Grouting

Aarsleff has the specialist plant and labour to carry out all types of drilling and grouting works from the filling of redundant coal mines to chemical injection using tube a manchette. Drilling and grouting can be used for soil stabilisation, waterproofing, soil mixing to increase the strength of soil and many other applications.

Ground Improvement methods such as Deep Compaction and Grouting are used to improve the existing soil formation by changing the soil properties. They can increase the bearing capacity or provide settlement control for new construction, or to remedy an existing issue. Ground Improvement does not create structural elements to ‘bridge’ unsuitable soil layers but rather improves the ground itself to allow for shallow foundations. Grouting can be used for soil stabilisation, waterproofing and soil mixing to increase the strength of soil and many other applications.

Aarsleff understands that every site presents its own unique challenges, so you need a bespoke approach to find the best solution. We don’t just deliver: we work with you from the outset, designing schemes that meet all regulatory requirements providing you with a value engineered solution.
