Quadriga, working for Laing O’Rourke, have been contracted over three months to clean and seal 6000 m2 of the Southside and Eastside facades belonging to Imperial College in Princes Gardens, London.

Quadriga offers many different types of cleaning processes, each designed to produce maximum results on the particular surface being cleaned, and which include most stonework, brickwork, granite, faience, terra-cotta, concrete rendering, marble and mosaic. Mortar residue, organic growth and engrained industrial deposits are often difficult to remove from stone and brick surfaces, especially if they have become established over large areas and considerable periods of time.

The most used cleaning processes are mason and nebulous spray water, controlled wet and dry grit blast, low pressure wet abrasive and specialist processes employing strong cleaning agents in conjunction with high pressure water cleaning.

The materials specified for use at Imperial College were antimousse fungicide and protectguard sealer manufactured by Guard Industries and Quadriga are approved applicators of these products. Also specified within the project was the cleaning and sealing of the Granite paving including the lobby areas as well as locating isolated poultice applications to remove all visible ‘rusting’.

Following all the cleaning and repair operations, Quadriga carried out preservation treatment by applying specialised water repellent and preservative.     

                                           

Quadriga is one of the leading UK specialists in the conservation, restoration, structural repair and refurbishment of buildings and structures.
