Terrasil and Zycobond solution when sprayed, makes the soil layer waterproof. The permeability is reduced to 10-7  – 10-8 cms/sec., which stops the capillary rise / makes the base impermeable to water from the top.

  • 100% organosilane, water-soluble, reactive soil modifier
  • Reduces water permeability of soil bases, whilst maintaining 100% vapour permeability
  • Forms a breathable waterproofed stone base layer
  • Maintains frictional values between silt, sand, clay particles leading to retention of strength and resistance to deformation
  • Maintains dry CBR in wet season
