Pavements waterproofs

Technical Data


This pavement maintenance technique allows us to preserve the pavement against the ageing of the bitumen layer and volume fluctuations in the base.

Waterproofs cracks, potholes and surfaces. Maintenance irrigation is recommended depending on traffic and environmental conditions.

Mode of Action

Terrasil is a soil modifying additive composed of 100% organosilanes, soluble in water, stable to heat and ultraviolet radiation. Its main action, therefore, consists in the waterproofing of soils and subsoils.

It has silanol groups, which react with the silicates present in the soil, transforming its surface and giving them permanent hydrophobic properties. In this way, the soil will repel the water molecules, waterproofing it and avoiding the problems derived from its presence.
