Sealing of boreholes and underground excavations has not received
much engineering attention until fairly recently. The growing
awareness of and sensitivity to environmental concerns of the
technical community as well as of the public at large has resulted
in an increasing recognition of the fact that these geological
penetrations may have an environmental impact. The issue of
possible contamination resulting from migration along boreholes,
adits, shafts or tunnels unquestionably has been raised most
forcefully with in the context of nuclear waste disposal. Several
nuclear waste disposal programs, notably the Civilian and the
Defence programs of the US De partment of Energy, the US Nuclear
Regulatory Commission and the Canadian and Swedish radioactive
waste disposal programs have conducted major research efforts aimed
at developing adequate seal designs for penet rations in host rock
formations for high-level nuclear waste repositories. 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 conferences. Hence, the
materials are not readily accessible to potential users such as
designers, contractors or regulators who are not familiar with
nuclear waste disposal programs."
