Cement injections for stabilising foundations

When is soil cementation performed?

Cement grout injection is suitable for stabilizing the soil under the foundation of a building. The purpose of introducing cement slurry into the pores of the soil is to fill them and "stick them together". The end result is a significantly stronger ground base, not susceptible or slightly susceptible to subsequent re-compaction.

Портативното инжектиране може да се изпълнява в тесни пространства като сутерени (мазета), коридори, в тесни пространства – между къщата и ограда, коридори и други. Циментацията на почвата може да се прилага и във вътрешни зони на сградата.

When is cement injection in foundations applicable?

Cement injections are suitable for most soils in Bulgaria. A certain porosity of the soil is required, as well as the ability to drive the lancet tips to the desired injection depth. In different cases, complete cementation of the area under the foundations or the formation of strongly strengthened zones under and around them is sought.

Are there additional factors limiting cementation?

In order to apply this method, it is highly desirable to first carry out a geological survey of the terrain. The results of this survey will clearly show the applicability of the method, the estimated quantities of cement, the density of the injection points and the depth of injection. The geological survey also provides clarity about the probable percentage of certainty of soil stabilization.
