Case Studies

Jesus College Cambridge

Jesus 8Jesus 7

Architects Niall Mclaughlin are a practice that puts a strong emphasis on the inventive use of building materials, the qualities of light and the relationship between the building and its surroundings.  At Jesus College Cambridge, the project was to refurbish and extend a Grade II listed building and  staying within the historic footprint of the building was a key requirement.  Oak, stone, brick and quarry tiles were chosen as a consistent pallette of materials throughout the project, unifying the refurbished elements with the new build and all perfectly suiting the historical context of the site. Light multi brick sized Ketley quarry tiles were used in the new cafeteria pavilion where they help to merge the  internal and external spaces.  Their natural clay tones bring a richness of colour to both the inside and outside spaces and compliment the untreated oak frames and columns.  RIBA National Award winner 2018 .  

Cabinet Gallery Tyer St London

Cabinet Gallery 3Cabinet gallery 2

Trevor Horne Architects worked collaboratively with Charles Asprey and the gallery directors, plus a number of their artists to develop the design for this bespoke gallery space that would give a permanent home to the world renowned Cabinet Gallery.  The result is a 12 sided brick building arranged over 5 floors on the site of a former pub,  at the entrance to the Vauxhall Pleasure Gardens.  Aaron Down at Trevor Horne Architects chose to use authentic clay quarry tiles both inside and outside the gallery as their natural colour complimented the Petersen handmade bricks used for the gallery building.  After looking at  samples, he selected the light multi for its variety of natural tones.  The gallery has been awarded 2017 RIBA London Award.

Laying

Laying Quarry tiles

Download Ardex guide to fixing Dreadnought Quarry Tiles

During the floor laying operation the areas being treated should be accessible to no-one but the floor layers and should not be subjected to traffic until the bedding has stiffened and sufficient bond has developed between the bedding and the tile.  The floor should be kept clean and free from cement and plaster droppings.

As a general guide the following fixing should be followed;

  1. A joint width of between 6 & 10 mm

  2. A bedding layer to be approximately 6mm for cement based adhesives, 15-25mm for cement mortar and up to 70mm for a semi dry bed.

  3. A screed would normally be applied with a thickness of 50mm.

  4. A separating layer may be used to isolate the slips or paving tiles and their bedding from the base, preventing stresses in the base affecting the floor finish.  This method is not recommended for exterior applications.

When a screed is applied, the concrete base must be at least 4 weeks old.  The screed must then be allowed to mature for at least 2 weeks before fixing commences, during which time it must be protected from rain and frost.

Bedding directly to the base can be used where the base is completely matured and where there is no risk of further shrinkage movement or where a damp-proof membrane is incorporated between the concrete base and screed.  This method is suitable for external applications.

Care should be taken to incorporate appropriate falls and movement/expansion joints within the design of structure.

A suitable damp-proof membrane should be incorporated in the construction.

Quarry tiles should only be laid on a rigid bed with no voids underneath so the load applied to them is transferred through to the base.  In situations where heavy loads are involved the strength of the installation can be improved by the use of a thicker paver as the transverse breaking load of a clay paving product is directly related to its thickness where all other factors are equal.  It is advisable to select the material to resist the most arduous conditions likely to be imposed during the life of the product.

 

Grouting

Grouting of Quarry tiles laid with wet cement-sand mortars or adhesives should not be carried out for 12 hours after laying the quarry tiles. Where a semi-dry mix method is used, tiles should be grouted within 4 hours of laying to ensure a full bond between the grout and the bedding.

Board should be laid over the tiled area to spread the load of the tiler when carrying out the grouting operation. The grouting mortar should be adapted for the width of the joint with a lower ratio of cement for wider joints. A mixture of 1:1 cement to fine dry sand by volume mixed to a paste with only the minimum of water for workability, should be used for joints of less that 3mm and a ratio of 1:3 for joints wider than 6mm.  Avoid too wet a mix, as this will dry out rapidly and the grouting will crack and break out. Work in the grout in small joints with a squeegee action. In wider joints pointing is recommended.  After the joints have been filled, scatter a dry 1:3 or 4 mortar mix over the joints: allow to dry for about 5 to 10 minutes, then brush away excess loose material with a soft bristle brush. Finally clean off the tiles with water and a cloth, avoid excess watering of the tiles in this operation.

If an impervious joint is required, additives may be used in the grout mix or proprietary ready grouts can be used. However advice should be sought from the manufacturers as to their suitability for the application.  Attention should be paid to cleaning any proprietary grout or grouts mixed with additives off the surface of the Quarry tiles immediately.

Tiles should be cleaned as work proceeds. Such cleaning should be minimal with good workmanship.

Cleaning

Cleaning Quarry Tiles

Download our guide to laying and cleaning Quarry Tiles

Under normal circumstances Quarry Tiles require little maintenance and can be kept clean by sweeping then washing with warm water to which a suitable non-soapy detergent has been added.

Clean and dry flooring surfaces possess a low slip potential, the majority of slip accidents occur in the presence of a contamination between the floor surface and foot. The likelihood of a slip occurring is greatly reduced if contamination is controlled by means of a cleaning and maintenance procedure. In order for a cleaning and/or maintenance regime to be effective there are a number of basic elements that should be considered:

  • Before establishing a floor cleaning protocol, the specific contaminants must be identified in order to enable the selection of the appropriate cleaning agent

  • The cleaning tools provided should be appropriate for use with the floor in question ­ it may be necessary to assign dedicated tools for specific areas

  • Regular cleaning of the floor should be scheduled, specifying the responsible person and time of day or night (dependent on likely volume of pedestrian traffic) cleaning should take place

  • Clear instruction should be provided as to the cleaning requirements and procedures, correct use and disposal of detergents, emergency conditions and procedures and recording and reporting of maintenance operations

  • Wear, damage, debris and contaminants should be identified through routine inspection of floor surfaces.

Contamination cleansing routines are dependent upon a number of factors including the type of surface to be cleaned, the contamination present, the availability of chemical cleaning agents and the practicality of manoeuvring cleaning machinery in the given space. Beyond the method used, it is imperative to ensure all contaminates are removed following the cleansing process  The freshly cleaned floor must be thoroughly rinsed with clean water to make certain that all cleaning agents are removed and the floor is dry on completion. Failure to conduct these last actions can lead to a build-up of concentrated contaminate and cleaning agent on the surface of floors. These contaminant and cleaning agent residues will combine with any water subsequently applied to form an emulsion that can spread over the floor’s surface, significantly increasing the slip potential.

Quarry Tiles should require only a small amount of cleaning on completion, and this only when the joints are hard.  This should be done with a non-soapy, neutral, sulphate-free detergent and cleaned off with clean water. Strong detergents should not be used as they can cause scumming.  Always damp tiles before applying a cleaning agent to avoid the cleaner being drawn into the body of the tile: the cleaning treatment is then restricted to the surface of the tile.

Difficult stains can be removed in one of three ways;

  • By the use of an abrasive soap.  Steel wool should not be used as small particles ma be deposited in the grouting causing rust marks

  • By chemical means, by reaction with the appropriate solvent but due to the variety of materials that may cause staining it is recommended that advice is sought from organisations such as Lucideon in Stoke on Trent.

  • By bleaching to remove the colour from the stain, although this should not be done on a regular basis.

NB: The use of sealers and polishes on Quarry Tiles can make regular cleaning more difficult.
