Castable & Guniting

Castable and gunned refractory linings are used to protect high-temperature industrial equipment such as furnaces, kilns, boilers, and incinerators from heat, abrasion, and chemical attack.

These systems provide a durable and adaptable alternative to traditional brickwork linings, particularly in applications where complex geometries, reduced installation time, or flexible repair solutions are required.

Castable refractory is typically mixed and poured or cast into formwork to create a dense, uniform lining with controlled thickness.

Gunned refractory, by contrast, is applied pneumatically using compressed air, allowing the material to be sprayed directly onto surfaces. This makes it particularly effective for vertical, overhead, or irregular surfaces where traditional casting methods may be less practical.

These systems are widely used in high-temperature process environments such as furnaces, boilers, incinerators, petrochemical units, and power generation equipment.

They are suitable for both new installations and maintenance works, particularly where access is restricted or rapid installation is required.

Castable and gunned systems offer reduced jointing compared to brickwork, resulting in improved structural integrity and resistance to gas or heat penetration.

They also provide strong bonding to substrates and flexibility in application. Gunning, in particular, enables faster installation and is well suited to complex geometries or difficult-to-access areas, helping to reduce downtime during installation or repair.

Yes – both systems are commonly used for repair and maintenance work, especially during planned shutdowns.

Gunning is particularly effective for patch repairs, localised relining, and areas where speed and accessibility are critical, allowing Ancorite to restore lining performance efficiently while minimising disruption to operations.
