Read moreEvery property owner knows the stress of dealing with leaking or damaged drains. When a drain fails, it can cause unpleasant odors, damp patches, slow drainage, and even structural damage to your home or business premises. Fortunately, modern technology provides a lasting and cost-effective solution for drain lining.
At Coastal Drains, we’ve helped thousands of homeowners and businesses repair and protect their drainage systems using advanced drain pipe lining techniques. In this comprehensive guide, we’ll explain how lining a drain not only repairs existing problems but also prevents leaks, root intrusion, and costly damage in the future.
What Is Drain Lining?
Drain lining, also known as cured-in-place pipe lining (CIPP), is a trenchless drain repair method that restores the inside of damaged pipes without excavation. Instead of digging up and replacing your existing pipes, a flexible liner soaked in resin is inserted into the drain line and cured to form a hard, seamless “pipe within a pipe.”
This modern approach offers a durable, efficient, and environmentally friendly alternative to traditional drain replacement. Whether you’re dealing with cracked pipes, leaks, or corrosion, drain lining companies like Coastal Drains can repair the issue quickly and with minimal disruption.
Why Drains Leak or Fail
Before we explore how drain lining prevents leaks and structural damage, it’s important to understand why drains fail in the first place.
1. Cracks and Fractures
Over time, underground pipes may crack due to soil movement, pressure, or natural wear. These cracks allow water to escape and weaken the surrounding ground.
2. Root Intrusion
Tree roots are a leading cause of sewer pipe lining damage. They seek out moisture and can infiltrate small openings, eventually blocking or breaking the pipe.
3. Corrosion and Age
Older clay or metal pipes deteriorate over time, losing their structural integrity and leading to leaks.
4. Ground Movement
Shifting soil, traffic loads, and freeze-thaw cycles can displace pipes, creating misalignments or collapses.
5. Poor Installation or Materials
Low-quality materials or poorly fitted joints can cause premature failure, resulting in recurring leaks and drain blockages.
If you suspect your drains are leaking or damaged, it’s important to book a professional drain inspection as soon as possible to prevent worsening structural problems.
How Drain Lining Works
Lining a drain is a precise process that involves several key steps. At Coastal Drains, our experts use advanced equipment and techniques to ensure a seamless, long-lasting result.
Step 1: CCTV Drain Survey
Before any work begins, a CCTV drain inspection identifies the exact location and cause of damage. This step ensures that the drain lining is suitable for your situation.
Step 2: Drain Line Cleaning Service
The pipe must be thoroughly cleaned before the liner is inserted. Using high-pressure water jetting, debris, roots, and scale are cleared away to create a smooth surface.

Step 3: Inserting the Liner
A flexible liner coated with special resin is inserted into the pipe and positioned precisely over the damaged section. The liner is then inflated so it adheres to the inner walls of the pipe.
Step 4: Curing the Resin
Using hot water, steam, or ultraviolet light, the resin cures and hardens to form a durable, watertight seal, essentially creating a new pipe inside the old one.
Step 5: Final Inspection
Once cured, the liner is inspected again using CCTV cameras to ensure the pipe is structurally sound, leak-free, and fully functional.
The Benefits of Drain Lining
Drain lining offers a wide range of benefits that go far beyond simple repairs. Here’s how this method helps prevent future leaks and structural damage:
1. Seamless and Leak-Proof Protection
The resin lining creates a jointless, watertight barrier, eliminating the weak points where leaks usually start, such as joints and cracks. This prevents water from escaping and damaging the surrounding soil or foundation.
2. Prevents Root Intrusion
Roots can’t penetrate a seamless liner, meaning sewer pipe lining provides long-term protection against tree root damage, one of the most common causes of drain blockages and leaks.
3. Reinforces Structural Integrity
Once cured, the lining adds strength to the existing drain, improving its load-bearing capacity and extending its life expectancy by up to 50 years.
4. Minimizes Disruption and Cost
Unlike traditional excavation methods, drain lining near me services can usually be completed within a day, without digging or property damage. It’s faster, cleaner, and often half the cost of replacement.
5. Environmentally Friendly Solution
Because it preserves the existing pipe, drain lining reduces waste and environmental impact, making it the greener choice for modern plumbing repairs.
How Drain Lining Prevents Structural Damage
Leaking drains can cause more than just plumbing issues; they can threaten the structural stability of your property. Here’s how drain pipe lining helps prevent long-term damage.
Prevents Ground Erosion
When water seeps into the soil, it washes away fine particles and creates voids beneath foundations and pavements. Over time, this can lead to subsidence. By sealing the pipe completely, drain lining prevents water leakage and protects your property’s stability.
Protects Against Damp and Mould
Leaky underground drains can cause damp patches in floors and walls. A fully lined pipe ensures no moisture escapes, reducing the risk of rising damp and mould.
Strengthens Old or Fragile Pipes
If your property has older clay or pitch fiber pipes, lining a drain reinforces the structure, reducing the chance of collapse under pressure.
Long-Term Reliability
Once lined, your drain is resistant to cracks, corrosion, and future infiltration, providing decades of protection without repeated repairs.
When Should You Consider Drain Lining?
Drain lining isn’t just for emergencies. It’s an excellent preventative measure that can stop minor issues from becoming major repairs.
You should consider drain lining if you experience:
- Frequent drain blockages or slow drainage
- Gurgling sounds or bad odors from drains
- Damp spots or sinkholes near the property
- Tree roots growing close to underground pipes
- Recurring leaks after previous repairs
If you’re unsure, our drain repairs team can carry out a CCTV survey to determine whether pipe lining is the best solution for your system.
Drain Lining vs. Traditional Drain Replacement
| Feature | Drain Lining | Traditional Excavation |
