“We have vast experience of working in a
range of poor ground from soft clays, silty
alluvials and contaminated made ground.
Through working with Cenin and their state
of the art laboratory facilities, we have the
ability to provide engineered solutions for
the most complex environmental or geotechnical problems,” says Paul.
Typical end uses for re-engineered material
include CBR Bulk Fill, CBR Capping replacement, and CBR Sub-base replacement. These
products have the potential for use in addition
to typical earthworks and pavement construction in areas such as drying stockpiles to make
them suitable for screening. They can also be
used for piling mats, crane pads, temporary
access tracks and winter working platforms.
With the ability to work as a main contractor and carry out enabling works on a new site
including demolition, earthworks and civils, as a
subcontractor carrying out ground engineering
works on an existing site or even supplying
complete turnkey treatment solutions, DLS can
be relied upon to provide the answer to clients’
ground engineering problems.
The company has also begun to work with-

in the emerging energy sector with the likes
of G2 and Lightsource. For example, G2
Energy was contracted by its client, a wind
farm developer, to provide EPC services on a
handful of 500kW single wind turbine projects within the same locality in Yorkshire. The
project involved upgrading existing access,
installing new access, foundation works, substation construction and new HV cabling to
the point of connection.
G2 Energy approached DLS to carry out
enabling works comprising the construction
of the access roads and crane pads to four
sites, which the company carried out using
soil stabilisation.
The subgrade material along the route of
the new road and crane pad was stabilised using
an ultra low carbon binder from Cenin Cement
and a layer of Type 1 was pushed out to act as
the running surface. This Type 1 layer was then
mixed with cement to provide the strength
characteristics required by the cranes during
the turbine erection works.
“Using soil stabilisation on this project
enabled G2 to re-engineer the existing material
on site to provide an enhanced strength to the

road and crane pad through stabilisation,”
remarks Paul. “This meant that the amount of
aggregate required to be brought in to site was
significantly reduced, along with all associated
vehicle movements.
“The vast in house plant and labour
resource of DLS along with our own transport
services enable us to operate nationally and
means that we can react to our clients’ needs
very quickly.”
