This additional protective coat is used in particular for the pipe jacking and horizontal drilling method (HDD). The GRP coating applied in the factory is convincingly effective due to the use of polystyrene-free resins and the fast curing by means of controlled UV light.[/vc_column_text][vc_row_inner css=”.vc_custom_1553693774494{margin-top: 30px !important;}”][vc_column_inner width=”1/3″]
