Brunnen-Dämmer® Type 1
Brunnen-Dämmer®Type 1 is a hydraulically setting dry mortar specially designed for damming annular spaces during well construction (DVGW - ‘German Association for Gas and Water’ leaflet 121). The free-flowing suspension is applied with a subsequent hardening process to provide a permanent seal for water horizons. The use of a natural lime marl with an enriched clay component and highly active swellable bentonites has a very positive effect on impermeability and elasticity (modulus of elasticity).
- Brunnen‐Dämmer Type 1 is suitable for use in water protec on zones I and II
- For well and borehole ﬁlling and annular space sealing, the hydraulically hardening building material produces ﬁrst‐class results
- Special binding agents ensure stability against sulphate‐containing water
