|  The
Rocwall system comprises standard panels of steel
reinforced precast concrete with one side faced with natural
stone and the other with concrete which can, for free standing
walls, be provided with an exposed aggregate or textured finish.
Parapet units designed to compliment the standard panels
are manufactured from the same materials with natural stone
applied to both faces. Matching coping units can also be provided.
Each unit is tongued and grooved to ensure positive location
with adjoining units. A strong durable construction is achieved
without the need for steel straps or bonding compounds between
units.
It should be noted that the joints between panels are not
designed specifically to provide for the drainage of water
as this is more effectively dealt with by the provision of
a land drain at the rear of the wall and backfilling retaining
walls with free draining stone. Where specifically required,
Rocwall panels can be provided with a uPVC
lined weep holes.
 Rocwall
retaining wall units are designed in accordance with BS 8002
– code of practice for earth retaining structures. Standard
units are designed to retain material with an assumed unit
weight up to 18kN/m3 with an internal angle of friction of
>350 with retained material level with or below the top
of the wall units.
The units are designed to withstand a superimposed load of
10kN/m2 or a retained material surchage angle of up to 300
from the horizontal.
Ruthin Precast Concrete’s experience and knowledge
of retaining wall systems is applied to a free advisory service
to Rocwall customers. Analysing customer
requirements and site conditions, we are able to provide detailed
proposals for Rocwall construction on a site
specific basis.
