Conclusions 1. For design of the antifiltration components in the karstic rock, the entire potentially karstic mass was usually closed off with curtains. 2. The constructed complex of antifiltration components, consisting of a grout curtain, concrete-filled karst hollows, and local concrete crosscut walls corresponds to the difficult geologic conditions of the Chain-N'yan massif. 3. The adopted work organization, with construction of tunnels cutting across the entire karst mass, simultaneous rock grouting, and more precise determination of the geomorphology made it possible to considerably reduce the proposed volumes and costs of the antifiltration components of the Hoabinh hydraulic development. 4. The adopted scheme for providing a working face for the antifiltration measures at El. 133 m was the optimal. It opportunely permitted ensuring readiness of the high-head front for filling the reservoir to El. 112 m in November 1990, and to the NPL at El. 125 m in September 1991.
