On pre-construction projects, in most cases mixing the chemical into the soils through a process of excavation, mixing & replacing of the soils is recommended.

If you are interested in detailed specifications about how this process or the others are carried out, simply fill in our request for information form to the right and we will be happy to email them to you.
Here’s a great case study of this type of project: Pre-Construction Mixing Example
