Filling of first River mattresses proceeding – 30 September 2011

[vc_row][vc_column][vc_column_text]Rock for mattresses are also 100-67% of layer depth, so 200mm for the 0.3m depth. The mattress thus has at least two layers of rock to prevent soil scour in the event of high water velocities. Mattress lids are supplied separately so as to have them out of the way during infill of rock. From a labor point of view we allow 1.0m3/man per day for gabions and 1.5m3/man/day for mattresses, as mattresses have now bracing and neat front facings that need to be maintained.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][jig_vc][justified_image_grid row_height=250 height_deviation=50 caption=off overlay_icon=on orderby=menu_order filterby=off filter_style=buttons filter_orderby=title_asc last_row=flexible load_more=click load_more_text=”LOAD MORE” load_more_count_text=none load_more_mobile=no initially_load=12 load_more_limit=6 ng_gallery=30][/jig_vc][/vc_column][/vc_row]
