We offer full roadway evaluation, design and contract installation of explosion rated seals. Our installed structures are fully rated and quality control tested to ensure construction is completed according to full design specifications. Contract installed structures are fully rated and quality control tested to ensure construction is completed according to full design specifications.
Rating achieved immediately
Superior cloth strength
Lightweight mesh stopping used to replace the use of steel reinforcing mesh sheets that are typically used for low cost ventilation structures. Fleximesh, a high strength webbing, can be attached to the periphery of a mine opening using eye bolts and knocker line. Once in place the lightweight vent bag fabric is attached to form a rapid and low cost ventilation barrier. Fleximesh is safer, lighter and faster to use than steel mesh. Due to its high strength it is also reusable. Download Fleximesh Technical Data Sheet
Explosion rated Flexi-stop, a patented flexible stopping system, can be rapidly installed in high ventilation areas. The flexible structure and sealing system allows stopping to take significant convergence without affecting stopping integrity. Explosion rating is achieved immediately on completion of installation, generating no dust or fumes during installation process. Superior cloth strength ensures resilience to projectile damage. If required, the unique fixing system allows easy detachment for vehicle access. Rated man-door designs can be provided to suit customer requirements.
Devices include various sprayed structures using Minova’s Sprayplast, Rappass GD, or Tekflex® products. Explosion rated Sprayplast structures have been tested to withstand blast pressures of 20 and 50 psi. Download Flexi-Stop Technical Data Sheet
