Why high-pressure jetting matters

Over time, drainage systems can become restricted by grease, silt, debris, and other materials. If left untreated, this can lead to:

• Blocked drains and overflows
• Slow drainage and system back-ups
• Unpleasant odours
• Increased risk of system failure and costly repairs

Regular or reactive jetting keeps systems clear, improves performance, and reduces the likelihood of disruption.

Our equipment and approach

We use a combination of tanker-mounted and portable high-pressure jetting systems to deliver the most effective solution for each site:

• Tanker-mounted jetters – High power and capacity for large commercial and industrial applications
• Portable jetters – Ideal for confined spaces, domestic properties, and hard-to-access areas

This flexible approach allows us to respond quickly and efficiently, regardless of site constraints or job size.

Applications

High-pressure jetting is suitable for a wide range of drainage and cleaning tasks, including:

• Clearing blocked drains and pipework
• Removing grease, fat, and FOG build-up
• Eliminating silt, sludge, and debris
• Cleaning septic tanks, grease traps, and oil interceptors
• Flushing culverts and surface water systems
• Preparing drainage systems for CCTV surveys or repairs

Our equipment and experience allow us to handle both routine maintenance and more complex cleaning requirements safely and effectively.

• Routine maintenance programmes to prevent blockages
