Grouting

Ground Improvement methods such as 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. It can be used for soil stabilisation, waterproofing and soil mixing to increase the strength of soil and many other applications.

Compaction grouting is a ground improvement method which is used to increase the density of the soil. This method of grouting is usually used to rehabilitate settlement of sensitive structures.

The works are carried out from the surface, with the grout bulbs created from the bottom-up in successive stages of 1m. The degree of densification depends on the type of soil treated and the grid pattern selected for the injection points, with injection rates generally varying from 4 to 6m3 per hour, with that reducing to 2m3 per hour in particularly sensitive conditions. Injection pressure is generally in the range of 1 to 4MPa.

Compaction grouting can also be carried out from an existing basement or locations with limited headroom, and it is possible to drill through hard material to reach the low strength strata beneath for treatment.
