• Drain Repairs & Relining

    If you are suffering with damaged drainage, there are several options that Grey-Water Drainage can deploy to resolve the problem.

Why would you use a Drain Repair or ​Relining Service?

Drain Relining
Your commercial and residential drains will likely over time experience wear and tear, and this can cause cracks to appear, water infiltration and damage to the existing pipes. In the past, the solution to this problem was to dig up and replace the drainage system completely, or relocate it to an area where there was less risk of damage (such as root ingress or flooding). However, Grey-Water Drainage use the latest non-dig drain lining services, as well as the best drain relining equipment, meaning this is no longer the case.

No Dig Required

We can typically repair all types of drains without digging, keeping your costs to a minimum using our innovative solutions.

No Heavy Equipment

No industrial equipment on your premise, we only do what is necessary - and only do what you authorise, once we have consulted with you first.

What is drain lining and how does it work?

Structural lining of a damaged drain is a “non-dig” method of repair and sealing of damaged drain lines. Grey-Water use a resin-based fibre liner which is inserted into the damaged drain after being impregnated with the correct mixture of chemicals and then inflated by either air or water via an inner tube. Once the liner has hardened, the inner tube is removed and the liner is left in place as a permanent repair. 

One of the added benefits of a liner is that it creates a straight-through section of run without any joints where roots can penetrate and force the pipework to become displaced.

How to determine internal drain damage
Grey-Water Drainage use CCTV drain inspection surveying equipment to thoroughly check the internal damage and whether any drain repairs are required. Our CCTV surveys allow us to check the internal quality of your drains, noting any faults found within the system, so that we can advise you on the best course of action specific to your requirements. This allows us to assess the quality of your drains with as little disruption to your home or work as possible.
Common problems that require drain lining systems
If the Grey-Water team discover any of the following problems with your drains, drain lining solutions could be a viable solution and may be required:
  • Open joints
  • Root ingress
  • Water infiltration
  • Movement of the ground
  • Cracks
  • Hole in the pipe
If we discover your drains have been damaged by any of the above, we may recommend our non-dig drain lining technology. The structural lining of your drainage system is important to ensure durability, functionality and generally prevent further problems from occurring.
What are the benefits of structural lining
The main benefits, including the following:

  • Cost-effective repair with minimal disruption 
  • Resilient to ground movement
  • Forms a barrier to water ingress and root penetration
  • In the majority of cases a structural liner will outlast the original pipework
  • A structural liner will have no joins allowing for a continuously smooth surface for the waste to flow through
  • All liners come with a 5-year guarantee (not insurance backed)
  • Can save you thousands of pounds if drains are lined before they deteriorate.

Structural lining saves Grey-Water customers hundreds of pounds and can be installed simply – in a matter of hours – without the need for costly and disruptive excavation.

​Drain Excavation

Drain Excavation
A total collapse or severe deformation of a drain or sewer will require an exercise to excavate and repair the pipe. Reasons drains collapse or deform vary from ground movement and subsidence, tree root infestation, incorrect installation or excessive loading from changes to the environment above them. A drain excavation is, in most cases, the final resort of treatment for a damaged drainage system. It involves our team digging a hole or trench, providing direct access to the affected areas.

Excavating Experts

We know where the problem is and we know where to excavate. Minimizing disruption to you and your property.

Complete Guidance

We show you where the problem is and discuss how we are going to access and resolve it. We will give you all the options and let you make informed decisions about what is best for your property.

Construction Familiarity

We support construction projects, both domestic and commercial. Meaning you get the expertise at home and the skilled support you need on site, keeping to project deadlines.

Total Drainage Solutions

We carry out full drainage services which ensures that we are there to support you with every step or your project, or resolving your problem.

When is drain excavation necessary?
The Grey-Water Drainage consider a full excavation to be the final resort solution. Only once we have carried out investigation works and tried or ruled out any other solution we will discuss the idea of excavation work as and when needed.
Pre-excavation Survey
In the event of an excavation, the Grey-Water Team will carry out an extensive pre-excavation survey and diagnosis, ensuring we locate the exact digging location to ensure the most cost effective and timely repairs or installations possible.
How disruptive is drain excavating?
We often have to excavate within people’s property and know how highly disruptive this can be to customers. Customer’s expectations along with minimising any disruption in these situations are very important. 

The Grey-Water Team will produce a detailed plan encompassing site assessment, health and safety considerations, storage of the excavated material and site reinstatement. We are always careful to reinstate and restore the site to your satisfaction.

Frequently Asked Questions

When should I have my drains repaired?

If you are concerned that your drains might be damaged, you should take action as soon as possible. We are on-hand to help with any inquiries, utilizing state-of-the-art equipment to assess and repair any damage to your drains.

How long does it take to repair a drain?

The length of repair depends on the extent of the damage. It could be your drain just needs relining, or if there is found to be large structural damage, it may need replacing entirely. Generally we are able to sort out a problem on the same day, identifying the problem and using expert tools for drain patching and larger issues.

How much does drain repair cost?

Our repair fee comes down to how much of your drain needs attending to. Factors that affect the total sum range from what kind of damage has been done - a drain could have been taken over by root ingress, or it could have cracked due to temperature or storms - to how far along the drain damage has been sustained. Our rates generally start at £350.

How much does drain relining cost?

Typically a lining or relining depends on the length of the drain. Where we will have to remove damaged lining or damage to the drain itself, this will require time and precision. A relining will generally cost upwards of £400.

Do I have to pay in advance for drain repairs?

Due to previous experiences, we ask for payment in advance of drain repairs.

Do I need my drains repaired?

After a routine survey, we will have more information and can decide whether your drains need repairing. A survey will mean feeding a CCTV camera through your drain system to look for any damage or blocks. You may already recognize problems with your drains, however this doesn't always mean repair is needed; it could be a block that needs remedying.

Is there a local drain repair service near me?

If you live in the Kent or London area, we have local operatives in your area who are able to carry out drain excavation and repair. Give us a call and we will provide you with our next available visit date.

Can I repair a drain myself?

Due to the specialist training and equipment needed in order to repair drains effectively, only experts are qualified to perform this service. With the complexity of some drain systems, someone without proper training will not be able to navigate to the source of the problem and take measures to repair it. Talk to us today and find out how we can save you stress and money with our experienced staff.

Do you repair sewers?

We do undertake sewer excavation and repair, as well as sewer relining to improve the integrity and prevent any collapses. Speak to us today to find out how we protect and secure sewers.

How do you unblock an external drain?

Depending on the type of blockage, we might use specialised pressure washers or pumps to unblock an external drain. Once a thorough survey has been undertaken to ascertain the cause of the blockage, we can better understand what is required to deal with it.
