Terrasil

Technical Data Sheet

Definition

TERRASIL is a fifth generation organosilane, reactive at room temperature, soluble in water and bitumen, and hydrolytically stable. It provides a permanent waterproofing to the aggregates, while improving the compaction even with less moisture of compaction.

Action mode

Terrasil’s molecules are diluted in water at room temperature. When the water enters Terrasil in contact with the soil, the Terrasil molecules are attracted by the polar groups (Silanol Group) of the soil and remain attached until the water evaporates, at which time they form a chemical covalent bond by condensation. This bond (Siloxane) is extremely strong and is not reversed in conditions of humidity, ultraviolet radiation or temperature. Once the aggregate is covered by hundreds of millions of hydrophobic molecules, the soil will be water-repellent, which has a very important effect on the characteristics of the soil.

Benefits

  1. The treated soil achieves permanently hydrophobic characteristics.
  2. The soil maintains transpiration (it expels water in the form of vapour).
  3. It reduces the plasticity index of the soil.
  4. CBR values are increased.
  5. Swelling is reduced.
  6. The Resilience Module is improved.
  7. Density and compaction data on site are improved.
  8. It is possible to reduce the water consumption necessary for the compaction of the material.
