Dublin's New Central Plaza Conversion Uses Denso Protection
The old Central Bank Building in Dame Street, Dublin, is currently being redeveloped and will reopen as the Central Plaza consisting of offices, shops and restaurants. Winn & Coales (Denso) Ltd are supplying corrosion prevention coatings for major structural sections and also an outer wrap prior to fire protection.
The building was originally constructed in the 1970's and the design was based on suspending each floor from two large concrete cores. Each floor level was then constructed at ground level and hoisted into place and then supported by Macalloy tension bars.
DBFL Consulting Engineers in discussion with Winn & Coales decided to remove the existing wrap and apply Denso Tape™ to 2500m of 40mm Macalloy bars, thus providing long term corrosion prevention. Denso Self Adhesive PVC Tape™ was then used as an outer wrap before fire protection and cladding was applied.
Aberdeen Marine Choose SeaShield 2000FD ™
When Aberdeen Marine Ltd were awarded the contract to protect six piles on the Eriskay
Causeway Bridge in the Western Isles they suggested the use of the Winn & Coales (Denso) Ltd
SeaShield 2000FD ™ System as an alternative to the original specified system.
They submitted details of the technical merits of the SeaShield 2000FD™ system and the benefits in using this tried and tested system to the Western Isles Council, who agreed to the change in the specification.
Despite the challenges of the remote location and inclement weather conditions, Aberdeen Marine Ltd completed the application during the winter months.
Seashield 2000FD ™ is a heavy duty robust system which provides protection against corrosion
on Marine piles. It consists of Denso S105 Paste™, Denso Marine Piling Tape™ and a HDPE Jacket which is applied by pneumatic tensioning equipment and secures with stainless steel bolts.
Denso™ Steelcoat™ Protects Ayr Pipe Crossing
George Leslie Ltd recently carried out a contract for Scottish Water to remove sections of an existing coating and carry out Non Destructive Testing on a Pipebridge near Ayr. After the testing was complete these areas were then protected with the Denso Steelcoat 100-400 System.
Having examined the system applied to the test areas, Scottish Water then decided that as scaffolding was already in place they would take the opportunity to wrap the whole section of pipe which crossed the River Ayr.
Denso Steelcoat 100-400 System consists of Denso Hi-Tack Primer, Denso Profiling Mastic, Denso Hi-Tack Tape, Denso Ultraseal Tape and Denso Acrylic Topcoat. It is designed to provide long term corrosion protection with minimal surface preparation therefore making it ideal for use in remote areas where prevention of contamination to the surrounding environment is important.
Denso™ Corrosion Prevention for Wessex Water Pipe Fitting
A Wessex Water pipe-fitting has recently been wrapped with the Denso TM P1 System. The project in Warminster was to install a new pipeline to a pumping house, replacing an old existing pipeline which will now be discontinued.
The Denso P1 System was selected as a result of their products meeting the requirements of the CESWI P1 Specification for Water Industry. The corrosion prevention system comprises Denso Paste, Denso Profiling Mastic and Denso Petrolatum Tape.
Densostrip™ Used On Refurbished Ross Fountain
As part of a recently completed £1.5million project to refurbish the historic Ross Fountain in Edinburgh, Densostrip™ and Densostrip Primer™ was supplied to provide a permanently watertight seal between precast concrete units.
Densostrip Seals Hinckley North Berth Surfaces
Construction is well underway by Costain on the North Berth project that will serve the forthcoming construction of the Hinckley nuclear power station. Precast concrete units are being applied to the surfaces of the North Berth. As can be seen in the photo, within the black circles, Densostrip is used to permanently seal the concrete units following application of a special primer
Densostrip is a compound rubber and bitumen joint sealing strip specifically for precast concrete units to provide a permanently flexible watertight seal when compressed between joint faces previously primed with Densostrip primer. As well as water and sea water it is resistant to chemical and biological attack. It is also an effective seal for precast concrete box culverts, manholes, inspection chambers, shafts, tunnels and pipe sections.
Denso System Used on Irvine Trunk Main
An aging water main located near Irvine, Ayrshire, was identified by Scottish Water as needing replacement in 2017. The current pipeline, which supplies over 40,000 customers in the region, was to be replaced with a new 12km stretch of polyethylene pipeline. The contractor are Caledonia Water Alliance. A Denso P1 Specification System was selected for the protection of various ductile iron fittings on the project as a result of their products meeting the requirements of the CESWI P1 Specification.
The specifications state that a petrolatum paste (Denso™ Paste) shall act as a primer and cover all areas to be protected. A smooth external profile is then created with the use of a profiling mastic (Denso™ Profiling Mastic) to cover any projections from the pipework. Finally, the profile is spirally wrapped with a protective tape (Denso Tape™) using a 55% overlap.
For extra security on this project, Denso SA PVC Outerwrap™ was used to seal the system and protect the exposed petrolatum tape from UV or any backfill damage.
Denso Protection System for Hereford Water Pipeline
Lewis Civil Engineering is currently constructing an 8km length water main pipeline in Hereford for Dwr Cymru Welsh Water.
Winn & Coales (Denso) Ltd were contacted for information on the most suitable anti-corrosion system along with application training of Lewis Engineers for the pipeline's Viking Johnson joints. The selected Denso system meets the P2 Civil Engineering Specifications for Water Industry and consists of Denso Primer D™, Profiling Mastic and 150mm width Densoclad™ 70 Tape. Denso Profiling Mastic is a vital part of the system, it is applied to seal the voids, bolts and heads around the joints to avoid moisture entrapment. The Densoclad™ Tapes consist of a thick polymer-bitumen adhesive, giving superior adhesion and flexibility, laminated to a tough plasticised PVC backing.
It is expected that Lewis Civil Engineering will install more than six hundred 700mm by 600mm joints and nearly two hundred 700mm diameter Viking Johnson joints. In addition to this there are six 450mm diameter spigot & socket joint pipes. All pipe lengths and joints were supplied in new condition, so no blasting pretreatment was required.
The Denso materials were supplied via Burdens Civil Group, Merthyr Tydfil.
Denso Steelcoat Protects Scottish Water Pipes
The Denso Steelcoat 100-400 System has been used to protect two water pipes below a footbridge which crosses a small stream at Scottish Water's Killylour Water treatment Works, in Dumfries & Galloway.
