SOIL WATERPROOFING

Leading Provider of Environmental

Solutions

EarthSealNanotechnology solution to help retain the strength of road bases by adding significant water resistance to treated soils.

Works on silanol, the functional group of silicon, present on the surfaces of all silicate soils.

Reactive soil modifier that creates alkyl siloxane bonds to greatly reduce the opportunity for water penetration into the soil.

Almost 99% of soils contain silicate– Clays and Silts are over 80% silicate– Sand is over 95% silicate

– THEREFORE EARTHSEAL IS EFFECTIVE ON ALL SOIL TYPES!

The Problem

Wet Cycle : Expansion - Water absorption & adsorption during rain increases the diameter of hydrated soil causing expansion.

Dry Cycle : Contraction- Evaporation of water from the wet soil causes contraction.

Expansion & Contraction The combination of these two processes causes cracking of the soil base, increasing its vulnerability to further water ingress and further loss of strength / increased deformation due to water.

The Solution

EarthSeal converts soils from waterloving (hydrophilic polar) to waterhating (hydrophobic non polar).

Therefore EarthSeal provides significant water resistance to treated soils and eliminates the Expansion and Contraction problem.

EarthSeal Application- Applied topically to the

soil- Standard Equipment –

water truck / spray boom

- Can be applied as a mix in for roads with poor drainage or built in low lying areas

EarthSeal Applicability- Widens that envelope of

applicable soils- Used to augment high silt,

high liquid limit road conditions that react poorly in wet weather due to silts poor cohesive properties

- Applied after EarthZyme slurry coat
