             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.

                 Building
                  on success




                                                      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.

                                         Saddlebaks and U shaped modules
                                         are   particularly       useful   in   the
                                         construction of larger stepped areas and
                                         Amphitheatres.

                                         Their intrinsic uniformity providing a
                                         warm harmony to changes in ground
                                         level within a scheme.

                                         Special adaptations can be specified to
                                         include lighting primarily as an aid to
                                         safety but also adding a unique ambience
                                         to the stepped area of an Amphitheatre.

            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 steps
            Formed 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.

Radial steps
Radial 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.

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 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.
