Following extensive research at the TRL, Helifix have developed a range of innovative solutions for the maintenance and strengthening of brick and stone masonry bridges, viaducts and tunnels.
Aesthetic repairs secure cracked masonry arch
With the fully concealed repair completed, structural integrity was restored to the arch with its visual appearance unaffected.
Strengthened bridge meets EU load standards
The weak Smithy Bridge was sympathetically and economically strengthened using Helifix fixings to accept full highway loadings and comply with EU regulation.
Historic Lymm Bridge Stabilised
The historic Lymm bridge was fully stablised and strengthened by Helifix with no visible signs of the concealed non-disruptive repairs.
Ancient monument stone bridge restored
A bridge built in 1792 was fully restored with concealed repairs, visually unaltered, and approved by Gloucestershire Highways and English Heritage.
Weak Grade II listed stone bridge repaired
A bridge over a river in Somerset had become weakened. Helifix repair techniques were used to quickly and cost-effectively restore the heritage structure.
Natural stone bridge repaired
This natural stone bridge carries a road over the Dulais waterway. Helifix concealed repairs and strengthening left the bridge visually unaltered.
Bridge strengthening increases load capacity
The concealed repairs and strengthening enabled the weight restriction to be increased, from 7.5 tonnes to a 40 tonne load carrying capacity.
Canal bridge repaired and strengthened
A burst water main caused movement of the spandrel and parapet walls together with separation between the arch barrel and the voussoirs, requiring repairs.
Grade II listed railway viaduct
Due to long-term effects of normal wear and tear, compounded by a shallow depth of fill above, this seven span viaduct was showing a variety of structural faults.
