Sewer Renovation, Rehabilitation and Relining
Damage to sewers can mean major risks and inconvenience to individuals and whole communities, not to mention headaches for the local authority or water and sewerage company (WaSC) responsible for maintaining the network.
With traffic in the UK reaching saturation point in many areas, minimising disruption to the road network is critical. Little wonder that the travelling public and local communities are keen to see repairs carried out efficiently and quickly, with the least impact on their daily lives.
The very real effects of damaged or collapsed sewers can include sewer flooding, pollution, foul odours and public health hazards. These are all situations which need to be rectified ASAP, but the sheer logistics of excavating and repairing large sections of sewer can make fixing it a real challenge.
There is good news though. At Lanes, cured-in-place piping (CIPP) sewer renovation is our default technique in the majority of sewer repairs. And using CIPP — also called no-dig or trenchless technology — we are able to rehabilitate sewers and drains, from 225mm to 2,500mm in diameter, without digging up roads or pavements.
We’ve been a leader in this practice for many years, and pride ourselves on our top-notch service and outstanding results. We really do minimise disruption, whether we’re carrying out an emergency repair job or routine maintenance work to head off future problems for years to come. What is more, our prices are always competitive.
What is trenchless sewer repair?
No-dig, trenchless or CIPP sewer relining involves inserting a liner impregnated with special resin into the sewer. As the liner is installed, it is turned inside out and forced through the pipe using either water or air pressure. The resin bonds to the inside of the pipe and then cures or hardens, creating a pipe within a pipe and restoring the integrity of the drain or sewer. For localised repairs to isolated defects or cracks, we may use short lengths of CIPP liner known as patches. Either approach is as effective as the other; we would always recommend the most cost-effective solution for each situation.
How much does this cost?
Our pricing is competitive across the board. Since each sewer renovation project is different, the course of action will be dictated by the condition and type of pipe in question, along with various other factors. At Lanes, we make sure the costs and proposed work match your needs and your budget.
How long do sewer renovations last?
We test lining materials for a minimum of 1,000 hours to ensure that they meet WRc criteria which specifies a 50-year design life. But we take that further still, building in a safety factor of 2 to offer an average life expectancy of around 100 years. Our installations may also be independently verified by Excova for further assurance that they conform to the highest industry standards.
Why choose Lanes?
Lanes has over 20 years of specialist experience in this field, renovating mainline sewer systems regionally, across entire counties, and nationally. Currently we hold the record for installing the longest single length of liner in a sewer.
As pioneers in lining technology, we are comfortable using any of the sewer renovation techniques, including the newest and most innovative, such as UV-light liners which cure at a super-fast one-metre-a-minute, for example. Managing large-scale projects on public infrastructures whilst maintaining services as far as possible for clients and the public is something we do on a daily basis.
