Drain Relining Services in Auckland

What is Drain Relining?

In this method, the cracked drain pipes are fixed using a new pipe called the “lining.” These lining pipes are gradually inserted into the damaged pipe without excavating the whole site. Drain lining falls under the No-Dig Repair Technology approach which utilizes an arrangement of aligning drain sleeves equivalent to glass-reinforced plastic.

Drain relining is very effective to mend broken or leaking joints and cracks along the circumference of the pipe caused due to blockages. It can also successfully fix the damages caused due to tree root invasion in the drain lines.

Our expert drainage technicians can help fix even the most damaged pipes with drain lining and transform them into smooth-flowing pipes. It takes a certain level of experience, which we have in abundance, to detect the notoriously tricky defect locations. We use the most modern technology and equipment to rectify these damages, protect the environment from wastewater leaching into the soil and ensure better longevity for your drain network.

How is drain relining done?

1. Drain Inspection

The first step of the drain lining process is to perform an exhaustive evaluation of the current state of the pipes, the extent and the severity of the damage. CCTV cameras are used to survey the insides of the pipes to make informed decisions on how to fix the defects.

2. Clearing Of Debris

The next step is to clear out any obstructions in the pipes. These may include tree roots, piled-up debris or any other waste matter clinging to the insides of the pipelines. Usually, hydro jetting or robotic machines with cutters are used to remove these obstructions, which is followed by a thorough cleaning session. This step is important and non-negotiable because a clean surface ensures a stronger bonding of the relining material to the pipes.

3. Preparing the lining

Different types of drain damages require different types of pipe lining. The third step is to prepare and finalize the type and dimensions of the required pipe lining based on the requirement.

4. Installation

There are two ways you can install pipe lining in the drains. The first method is called inversion, where a resin mixture is poured into the drain liner and rolled repeatedly. The mixture needs to be distributed consistently to get the desired thickness. The final structure is inserted into the damaged pipe with the help of inflated airbags and fitted to the shape of the pipe walls using water pressure. The second method is called GFRP UV pipe lining. In this method, the lining is inserted into the defective pipe using standard cables and tools.

Both methods are equally effective. However, you should ensure that the installation is done only by trained technicians. Accurate fitting is crucial for efficient drainage and durability.

5. Treatment

Once the installation is done, the lining is allowed to harden and bond with the insides of the pipes. If you follow the inversion method of lining, it will harden by itself. If necessary, hot water can be used to accelerate the hardening process. If it is the GFRP UV process, the pipe lines need UV lighting exposure to achieve the desired hardness.

6. Follow-up Inspection

The technicians will conduct one final round of evaluation and inspection on the effectiveness of the curing process and that the pipeline is now ready and good to go. This inspection is also done using CCTV cameras.

Non Destructive

When you choose pipe relining instead of replacing the damaged and cracked drain pipes, you also ensure non-destruction of your yard and infrastructure. It is, by far, the least messy process of drain repair

High-Quality & Long-Lasting:

Drain lining using no-digging technology is undoubtedly more convenient, budget-friendly than conventional drain repair process. Not only that, the process does not compromise on durability, resilience and strength that a critical operation like drain layout needs for a property. Drain lining is a reliable and quality repair approach that will last for a really long time.

Fast and efficient

You would be amazed at the amount of time and labour drain lining saves for the property owners as well as the technicians during the installation process. It can be completed in less than half the time taken by conventional drain repairing processes.

Environment Friendly

It saves the property and surroundings from ecological damage that results from excavation.

Cost-Effective

Drain lines achieve the same efficiency that a replacement of pipe will bring to your drains. This way you save a huge amount of money in terms of excavation, new pipes, installation charges and more.
