Silt removal

Silt consists of fine particles of sand, soil, and debris that gradually accumulate in drains, gullies, channels, and silt traps, reducing flow and increasing the risk of blockages or flooding.

Our silt removal services include:

• High-capacity tanker extraction for larger drainage systems
• Manual removal in confined or hard-to-reach areas
• Emptying silt traps, gully pits, drainage channels, and soakaways
• Thorough cleaning to restore full drainage capacity
• Safe disposal of all collected material in line with environmental regulations

By removing silt efficiently, we restore the performance of drainage systems and reduce maintenance issues.

Sludge removal

Sludge is the thicker, semi-solid waste that collects in septic tanks, sewage treatment plants, storage tanks, sludge rooms, and other containment systems. Improperly managed sludge can cause blockages, system failures, and environmental hazards.

Shanahan Contracting Ltd provides:

• High-capacity tanker extraction of sludge from tanks and treatment systems
• Manual cleaning of sludge rooms, interceptors, and industrial process tanks
• Safe transport and licensed disposal of all sludge
• Full restoration of systems to operational, hygienic, and compliant condition

Our combined approach of tanker power and expert manual handling ensures sludge is removed thoroughly, safely, and efficiently.
