Industrial Gutter Relining
The sites project management found Waterrail Roofing Services via our web site. We were called to site to advise on a possible solution to a totally failed gutter in the turbine hall of the power station. 52 Linear Metres of boundary gutter relined with H.G Sharman Ltd Rubberised plygene gutterline system. A galvanised steel flashing break pressed to match the existing profile was fixed in the sole of the gutter to prevent ponding and puncture by the existing totally failed gutter. 4no. outlets and 2no. stop ends and 2no. weir overflows were heat welded to the liner to create a joint and detail free gutter. Because the sole of the gutter was 500mm wide and the sites high exposure location holding down straps were also fixed at 2.0m centre to prevent wind uplifting the liner. Badly rusted roof sheeting which had been located beneath steam pipes were also overlaid with a matching profile and the total roof area was brush and petrol blower cleaned to remove an accumulation of debris.
The clients brief was to reduce Internal sound reverberation and increase thermal insulation values in their machinery assembly hall. We proposed the installation of 400 sq. metres of 100mm thick Rockwool high density RWA45 insulation slabs secured to the existing liner panel using self adhesive insulation pins. Then a fully perforated 0.7mm thick bright white liner panel was fitted to the internal face of the existing sheeting rails all ductwork, louvers, control panels and heat sensors were then trimmed with flashings.
Badly rusted roofing, cladding sheets and failed rainwater goods to lots of boiler rooms, small plant canopies and machinery enclosures were replaced using 600 Sq. metres of single skin profiled steel sheeting including new flashings gutters downpipes. Thes works were carried out in conjunction with other trades to take full use of the significant scaffold provided.
The power station had been in full operation for over a month when a fire broke out at the junction of the wall cladding with a large exhaust flue from one of the turbines in the Turbine Hall. We were called to site the day after the fire and started on site 3 days later to reinstate the wall cladding and insulation. A paper breather membrane, polyethene vapour check and 15 year old insulation quilt had burnt significantly within the existing twin skin build up. It was decided to replace all the cladding and insulation and remove all paper and polyethene to the elevation. 480 Sq. metres of single skin profiled steel sheeting was stripped and resheeted the insulation being changed to 50mm thick rigid insulation batts fixed with stick pins. The plygene gutter which had been installed on the 1st phase of our works at the site was also replaced due to fire damage. Internal liners around the vents where also opened up and ceramic fire blanket quilt was installed to offer a fire check.
