ENTACT has been designing effective solidification/stabilization programs for onsite waste treatment remedies for over 19 years, treating millions of tons of impacted materials with our own recommended reagent blends and specialty equipment, as well as implementing conventional solidification/stabilization with more commonly known additives. ENTACT holds several mixing equipment and reagent patents for the treatment of various wastes. We have utilized both our proprietary technologies as well as other common applications (e.g. Portland cement, bentonite, etc.) to treat contaminated soils, sludges, and sediments in an effort to control valence states, buffer pH’s, increase bearing capacities, reduce leachability, reduce permeability, prevent durability impacts, and remove the ability to produce a visible sheen on a multitude of contaminated soils. ENTACT’s in-situ solidification/stabilization solutions are supported by our bench scale treatability lab in our Houston office. This resource enables ENTACT to obtain first hand visual knowledge of the waste’s treatment characteristics while closely matching the equipment selection to that envisioned for the full scale operations. These critical variables provide real world solutions that are reproducible on a much larger scale. Specific services include:
Geotechnical (in-house)
- Moisture Content
- Gradation
- Wet and Dry Unit Weight
- Standard Proctors
- Atterberg Limits
- Hydraulic Conductivity
- pH
Chemical
ENTACT performs the initial raw waste evaluations, homogenizes the samples, mixes the candidate reagents, cures the samples in our facility, and then submits them to outside laboratories for off-site analyses, including:
- Total VOCs, SVOCs, Pesticides, Metals, and PCBs
- SPLP or TCLP
