New Scientific Proof - Injected in Soil, AV-100 Chemical Grout Will Not Shrink
Injection Grouting has evolved responsibly over the years, yet some beliefs are slow to change. For those who believe that grout expands and contracts with wet/dry climate cycles, Avanti commissioned an independent lab to perform field testing and analysis that proves otherwise. In a White Paper published in September 2018, Doug Cobos, Ph.D., validated that relative humidity (RH) is a constant 100% for depths consistent with underground sewer systems. In the lab analysis, AV-100 validated zero desiccation over time - meaning its properties (ability to seal and eliminate infiltration) are permanent.
