PYTHON MT is purpose-engineered for one of the toughest jobs in structural strengthening: creating reliable, seismically rated connections between existing URM masonry and new shotcrete overlays. This ICC-ES evaluated system is designed specifically for shear and tension dowel applications, giving engineers confidence when tying new concrete layers into historic or aging masonry walls. Whether used for seismic retrofits, structural overlays, or heritage restoration, PYTHON MT delivers consistent performance backed by extensive U.S. standard testing, including ICC-ES ESR-5183 for both dry-mix and wet-mix shotcrete applications.
The system offers versatility in the field, with standard lengths of 6 3/8", 9", and 13 1/2", along with custom lengths for unique project demands. PYTHON MT anchors install quickly and provide dependable structural engagement in URM masonry, concrete, gunite, and pneumatically placed concrete. From community buildings to large-scale infrastructure upgrades, PYTHON MT ensures fast, secure, and code-compliant connections that strengthen walls, extend service life, and support safer, more resilient structures.
