The T-Block is designed for applications where two walls intersect and is available in two configurations. One model has a short leg (bottom of the T) and one has a long leg allowing the forms to be alternated to ensure that the joints are staggered, increasing the strength of the intersection during the concrete pour and reducing the need for additional bracing. The T-block features a patented 1-inch deep FormLock reversible interlock which connects the forms tightly together without the need for gluing or taping.  It also contains 100 percent recycled polypropylene webs, which hold EPS panels together, hold reinforcing steel and act as furring strips for interior and exterior finishings.
