Concrete grease traps have long been the industry standard, especially in older commercial kitchens, shopping centres, and food courts. But over time, these traps begin to deteriorate.

Exposure to fats, oils, grease (FOG), acidic waste, and detergents causes:

  • Internal corrosion
  • Hairline cracks and structural failures
  • Leaks, odour issues, and non-compliance

And that’s just the beginning. In high-traffic commercial settings, downtime for repairs can mean lost revenue and frustrated tenants.

💡 The Plastic Solution: HDPE Relining

At Hercules Plastics, we offer a smarter, faster solution: custom-fabricated HDPE liners that reline existing grease traps without the need for demolition or excavation.

HDPE (High Density Polyethylene) is:

  • ✅ Corrosion and chemical resistant
  • ✅ Fully sealed with gas-tight access lids
  • ✅ Smooth-walled for easier cleaning and less build-up
  • ✅ Light but strong — quick to install

We fabricate each liner to suit your site’s exact measurements, ensuring a snug, secure fit that restores functionality and extends the life of your grease trap.
