Thor Heliforce Bars forming lintels and over-pinning video from
Thor Helical

Thor Heliforce bars are used for forming lintels over window openings or for over-pinning areas of ground movement such as subsidence or heave. The mortar joint reinforcing bars extend 500mm either side of the opening to ensure sufficient dead weight fixity to limit deflection of the lintel under load conditions. Heliforce bars are available solely from Wykamol Structural / Thor Remedial.
