Home Buying Is Easier When You Know Your Remodeling Options

While I am not a professional contractor, I have a good friend who is. He often calls and tells me about his days and I have learned a lot about home renovations and remodeling options just listening to his stories. Knowing my home remodeling options greatly aided the shopping experience when I was ready to purchase my first home. I wanted to live in a location close to my family, and there were limited homes on the market in the area. However, due to knowing what changes could be made to an existing home, I was able to find a good house that I knew I could make great with just a few changes after I bought it. I was recently inspired to create a blog to share what I have learned about home renovations with anyone who would like to read it!

The Science Behind Chemical Grouting And Why It Works

Science has a way of creating dozens of new processes in many different fields. Take construction for example. In construction, you can use a process known as chemical grouting. Grout is injected into the ground to help stabilize a foundation. This may seem strange until you understand the science behind it and why it works.

Bonding with the Soil

When a low-viscosity (i.e., more liquid, fine particle) grout is injected into the ground, it bonds with the soil and fills the spaces in between the particles. The soil itself has to be rather fine, as it makes up the lack of particles in the grout. When it bonds with the soil, the grout mixture becomes complete and begins to harden.


Displacement is a scientific word that describes what happens when a liquid, solid, or gas is injected into another material and subsequently pushes (or displaces!) the original material from its position. With chemical grouting, that is exactly what happens when the soil and grout bond. They begin to push/displace the surrounding soil upward and outward into the only directions the soil can go once the grout displaces it.

Chemical Changes

Here is where the chemical part of chemical grouting comes into play. The bonded grout and soil turn into a massive sandstone. The grout has utterly transformed the soil in such a way that the soil cannot collapse or sink. The soil inside this sandstone mass is just a remnant of its former self. A chemical reaction has occurred, and nothing can change it back again, except maybe erosion.

Why Chemical Grouting Works 

Are you ready for this? Chemical grouting works because of the number of changes happening underground.

  • First, you have the looser soil bonding with the loose grout to create a fuller, stronger grout.
  • Then you have the entire lump creating displacement, which pushes upward against the foundation of the structure sitting above it. When that happens, the foundation can no longer sink, and the building becomes level again.
  • Finally, the hardened mass of grout and soil transforms into sandstone, a very hard substance that cannot be removed or displaced itself without putting more grout in the ground underneath the mass that was created. If you were to dig down around the sandstone mass, you could not break through it, and only time, wind, and rain could remove it.

If you think that this process could rescue your building from sinking, call a contractor in your area like A-PAC Pressure Grouting Inc.
