    Drain Lining & Localised Structure Repair

    At KD Drainage we understand that as a housing association or letting agency, the last thing you want is the disturbance of ground excavation or having to spend a substantial amount of money on new pipework- with drain relining and LSR, this is unnecessary.

    Drain Relining

    Drain relining and localised repair structure (LSR) are cheaper alternatives to traditional drain excavation methods. If your pipework is damaged, relining and LSR essentially gives you a new set of pipes without having to buy a brand-new set. Furthermore, typical ground excavation is not required, due to the trenchless method used by KD Drainage, presenting you with a mess-free alternative to traditional methods.

    Drain relining attaches a protective layer to the inside on an existing pipe, creating a shield against damage such as cracks for up to 50 years. Drain relining is typically used for diameter ranges of 100mm to 1200mm.

    Localised Structure Repair

    Localised structure repair, also known as drain patching, is similar to drain relining and has the same benefits, however, only a small portion of the pipework undergoes corrective work. At KD Drainage, we tend to work with pipework with a diameter of 100mm to 450mm and a length of 1 metre.

    You can read more about drain relining and LSR in our blog posts.

    It is essential to have one of our specialist engineers assess the damage of your pipe to ascertain whether drain relining or LSR is possible or whether the pipework needs to be replaced.

    If you are unsure whether you require drain patching or drain relining please call us on 01622 919012 or email info@kddaa.co.uk to receive direct advice from our specialist engineers. We offer drain relining and LSR throughout London and Kent to both domestic and commercial clients.

    Sewer Connections

    If you own a private drainage system, it must be connected to the main sewer or directly to a treatment plant.

    The main sewer connection is a connection from your property to the key pipeline in a sewer system. This sewage is typically transported to a sewage treatment plant. A sewer connection ensures all sewage and waste is guided away from your property in a safe and reliable way. In the instance that you do not have an on-site builder to install a private drain, particularly for domestic housing, KD Drainage are also able to provide this service.

    We offer sewer connections to housing associations and letting agencies throughout London and Kent. Our drainage experts are highly experienced in the installation of main sewer connections, so you can rest assured you will receive the best service. If you would like to talk about your options in more detail, waste no time in contacting KD Drainage today.

    How do KD Drainage install sewer connections?

    1. Our engineers will visit your site/property, free of charge, to establish any site requirements and location of your drains.
    2. We would then have to request a drainage plan from the local water authorities. During this stage, a CCTV survey of your drainage system may be necessary.
    3. Once a plan has been established, we can then apply for the sewer connection to be made.
    4. Upon acceptance, KD Drainage will organise the job from start to finish, this is inclusive of all required road and footpath closures, diversion routes and all road applications to the local authorities.

    At KD Drainage, our engineers hold the requires NRSWA certification, allowing us to fully deliver these projects.

    What are the benefits of a sewer connection?

    Compared to your private drainage system being connected directly to a main treatment plant, a sewer connection is much more economical in the long-term. It is recommended that a treatment plant should be cleaned and maintained at yearly intervals. With a main sewer connection, there is no need for this.

    As a housing association or letting agency with multiple tenants, this could be more cost-effective in the long run.
