The stability of dams in the form of fractured rock, gravel, sand or soil embankments is impaired by external impacts, mainly hydrological loads, but also by root penetration or pest infestation.
This frequently requires reconstruction measures, e.g. the restoration of the external, internal or core sealing which help to prevent water ingress or other damage. Supportive curtain injections, especially in the base area, the stabilization of the supporting shell, measures against hydraulic fracturing in the soil or the post-construction restoration of the sealing apron, for example, serve this purpose.
Product requirements: good penetration; good adhesion properties; low cost; compatible with existing construction materials.
