Designed and developed in New Zealand over 25 years ago, Seismolock offers a practical and economical alternative to traditional strengthening methods.
Many older brick and masonry buildings must now be structurally upgraded or face an early retirement at the hands of the demolition contractors. Other buildings, such as those damaged by earthquakes need to be re-strengthened as part of their reinstatement as safe, habitable buildings for occupants, and equally those in close external proximity should a seismic event occur in the future.
Seismolock has been applied to projects for the New Zealand Fire Service, Otago Boys High (Dunedin), St Josephs College (Invercargill), and Ponsonby Primary School (Auckland) to name a few.
The system, of proprietary polypropylene fibre-reinforced high strength plaster combined with a specially formulated acrylic bonding resin and a high-tensile strength fibreglass reinforcing mesh provides a thin section plaster system that strengthens existing brick and masonry walls to resist earthquake loads.
The Sesimolock GRC re-strengthening plaster is formulated to provide a strong bond to the surface of a masonry wall, while the embedded layers of fibreglass mesh provide the tensile strength to resist in-plane shear loads and face loads on brick and masonry walls. Due to Seismolock’s minimal thickness, loss of floor space is lessened ensuring maximum floor area is maintained.
