Desilting — Grease Traps & Manholes

Assess and remove accessible silt and sludge from grease traps and manholes

Silt, grit and grease in manholes, grease traps or main building drains may reduce usable drainage space and contribute to blockage or odour. We assess accessible areas and waste-handling arrangements before proposing desilting, flushing or further inspection.

Frequently Asked Questions

How is desilting different from unblocking?
Unblocking addresses an existing clog; desilting addresses deposits in accessible drain bottoms, traps and manholes. The scopes differ, and results depend on concealed sections, pipe condition and the source of deposits.
Is desilting messy — will it disrupt my business?
Desilting can involve odour, noise, wet areas and waste movement. Before booking, we discuss protection, collection, transport and possible timing for the site's access and operating hours; actual disruption depends on scope.
