The Helibeam System uses pairs of long HeliBars bonded into mortar to form deep masonry beams that reinforce and stabilise existing masonry while redistributing the structural loads.
It provides a rapid, cost-effective means of restoring structural integrity to buildings and structures where the masonry has failed and lost its load bearing capabilities. In combination with other Helifix ties and fixings it provides a comprehensive, reliable and economic system of repair and stabilisation for many commonly occuring structural faults.
Where masonry has cracked and failed, as a result of ground movement, component failure, weathering or increased loads and stresses, the Helibeam System comprises the installation of horizontal bed-joint reinforcement by tying the masonry together and creating deep masonry beams which distribute the structural loads. Other ties and fixings provide appropriate lateral and vertical restraint to complete the System which has been proven in all types of masonry structures.
Subsidence Superstructure Repairs
For most situations the Helibeam System is able to secure the building by creating masonry beams that reinforce the existing masonry and redistribute the loads away from the problem area. Combined with tying, pinning and crack stitching, the Helibeam System will restore full structural integrity. Subsidence: Substructure repairs In some cases, use of the Helibeam System in conjunction with concrete pads under the building corners, or at selected points, minimises the need for expensive and extremely disruptive mass underpinning.
Failed lintels/window replacement programmes
If lintels have lost their load bearing capabilities the traditional solution is to cut out the brickwork, mechanically support the masonry above and install a new concrete lintel – all very disruptive, time consuming and expensive. The Helibeam System utilises the existing masonry to create a masonry beam above the window to provide the required structural support, often in conjunction with vertical pinning using DryFix or CemTies. For window replacement programmes where the window frame has been used to support the masonry, the Helibeam System provides a rapid and economical means of creating a lintel within the existing masonry.
Bowed and separated walls
Where internal and party walls have seperated from the external elevation, and depending on the individual situation, the Helibeam System gives horizontal restraint in the external wall while BowTies provide lateral restraint and grouted CemTies are used to reconnect the internal and external walls. Cracked masonry Depending on the cause of the cracking, HeliBars are grouted into channelled-out slots (normally the mortar beds) across the crack to provide simple, permanent and non-disruptive stabilisation of the masonry.
