As experienced drainage engineers we feel it should not take longer than one hour to clear a general domestic blockage. If we are unable to clear the blockage within the hour the cause will be reassessed and we shall advise from site. If necessary, more extensive works will be recommended and undertaken at the clients discretion.
It is recommended that all drains are cleaned regularly to prevent the build up of waste which, if left, can cause blockages. This is especially relevant in the food industry due to the high usage of fat.
DESCALING & ROOT CUTTING
This involves the removal of root intrusion, scale build-up and concrete ingress with the use of high pressure water jetting and / or mechanical cutting.
We provide a DVD and full written report, including a site drawing, with recommendations for remedial work if required.
HOUSE PURCHASE SURVEYS
For house purchase surveys we can record straight to DVD on site and this can be provided to you immediately minimizing any purchasing delays.
REPAIR BY EXCAVATION
Excavations to damaged drains carried out where relining is not possible or pipe work is too defected. This can be carried out through all types of ground surfaces to a depth of 5 metres.
We are Streetworks qualified and therefore certified to carry out highway excavations.
REPAIR & NEW INSTALLATION
We carry out repairs and new installations on the following:
- All pipework / gullies / manholes
- Manhole rehabilitation
- Septic Tanks
- Treatment Plants
- Land Drainage
CIPP (Cured in Place Pipe) Lining
INTRODUCTION TO PIPE LINING
One of the most common methods for re-lining drain runs is to install a cured in place pipe liner. This involves the sealing of defects consisting of circumferential cracks, longitudinal cracks, off-set and open joints, redundant runs, root intrusion and water infiltration (depending on the type of resin).
We use various installation methods and resins as required for the specific job, re-lining drain runs saves costly excavation works, with minimum disruptions as this is a non-dig method of repairing drain runs / cable ducts.
Listed below are the different methods of lining which can be used depending on the client's requirements.
DRAG-IN LINING (75mm-300mm)
To re-line defective drain runs / cable ducting, which prevents costly excavation works. This method is generally used on drain runs without bends.
INVERSION LINING (75mm-300mm)
To re-line defective drain runs / cable ducting, which prevents costly excavation works. Inverted liners are used to negotiate multiple bends, including 90 degree (rest bends) and diameter changes in pipework.
LOCALISED PATCH REPAIR (75mm-300mm)
To carry out pin-point repairs within a drain run which prevents the need for full re-lining. As with inversion lining localized patch repairs can negotiate diameter changes. Due to the type of resin used with patch repairs this will also seal off water infiltration.
LATERAL CUTTING (100mm-150mm)
This involves the cutting of intruding connections / junctions. This is also used for the re-opening of connections / junctions after re-lining or patch repair.
