introduction

company credentials

Founded in 1901 H & R Johnson Ltd. is

the leading manufacturer and supplier of

ceramic tiles in the UK, with a long history of

market leadership and industry production

development.

Part of the Norcros Group we have sister

manufacturing bases in South Africa,

Greece and India with additional offi ces in

Dubai, USA and Australia.

In 2001 an investment in excess of

£35 million allowed us to develop a new fully

automated production facility on a single

integrated site in Stoke-on-Trent.

Our UK factory produces over 5 million

square metres of ceramic tiles for use in the

UK and overseas markets.

H & R Johnson products are used in a wide

range of commercial and non commercial

projects and we supply ceramic tiles to

almost every country of the world.

Our strength is based on a comprehensive

portfolio of leading edge quality products

combined with very high levels of

customer service. As manufacturers

we have extremely stringent quality and

environmental control standards.

pools - introduction

In 2006 we created and opened the award

winning Material Lab design resource

centre at 10 Great Titchfi eld Street,

London, offering designers and architects

an environment where products such as

ceramics, glass, wallpaper, carpet tiles,

trims, eco-resins, fabrics and many more

materials can be explored.

We have a longstanding commitment to

environmental management and have had

a formal environmental policy since 1992.

Our environmental management system is

certifi ed against the ISO14001 standard.

We were the fi rst ceramics company within

the whitewares sector to gain certifi cation

against the ISO14001 standard in 1998

and have since successfully upgraded our

certifi cation to meet the latest requirements

of ISO14001:2004. We are the only UK

wall tile manufacturer to have ISO14001

accreditation.

The company has never been subject to

any prosecutions or formal environmental

regulatory action for any breaches of

environmental legislation.

In 1997 H & R Johnson were awarded

the Queens Award for Environmental

Achievement for our ceramic waste

recycling scheme.

To our knowledge we are the only

manufacturer in the world to operate such

a scheme. This scheme which has been in

continuous use since 1992 also enabled

H & R Johnson to win the Manufacturing

Industry Achievement Award for

Environmentalist of the Year in 1997.

Approximately 25% of the material used to

produce our wall tiles comes from recycled

ceramic materials from our own and other

local companies.

Various recycling and energy saving

schemes throughout our production and

offi ce processes allow us each year to:

Save 20,000 tonnes of ceramic landfi ll from

our own and local ceramic factory waste

saving 360 tonnes of CO in transportation

2

of materials

Save 1250 tonnes of virgin timber

Use 92% recycled materials in our

packaging

Re-use 32 million litres of water (30% of the

total factory usage)

Save 42 million kWh of energy

Save 2400 tonnes of CO2 Our energy and material savings are

detailed in our “Ceramic Tile Environmental

Strategy” document.

pools

The Architectural range of swimming pool tiles are pressed glazed porcelain and offer much greater

accuracy of size and strength of body when compared to extruded swimming pool tank tiles.

The dimensional accuracy of the pool tank tiles allows creation of a 250 x 125 x 8mm standard module

with the incorporation of a 3mm wide joint. The use of a 3mm wide joint results in fi nancial savings on

installation and grouting costs. The package is supplemented by a comprehensive range of pool fi ttings

which allow the creation of almost any pool detail.

swimming pool setting out

The internal fi nished dimensions of

swimming pools are set by FINA (Federation

Internationale de Natation) for 50m Olympic

and World Championship pools and by ASA

(Amateur Swimming Association) for 25m UK

competition pools.

Length

Short Course Championships are swum over

a course of 25m but pools up to 33.3m are

also accepted. Long Course Championships

are swum over a course of 50m.

Width

Multiples of 2m (Short Course) and 2.5m

(Long Course) are recommended with an

additional 1m to allow for two 0.5m areas

outside the outer lanes. Short Course Pools

have a recommended minimum width of 13m

and a maximum width of 17m whereas Long

Course Pools are 21m and 25m respectively.

Depth

A minimum water depth of 1m is

recommended for Short Course Pools but

1.8m is preferred. Long Course Pools have a

minimum water depth requirement of 1.8m.

End Walls

Both end walls should have an anti-slip area

extending a minimum of 0.8m below the water

line to enable safe push-off.

Number of Lanes

A minimum of 4 and a maximum of 10 (even

numbers are recommended) for Short Course

Pools and a minimum of 8 lanes for a Long

Course Pool.

technical - setting out

Diving Pools

The ideal size of a diving pool is 32m x 21m

x 5.5m deep but other recommended sizes

are 25m x 20m and 25m x 16.5m. In practice,

though, the size of a diving pool is governed

by the size(s) of other pools in the complex.

Depths vary according to the height of the

highest springboard or platform to be used.

For springboards the minimum water depths

are:

1m springboard – 3.5m water depth

3m springboard – 3.8m water depth

For platforms the minimum water depths are:

1m platform – 3.3m water depth

3m platform – 3.6m water depth

5m platform – 4.0m water depth

7.5m platform – 4.5m water depth

10m platform – 5.0m water depth

The base of the diving pool should be in a mid

blue colour for best diver perception of the

water surface.

Water Polo

Minimum length, width and depth vary

considerably dependant upon the level of

competition being played. Indicators should

be located on both long sides, these can

be incorporated in the tiling scheme for

‘Freeboard Pools’. For goal lines and halfway

line a white marker is required (black can be

used as an alternative). Indicators 2m from the

goal line are to utilise a red marker, 4m from

goal line a yellow marker and the 7m shooting

line a green marker.

The details given are as H & R Johnson

understand them and must be checked with

offi cial sources prior to construction of the

Swimming Pool shell. Lengths noted above

are from timing pad to timing pad.

slip resistance

When specifying products for wet change

fl oors, shower fl oors or the area surrounding

a swimming pool tank (pool surround or pool

deck) aesthetics and ease of cleaning should

never override safety.

Correctly specifi ed, installed, cleaned and

maintained ceramic tiles will give a lifetime of

slip resistance surface provision.

Watchpoints

Floor fi nishes to wet barefoot areas (showers,

wet change facilities, swimming pool steps

and pool surrounds):

Must be slip resistant when wet and have a

non abrasive surface

Should be easy to keep clean so that the slip

resistance of the fl oor material is maintained

at all times

Should have a texture that is as comfortable

as possible for bare feet

Should be laid to falls

Should incorporate fl ush drain covers

wherever possible

Should use fl oor fi nishes that achieve either

category “B” or category “C” slip resistance

when tested by DIN51097 Wet Ramp Test.

(Category “C” has a greater slip resistance

than category “B”). In certain locations (pool

access steps wider than 1m, walk through

pools, pool surround ramps) only category “C”

is suitable

Falls in Floors

All fl oors in wet barefoot areas should be

constructed with falls to suitable outlets

to enable draining of water. HSE guidance

recommends that fl oors be laid to falls so

that the majority of the water drains away to

properly constructed outlets and recommends

the use of profi led tiles to allow the water

to collect in the low areas whilst leaving the

high areas relatively dry or at least above the

surface of the water. The degree of slope of

the fl oor depends upon numerous factors

but, as an example, a minimum fall of 1:50 is

recommended in the “Specifi ers Handbook

for Inclusive Design – Internal Floor Finishes”

available from RIBA bookshops.

Suitable Products

(general wet barefoot areas)

Products with category “B” or “C” slip

resistance which are detailed in our Kerastar

(Keramosaic, Gripfoot, Discface, Suretread,

Diamond or Rocktop), Elements (Sediments

Textured or Sediments Gritted) and Ceramic

Mosaic (Touchstone) brochures.

Suitable Products (submerged areas)

General Pool Floors

There are no agreed guidelines on the

degree of slip resistance for surface fi nishes

permanently submerged in water (swimming

pool tanks). Guidance is left to the experience

and advice of the product manufacturer,

supplier or installer.

Once the water has some depth, there is

an increased damping effect on the legs

which increasingly renders the concept of

slip resistance less and less relevant. Also as

water increases depth to 1m or so buoyancy

also has an effect.

H & R Johnson Tiles Ltd product

recommendations on slip resistance for pool

tank fl oors are:

Water depths from 1mm to 450mm (Beach

type Pools and very shallow Childrens Pools)

– minimum category “B” when tested by

DIN51097 Wet Ramp Test.

Water depths from 450mm to 850mm

(Childrens Pools or shallow areas of Main

Pools) – the above specifi cation or our gritted

pool tank tiles

Water depths over 850mm – the above

specifi cation or our plain gloss fi nish pool tiles

Codes of Practice

All fi xing of fl oor, cladding and pool lining tiles

should be in accordance with the following

codes of practice guidelines:

BS5385 Part 2 – 2006 (Code of practice for

the design and installation of external ceramic

wall tiling and mosaics)

BS5385 Part 3 – 1989 (Code of practice for

the design and installation of ceramic fl oor tiles

and mosaics)

BS5385 Part 4 – 1992 (Code of practice

for ceramic tiling and mosaics in specifi c

conditions) – includes swimming pool tanks

BS8000 Section 11.1 – 1989 (Workmanship

on Building Sites, Part 11, Code of practice for

wall and fl oor tiling)

Substrates – pool surrounds

For installation guidance on swimming pool

surrounds please refer to the installation

guidance in the Kerastar brochure.

Substrates – pool linings

Before tiling is commenced ensure that the

pool has been water tested and proved to

be watertight in accordance with BS8007,

clause 9.2 and that the pool shell and general

conditions are suitable before rendering and

screeds are applied or before tiling.

It must also be ascertained that the correct

minimum curing periods have been observed

for all substrates:

Completion of pool shell to commencement

of rendering/screeding/tiling (for direct to

concrete installation) – 6 weeks

Completion of rendering/screeding to

commencement of tiling – 3 weeks

Completion of tiling to commencement of

grouting – 3 days

Completion of grouting and sealing of any

movement joints to fi lling of pool – 3 weeks

28

technical - installation

Accuracy of the substrate must be checked

to ensure that the guidance given in BS5385

has been achieved i.e. “local variations in level

for a nominally fl at fl oor or wall should be such

that, when checked with a 2m straightedge,

any gap under the straightedge between

points of contact does not exceed 3mm”.

Movement Joints in Pool Linings

The location, type and scope of all movement

joints must be ascertained prior to any fi xing

works. Structural joints in pool linings are

uncommon but where they exist they should

be followed through to the face of the tile

at full width. Intermediate movement joints

(minimum 6mm wide) should be situated at:

Changes of plane (including internal wall/fl oor

junctions, fl oor/fl oor junctions and wall/wall

junctions)

Where tiling abuts other materials

Maximum 6m continuous bays along the pool

fl oor and up the pool walls

Intermediate movement joints in pool linings

are the thickness of the tile and adhesive

bed only.

Movement joints should be fi lled with a

suitable backer, bond breaker and fi ller

(check with movement joint manufacturer for

suitability).

Fixing Tiles

All pool lining tiles should be fi xed with a solid

It is good practice to periodically remove a

recently fi xed tile to ensure that the correct

bedding is being achieved and maintained.

When fi xing all tiles care must be taken

to ensure that no lipping of tiles occurs.

All pool tank tiles within this brochure are

recommended to be fi xed with a 3mm wide

joint. All pool fi ttings in this brochure are

recommended to be fi xed with a 3-5mm

wide joint.

Adhesives

Adhesives should be in accordance with BS

EN 12004, Class C2*. Particular adhesive

choice will be governed by the substrate.

* Check with adhesive manufacturer for

additional C1 product suitability.

H & R Johnson recommend the use of

Johnson Professional adhesives and grouts,

see below:

Grouts

The choice of grout should refl ect the

expected service conditions and water type of

the installation.

For pools in soft water areas grouts should

be class CG2 i.e. Johnson Professional No

Mould Flexible Grout. For pools in hard water

areas or areas of a pool lining where there is

aggressive water (pools with wave machines,

rapids areas or spa pools) grouts should be

class RG1 i.e. Johnson Professional Easy

Clean Epoxy.

please contact Johnson Professional helpline

cleaning and maintenance

Maintaining the appearance and

characteristics (especially slip resistance

values) of fl oor tiles is achieved with the

implementation of a suitable cleaning regime.

It must be stressed that the cleaning material

manufacturers instructions must be followed

at all times. Regular and correctly undertaken

cleaning should maintain a product as close

to its original state as possible. Incorrect or

infrequent cleaning will adversely affect the

properties of the tiles and increase potential

hazards.

Please see Kerastar brochure for specifi c

cleaning information for pool surround tiling.

Cleaning in pool linings can be split into

several categories:

Builders Clean

This should be undertaken prior to a fl oor

being brought into service. The builders clean

removes any residual fi lm left over from the

grouting operation and is a one off cleaning

process. It is imperative that this is carried out

as any grout residues left behind will act as a

key for dirt resulting in the installation being

diffi cult to clean.

Cementitious Grouts

The use of a mild acid decementing solution

followed by thorough rinsing will remove all but

the most stubborn of cement residues.

Epoxide Grouts

It is essential that ALL residue be removed

from the surface of the tiles during the grouting

process and before the resin cures. Failure

to achieve this will result in a very diffi cult and

expensive process using gel-type epoxide

removers.

Abrasive powders or cleaners should never

be used on ceramic tiles.

Correctly specifi ed and installed swimming

pool ceramics require little maintenance.

If there is need to empty a pool for major

refurbishment works the advice of pool

experts is strongly recommended prior to

emptying of the swimming pool.

Minor pool repairs can be carried out using

specialist diver repair teams. This removes the

need to empty and re-fi ll the pool, reducing

closure time, expensive water losses and reheating

costs.

To minimise the pool tank stresses during

emptying and fi lling the pool it is important

that:

The pool is fi lled or emptied at not more than

750mm depth per day.

The pool water is heated or cooled at no more

than 0.25ºC/hour.

dda - disability discrimination act

The Disability Discrimination Act 1995

(DDA) introduced new measures to prevent

discrimination against disabled people. The

Act was broadened in 2005 to form the

current Disability Discrimination Act 2005.

The DDA requires accessible environments

to be provided for disabled people, either in

their place of work or for access to goods,

services or facilities (public spaces). Those

commissioning new buildings or adaptations

to existing buildings must consider the

implications of the DDA and their ability to

provide buildings that do not discriminate

against disabled people (physical or mental

impairments).

When specifying ceramics there are 2 main

areas of relevance within the DDA.

30

Colour Refl ectance (Contrast)

The DDA gives guidance on good visual

contrast for the visually impaired between

various elements of a building by the use of

Light Refl ectance Values (LRV).

LRV is a general term for contrast and is

measured as the proportion of useful light

refl ected by a coloured object, fl oor, wall or

ceiling. LRV is measured on a scale of 0 to

100 where 0 is perfect black and 100 perfect

white (in reality 0 and 100 are unobtainable

colours). According to NCS Colour Centre in

practical terms black is approx 6 and white

approx 85. See page 44-47 for values.

The current guidelines from Building

Regulations Approved Document M on

contrast are that a minimum difference of 30

LRV points should be specifi ed for adjacent

surfaces to ensure that visually impaired

people are not discriminated against. In

the specifi c example of ceramic tiles this

difference should be between:

Floors to walls

Ceiling to walls

Handrails to walls

Sanitary fi ttings to walls

Visual contrast between fl oors and walls is

important in enabling visually impaired people

to assess and gauge the size and shape of a

room. It is important that the greatest visual

contrast occurs where the fl oor meets the wall

(skirting) as this gives the most accurate visual

indication of the extent of the room. Where

provided, skirtings should contrast visually

with the fl oor and be similar in colour and tone

to the wall surface.

Tactile Foot Braille (see Kerastar or

Elements literature for details)

Recommendations from the Department of

the Environment, Transport and the Regions

(DETR), the joint mobility unit of the RNIB

and the Centre for Accessible Environments

(CAE) led to the need for Tactiles to be used

as warning features for stairs, ramps and

platforms.

Available in 400x400x10mm format and in 2

colour options the Johnson Tactile System

offers compliance with not only the DDA

requirements but also the DETR, RNIB and

CAE recommendations. Specifi ed correctly

the Johnson Tactile System will ensure that

any new building Access Audits will be

compliant with the Access to Goods and

Services part of the DDA.

The Johnson Tactile System is manufactured

to the highest technical and performance

standards. The surface of the Tactile products

have the enhanced performance qualities of

a slip resistance durundum inclusion in the

surface of the tile.

The Corduroy profi le is designed to warn

visually impaired people of the presence

of specifi c hazards. Such a profi le is “Foot

Braille” and is a warning associated with

steps, ramps or the approach to on-street

light rapid transit platforms. The Corduroy

profi le is an internationally accepted Tactile

surface that conveys the message of hazard

and implies proceed with caution.

The Blister profi le is designed to warn visually

impaired people of the edge of all off-street

platforms. The profi le consists of a series of

offset, fl at topped dome studs. The parallel

rows of studs are designed to be installed at

right angles to the direction of traffi c and are

normally located behind the platform edge

coping.

This information is not exhaustive and the requirements at the time of specifi cation must be checked.

BS8300:2001 Amendment 1 indicates that there is anecdotal evidence to suggest that a 20 point LRV difference may be suffi cient –

especially where large adjacent areas are involved.

It must be noted that the guidance on LRV values given in this brochure is correct at the time of print. This is a subject that may be

reviewed by the regulatory body at any time so it is advisable to check the guidelines at the time of specifi cation of product.

The DDA details given in this brochure are to be used as an outline guide only and are the details as H & R Johnson understand them

at the time of print. If in doubt of any details contained herein the Act should be read in full.
