Stabilizing soil helps protect your property and landscaping, but it's not a quick deal. Companies that work with soil grouting and other stabilization techniques need to thoroughly investigate all of the issues affecting the soil to ensure that the stabilization procedures will work. It sounds odd at first because grouting is often used to mitigate these problems and increase stability. But if the soil faces certain conditions, the grouting may not work as well. For best results when having soil grouting done, the company needs to ensure the following won't interfere.
For the most part, soil grouting can work on a variety of soil types. However, it tends to work better in soil that's mildly to moderately basic, meaning the pH value is above 7 (which is the neutral point on the pH scale; below 7, the numbers represent acidity). If you have time, you may be able to amend the soil with the addition of lime or another base. However, if you don't have time, or if the area being stabilized is too large to amend effectively, the soil grouting usually can still proceed, but the company has to be careful to use a grouting material that works well with more acidic soils.
Soil grouting is a very good tactic to use to combat soils that are unstable in seismic zones, such as fill that could liquefy in strong shaking. However, if the area is currently dealing with a quake swarm, for example, grouting may have to wait. Very small quakes (e.g., a swarm of quakes around 1 or 2 in magnitude) may not really have an effect. But swarms like those that hit Reno in 2008, in which most of the quakes were over 2 (and a number were over 4 in magnitude) generally make construction and preparing for construction more difficult.
The same goes for stabilization that needs to be done in times of heavy rain to prevent erosion. Grouting may have to wait because continual rain makes it harder for the grout to work. There are other stabilization techniques that companies can use to stop erosion, at least temporarily, while waiting for the rains to let up.
Soil grouting works very well when given the chance, so companies are careful to evaluate all the factors that could affect the soil during the proposed work period. Once a company determines that the soil is able to handle grouting, work can begin. Contact a service, like T. Luckey Sons, Inc., to get started.
