In recent years, the increasing number
of failed duct sealing events has drawn attention to selecting a
better system suited to the site conditions and requirements. This
action has led many companies/people in search of new options that
have a lower price point and are faster than traditional solutions.
As a result, the need for an affordable, quick & effective solution
is becoming the norm which is why our NEW
MD5 duct sealing system has been created to bridge the gap
between DIY foams and the more expensive systems. |
It is critical to evaluate the
specific duct sealing situation and identify the objectives of the
seal. For Example:
- Are there cables in the duct, how many?
- Does water need to be blocked? How much water?
- Is a fire stop needed?
- Does the conduit enter a building?
- Are gases or chemicals a concern?
Selection should be at the design stage where the seal requirements
can be matched to the overall project. Typically, a design
specification will require water, gas and perhaps fire-resistance
together with specific chemical resistance. The life of seal needed
should also be considered. Every seal manufacturer should be able to
provide proof of expected life. Over-engineering the seal design
should also be avoided. A duct sealing
solution that meets the specific needs of the application is the
right solution.

Training and preparation -
First read and following the manufacturer�s instructions. Like any
other job a field mechanic performs, it requires knowledge and
skill. Duct sealing solutions should be engineered into the job and
training completed in advance of the field work.
Sealing system selection - Most underground duct sealing
systems will need to block water, gases and be tolerant of
hydrocarbons. If the duct enters a building, a fire stop may be
required. Select a sealing system that addresses the risks present.
Cable separation - This is the area where most duct seals
will fail; either the product doesn't support cable separation, or
the installer has been unable to separate the cables sufficiently.
Without separation, water and gases will simply wick through areas
without the sealant.
Conduit Sealing
-
Our range of conduit sealing systems have been designed to provide a
simple and effective solution for watertight and gas sealing of
pipes and cables in conduits, boreholes and ducts. Conduit sealing
systems can be installed horizontally and vertically, they are
extremely flexible. |
