What Is The Difference Between Permeation Grouting And Controlled Hydrofracture Grouting?

If you have issues with soil stabilization on your property, it can lead to all kinds of problems and even put any structure on your property at risk. Thankfully, soil stabilization has been made easier due to the development of a rectifying process known as soil grouting. Soil grouting involves injecting concrete-like material into the soil to stabilize those areas where the soil is too fluid or flexible. There are two primary forms of soil grouting: permeation grouting and controlled hydrofracture grouting. Before hiring soil grouting professionals like those at T. Luckey Sons, Inc., you'll want to know what the differences are between the two methods. Here are a few facts about both permeation grouting and controlled hydrofracture grouting to help you understand.

Permeation grouting and controlled hydrofracture grouting involve different processes.

With permeation grouting, the goal is to make the soil a more solid mass. On the other hand, hydrofracture grouting involves actually causing deliberate disruption to the existing solid masses in the ground for the purpose of making them more stable. The end goal, of course, is to make the ground more stable. However, the two different soil grouting techniques involve highly different processes, different equipment, and a different end result on certain levels. 

Permeation grouting is more widely used in small settings.

Permeation grouting is something that is going to be more widely used in smaller scale settings. For example, if a homeowner owns a house that is situated on top of soil that is constantly shifting and changing, permeation grouting works out well. Alternatively, hydrofracture grouting is probably going to be used in larger settings most frequently. Just because the ground has a lot of rock does not always mean stability, especially in large areas where larger structures are planned to be built. Therefore, breaking down some of the rock that is present and creating a more continuously stable ground is necessary. 

Permeation grouting does not build volume but hydrofracture grouting does. 

Permeation grouting mainly involves injecting a chemical-laced material into the ground that will harden as it cures. This does not change the shape of the ground or the volume of the ground. So permeation grounding can be accomplished without there being a visible difference from above ground. With hydrofracture grouting, a more fluid material is pushed into the ground with tremendous amounts of pressure to break solid masses apart. When this occurs, there can be natural changes in the volume of the ground. Permeation is more like filling a void whereas hydrofracturing is more like building upon what is already there.
