Glue laminated poles - Progress report after 12 years' testing

IRG/WP 92-3685

J Jermer, Ö Bergman

In 1979 a number of glued laminated poles treated with CCA and creosote were placed in a greenhouse at Uppsala, at the Simlångsdalen test field in southern Sweden and under a power line just south of the Arctic circle in order to study their resistance against biological degradation. The tests have shown that the comparatively best performance will be obtained if each laminate is first treated with a water-borne preservative (only CCA was used in this test) and thereafter the laminated pole treated with creosote. These poles are after 12 years' exposure in the field still free from decay.
