Project summary<\/span><\/strong><\/h3>\nDuring a Horizontal Directional Drilling (HDD) project, the generated slurry needed to be dried prior to disposal due to environmental risks associated with water leaching onto public roads and the surrounding environment. The previously adopted approach involved adding 100\u2013200% dry soil to the material, followed by a waiting period of up to one week for complete drying. This method made the process slow, operationally inefficient, and costly.<\/p>\n

Implemented Solution<\/span><\/strong><\/h3>\nThe Environmental Department responsible for the project selected MF003, MetaFLO\u2019s solidification reagent. The dosage was adjusted according to the slurry\u2019s moisture content, varying with material conditions and reaching up to 0.75% for a volume of 6.5 m\u00b3 per day. Using the excavator already available on site, the product was incorporated into the slurry and, within up to 30 minutes, absorbed the free moisture, eliminating leaching and enabling safe, efficient, and environmentally compliant handling and disposal of the solidified material.<\/p>\n
Technical Details<\/h4>\n\n- Applied product:<\/strong> MF003 \u2013 MetaFLO solidification reagent<\/li>\n
- Application method:<\/strong> Incorporation of the reagent into the slurry using the excavator available on site<\/li>\n
- Treated material characteristics:<\/strong> Slurry with variable moisture content between 40% and 70%, composed of different soil and rock types<\/li>\n
- Technical performance:<\/strong> Retention of free moisture and solidification of the material, enabling safe handling and disposal of the waste<\/li>\n
