Denso Void Filler Aids Corrosion Prevention At Aberdeen Harbour

Denso Void Filler In Aberdeen HarbourThe main contractor was McLaughlin & Harvey from Belfast.

An integral part of the quay construction is formed by ten metre horizontal tie-bars which are cast into a structural concrete slab located four metres below the finished surface. The bars protrude through the main quay wall formed by sheet piles and act as a fundamental component of the structure, thus requiring protection from the harshest marine conditions.

In order to deter corrosion and help elongate the structures life span it was a design requirement to conceal the exposed ends within steel cylinder caps and provide an anti-corrosion void filler compatible with the cathodic protection system.

McLaughlin & Harvey sourced Winn & Coales (Denso) Ltd’s Denso Void Filler from local stockists, SIG Construction Products of Perth, and acquired approval by the consultant designers Arch Henderson for use.

Winn & Coales Denso Void Filler is based on a microcrystalline petrolatum containing corrosion inhibitors and moisture repellents. It forms a permanently flexible medium for the encapsulation and protection of bearings, tendons, stay cables, etc. It has been used on a variety of major civil engineering projects, including both Severn Bridges.
