THE PUMPED SYSTEM
How the Thermocrete chimney
lining system works.
The basic concept of the system is simple but extremely effective. A rubber former is inserted precisely in position through the entire length of the flue .Special techniques are used to keep the former centralised, even if the flue has a 45° bend. Thermocrete B2c material is pumped into the flue from the top of the chimney stack filling all voids, cracks and damaged joints. When the Thermocrete has hardened, the former is deflated and removed leaving a perfectly smooth cylindrical flue.
Industrial Applications – – – Industrial flues serving boilers up to 1.5 million BTU have been lined with Thermocrete. The principal is exactly the same with the pouring process being repeated in stages until the full height of the chimney is reached.
