POLYURETHANE RESIN SEALING FOR THE SHAFT LINING OF MOTORWAY A86

ETANCHEITE EN RESINE POLYURETHANE D'UN CUVELAGE DE L'AUTOROUTE A 86

The A86 motorway passes under national road 309 and under a railway track and, therefore, needs an absolutely reliable shaft lining sealing since the pavement of the motorway lies approximately 1 meter below the water-table fed by the seine. Among the various solutions considered (total waterproofing, internal or external sealing), internal sealing by means of a thin polyurethane resin film was selected. Laboratory tests (adhesion to concrete, longitudinal tensile stress at various temperatures, cracking and permeability tests on concrete, resistance to actinic rays) were conducted on a number of products with a view to selecting the most suitable. Details are given of the selected products, methods used in sealing works, observations carried out, and in-situ tests. Reference is made to the need for close cooperation between all parties concerned.
