Strengthening masonry and concrete in earthquake-prone areas is specifically designed for the Groningen situation and European seismic standards. ANTISEISMIC Grid, ANTISEISMIC Wrap and the related connectors are developed for this.
ANTISEISMIC Grid is a rigid reinforcement mesh specially designed for the CRM (Composite Reinforced Mortar) system: a non-corrosive, high-strength, lightweight, alkali-resistant glass fibre mesh that reinforces existing and new masonry and concrete structures under static and dynamic loads. It increases the strength, stiffness and ductility of structural elements. Ductility is a structure's ability to deform without failing outright, which is essential during an earthquake.
ANTISEISMIC Wrap is a unidirectional carbon fibre fabric specifically designed for FRP systems in seismic strengthening applications. The ANTISEISMIC Connector L-shape and Open End connect the reinforcement to the existing structure, thereby increasing the ductility of the whole.
| Product | Material | Function |
|---|---|---|
| ANTISEISMIC Grid | Alkali-resistant glass fibre | CRM system, masonry and concrete reinforcement |
| ANTISEISMIC Wrap | Carbon | FRP system, unidirectional fabric |
| ANTISEISMIC Connector L-shape / Open End | Carbon, AR glass or basalt | Connection and increased ductility |
In the CRM system, ANTISEISMIC Grid is applied in a layer of mortar on the existing wall; ANTISEISMIC Wrap is applied with resin around or on the structural element. The connectors are drilled through the structure and anchored. The exact execution is given in the technical data sheet per product and, given the seismic function, always requires a project-specific design.
The products are designed for European seismic standards and the specific situation in Groningen. The exact application limits and design values are given on the technical data sheet; the seismic sizing is done per project by a structural engineer.
The products are specifically designed for the Groningen situation and European seismic standards; the concrete approach and sizing for a specific home is done per project by a structural engineer.
CRM stands for Composite Reinforced Mortar: ANTISEISMIC Grid is applied in a layer of mortar on the existing wall to increase strength, stiffness and ductility.
Ductility is a structure's ability to deform without failing outright. During an earthquake, sufficient ductility prevents a sudden, brittle collapse.
