BPC Building Products has launched PowaTwist, a permanent crack repair system for masonry.
PowaTwist from BPC Building Products is a fast, non-disruptive repair method for stabilised masonry that is designed to eliminate the need to rebuild and minimises the likelihood of further cracking.
The PowaTwist system consists of stainless steel PowaTwist Bars and PowaTwist Grout. In combination they are designed to provide axial strength and bonding characteristics when reconnecting cracked masonry.
Cracks in masonry can occur in new and older buildings due to a variety of reasons including ground settlement, temperature fluctuations, damp, wind loadings plus many others.
The stainless steel helical-design of the PowaTwist Bars provide greater effectiveness in tackling these cracks, when used with PowaTwist Grout, because it distributes the load over the entire length of the PowaTwist bar. This ensures no load and tension concentration.
Manufactured from stainless steel, the system is suitable for aggressive environments and no additional plates, screws and fixings are required.
PowaTwist Grout is suitable for injection with an applicator gun and is especially formulated for use with PowaTwist bars. The Grout completely fills all voids and develops its compressive strength rapidly.
The PowaTwist bar is available in 6mm diameter x 1000mm lengths as standard, or 1.5m and 3m lengths to order, in 4.5mm, 6mm, 8mm or 10mm diameter. The grout is available in individual 3 litre tubs.
Alternatively, the PowaTwist systems is available as a kit (10no. 6mm x 1000mm bars, 1no. 3 litre tub of grout, gun, stainless steel nozzle, mixing paddle, finger trowel).
