What Is Drain Relining & Do You Need It?

Drain relining is a method used to repair damaged or deteriorating drainage pipes without the need for extensive excavation. It involves inserting a liner or resin-coated flexible tube into the existing pipe and inflating it to conform to the shape of the pipe. Once in place, the liner hardens, creating a new, durable inner lining within the old pipe. This process effectively seals cracks, leaks, and other defects, restoring the structural integrity and functionality of the drainage system. This process can be highly effective in fixing issues such as cracks, fractures, and root intrusion, with minimal disruption compared to traditional drain repair methods.

Here are some key points that will answer the questions “What is drain relining?” and “Does my home need drain relining?”…

Drain Relining Repairs Damaged Pipes

Drain relining is typically used to repair damaged or deteriorating pipes that have cracks, fractures, or leaks. These issues can result from various factors, including age, corrosion, tree root intrusion, ground movement, or poor installation. Drain relining also prevents joint displacement. In traditional drain systems with separate pipe sections joined by connectors or joints, movement and shifting of the soil can cause these joints to become displaced or misaligned over time. Drain relining creates a continuous, seamless pipe without joints, reducing the risk of joint displacement and associated damage.

Drain Relining Stops A Crack Becoming a Fracture

One of the primary purposes of drain relining is to seal any cracks, fractures, or leaks in the existing pipe. By applying a resin-coated liner inside the damaged drain, the relining process effectively creates a new, seamless pipe within the old one. This prevents water from escaping through cracks and leaks, reducing the risk of further damage to the surrounding soil and structures. Carrying out drain relining at the earliest possible sign of cracking is a good preventative measure, as a small crack, when undetected can very quickly become a broken drain pipe, bringing with it extensive damage or it may even produce a slow and continuous leak, that over time leaches into the surrounding ground damaging landscaping, foundations and more.

Drain Relining Is often Required Because of Root Intrusion

Tree roots seeking moisture and nutrients are a common cause of drain damage. When drains develop cracks or joints, roots can penetrate them and grow inside the pipe, causing blockages and further damage. Drain relining creates a smooth, seamless surface inside the pipe, eliminating the entry points for roots and preventing future root intrusion.

Drain Relining Prevents Further Damage

Left untreated, damaged drainage pipes can lead to more significant problems, such as blockages, flooding, and sewage backups. Drain relining provides a proactive solution to address issues early and prevent further damage to the plumbing system by strengthening the pipe.The resin-coated liner used in drain relining forms a strong, durable layer inside the existing pipe. This not only seals cracks and leaks but also reinforces the structural integrity of the drain. The new liner can withstand external pressure and environmental factors better than the original pipe material, reducing the likelihood of future damage such as collapse or deformation.

Some drain relining materials are also resistant to corrosion, which is a common issue in older drain systems, especially those made of metal. By installing a corrosion-resistant liner, drain relining helps protect the pipe from chemical damage caused by acidic or alkaline substances in wastewater, extending its lifespan and preventing further deterioration.

Drain Relining Is Less Disruptive Than Traditional Pipe Repairs

One of the main advantages of drain relining is that it minimises disruption to the surrounding area. Unlike traditional pipe replacement methods that require excavation and disruption to landscaping, driveways, or structures, drain relining can often be completed with minimal digging or disturbance. Unlike traditional drain repair methods that involve digging up the entire length of the damaged pipe, drain relining typically requires only small access points at either end of the section to be repaired. This means minimal disruption to landscaping, driveways, or structures above the drain.

Drain relining can often be completed in a fraction of the time it takes to excavate and replace a drain pipe. Depending on the extent of the damage and the size of the pipe, relining can sometimes be done in just a few hours, reducing the time your property is affected. Because there’s no need for extensive excavation, there’s also less mess associated with drain relining.

Drain Relining is Cost-Effective

Drain relining is generally more cost-effective than traditional pipe replacement methods, as it requires less labour, time, and materials. Additionally, it eliminates the need for costly excavation and restoration work, making it a more economical option for repairing damaged drainage pipes.

While drain relining may initially seem more expensive than traditional repair methods, the overall cost can be lower when you factor in the reduced labour, equipment, and restoration costs associated with excavation. Additionally, the quicker completion time can save you money on labour and inconvenience.

Drain Relining is a Long-Term Solution

Drain relining provides a long-term solution for repairing damaged pipes, with the new lining expected to last for many years. The durable, seamless lining creates a smooth interior surface that helps prevent future clogs, blockages, and corrosion, extending the lifespan of the drainage system. Drain relining creates a durable, seamless pipe within the existing drain, often with a lifespan of 50 years or more. This means you won’t have to worry about future issues with the repaired section of the drain, reducing the likelihood of future disruptions.

Drain ReliningShould Be Carried Out By Professionals

If you’re experiencing issues with your drainage system, such as recurring blockages, slow draining, or sewage odours, it’s essential to have a professional plumber assess the problem. They can determine the extent of the damage and recommend the most suitable repair method, which may include drain relining if the pipes are repairable.

In summary, drain relining is a cost-effective, minimally invasive method for repairing damaged drainage pipes and restoring the functionality of the plumbing system. If you’re experiencing issues with your drainage system, consulting with a professional can help determine whether drain relining is the right solution for your needs.
