Wavin Plastics - New OSMA Tegra 600 non entry inspection chamber
gets seal of approval
Wavin Plastics’ innovative OSMA Tegra 600 non-entry inspection
chamber has passed rigorous industry tests to achieve a certificate
of approval from the BBA (British Board of Agrément).
Designed to provide easy installation, inspection and maintenance to
non-adoptable domestic and commercial drainage systems, the chamber
successfully passed a range of technical investigations to receive
the industry accolade.
Spokesperson for Wavin Plastics, Michelle Fleming, said she is
delighted with the recognition.
“We were always confident that Tegra 600 would make a real impact,
but to achieve BBA approval with the new product is great. It is a
credit to the engineers and designers who worked behind the scenes,”
she said.
Tegra 600 is constructed from strong polypropylene and is much
lighter and easier to handle than large concrete manholes. The
chamber can be installed by hand and backfilled in a day, three
times faster than its rival. There is also less of a health and
safety risk with Tegra 600 which can be used to examine buried
pipework up to 5 metres deep.
“It is an extremely safe and easy-to-use inspection chamber that
significantly reduces the installation costs associated with routine
pipe maintenance. Using the Tegra 600 means far less risk to
personnel, both during installation and service.”
During its assessment by a BBA panel of experts the chamber was
subjected to a number of tests where its mechanical properties came
under close scrutiny. It was found that the chamber has adequate
stiffness for depth of burial and is not directly affected by wheel
load from traffic.
Other tests successfully carried out on OSMA Tegra 600 were done to
determine water tightness, strength of joints, a resistance to
negative pressure, dimensional accuracy and impact resistance. The
results concluded that:
● Joints between the chamber and pipeline remain watertight under
conditions where pipeline movement is in excess of those expected to
occur in normal good drainage practice
● The chamber to the shaft connection does not allow seepage of
water
●The chamber has satisfactory flow characteristics to prevent
blockage
A further evaluation of the chamber was made to assess its
structural integrity, durability, practicability of installation and
ease of maintenance from ground level. All were successfully
negotiated.
