Paving the way

Paving

Create unique forms and features to

complement structures and landscapes

alike with Blanc de Bierges setts.

Resembling traditional cobblestones,

they have the added advantage of

having a completely flat surface - more

comfortable and less hazardous for

pedestrian traffic. Subtle texture can be

incorporated by using either a fine or

striated finish.

In tapered form, they represent complete

flexibility, accommodating contour and

curve with ease.

For semi-industrial applications, our

straight edge setts are more appropriate.

Our complimentary range of fill in

pieces allow patterns to be varied where

interest or relief is desired.

They can be laid with or without mortar

joints depending on the look to be

achieved. Based on either 140mm or

150mm modules, the setts can be used to

co-ordinate with other products in our

range to create harmonious schemes.

Manufactured with the same exacting

standards, the Blanc de Bierges modular

slab range offers ample scope for design

for commercial and domestic schemes.

Available in a range of shapes, sizes and

thicknesses they are particularly suited

to terraces, paths and walkways as well

as pool surrounds and concourses.

The modular sizes are designed to

provide designers with pattern options

to suit the scheme. The slabs are equally

well suited to roof gardens and more

unusual applications. In this application,

a careful preparation of the underlying

bed - to create stability - is fundamental

to producing a unique installation.

5Copings & Kerbs

The perfect finish to a paved area or a

pool - wall top or feature, our vast range

of copings and kerbs are designed and

cast with meticulous detail to ensure

seamless integration with the Blanc de

Bierges range.

Options include straight, rounded or

chamfered edges - together with drip

edges if required.

Edges can be dressed on three or four

edges, to make a pillar coping for

example. The edges of square units can

be dressed on two adjacent sides as the

scheme demands.

In addition, special tapered kerbs can

be specified . These are particularly

useful for the edges to lawns where

damage from lawnmower blades can be

minimised - another example of the keen

attention to detail that comes with every

Blanc de Bierges component.

On the edge

Carefully designed to incorporate a non-slip surface yet still be

comfortable to walk on in bare feet, our pool surround tiles come

in over 3,000 variants.

Manufactured to lay correctly around a pool edge, our products

feature a selection of corner radii - to give swimmers a firm and

safe grip when entering or leaving the pool. Various internal and

external corners can be used to create unique shapes. Our range of

shutter covers ensure that the mechanical aspects of pools can be

dressed in harmony with the overall scheme.

Pool surrounds popular modular sizes include castings for:

Rectangular pools - inclusive of inside & outside cornersCircular pools - from diameters 2m to 12m

Walling & Retaining

Perhaps the most versatile component available to Architect’s,

Landscape Architects and Designers alike, Blanc de Bierges U

and L shaped modules can be used to create almost any feature.

From Retaining walls to steps, Planting tubs to Balustrades, their

flexibility allows them to be incorporated into both modern and

classical schemes.

Our L shaped modules are usually hand finished on the outer

surface only lending themselves equally well to retaining walls

or steps. For more unusual applications, they can also be finished

on both sides - making them more uniform in dimensions. In

this specification, they are well suited to seating areas and street

furniture, where their flexibility can be exploited to outstanding

effect.

L Modules

available in a range of popular sizes:

From 600mm x 400mm x 600mm x 50mm

Raising the game

Elegance with practicality is

demonstrated throughout the Blanc de

Bierges range of step solutions.

With 4 riser heights and over 80 varieties

of step, we can provide attractive

solutions for any environment.

The hand finished surface affords a

natural grip but for specific applications

we can provide a number of tread grip

options including high visibility for

partially sighted pedestrians.

Traditional stepsFormed from separate tread and risers,

these can be employed in harmony

with slabs and other Blanc de Bierges

products to create unique installations.

Integrated steps Using a combined tread and riser,

a seamless flow of steps can be

constructed. In addition, special small

steps with straight or tapered edges are

available enabling a free form approach

for designers. Used in conjunction with

slabs, curved steps and tree surrounds

can be accommodated.

Steps

Radial steps Integrated tread & riser Traditional steps

Radial stepsRadial designs can provide grand entrances or practical pedestrian

traffic management. Available with non-slip and high visibility nosings

they can be formed from traditional tread and riser sections or for a

more fluid design - modules can be specified. Tapered and straight edge

options can be combined to accommodate almost any radius or curve.

9

Cladding

Blanc de Bierges products can provide an

excellent contrast to brickwork, renders

and other types of masonry. The warm,

subtle colour can be used to complement

walls and vertical structures. The

consistent integrity of our products

ensures that it can be easily combined

with brackets and cladding retaining

systems.

Fine manufacturing standards and

tolerances offer scope for almost limitless

surface decoration.

Cladding

A wide number of unit sizes can be

accommodated for cladding purposes.

our spirals can be specified with either

one of two different treads per turn and

over 11 different radii. This provides the

ultimate in flexibility giving you freedom

to explore the design possibilities.

Landings and top steps allow seamless

integration with the surrounding

environment.

A stunning feature in any environment, a Blanc de Bierges spiral staircase is a classic

example of the skills and technical abilities of our craftsmen and our state of the art

manufacturing capabilities.

Manufacturing

Investment in research & development,

together with the continued support

of a committed workforce and a loyal

customer base has built Blanc de Bierges

into the first choice for many Architects,

Landscape Architects and Designer

specifiers.

Utilising the very latest technology, we

are constantly developing our product

range to provide a broad selection of cast

stone solutions to meet the demands of

the industry.

Hi-tech machinery with computer contolled mixing ensures consistent

product day after day, year after year. But this is only part of the process.

All our moulds are hand made by our team of engineers - dedicated to

producing the very best. In addition, every product is hand finished to

their exacting standards.

Our standard practice is to store all our moulds for 6 months minimum.

Product replacement can be produced to the same specification as the

original with the minimum of fuss.

Reinforced elementsWith the exception of paving slabs, most components exceeding 600mm

in length are normally reinforced. Please ask for verification prior to

ordering. Spiral stairways are classed as structural elements and so

incorporate purpose-made fully welded steel cages fabricated in our

engineering workshop.

Stainless steel reinforcements are also available by special order for all

products intended for permanently wet conditions/areas of high rainfall

and coastal areas.

Quality controlThe material used in every Blanc de Bierges design exceeds the

compressive cube strength requirements of the UKCSA and complies

with all relevant UK and European standards including: BS1217:2008.

Manufacturing capabilitiesStandard products can be modified during manufacture in order to

eliminate costly cutting operations on site. We also offer a service for

the manufacture of special products to clients’ individual designs. Single

products up to 2000kg in weight and 3m in length can be produced in

our factory. We are happy to discuss your requirements.

Production lead timesDue to the scope of our many ranges and the handcrafting of separate

components, all products are made to order. Deliveries of standard

elements are normally made within 4 - 6 weeks with bespoke items

sometimes taking slightly longer.

With over 750,000 pieces produced

each year, Blanc de Bierges is big

enough to cope with even the most

ambitious schemes.

Technical specification

SettsThe range

n 10 standard sizes n 13 fill-in pieces n 4 thicknesses

When specifying, it is important to remember that the dimensions quoted for setts are nominal because they can be laid with or without jointing. Choose between tapered or straight edged setts to suit your application:

u Without joints, they can be laid on their own on a 140 mm module

u With joints, they coordinate with all the products in the range on a 150mm module.

In addition to the two module sizes, there are two series of Blanc de Bierges setts, each with its own dedicated fill-in pieces and bondstones.

Tapered setts

Tapered setts are a traditional form. They are one of the most flexible modules In the range. They can accommodate any curve or contour, Indeed they are the purest expression of the craft, allowing paviors to give full rein to their ability. On the other hand, tapered setts cannot be laid semi-industrially.

Sizes

The nominal dimensions of tapered setts are:

1) 140 x 140 x 40mm 4) 70 x 140 x 40mm

SlabsThe range

n Within the Blanc de Bierges range, there are over 2,000 different formats of slab available based on square, rectangular, round and hexagonal shapes.

Slabs are 50mm or 70mm thick. Slabs bigger than 600mm are reinforced

The craftsmanship of the slabs is perceptible in the surface grain and the slightly irregular shapes; this is what gives them the design flexibility for which Blanc de Bierges is famous. The slabs are particularly suitable for terraces, paths, swimming pool areas and Japanese walkways. The modularity enables them to be laid in a variety of patterns. Slabs for roof gardens are laid either on studs or on a Lite-Ag bed which gives excellent stability.

Sizes - The modular dimensions of some of our most popular slabs are:

StepsThe range

n We can supply more than 80 varieties of step with 4 riser heights (100,150,180 and 200mm)

Sizes are shown as Tread x Width x Riser x Thickness (50mm)

The hand-finished surface is attractive and also provides an effective grip which is particularly important in wet weather. The steps can be laid horizontally, vertically or on edge. to form stairs, low walls, kerbs or cills.When designing an installation of steps, either the straight or the rounded edge can be left visible.

All the Blanc de Bierges components greater than 600mm in length are reinforced and are made by an enhanced process. They are not recommended to be used in combination with standard steps less than 600mm in length. They are usually made to order according to particular specifications. Special small steps with straight or tapered edges can be used in combination with standard steps or slabs. This is particularly useful when forming curved steps, feature surrounds etc.

Sizes - The modular dimensions of some of our most popular steps are:

1) 400 x 600 x 150 x 50mm 5) 300 x 600 x 150 x 50mm

Pool surroundsThe range

n The tiles work perfectly with other Blanc de Bierges products and equally well with wood or any other natural material, including grass. The tiles are laid so that they project a little way over the water and slope down away from the pool. This prevents water splashing out of the pool over the edge. It also prevents rainwater from running in. Any water that does get onto the surround runs off via gutters Into the drainage system.Blanc de Bierges surround tiles have an excellent non-slip surface yet are perfectly comfortable to walk on in bare feet. The edge that faces the pool is usually rounded so that swimmers can get a good grip, but other shapes are available.

The maximum width is 600mm and the normal thickness is 50mm. The most popular widths are 300mm and 400mm. There are tiles with curved edges for diameters from 2000mm to 12m for round pools. There are also inside or outside corner pieces with a curved radius for rectangular pools.

Sizes -The modular dimensions of our most popular surround tiles are:

1) Surround tiles for rectangular pools 400 x 600 x 50mm

2) Inside corners - Outside dimensions 600 x 600 x 50mm Inside dimensions 200 x 200 x 50mm

3) Outside corners - Outside dimensions 400 x 400 x 50mmInside dimensions 400 x 400 x 50mm

L, Saddlebak and U ModulesThe range

n Blanc de Bierges L, Saddlebak and U Modules come in more than 20 different dimensions.

They can be used to construct flower tubs, retaining walls, benches, tiers, steps, balustrades, fountains, table supports and so on. They can be combined with other components in the system to make designs that are both attractive and economical. The L shaped modules are normally hand-finished only on the outer surface but they can be treated on the inside as well. They are usually made without reinforcement, it can be added, but because of their thickness, it has to be in the centre of the material and does not increase the strength by any significant amount. It is important to get professional advice on drainage, particularly when using the modules to make retaining walls, tiers or flower tubs. When they are used to make retaining walls, the height of the earth banked behind the wall should not exceed the height of the wall Itself. Heavy soils should be replaced with lighter garden soil. Planting should be carried out as quickly as possible to prevent the earth from compacting.

Sizes - Modular dimensions of the most popular U- and L modules are:

1) L’3 : 600 x 400 x 600 x 50mm 5) L’1 : 400 x 400 x 400 x 50mm

2) L 3 : 600 x 600 x 600 x 50mm 6) L 1 : 400 x 600 x 400 x 50mm

3) L’2 : 600 x 400 x 400 x 50mm 7) U 1 : 200 x 600 x 400 x 50mm

4) L 2 : 600 x 600 x 400 x 50mm 8) U 2 : 200 x 400 x 600 x 50mm

Copings & KerbsThe range

n There are more than 3000 different accessories smaller than 600mm in the Blanc de Bierges range. They come in three different thicknesses: 50, 80 and 100mm. These include Copings and Kerbs included in this guide.

Both Copings & Kerbs are made with either straight, rounded or chamfered edges. Copings can also be made with drip edges if they are to be used as wall copings. 43 variations are available for any given item.

Specification

To enable you to specify your requirements, we use the following method:

The accessory is viewed end-on and an imaginary cross-section taken parallel to that end. A letter code is used to specify each edge in turn, starting at the bottom left-hand corner of the cross-section and proceeding clockwise, as follows:

A square edge B Bullnose edge C chamfered edge

Where edges also have rainwater drip grooves on the underside (drip edges) the code DE is added.

For example:

kerb with one rounded edge: (asymmetric cross-section) code ABAA

kerb with one chamfered edge: (asymmetric cross-section) code ACAA

(These kerbs must be laid on the AA side)

wall coping with two rounded edges: (symmetrical cross-section) code ABBA

wall coping with two chamfers and two drip edges:

(symmetrical cross-section) code ACCA2DE

Edges can also be dressed on three or four sides to make a pillar coping, for example, the edges of square accessories can be dressed on two adjacent sides.

Special tapered kerbs are also available; these are particularly useful for the edges of lawns since there is no risk of them damaging mower blades

Spiral staircasesThe range

n The Blanc de Bierges spiral staircase is simple and elegant. Its originality is due to the craftsmanship inherent in the manufacturing technique.

The riser and locating ring are an Integral part of the step so the completed staircase forms a coherent, stable and harmonious whole. The solid riser is an important safety factor and it is psychologically reassuring. The non-slip finish characteristic of Blanc de Bierges components is crucial in this type of structure.

All the components are reinforced.

The simple functional design works well with any architectural style, modern or traditional, in historic and listed buildings.

All dimensions quoted are modular and include a 10mm joint.
