London Underground Ltd

TM144:1999 Modified Standard
"When moving around the pedestrian environment, visually impaired people will actively seek and make use of tactile information underfoot. It is therefore important that textures warning of potential hazards ... are rigorous enough to be detectable by most people but without constituting a trip hazard or causing extreme discomfort."

Safety Flooring

The message from the Health and Safety Executive is clear: slips and trips are bad for people and damaging for business.

Personal injuries such as fractures, burns and worse can result in pain and days off sick. Businesses suffer from staff being away from work and potential hefty insurance claims against them for causing the injuries. Contributing factors to slips include unsuitable or wrongly specified flooring, contamination, spillages and poor housekeeping. Universal accessibility requirements mean that premises which are places of work and also other non-domestic premises have to be safe for all people including wheelchair users, people with limited mobility and those who have visual impairments.

Reducing as many risks for slips and falls as possible is in everyone’s best interests. Specifying the right floor materials for new buildings as well as modifications, extensions and conversions is a good place to start.

Which type of safety flooring?

That’s a big question. The answer depends on so many factors: Where is it being installed, who will be using it and what will they be doing there? Is it inside or outside or is it for an entrance? Will the conditions be dry or wet or both? Are there ramps and/or stairs involved? The list goes on.

Dorset Quarry Tiles

Dorset Woolliscroft tiles, tactiles and fittings are specifically designed as technical flooring tiles. There are a range of finishes for different environments, from those suitable for wet barefoot areas (such as around swimming pools and changing rooms) to tiles with enough abrasiveness to be suitable for steps and ramps in all-weather locations (such as busy railway walkways, overhead bridges and concourses).

Movement Joints

For interior or exterior floor tile installations, movement joints should be located:

  •  over existing structural movement joints
  •  around the perimeter of the floor and where tiling abuts columns, curbs, steps and plant fixed to the base
  •  in large floor areas tiling should be divided into bays not exceeding 8-10m intervals. On suspended floors the bay size should be reduced and additional joints provided over supporting walls and beams

All floor tile joints should extend throughout the depth of the tile, bed and screed and should be 6-10mm in width.

They should be designed to avoid being subjected to the effect of wheeled traffic and where this is not possible metal reinforced joints should be specified.

Grout: highly pigmented grout may stain the tiles. Always test before installation.

After Fixing

It is the responsibility of the owner to provide for routine inspection, appropriate maintenance, and to assure compatibility of all cleaning methods/ products with grout and mortar manufacturers. Appropriate maintenance requirements are determined by the site environment and the specific use of the installation. All damaging contaminants must be removed from grout joints sufficiently and regularly to avoid permanent damage from exposure to food, biological waste, industrial chemicals and aggressive cleaning solutions. Consult manufacturers for recommended procedures.

They should be designed to avoid being subjected to the effect of wheeled traffic and where this is not possible metal reinforced joints should be specified.


Newly Laid Floors

There may be residual cement on the tile surface of newly laid floors. All traces of this must be removed by applying a mildly acidic decementing solution, which must be rinsed off thoroughly. Clean regularly as specified below.

Regular Cleaning

Regular cleaning with warm water (or hot water for oil and grease) and a neutral or mildly alkaline (pH to 8) detergent will remove all but the most stubborn dirt. Mix the detergent as recommended by the manufacturer. The water/detergent mixture must be left on the floor for enough time (5-15 minutes) to allow it to penetrate and emulsify the dirt. Rinse thoroughly with clean water to remove all traces of the detergent mixture.

Large areas of plain or textured surface tiles are best cleaned with rotary, cylindrical or reversing mechanical scrubbing machines as follows:

  1. Use slow to medium speed rotation. If the machine has a suction drying facility, use it first with the suction facility switched OFF. This permits the water detergent mixture used in the scrubbing process to remain on the floor to penetrate the dirt layer.
  2. Leave for at least 5-15 minutes to elapse, then repeat the scrubbing operation with clean water only and with the suction drying facility switched ON. It is the rinsing process which removes the dirt.
  3. Spillages of oil, fat or any material likely to stain or cause a slipping hazard should be removed immediately by using detergent and hot water, followed by a cold water rinse.
  4. Use warning signs or physically exclude people from wet cleaning areas until they are completely dry.

Longer Term Maintenance

Clean the floor periodically using a rotary, cylindrical or reversing scrubbing machine with the addition of an abrasive powder or fine Silica Sand. These products scour the tiles, remove impacted dirt, and generally refresh the floor without damaging their surface. Remove the residue with clean water and rinse before it can dry out. If high velocity water jets are used for removal of stubborn dirt this will not damage the tiles, but may erode the joints if used regularly. If oil or grease is present, use the jet with warm or hot water and with a pH neutral detergent.

Please note that marks made during installation and with constant use may be more obvious on pale colours. Therefore even Dorset Woolliscroft fully vitrified tiles will require a certain amount of extra cleaning in areas prone to heavy soiling.

NB. These cleaning and maintenance instructions are Dorset Woolliscroft’s recommendations and not necessarily exhaustive. The recommendations of manufacturers of cleaning equipment and materials should always be followed.
