Infrastructure such as railways, roads, bridges and airport runways can often suffer from ground subsidence, deteriorating infrastructure and broken pipelines that can cause serious issues to public safety and expensive damage in need of urgent repair.

Mainmark can provide vital ground engineering and preservation solutions designed to raise, re-level and re-support ageing infrastructure in order to enhance its safety and stability.

Our cost-effective solutions have been expertly developed to resolve infrastructure issues quickly with minimal disruption and operations can continue during the remediation work.

What is subsidence and the causes?

Subsidence is the downward movement of the foundations of a building or structure due to changes in the soil conditions. If foundations have been built on sloping ground, overtime the structure will slide, damaging the groundworks. Some of the most common causes of subsidence to infrastructure include:

Ground vibrations from passing traffic or nearby excavations

Incomplete, poorly executed or ageing foundation works

The structure has been built on compressible clay soil that can either shrink or swell depending on the amount of moisture

Extreme weather conditions can affect soil conditions ā€“ excess water damage can weaken the soil and its foundations or droughts can result in plant roots further draining and therefore shrinking the soil

Soil underneath the structure has not been correctly compacted

Signs of subsidence

One of the major signs of subsidence occurring to infrastructure is the base or structure becoming uneven or tilted. This can apply to roads, railways, bridges and airport runways as well as many of types of infrastructure.

The first steps to resolving ground subsidence is to identify its presence. You can do this by looking out for:

  • Unexpected movement or damage to the structure
  • Unstable road slabs or rails
  • The structure appearing to lean slightly in one direction
  • Water damage and saturation of the base or ground beneath a structure, particularly affecting railway lines

The sooner subsidence can be identified, the quicker remediation can begin. Many elements of infrastructure can have their life extended by careful re-levelling or improvement of the stability of the ground beneath or around them.

Mainmark can provide comprehensive ground stabilisation and re-levelling solutions that are environmentally inert and designed for fast, easy application. To contact our experienced team, click here.
