How deep does RRP penetrate into the soil?
There is no way of stopping it from penetrating further; it can continue to go deeper and deeper. EXAMPLE: RRP penetrates to a depth of 2 m into the ground and there encounters 100% dry soil. At that moment the RRP reaction comes to an end. However, if subsequently, as a result of a rise in the ground-water level or capillarity, slight traces of moisture penetrate from below into this RRP-processed soil, the RRP reaction will instantly extend further downward. Therefore: RRP always acts where it comes into contact with water. Because of this great penetration depth a road base processed with RRP is significantly better and qualitatively superior to conventionally constructed road or road base.
