THEY PUT OUR LINER TO THE TEST! |

 |
|
ASSEMBLY DIAGRAM |
The test was to simulate field performance of the
installed CIPMH™ Chimney Liner when exposed to repeated freeze/thaw
cycles. A manhole chimney was constructed using un-mortared bricks and
an unsealed concrete adjustment ring. The ground was simulated by
setting a 4-foot diameter tank on the outside of the chimney and then
backfilled with crushed limestone.

LINER INSTALLATION |
A CIPMH™ Chimney Liner was installed in the chimney
and overlapped onto the corbel. The tank around the chimney containing
the crushed limestone was filled with water, therefore, simulating
saturated ground conditions. The un-mortared brick allowed the water
to be in direct contact with the backside of the liner. |
FLOODED BACKFILL |

ASSEMBLY FREEZER |
The independent engineering firm of Allgeier,
Martin and Associates, Inc. placed the entire assembly into a walk-in
freezer at negative 18°F for a 4 days.
The entire assembly was frozen including the water, liner, backfill,
corbel, and chimney. The assembly was then removed from the freezer
and allowed to thaw. The process was repeated. |
ICE IN FROZEN BACKFILL |

|
Allgeier, Martin and Associates, Inc. of Joplin,
Missouri inspected the liner and found no change in appearance or
condition. The liner was tightly adhered to the manhole frame,
chimney, and corbel. No evidence of leakage throughout the chimney was
observed during or at the conclusion of the test.
The CIPMH™ Chimney withstood one of the most
powerful forces of nature, it will definitely solve YOUR
chimney problems.
