Denlok
technology
reduces
disruption
DENLOK, manufactured by Yorkshire based
drainage solutions company Naylor, is
available from 150mm to 700mm diameter
and has been widely used to minimise the
impact of civil engineering works in our
streets and cities.
Production and installation of Denlok also
has an exceptionally low carbon footprint
– clay is a naturally occurring material, is
in abundant supply, and has low embodied
energy and unrivalled longevity.
In contrast to open cut installation the
environmentally beneficially, trenchless
technology is characterised by minimal
surface disruption over a much shorter
period of time, less soil going to landfill,
and less newly quarried materials being
needed for backfill. On a well-managed
trenchless project, the public will not be
aware that major construction work is
actually going on below them.
Trenchless technology is no longer the
preserve of the specialist with expensive
kit and a high degree of expertise. It offers
a lower cost alternative to open cut pipe
laying; it will save the costs of lane rentals,
road closures, reinstatements, landfill and
aggregate tax.
The tunnelling equipment has become
less expensive and easier to use. When
pipes need to be installed under waterways,
railways and heavily trafficked areas or in
groundconditionswhere it is simply toodifficult
for trenches to be economically constructed
and worked, trenchless installation is the only
sensible approach.
