TerraSil and ZycoBond are easy to apply soil modifiers that reduces water permeability and improves maximum dry density (MDD) & flexibility of the soil bases.
TerraSil permanently modifies the soil surface, making it hydrophobic. It chemically converts the water absorbing hydroxyl groups to water resistant alkyl groups. ZycoBond is a nano-polymer that chemically binds soil particles together into a flexible cross-linked network, thereby improving the load bearing capacity and flexibility of the soil bases.
It also complements conventional soil additives like cement and lime by eliminating the degradation of the cementatious bonds thus increasing durability. This innovative solution improves the strength (CBR) and stability of the locally available soils, thus offering a cost effective method for road construction.
TerraSil and ZycoBond is mixed in situ with the soil as a part of the water of compaction (OMC Water). Due to their ability to be introduced through water, the solution mixes and distributes into the soil extremely efficiently. The application as water solution helps to avoid dusting issues. Furthermore, the low dosage rates of TerraSil and ZycoBond significantly reduces the transportation costs to site.

Water Resistant Soil Bases

Moisture damage is the leading cause of failure for soil sub layers and dirt/gravel roads. Infiltration of water can cause the soil to expand and loose cohesion, leading to ruts, corrugations, cracks and ravelling. TerraSil is an easy to apply soil modifier that permanently eliminates infiltration of water in to soils. Making soil bases/dirt roads impervious to water has a significant impact on overall life cycle costs

Bond coat additive for unbound layers (Prime Coats)

Cationic bitumen emulsion additive that enables a deeply penetrative prime coat that is track resistant and waterproof. TerraPrime forms a permanent chemical bond between the prime coat and soil base, thereby enabling high bond strengths, track resistance and lower residual bitumen contents.
