So, when looking at possible drain repairs, the first step to any potential work is a camera drain survey, to determine the work that will be required to complete any repairs, and the best method to complete the required work.
Pipe Material and Condition
A drain repair survey first identifies the type of material used for your pipes (clay, PVC, etc.) and the extent of deterioration of the material. This often includes older pitch fibre pipes that have delaminated (where the layers have come apart) and often collapsed inward. As houses of this nature were typically built from the 1950s onwards, there is a good chance that the use of pitch fibre has been made in the design of your home.
Joint Displacement and Misalignment
A joint is where older style drains fail most, typically due to pipe joints moving out of alignment.

Tree Root Intrusion
Roots enter the drains through cracks in joints in the drains. A CCTV Drain Survey Northampton contractors can complete will show exactly how far a contractor would need to clear a set of roots and also show the density of the roots in the pipes. From this information a contractor can determine whether a simple cut-and-clear would be a cost effective option or if relining would be a better option.
Blockage Location and Composition
Grease, silt, and compacted debris are found in most blockages and can respond differently to jetting. The blockage can be located and described to give the most appropriate method of cleaning.
Whether Relining Is an Option
A major part of any drain survey is to see if your pipes can be relined. This means that instead of having to dig up your garden to repair damaged pipes, they can be repaired from the inside. For -based drain surveys, Wilkinson Environmental assess whether your pipes can be relined as part of their Drain Survey.
Having a before survey gives you full knowledge of what you have before you start any repair conversations.
