Cast in situ Linings
The materials used in Cast In-Situ linings are extremely durable in terms of their resistance to both natural weathering and flue conditions.The blend used is tested to B.S. 1902 ASTM standard C401 Class N and has a maximum service temperature of 1200¡ÆC. After thoroughly cleaning the flue a former is inserted and inflated to the correct size.Openings are made in the chimney wall to position the former. The base of the flue is sealed and the blend pumped into the space between the former and the flue wall.Once the blend has set the former is deflated and removed, leaving a smooth internal flue surface. The lining has an expected life span of some 60-70 years. Installation is to the NACE code of practice.The system will make your chimney stronger than new, curing any damage such as joint leakage and general deterioration of the brickwork and will prevent further deterioration.

Stainless Steel Linings
There are two main types of stainless steel lining: flexible and solid, these come in various diameters to meet the customer's requirements. At the time of installation it is recommended that both types are back-filled with a dry insulating material. The advantage of this is not only to reduce condensation but also to reduce thermal shock. Stainless steel linings come with a ten year 'reducing' warrant.
