Residential House Subsidence

Are you worried about extension subsidence in your home?

Extension subsidence is an issue that requires immediate attention. If you suspect your home may be experiencing this problem, it’s crucial to seek professional advice promptly to prevent further damage.

Extension subsidence often arises from issues with the soil beneath your home’s foundations. Mainmark specialises in addressing subsidence in residential properties and offers solutions that target the underlying causes, helping to restore your home’s foundation.

Common causes of extension subsidence include:

Inadequate foundation: When an extension’s foundation is poorly designed or constructed.
Soil shrinkage or erosion: Typically due to flooding or extended dry periods, leading to moisture loss in the soil.
Historical land use: Activities like mining can impact ground stability.

Mainmark provides non-invasive and cost effective solutions for extension subsidence utilising it’s Teretek® technology.

Extension Subsidence Issues

If left unaddressed, extension subsidence issues can worsen, leading to increased damage that may require demolishing or rebuilding the extension. Recognising the early signs of extension subsidence is crucial for timely intervention and avoiding further complications.

One common indicator of extension subsidence is the visible gap between the extension and the main house. This separation often manifests as cracks in the internal or external walls where the extension connects to the home. Not only does this separation signal potential subsidence, but it can also pose safety risks; it may create drafts and allow rainwater or moisture to infiltrate your walls.

Cracks in Walls or Ceilings

Jammed Doors & Sticking Windows

Jammed doors and sticking windows are often the first indication of damaged foundations due to movement of foundation ground and soils under a home.

Sinking or Uneven Floors

Sinking concrete floors or slabs are an indication of building subsidence.

Leaning of the Extension

Once a building starts leaning and becomes unlevel, fixing it immediately is crucial, or risk further damage and potential hazards. This requires foundation repair, footing repairs, and house re-levelling.
