Social housing subsidence

Effective solutions for social housing subsidence

Subsidence in social housing can be a significant concern, as it affects the safety and well-being of residents and can also lead to financial implications for the housing provider.

As experts in dealing with social housing subsidence, Mainmark offers solutions that get both houses and multi-occupancy social housing properties back to normal as quickly as possible.

Traditionally, resolving social housing subsidence would have required underpinning or piling, a complicated, time-consuming, and expensive process that would have required building occupants to vacate the property while work was carried out. But Mainmark’s modern methods simplify the process, treating soical housing subsidence with minimal disruption.

Our Teretek® resin injection and JOG computer-controlled grouting are alternatives to mechanical jacking, underpinning and piling. They deal with the root cause of the subsidence, providing:

  • Ground improvement – Increasing the ground’s load-bearing capacity and mitigating liquefaction under social housing.
  • Lifting and re-levelling – Bringing the property back to level.
  • Void filling – Injecting material into voids in the soil helps to stabilise the foundation.

Our technologies are effective and quick to implement, often taking only a day or two to complete, and occupants can often remain in their homes during the work.

Resolving social housing subsidence

Addressing social housing subsidence is not only a matter of property maintenance but also a social and economic issue for property owners and inhabitants.

Social housing subsidence can have many adverse effects, including:

  • Structural damage – Subsidence can lead to cracks in walls, ceilings and floors, misaligned doors and windows and uneven floors.
  • Damp and mould – The damage caused by subsidence can lead to problems such as damp and mould in the walls and draughts that can make it difficult to keep the property warm in the winter, putting vulnerable occupants at risk.
  • Safety hazards – The structural instability caused by social housing subsidence can pose safety risks to occupants.
  • Decreased property value: Subsidence can reduce the value of social housing properties and render them unsuitable as housing for the people who need them most.

If social housing subsidence is suspected, treating the problem as soon as possible is essential. This will help to avoid any additional issues developing, ensuring the safety and habitability of the housing and the long-term value of the housing stock.
