Usually, we find that customers are regularly told that a leaking drain requires a full excavation and renewal to repair either a whole drainage run or a localised area. Drainage is often affected by tree roots and their growth coming into contact with pipework. This can cause intermittent blockages that are usually expensive to clear, can cause a lot of inconvenience and also are hazardous to health.

Unfortunately, the cost of any excavation and drainage repair can be expensive and these processes aren’t usually covered by buildings insurance. This is the reason behind the development of insitu repair (repair without the need for excavation) There are many customers who require drain repairs in Crystal palace, and they can benefit from drain lining as it’s cost effective, efficient and a permanent method of repair.


There is other processes that don’t require a full excavation, such as structural soft felt lining. This method the installation of a new sleeve which fits inside the original damaged drain. The original pipe then becomes a host pipe to the liner. Before the liner is introduced into the drain, it is permeated with a resin. The resin is mixed together with a catalyst and an accelerator, which causes the liner to harden. Finally, a compressed air machine inflates the liner. This makes the liner expand to the shape of the host pipe, sealing it to a watertight condition.

When the liner has cured, it’s left in immediate working order. Long lengths can be completed in a single installation, and we have event installed liners of 100m+. These have been fitted on numerous occasions, and each one was completed within a day. When this method is compared against the traditional method of excavation, it’s clear to see the massive savings are made. These savings aren’t only in terms of cost, but disruption and inconvenience are kept to a minimum.

The benefits of structural soft felt lining don’t end with costs and time saving. It also provides many other features which include: improved flow and a section that doesn’t incorporate joints. This means the pipe has no weak spots, and therefore gives a long lasting solution. A typical liner is 3mm thick, so the cross section of the drain is minimal. This is much less than a joint which is slightly misaligned, which are common in the earthenware pipework.

All drain problems can develop and their condition can deteriorate, which is why we advise to call an experienced drain engineer at the point of you discovering a drainage issue. Some drain problems eventually get to the point that water loss can wash away the bedding material that is located below the foundations, and this creates voids. This will eventually lead to movement of the building, which will cause cracking of the walls and many further problems. The costs to cover these further problems would be extremely expensive and underpinning will be required. Even if the building’s insurance covers the cost of the underpinning, a record of the occurrence is kept and re-insuring can be both difficult and expensive.

Once the structural soft felt lining is installed, it’s covered against faulty workmanship and materials by our 15 year guarantee. Manufacturers however, say that the life expectancy is at least 50 years.

Have you recently thought about the condition of your sewers and/or drains? No?. Fear not, this isn’t uncommon. Many of our customers call us because they suspect something is wrong with their drains. This is usually because of a problem with an odour appearing from their drains. The main issue is that a drain blockage is usually an inconvenience. A blockage can be messy, smelly and sometimes even an emergency issue. Once dealt with properly, is the end of the story.


Here at Drainsmart we understand that being told your property has a damaged and leaking drain is only half the problem. Without CCTV drain survey, we are unable to reach into some depths in the drain and some problems can go undiscovered. Any drain problem can result in something far more serious if left untreated, as it can lead to subsidence and even movement of a building.

No-one knows what’s better for your home then you building’s insurer, and according to a leading specialist buildings insurer: “Approximately 25% of subsidence claims are directly related to defective drainage which has eroded the soil below the foundations causing the building to drop.”

With the use of CCTV drain survey technology, Drainsmart are now able to carry out blockage investigations in even the smallest of piping & drainage. With the footage and data that the camera captures, we’re able to accurately calculate the cost and time it will take us to rectify the problem.


The video footage that is captured during one of our CCTV camera inspections is recorded on to a DVD or hard drive where we analyse the imagery for closer inspection. A report will then be assembled and includes a computerised drawing showing the drainage layout of your building. A written report will describe a schedule of works if any defects are discovered in your drainage.


If you are in the process of purchasing a new home, you should always consider a home buyers drain survey. These surveys inspect the drainage systems and make sure there are no current or potential issues with them. If you disregard a home buyers survey and there is pre-existing drainage issues, you will probably find it hard to negotiate pricing with an insurer or the previous home owner. This means you may be liable for the damages to your property.

A home buyers drain survey can locate and identify any drainage issues. These range from small blockages to extensive problems, and everything in-between. This process is carried out by inserting a small camera to record the activity in the drainage systems. The recordings will then be stored and analysed by our professionals. Once the results have been collated and organised, our team will provide you with an extensive report.
