High-pressure water jetting and electromechanical machining is used to clean both internal and external drainage. This is to prevent pipework from blocking and maintaining flow, it could also help if you are experiencing bad smells.
Both methods are effective at clearing blocked drains and also removing silt, soft, deposits, scale, fat, grease, rag, cement, roots, removing objects and much more from drain runs and sewers.
High-pressure water jetting is carried out by sending water from a tank through a pump then into a hose. A water jetting attachment fit for the works is applied to the end of the hose which is sent down the drain or sewer with the pressurised jets of water cleaning the pipework. The pressures used are typically between 1,000 psi to 15,000 psi.
Electromechanical machining is a reeled cable being sent down the drain with cleaning attachments on the end of the cable. The cable is then spun at a high rpm causing the cleaning attachment to scrape the inner walls of the drain to clean the pipework. We can carry out these works on drainage up to 300mm in diameter. We can use this technique to remove scale, roots, cement and fat from drains
