Denso™ Protection System for National Grid LNG Tank Bases
Winn & Coales Denso™ Tank Base Protection System is being used at the Isle of Grain National Grid site on four of their LNG storage tanks. The installation work was carried out by contractors JPV Painters of Brentwood.
To meet various operating conditions at the Isle of Grain National Grid site, the Denso Tank Base system was chosen to give effective protection.
Following surface preparation, Denso Hi-Tack Primer™ and Denso Primer D™ were applied. Densyl™ Mastic was then applied in the gap between the tank and the base. This not only provides a sealant between the concrete and tank base to prevent entrapment of water, but also a smooth profile when applying the following Denso Hi-Tack Tape™. A single layer of Denso Ultraseal RT Tape™ was applied and then finally a topcoat.
The Denso Tank Base Protection System is flexible enough to move with the tank when it gets filled and emptied and provides a tough outer armouring. The highly weather resistant system provides a long-lasting solution to Tank Base problems.

Denso™ Corrosion Prevention for Wessex Water Pipe Fitting
A Wessex Water pipe-fitting has recently been wrapped with the Winn & Coales Denso 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 because the products meet the requirements of the CESWI P1 Specification for Water Industry. The corrosion prevention system comprises Denso Paste™, Denso Profiling Mastic™ and Denso™ Petrolatum Tape.

Densoseal 16A™ Chosen for Thames Water Cable Entries
Flood Control International of Tavistock, Devon, are completing a project at a Thames Water site near Maple Cross, Berkshire involving sealing cable entries with Winn & Coales Densoseal 16A™. There will be further Thames Water sites to follow in a major refurbishment of their sites resulting from a Flood Prevention report.
Densoseal 16A is a non-setting, self-supporting mastic which may be applied to wet surfaces and will seal ducts and conduits against ingress of water and gas. It is suitable for CHP and biogas projects. It complies with British Telecom Specification M212C. It is suitable for sealing cable ducts, conduits and service entry pipes or sleeves, particularly below ground level, to prevent entry of water or gas into buildings. It may also be used for profiling mechanical joints on hot pipes to allow application of tapes.

Denso Steelcoat™ Protects Newquay Private Suspension Bridge
If your home is the beauty of an island, connected to the Cornish coast by a suspension bridge, you have few problems – but one of the biggest is the corrosive marine atmosphere. When the owners of The Island in Newquay were planning maintenance work on their private footbridge they wanted to use a product which would give the steel cables long-lasting protection against the harsh coastal elements.
Winn & Coales (Denso) Ltd were contacted to meet this challenge and advised the use of their Denso Steelcoat 100/400™ system. Denso Steelcoat™ Systems provide a cost-effective, long term solution to corrosion on exposed steel and can provide many years of maintenance free service life.
After surface preparation, Denso Hi-Tack Primer™ was applied, followed by Densyl™ Profiling Mastic for filling awkward profiles. Denso Hi-Tack Tape™ was then applied, followed by Denso Ultraseal Tape™ and finally painted with Denso Acrylic Topcoat™.

Densostrip™ Used On Refurbished Ross Fountain
As part of a recently completed £1.5million project to refurbish the historic Ross Fountain in Edinburgh, Winn & Coales (Denso) Ltd supplied Densostrip™ and Densostrip™ Primer to seal between precast concrete units supplied by Creagh Concrete Products Ltd.
These precast units form the trenches which house the underground supply of services to the fountain. They were installed by Creagh Concrete Products.
The year-long restoration project on the new foundations and waterworks (under the Ross Develoment Trust) now enables the fountain to operate for the first time in years. Industrial Heritage Consulting Ltd were the project managers on the fountain conservation works.
The elegantly refurbished Ross Fountain stands at the foot of Edinburgh Castle.
