Soilworks products are the industry’s top standard due to our insistence on creating high performance soil stabilization and dust control products that stand up to rigorous testing – both in the lab and in the field. Our commitment to quality and performance has led to our involvement and testing in hundreds of real-world situations. The following library of reports, presentations, specifications, approvals and other similar documents provide you, our customer, the transparency and dependable assurance that is expected from Soilworks.
The EPA has applied Soiltac across Lāhainā wildfire burn zones to stabilize toxic ash and debris, preventing airborne contamination and hazardous runoff into coastal waters and surrounding properties. This EPA-reviewed, non-toxic soil stabilizer forms a thin, clear protective crust, helping to contain hazardous materials such as asbestos, lead, and arsenic while allowing safe re-entry and cleanup efforts. Soiltac remains effective for 4 to 6 months unless disturbed and will be fully removed during Phase 2 debris cleanup by the U.S. Army Corps of Engineers.
Key Benefits:
Minimizes airborne ash exposure, reducing respiratory and environmental risks.
Prevents contaminants from entering fragile marine ecosystems.
Transparent coating allows safe sifting through materials.
Application is mandatory for public health and environmental protection.
Additional Information:
Cultural sites, artifacts, and historic structures are not sprayed.
Reapplication may occur if significant disturbances impact coverage.
Residents can remove Soiltac from objects using hot water or steam.
For disaster recovery, hazardous dust control, and erosion mitigation, Soiltac provides a trusted, government-approved solution. Contact Soilworks for consultation on environmental protection strategies in emergency response efforts.

Maui gives so much to the world. As guests, we are honored to give our support back.
Ash and debris on properties affected by wildfires on Maui may impact wildlife, marine life, and people’s health as they can contain harmful contaminants like asbestos, lead, and arsenic. Ash and debris can spread by wind, rain, re-entry, Phase 2 debris removal, or events where ash is disturbed.
Maui County—with the Hawaiʻi Department of Health (DOH), Federal Emergency Management Agency (FEMA), United States Army Corps of Engineers (USACE), and EPA—requested using soil stabilizer to control ash and dust in the areas impacted by the wildfires.
EPA successfully applied soil stabilizer in Kula on September 25, 2023, and after the Mayor approved applying Soiltac® in Lāhainā in mid-October, EPA began applying it thereafter.
Ash and debris can contain harmful contaminants like asbestos, lead, arsenic, and other hazardous substances.
impact breathing and cause infections.

residents and workers are protected.
Before application, EPA teams and cultural monitors will closely study the building footprint and surrounding area to ensure wildlife, animal feeders, personal items, or other unintended items are not impacted by application.
Soil stabilizer will not be applied to historic or cultural areas or items previously known or flagged by cultural monitors.
We anticipate there will be a need for reapplication based on significant disturbances (after it has been applied), weather events, and/or solar degredation. But our first objective is to apply the soil stablizer to all ash footprints. For more information, please contact our hotline at: (808)-539-0555.
The soil stabilizer is effective for four to six months if it is not disturbed.
Soil stabilizer is not intended to permanently control ash. After residents visit their properties, the U.S. Army Corps of Engineers will remove ash, debris, and the soil stabilizer during Phase 2.
Residents cannot opt out of soil stabilizer application. Soil stabilizer will be applied to all properties in Lāhainā to protect residents’ health and fragile coastal and marine ecosystems.
Yes. Run it under hot water or steam it, then wipe the surface with a soft cloth. The Soiltac® will remain non- toxic, even during removal.
