Especially in Silty and Clayey soil


Injection Grid Patterns Matter…

Injection Grid Showing Uniform

Spacing between rows and points are uniform throughout grid, but vary depending on the soil type and depth of the injection intervals. Shallow injection intervals and clayey/silty soil type require tighter injection patterns, especially with injectables such as Trap & Treat® as they are suspended solid slurries where water is being used as the carrier/delivery fluid.  Spacing between points and rows for the injection patterns may vary from 5’ to 10’ centers.
