Improving the soil for new construction was the next development of Compaction Grouting. The compaction grouting process starts with drilling that points that are established around the perimeter of the home or structure. Once the drilling is finished, the grouting can begin. A specific mixture of grout is pumped under high pressure into each drill point. The treatment involves the injection of a mortar, generally with high viscosity, under pressure and at a controlled flow rate, which displaces the soil around the drilling tool and subsequently compacts it. Pipe sections are removed as the grout is pumped under the surface. Specialized grout mixture’s ability to force its way under high pressure into loose, sandy soils and effectively fills voids and caps the limestone layer under the structure.
This method is useful in Sinkholes. Sinkholes can continue growing for a surprisingly long time, it could be years or even decades. It all depends on how long the roof of the hole can support the weight of the solids above. If the cover over the sinkhole is solid and supportive then sinkholes could grow to cover wide areas.
Below is the common Compaction Method:
Chemical Grouting: This is a void filling method in which polyurethane foam is injected to fill the void and support the foundation above. This method is often used in shallow soils and to fill voids that have opened up beneath slab foundations. To fill the void completely, binding the soil together to provide extra support for the foundation on top. The foam lifts the slab to its original position, fixing issues that were caused by a settling or uneven part, and fills the sinkhole or void at the same time.
Cement Grouting: This method referred to as compaction grouting or low-mobility grouting. In cement grouting, a cement-based grout is pumped into the ground through steel casings. The strength of the cement allows this method to be used for deep void filling at a high pressure, although it can also be used in lightweight soils at a lower pressure and with an open cement mixture. Cement grouting is commonly used to fill large voids, as it makes the soil thicker and seals the limestone surfaces, providing great support for the building above.
There are several different types of chemical grouting that use different products of pressure and have differing levels of foam expansion.
