A comprehensive range of one-piece moulded Manhole
Chamber sections for use by the Utility Companies and Building
Our range of manhole chambers are made from 100% recycled plastic
material normally destined for landfill and share the multiple
benefits common to all of the products in our Enviro-Range.
Using Envirochambers can help meet the demands of Health and
Safety Requirements, Project Efficiency and Component Quality and
is the ideal solution for manhole chambers and composite manhole
covers for Fire Hydrants, SV Valves and Sewage / foul water
Advantages when using Envirochamber products over
Lighter, Stronger, Safer, Easier to handle and to Install, Little
or No Breakages through transportation or installation and
Environmentally Greener than traditional materials.
Envirochamber manhole sections are made so that the unit weight is
far less than those made from traditional materials such as
concrete and will normally fall within the H&S guidelines for a
one man installation.
This reduces the installation time and cost and can help meet the
Health and Safety requirements on RSI.
Innovative design and faster installation
The internal clear openings for the standard range of chamber
sections come in sizes common across the Water and Building
Industries and are available in a range of depths some of which are
not available on chambers made in traditional materials such as
concrete due to weight or manufacturing constraints. The chamber
sections for all sizes have a built in interlocking system that
gives a secure and robust assembly.
The sections taper from the top face to the base to assist sealing
of the completed chamber. Also due to the interlocking system and
the light weight the Envirochamber design sections can be assembled
quickly and accurately. Silicon Sealant can also be applied between
the sections to stop the ingress of contaminated water into the
finished chamber.In the case of the Hydrant and SV ranges separate
base units are available and can be supplied either as a one piece
unit or a two piece unit for retro fitting around pre-installed
pipes or valves.
These base sections have raised pieces to locate securely into the
under side of the chamber sections to hold the chambers securely
whilst they are being assembled around the valve or pipe work and
to restrict any movement of the assembly due to backfilling or
concreting when finishing the chamber.All chamber sections, Hydrant
- SV and Large, have a purpose made built in location system on the
top section to positively locate the Cast Iron Cover and to stop it
sliding or moving when the contractors finish the chamber. The
Hydrant chamber section can be used to repair existing damaged
concrete chambers with special component parts required. As well as
the Locating ribs the range of Larger Envirochambers have purpose
made hand holds to assist in the manhandling from the pallet or
transport and to speed up the installation of the chamber.
This range of large chamber is available in three internal opening
sizes and in all cases two depths.
Specialised Product Range
The Enviro Range includes Fire Hydrant Chambers Sections and SV
chambers with a range of compatible bases.
PDS manufacture a Closing System with a Base, Shaft Pipe and Top
Hat profile, which allows a chamber to be closed below ground level
(Kettler Spindles) but allows access from the surface in case of
SV chambers and their bases are available as an alternative to
heavy concrete sections in the installation of Sluice / Stop
PDS have manufactured a range of units to meet the market need for
Larger Chamber Sections and offer a size range from 600 mm x 450 mm
thro to 900 mm x 600 mm clear openings. All are made with purpose
made hand holds and built in location system. A further benefit
built into the design of the larger chambers is a wider shoulder
bearing area which provides full support for the new design of
manhole covers such as the Opt-Emax or similar which have large
flange areas at the corners.
The Envirochamber manhole sections are made entirely from recycled
materials that would have ended up in landfill site within the UK
or overseas this has helped to reduce the carbon footprint of not
only PDS but also the producer of the waste plastic, transport
companies and you the final user of Envirochambers.
Traditional manhole chamber sections manufactured in materials
such as concrete rely heavily on fossil fuels to make the raw
materials this give s high carbon footprint.
The lighter Envirochamber reduces the amount of transport required
to move the same number of products in concrete (more on a wagon)
from the manufacturing site to the customer.
At the end of the Envirochambers useful life unlike products made
from traditional materials they can be recycled and the material
reused no matter how long its been in use above or below
Envirochambers are all tested and certified in an unsupported
state to BS 5834-4 1989 and to EN 124 D400 loading.
