Jesus College Cambridge

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 .

Laying Quarry tiles

Download our guide to laying and cleaning Quarry Tiles

Quarry tiles should be laid on a rigid base, with no voids underneath so that 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.
For a sand and cement base, allow at least 3 weeks before fixing the tiles. and for concrete, at least 6 weeks, preferably 12 weeks drying time should be allowed.
The surface should be hard, sound, clean, free from laitance and dust.  
It should also be flat with a tolerance of ≤3 mm under a 2m straight edge. Any deviations from this should be corrected using a levelling compound.

Under Floor Heating
Ketley Quarry Tiles are fully compatible with both water‑based (wet) and electric (dry) underfloor heating systems. Their dense, extruded clay body provides excellent thermal conductivity and heat retention, making them suitable for internal floors where UFH is installed beneath a screed or adhesive bed.

Fixing
Ketley recommends using a tile adhesive such as ARDEX X 7 R.  (Download Ardex guide to fixing Ketley Quarry Tiles) This adhesive is mixed with clean water and applied to the substrate with a suitably sized notched trowel to form straight, ribbed lines.  The quarry tiles are then pressed firmly into the adhesive bed at consistent joint widths (6-10mm).  The backs of the tiles should be regularly checked to ensure that solid bed fixing has been achieved.

Grouting

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

Ketley recommends using a flexible grout which is available in a wide range of colours from companies like ARDEX.  This product is mixed with clean water to a creamy consistency and worked thoroughly into the joints using a rubber squeegee.  As the work proceeds, any excess grout should be removed, residues can be removed with a damp sponge for up to 30 minutes.  Any dry film can be polished off with a clean cloth afterwards. If, after this process, there is a hazy mist on the surface of the tiles, this can easily be cleaned off with a grout remover, diluted according to the maufacturer’s instructions. 

Movement Joints
These should be installed in accordance with BS 5385‑3:2007.  Any existing movement/structural  joints should be continued through to the surface of the tiling.

Cleaning and Maintenance

CLEANING & MAINTENANCE
Ketley Quarry Tiles require minimal routine maintenance. Floors can usually be kept clean by sweeping to remove loose dirt, followed by washing with warm water and a non‑soapy, neutral, sulphate‑free detergent. Clean, dry surfaces have a naturally low slip potential; most slip incidents occur when contaminants remain on the floor, so an effective cleaning regime is essential for both appearance and safety.

ESTABLISHING AN EFFECTIVE CLEANING REGIME
- Identify contaminants so the correct cleaning agent can be selected.
- Use suitable tools, with dedicated equipment for specific areas if required.
- Schedule regular cleaning, assigning responsibility and timing around pedestrian traffic.
- Provide clear instructions on procedures, detergent use, disposal, spill response, and record‑keeping.
- Inspect floors routinely to identify wear, damage, debris, or contamination.

CLEANING METHOD
Cleaning methods vary depending on contamination, surface profile, available agents, and whether mechanical equipment can be used. Regardless of method, all residues must be removed. After cleaning, rinse thoroughly with clean water and leave the floor dry. Failure to rinse can leave detergent or contaminant residues that emulsify when re‑wetted and increase slip risk.

INITIAL CLEAN AFTER INSTALLATION
Once grout joints have hardened, tiles may require a light clean using a neutral, non‑soapy, sulphate‑free detergent, followed by rinsing. Strong detergents should be avoided as they can cause scumming. Tiles should be pre‑dampened before applying any cleaner to prevent absorption into the tile body.

REMOVING DIFFICULT STAINS
- Abrasive cleaners, avoiding steel wool, which can leave metal particles that cause rust staining.
- Chemical cleaning using an appropriate solvent; specialist advice may be required for specific stains.
- Bleaching, where suitable, to remove the colour of the stain.
NB The use of sealers and polishers on quarry tiles can make regular cleaning more difficult.
