dead weight solid rock adjoining
straight to pour a keyway
in plan a cavity shear
slightly a fault adjacent
to be curved a grout curtain metal water stops
to resemble heel of a dam a joint
a triangle to drill inspection galleries
pressure a block to permit
to exert dimension access
solid to alter maintenance
hollow alternately a gate
a cofferdam to sprinkle a valve
to proceed lateral surfaces intercepting drains
to complete asphaltic emulsion to seep
outlets adherence to shrink
overflow dams low-heat cement to liberate
non-overflow dams a crack to paint
