CCTV Inspection
Whether you are looking into a specific problem, or needing a full site survey, we have the equipment and experience to fulfil your requirements.
Our survey capabilities include pipework from 100mm by push rod camera, up to 1500mm by “crawler” camera, and sizes above this by actual man entry.
Surveys are recorded on to videotape, or DVD, and the report can be typed or on CD. Still photographs can also be made to accompany the video.
The survey notes are presented in an easy to read format, and are coded up to Local Authority Adoption Standards.
Cure Lining
Once a problem has been identified, rectification will usually involve excavation and replacement of the pipework, or the installation of a cured in place liner. Without getting into job specifics, we have installed liners into literally thousands of miles of pipes over the years, and this includes all sizes, shapes and lengths of drains. Whether you need a patch liner to cover a small defect, or a 100 metre liner in a 1500mm fast flowing trunk sewer, we have been there before, and we know what we are doing!
We also have the capabilities to remotely remove intruding connections, and open lateral connections from blind junctions. Even single access lining can be carried out in certain situations.
The resins and materials we use have been tested and approved for use in all normal drainage pipework, and specialist materials can be utilised for quite a number of industrial process operations.
Prior to the installation of any liner, the pipes would be cleaned and inspected by CCTV. Any root growth, or other feature which would deform the liner is removed, and only then is the liner fitted.
Hot or cold cure lining is a Water Authority approved method of sewer rehabilitation, and all our linings carry a 10-year guarantee.
Specialist Grouting
Often when a site is being redeveloped, the existing drains and sewers will have to be diverted or abandoned completely.
This redundant pipework is sometimes simply dug up and removed, and the trench backfilled.
However, it may be more cost effective to leave the pipes in place, and fill them with grout, which will set solid. This is usually the case with larger pipes that are either too deep to realistically dig up, or where other services criss cross the site, and cannot be disturbed.
Insitu’s specialist grouting teams have all the knowledge and experience to be able to carry out this type of operation to Water Authority standards, and do it safely.

Transport and Waster Disposal
In an ideal world, the drains should contain just water and sewage, and never need cleaning. HA! This is the real world, and all sorts of things and stuff get into the sewers. Things like, oil, petrol, paint, chemicals, decomposing food, and all manner of nasty stuff! Once it’s out of your pipes, and into the back of our tanker, we have to get rid of it somewhere, and somewhere legally!
All the waste disposal sites we tip at are licensed to handle various types of hazardous waste, and every load discharged is subject to the issuing of a waste transfer document. This document shows where and when we tipped your waste, and what tonnage the tanker was carrying. A copy of this transfer note forms the basis of what you get charged for the waste disposal element of the work we have done for you.
