Understanding The Science Behind Chemical Grouting

Chemical grouting is quite a bit different from the usual grouting processes. Grouting typically fills in spaces between tiles or blocks and cements the tiles or blocks to each other and to the surface on which these tiles or blocks are placed. However, chemical grouting works very differently and is used for other purposes. Here is more on what chemical grouting does and understanding the science behind it.

Chemical Grouting

Chemical grouting uses a non-particulate, low-viscosity grout. This is injected into specific spaces to immobilize objects. Because it fills in thousands of microscopic holes and spaces of the surrounding soil (yes, injected into the soil), nothing can shake or move the objects that are buried below the top layer of the soil when the project is complete.

The Science Behind It

This particular kind of grout bonds on a molecular level with the surrounding soil. The soil becomes much harder, almost like cement. It also becomes very dense. To remove any object that is stuck in the soil and the chemical grout, you would have to excavate the soil from around the object and the grout and from underneath the object itself. Then you would have to use a crane to lift the compacted soil and chemical grout up to get the object out.

Why Chemical Grout Is Chosen

Chemical grout is chosen when the surrounding soil is extremely soft and will not support the weight of the construction on top of it. Chemical grout is also ideal for any type of soil that readily bonds to the grout and makes a very solid anchor for walls, poles, posts, etc. Contractors from companies like A-PAC Pressure Grouting Inc. may choose to use chemical grout to secure the foundation of large buildings in areas where the soft soil and earthquakes may shake the building and cause it damage. Because chemical grout requires very little water to mix, it is a preferable material in places where it is difficult to get water or too expensive to transport water to the construction site.

Working With Your Contractor

If your contractor suggests that you use chemical grout to anchor your building or project, be sure to ask why. If he/she shares any of the valid reasons for use (as listed above), then you know that your contractor knows what he/she is doing. You also know that your project will be very secure when the construction contractor has completed your building or project.
