Our comprehensive range of services includes high-pressure water jetting, automated non-man entry tank cleaning, drain cleaning, CCTV surveys and ultra-high-pressure abrasive cutting, helping clients reduce downtime, improve productivity and maintain critical assets.
Our high-pressure and ultra-high-pressure (UHP) water jetting systems are suitable for a variety of industrial cleaning and maintenance projects, including:
Storage tank cleaning
Process vessel cleaning
Heat exchanger cleaning
Condenser cleaning
Economiser cleaning
Tube bundle cleaning
Pipework descaling
Drain and sewer cleaning
Surface preparation
Concrete hydrodemolition
UHP abrasive cutting
All work is performed in accordance with strict health, safety and environmental standards, ensuring the highest levels of performance and compliance on every project.
Denholm Environmental's automated non-man entry jetting systems provide a safer and more efficient alternative to conventional confined-space tank cleaning.
Using advanced rotating 3D jetting heads, every internal surface of a vessel can be cleaned without requiring personnel to enter the confined space. This significantly reduces risk exposure while improving cleaning performance and reducing shutdown durations.
Key benefits include:
Reduced confined space entry requirements
Improved cleaning effectiveness
Lower project duration
Enhanced safety performance
Reduced waste generation
Improved operational efficiency
Our high-capacity Jet Vac fleet delivers effective drain cleaning services for industrial sites, terminals, processing facilities and utility infrastructure.
Combined with our advanced CCTV survey technology, we can identify blockages, assess pipe condition and provide detailed reporting to support proactive maintenance programmes.
Services include:
Drain cleaning
Sewer jetting
CCTV drainage surveys
Pipework inspections
Blockage removal
Preventative maintenance programmes
