Retaining Walls
The embankment to be retained should be graded to
a profile at which it is self supporting. A suitably designed
concrete foundation should be cast in firm ground at a depth
at which frost/heave is unlikely and not less than 10% of
the retained height. The insitu concrete foundation will need
to be designed on a site specific basis having due regard
to the height of the retaining wall and the corresponding
loadings. In most situations, the concrete foundation will
require steel reinforcement.
Ruthin Precast Concrete are pleased to provide foundation
design advice based on specific site data.
Rocwall “L” shaped panels are bedded in 3:1 sand
cement mortar onto the concrete foundation and secured using
the appropriate number of stainless steel resin grouted anchors.
Straight Rocwall panels are normally bedded onto the concrete
foundation with 3:1 sand cement mortar, inclined at an angle
of 6:1 and backfilled with no fines concrete.
Following the construction of the walls, precast or insitu
concrete copings may be provided.
Free Standing Walls
The construction being as above for Rocwall “L”
shaped panels but the foundation design will be simplified
and may not require reinforcement.
Delivery
Rocwall panels may be delivered vertically or horizontally
depending upon their size. Rocwall units should be off loaded
using purpose designed lifting pins and slings and stock piled
on firm level ground in the same orientation as they were
delivered. For details of handling and installation, please
ask for a copy of our Rocwall Installation Guidelines.
Rocwall panels are normally delivered on articulated lorries
in full 25 tonnes loads. Any restrictions concerning the size
of the delivery vehicle should be made known at the time of
placing the order. |
