Stresses
and scarring
protection
SYNTHO-SLEEVE™ is designed to
protect welded field joints on pipelines
from the abrasion stresses and scarring
of directional drilling and boring. Syntho-
Sleeve provides mechanical protection to
the preapproved corrosion coating of your
choice, such as viscous elastic coatings,
epoxy coatings, shrink sleeves, and
cold applied tapes. This unique product
has a faster setting time, is easier to
apply, has a very low profile, is extremely
conformable, and is impact resistant.
The result is cost-effective, long-term
protection against corrosion for buried
pipelines.
Typical applications for this product are
horizontal directional drilling, boring, coating
repairs, and coating protection.

Hobas wins
ISTT No-Dig
Award
AFTER receiving the national No Dig
Award from the Polish Society for
Trenchless Technology (PSTT) in 2010,
Hobas has now won the internationally
renowned ISTT (International Society for
Trenchless Technology) No-Dig Award
together with the construction company
group PBG.
3m large Hobas CC-GRP jacking pipes
were utilised for the trenchless installation
of an intercepting sewer leading to the
wastewater plant ‘Czajka’ in Warsaw. The
pipes’ XXL diameter and the length of
microtunnelled line were not the project’s
only impressive features. Thanks to the
properties of the pipe material, national as
well as international records were broken
regarding the single drive lengths from
one pit up to 930m, the peak installation
speed of 36m per day and the small
number of drives on the 5.7km partly
curved lengths.
Implemented by assignment of the
MPWiK Warsaw (City Waterworks) and
supported by the EU Cohesion Fund, the
job is part of the largest environmental
EU project, ‘Water Supply and Sewage
Treatment for Warsaw’. Microtunnelling
5.7km of 3,000mm diameter Hobas
CC-GRP pipes with state-of-the-art
trenchless technology led to the shortest
possible installation time and kept impact on
the environment and city-life to a minimum.
With the combination of installation method
and chosen pipe material the PBG Group
executed an economically and ecologically
beneficial solution, while providing long
service life.
The project drew more than 500
international visitors including the GSTT
convention to the site in Warsaw during
the 13 months of installation works, and
convinced the ISTT jury of the technological
importance this successfully implemented
project presents.
