The most experienced specialists in providing Subsidence rectification

A house is a precious possession both from a financial and emotional perspective. But as years pass by, issues such as wall cracks may develop. While minor issues can be easily sorted, house subsidence can be a severe issue that should be addressed immediately.

What is subsidence?

Subsidence is the sudden or gradual sinking of the ground beneath the foundation of your house. Some causes are man-made, whilst natural factors also cause or contribute to subsidence.

Tree Roots Causes House Subsidence

Are you living in a house with subsidence? Causes of house subsidence

Natural Causes:


  • Quality of ground (soil)

The natural properties of soils is a significant cause of subsidence. Wet or dry clays & silts tend to swell & shrink, thus making the structure above it vulnerable to movement. Gravel and sand-based soils are more likely to subside due to getting washed away owing to their non-cohesiveness. Either of these can damage the foundation of your house.


  • Tree Roots

We all appreciate the benefits of the lush greenery beside our home, but it can make the structure more susceptible to subsidence. Tree roots are likely to cause subsidence as these roots absorb moisture from the soil beneath the foundation, causing shrinkage. Tree roots can also cause uplift as they grow larger under a structure.


Man-Made Causes:


  • Leaking drains

Water from the leaking downpipe or drain seeps into the soil under the foundation, causing the ground to soften, which can cause subsidence.


  • Poor Foundations

There is a higher likelihood of subsidence if the building foundation is of poor design or quality of construction. Foundations with inadequate capacity to support the structure can cause or contribute to subsidence.c

Mines or underground structures (tunnels)

Structures built upon previously mined land are also susceptible to subsidence. Tunnelling projects beneath properties can also contribute to or cause subsidence. 


  • Nearby Construction work

Excavations can cause harmful vibration levels and changes in the water content of the ground that can damage nearby structures and cause subsidence.
