Thermocrete Chimney Relining



Cast in place chimney liners (a.k.a. poured in place or pumped masonry liners) are made from a volcanic rock which makes the liner fireproof. Within the rocks are also thousands of microscopic air pockets which makes it very light weight with an excellent thermally insulated quality. A cast in place liner is a highly insulated, one piece masonry, continuously pumped-in chimney lining system that is used in lining new and old chimneys of any type. Cast in place liners are used for residential, commercial or industrial applications.  Cast in place lining can be used for any type of installation, for example; fireplace, furnace, boiler, incinerator, wood-stove, pellet-stove or corn-stove. Cast in place lining can also be used with any fuel type; natural gas, home heating oil, wood, coal, corn and pellet. Cast in place lining is well know to be the best method for historic fireplace restoration and lining for un-lined Chimneys.

The Pumped Chimney Relining System is perfect for chimneys that were never lined with clay pots/liners.
The chimney relining material is pumped around a special former which runs the length of the flue. The thermocrete then fills all voids, cracks and defects in the chimney.
The chimney is filled to the top and left to cure.  When the former is removed the customer is left with a new seamless flue which has enhanced the structural integrity of the chimney stack and is heat resistant above 13oo°C.

Clay liners can withstand temperatures of 1000°C – CHIMNEY FIRES can reach temperatures of 1200°C


Other benefits include a more efficient flue which is easier to maintain.

15 Reasons Why Cast in Place Lining is the best type of Chimney Liner


1. Zero-clearance to combustibles with only one inch of lining material.

 2. UL Listed by Underwriters Laboratories.

 3. Withstands flue fires over 1300 degrees C.

 4. Seals any voids or missing bricks and cracks in brickwork also any loose masonry will be unable to fall as it will become bonded together as one continuous piece from bottom to top.

 5. Fills damaged and recessed mortar joints.

 6. Seals interior chimney walls, preventing smoke and poisonous flue gases such as carbon monoxide and sulfur dioxide from escaping into the home.

 7. Any deterioration in a chimney will stop completely and be filled in structurally.

 8. Highly insulates the chimney which increases stack temperatures thereby reducing condensation from high efficiency furnaces or creosote formation in wood burning.

 9. It will provide a constant flue gas temperature in the chimney in return providing a constant natural draft of the chimney system which will allow appliances to operate at their highest possible efficiency.

 10. It will eliminate excess heat transfer through the chimneys masonry surrounding work which is the most common cause of structural fires from a chimney.

 11. Adds structural strength beyond original construction.

 12. Impervious to the attack of acids produced by gas and oil furnaces.

 13. Allows chimneys with multiple offsets to be lined.

 14. The smoke chamber is lined, protecting the heart of the chimney.

 15. Cast in place lining results in a one-piece masonry liner and smoke chamber with no seams to leak or joints to weaken later.
