SAN DIEGO MASONRY CONTRACTORS | PROTO II WALL SYSTEM

TIDWELL MASONRY has the required certification to build with the Proto-II™ Wall System. If you want a block wall built, this type of wall should be taken into consideration. The Proto-II™ Wall System is designed to save you money! There is a total of up to 40% savings in choosing to have a Proto-II™ wall built instead of the conventional type. With over 25 years and over 20 thousand miles of the Proto-II™ walls being built in Los Angeles and Riverside County, it has proven itself as a reliable engineered system. Now, the PROTO-II™ POST TENSION MASONRY WALL is an excellent choice for SAN DIEGO! The Proto-II™ type wall can be built using any type of block, such as the Split-face, Slump or Standard units. These walls can have a stucco or plastered finish and can be veneered.

The Proto-II™ Wall System is a patented and engineered masonry wall design that uses post tensioning to structurally support masonry in lieu of rebar and grout. The Proto-II™ Fence and Retaining Walls use the same masonry block and have the same appearance as conventional masonry walls. The difference is on the inside: Conventional masonry walls use rebar and grout for support, while the Proto-II™ Walls use post tensioning. This advanced technology provides a stronger, more efficient design. The Proto-II™ Wall is available in 4”, 6” and 8” wide masonry fencing and also in 8” and 12” wide retaining walls.The Proto-II™ Fence Wall is stronger and more durable than conventional or segmental masonry systems and a far superior product than vinyl or wood fencing. The post tension design is a blend of efficiency and strength resulting in a superior, cost saving product. Proto-II™ Fence walls can be built in lieu of competing conventional masonry walls, vinyl fencing or wood fencing. With the Proto-II™ Fence Wall System, significant savings and superior structural integrity are realized without any compromise in appearance.

The Proto-II™ Wall is constructed using concrete footings and standard concrete masonry units (CMU block). High strength steel tension rods are connected to rebar in the footing. A Steel bearing plate, a high grade nut and a Direct Tension indicator (DTI) washer are installed near the top of wall. The rod, plate and nut assembly are tightened to a specific torque rating which collapses the DTI to achieve the specified tension within a 3% tolerance. The tensioning results in compression distributed throughout the wall, dramatically increasing its strength and load capacity over conventional grouted masonry walls.
