Polimask
THE SAFEST AND MOST EFFICIENT SYSTEM FOR CREATING DUCT BANKS
DOCUMENTS AND RESOURCES
Duct banks are systems made up of pipe bundles, usually plastic and buried, through which various types of cables (fibre optics, power lines, telecommunications, etc.) are fed. Depending on the number of pipes and the distance to be covered, duct banks can be very large, with inspection chambers located several kilometres apart.
These systems serve to protect the cables inside them against mechanical stresses and moisture, thus preventing potential oxidation damage. However, in traditional installations it is difficult to ensure a watertight seal between the duct bank and the inspection chamber, which can lead to water seepage and, in the most severe cases, the flooding of the chambers themselves. In such situations, the only solution is to pump out the water, which can be extremely expensive. Designed in using PPEcoforte pipes, generally 110 mm in diameter, the Polimask system was developed to solve this problem.
STRENGTHS
OF THE POLIMASK SYSTEM
INSTALLATION SPEED
The positioning and alignment of the pipes, the water tightness check, and the assembly of all the components are carried out in a single step.
MULTIPLE UNIT INSTALLATION
Multiple Polimask units can be easily combined to create large inspection chambers.
WATER TIGHTNESS
Water tightness is guaranteed by the water-stop seal, made from water-expanding material.
FLEXIBILITY
The Polimask system is suitable for wall thicknesses of 150 to 370 mm.
PROTECTIVE CAPS
The built-in caps ensure cleanliness and absence of debris in the pipe connection areas.
DOUBLE SEALING
Double o-ring stub pipes ensure a double seal between the mask and the piping.
INSTALLATION STEPS
The steps for installing the Polimask system are extremely simple:
Laying and fitting the pipes
The Polimask system includes a bracket for positioning and aligning the pipes with maximum precision: it is designed to ensure the correct distribution of the concrete and the elimination of air using a vibrator, and is equipped with connectors and support bases that allow for multiple brackets to be connected, in order to create large duct banks.
