<p>In a method of splicing strips (10, 11) of thermoplastic material to form waterstop joints, the strips (10, 11) are first clamped in longitudinal alignment with their adjacent ends spaced apart. While the strips (10, 11) are so clamped, a routing tool (25) is used to cut complementary rebates at these adjacent ends, after which the strips are moved into end abutting relationship while the longitudinal alignment of the strips is maintained, the rebated ends being brought into a half-lap configuration. The cooperating ends are then welded together by means of an electric heating element which was inserted between the ends prior to their being clamped together.</p> |
