Mainmark technicians repairing rail subsidence inside a tunnel using resin injection

Mainmark has successfully re-levelled and re-supported everything from concrete slabs and pavements all the way through to improving the ground foundations of major roads, bridges, runways, ports and seawalls, railways and utility plants. In fact our technology is so versatile we can help improve the soil strata in almost every environmental condition.

Our non-invasive, cost and time efficient technologies are a suitable alternative solution to underpinning for many businesses whether they operate in the commercial, industrial or heritage, infrastructure or mining sectors.

Our eco-neutral products and solutions quickly fill voids and weak spaces under the ground, improving the ground-level and strength and offering a safe and long-lasting solution to subsidence. Projects can often be turned around within days, with minimal detrimental effects on the environment, pollution and noise-levels.

For all projects, no matter the scale, we offer a free-in persons site survey and quotation.

Mainmark technicians repairing rail subsidence inside a rail tunnel

If you’re a property owner you can benefit from a completely free in-person or telephone inspection survey and full quotation with Mainmark.

During the survey, the site inspector will:

  • Visually inspect your home, looking for signs of subsidence, such as cracks, sticking windows and doors and uneven floors.

  • Take measurements to determine if there has been any settlement or movement of the ground.

  • Review historic data and records to understand your home’s history and any previous subsidence issues.

The subsidence inspection will ensure a comprehensive analysis of the issue affecting your home, considering the size and the layout of the property, as well as the extent of the subsidence.
