Drains services

MJ Abbott are "The Fifth Emergency Service" when it comes to urgent drainage problems. We are your first call for all things drainage, from blocked drains to routine maintenance, drain repairs and new installations. We are experts in CCTV drain surveys and No-dig technology.

High pressure water jetting

MJ Abbott's experienced and skilled drainage engineers use highly advanced and reliable jetting equipment for unblocking and cleaning drains up to 600mm (24 inch) diameter. Our Rioned high pressure jetter generates a maximum pressure of 200 bar at a flow rate of up to 60 litres a minute and has a remote control system, giving our engineers the ability to safely work away from the unit. The jetter carries 100m of high pressure hose and a full range of specialist cleaning, jetting and cutting nozzles of get through the most stubborn blockages.

The jetter can be used for the unblocking and cleaning of sewers, drains, pipes, interceptor tanks and grease traps. With a specialist "Warthog" rotary nozzle, it can also be used for root cutting and removal. This attachment is also very successful at removing scale and fat deposits. Following a blockage removal using the jetter, it is common to use our CCTV camera for an inspection, to ascertain the cause of the blockage and to advise of any remedial work which might be necessary.

If you have an urgent drainage problem, call our emergency line on 01722 717707.

CCTV drain surveys

MJ Abbott offer CCTV drain surveys using the latest Mini-Cam camera systems. These utilise either “push” cameras for up to 200mm (8 inch) diameter drains or "crawler" cameras for larger drains. These cameras allow close inspection of the inside of the drains and manholes to ascertain their condition, with the ability to record either video or still images direct to an integral hard drive for transfer to DVD or memory stick for the customer to view. Our camera systems are equipped with WinCan V8 pipe inspection software allowing our inspection reports to be presented in a clear and concise format.

CCTV drain surveys can be undertaken for home buyers' reports or pre-purchase surveys to give the potential purchaser and the mortgage lender peace of mind that the property's drains are in good condition, to view the drains following a blockage removal, or simply as part of an ongoing maintenance programme.

Drain repairs using No-dig technology

MJ Abbott are experts in No-dig drain repairs. This technology allows a drain to be repaired by installing a lining inside the existing drain which bonds to the inside of the pipe, thereby creating a "pipe within a pipe". This system offers a cost-effective alternative to carrying out excavations to enable a conventional repair, particularly when excavations would disturb an expensive paved surface or structure that is directly above the defective drain.

Resin liners are generally installed in a continuous length between two existing manholes, but they can also be used for small patch repairs to single joints, displaced joints and fractures, or simply to re-line existing drains to give excellent resistance to root ingress, improved flow characteristics and years of future integrity. Different types of liner are available for use with straight or curved pipes. The liner is impregnated with resin and then inserted into the defective or damaged drain from ground level. A secondary inflation tube is installed to inflate the liner to the outer diameter of the pipe. Once the resin has cured, using ambient temperature or hot water, the inflation tube is removed to leave a smooth “ready for use” liner.

Drain patch repair

Often it will not be necessary to fully re-line a defective drain. Localised repair or patching is an effective method for carrying out “on the spot” repairs. The process is similar to that of re-lining, but instead utilises a short liner within a specific area of the drain to repair cracks or a displaced joint. Patching can be installed at any location within an existing drain without the cost of a full re-line.

A resin is used to impregnate a fibreglass mat, which is then pre-wrapped around an inflation device (known as a packer). The packer is pushed or pulled to the defective area and inflated. The packer presses the patch against the wall of the pipe which is then left to cure, typically for 90-120 minutes depending on the ambient temperature. After curing, the packer is deflated and removed and the patch is inspected using CCTV before the repaired pipe is recommissioned.

Patching has a number of advantages over intrusive repairs via excavations: multiple patches can be installed in a similar time to a single excavation; there is no mess or need for expensive reinstatement; the patch seals against root ingress; and patches can be installed in radius sections and bends.

Drain replacement

When a drain has suffered a complete collapse, repair using no-dig methods is impossible. Our civils teams can excavate, replace any defective pipework and inspection chambers, and reinstate the work area to as near the pre-work condition as possible with very little disruption. Our operatives are qualified to NRSWA (New Roads and Street Works Act) standards, so work can be carried out in or near the public highway if required.
