabrication workshop is equipped to fabricate custom tanks, guards, chutes, launders, fittings and pipe spools to our client's requested specifications. Our fully equipped workshop includes a sheet butt fusion welding machine, lathe, and CNC router to provide our clients with a quality product that is cost effective.

We have experience welding and working with a variety of plastics including:

  • High Density Polyethylene (HDPE)
  • Ultra High Molecular Weight Polyethylene (UHMWPE)
  • Polypropylene (PP)
  • Polyvinyldenfluroride (PVDF)
  • Polyvinylchloride (PVC)
  • Acrylonitrile Butadiene Styrene (ABS)
  • Dual Containment Systems

Our workshop has a range of welding equipment for pipe spooling, fabricating segmented bends, tees and junctions to client specifications and drawings. We can create custom rectangular and cylindrical tanks supported by our Tank Designer 5 Software to perform engineered calculations for temperature, chemical and elemental factors for client review. With the use of our sheet butt fusion welding machine we can weld and/or roll HDPE sheet up to 40mm thick with full weld traceability.

  • For wear lining systems which are designed for flow promotion on steel surfaces due to UHMWPE’s low friction, anti stick and abrasion-resistant properties.
  • This method takes advantage of the mechanical strength of steel pipe with the abrasion, chemical and corrosion resistance of HDPE which is ideal for slurry applications.

On-site Works

Polyfit offer HDPE welding onsite using our large range of HDPE welding range with equipment available to weld pipe sizes between 25mm – 1200mm, with both high and low pressure welding machine options.


We offer total project delivery from the initial contact, full fabrication process, receipt of drawings, excavation, supply, pipe welding to delivery and on-site installation, bedding and backfill, completed with testing and commissioning.

We have experience building large bore pipelines, above and below ground, pipe spooling, civil earthworks, ring mains, fuel hubs and tailings dams.

A team of project managers with decades of combined experience in the civil, mining and construction industries are commitment to delivering their projects on time and on budget, as well as collaborating with clients to deliver the best possible outcome.

Trenching

Polyfit’s powerful Vermeer trenching machines are the ideal machines for excavating pipeline trenches, with the ability to go through most ground types with ease. We have the ability to cut trenches between 800mm up to 1000mm wide and up to 2.4m deep with our current fleet.

The use of trenching machines for pipeline excavation is an effective alternative to traditional excavation methods ensuring a flexible, reliable and cost effective solution. Our operators have extensive experience in operating and maintaining our Vermeer trenching machines and are ready to assist on your next project.

Lining

Polyfit offer geomembrane lining systems including supply and installation of dam and pond liners, turkey’s nests, landfill liners, secondary containment systems, and floating covers. We can supply and install HDPE liner, geotextiles and geosynthetic clay liner to suit project requirements.

We use a range of industry leading Demtech equipment from www.demtech.com including wedge welders, extrusion welders with spark, tensile and air vacuum testing equipment available for quality assurance.

Machine Hire

Polyfit has a fleet of fully maintained, premium quality plastic welding machinery and consumables manufactured by the world’s leading brands.

Our fleet of equipment for hire includes butt fusion welding machines, including tracked high pressure welder and low pressure welders, electrofusion machines and socket welders.
