While a considerable data base has been gathered over the last two decades or so with regard to the performance of seals, most of the information is presented in research reports and widely scattered papers in journals and proceedings of conferen978-94-010-7173-4978-94-009-1505-3

Strength Parameters of Cement Borehole Seals in Rock,vel nuclear waste repository need to be sealed reliably to retard any radionuclide migration to the accessible environment (US Nuclear Regulatory Commission, 1983, 1985). Design of seals may also be required in (1) water dams, barriers, water wells, mine drifts or shafts, to prevent flooding of unde

Performance of Bentonite and Bentonite/Crushed Rock Borehole Seals,d longevity in nature (e.g. Meyer and Howard, 1983; Pusch, 1983). Bentonite is used extensively for sealing boreholes. Under certain circumstances advantages can be gained by sanding bentonite or by mixing bentonite with crushed rock.

Performance of a Clay-Based Barrier,n a variety of waste containment facilities. When compacted and applied in an earthen waste containment barrier the surface-active clay mineral montmorillonite can impart the desirable properties of low hydraulic conductivity, low contaminant diffusivity and chemical retardation. Moreover, depending
