Drain Lining and Patch Repair Terms and Conditions


These terms and conditions and to be read in conjunction with the company general terms and conditions provided.

  1. Prior to any lining works, a CCTV survey and report must be carried out to assess the drain and its suitability to be lined.

  2. There are many factors that can alter the integrity of a drain liner, it is vital that we are provided with details of any substance that is running through the drainage system prior to any lining works are carried out. Our resin selection is based on this information - no responsibility will be taken for information not supplied to us should this have a detrimental effect on the liner once installed.

  3. Heat running through a drainage system can also have a detrimental effect to certain types of liners, if there is the possibly of heat from any source running through the system, it is the customers responsibility to inform us prior - no responsibility will be taken for information not supplied to us should this have a detrimental effect on the liner once installed.

  4. During lining works it may be necessary to seal off any connecting drainage while the works are on-going. Over pumping and/or tanker removal can be provided (if site conditions allow), if required this will be charged in addition to the lining costs.

  5. Any active connections will be re-established by ourselves once the lining works are completed for any active lines.

  6. The assumption is made that the condition of the drain is the same as when the original CCTV survey was carried out. Given the unpredictability of defects on drainage systems, if there are any changes and the lining works cannot be completed as planned, the materials and labour cost would be chargeable as the materials must be prepared prior. This would be supported by CCTV evidence.

  7. The assumption is made that all access conditions of the site are the same as when the original CCTV survey was carried out. If there are any changes and the lining works cannot be completed as planned, the materials and labour cost would be chargeable as the materials must be prepared prior. This would be supported by CCTV evidence.

  8. If the liner were to fail in situ to reasons beyond our control (e.g. weather conditions, heat unintentionally added to the system, equipment breakdown, etc.) every effort would be made to remove the liner and reinstate the drain. If this is not possible, re-routing or another option may be required, additional charges would be incurred. Any costs incurred to keep the site operational whilst the alternative option is carried out would also be chargeable.

  9. If damage or loss is sustained to the companies equipment due to reasons beyond their control or due to defective pipe work or some other unknown risk, the company reserves the right to charge for the costs of retrieving the equipment, including the instruction of another contractor and/or costs to replace the equipment and all associated equipment. The company also reserves the right to charge for loss of profits at the rate of £250 (Excl VAT) per day due to downtime of the equipment up to a maximum of 7 days. If after this time the equipment has not been retrieved, the Employer is fully responsibility for full replacement of the equipment and all associated equipment costs.

  10. If access is required is required onto private land it is the customers responsibility to ensure all relevant permissions are obtained prior to our attendance.

  11. Access is required on site to site any tools and associated equipment while the lining works take place. It is the customers responsibility to ensure this access is available.

  12. If we are required to work within a confined space as defined by the Health and Safety At Work Act, we reserve the right to charge for any additional safety equipment.

  13. If the planned dates for works cannot be carried out due to reasons beyond our control (e.g. weather conditions) the works will be rearranged at the earliest opportunity.
