2. The T-Block Reinforced Wall

3. What is TENAX T-Block System?
The construction of mechanical stabilized wall with a Tenax patented connector between HDPE geogrids and segmental concrete blocks. The connectors are locked into the geogrids which are wedged between two layers of blocks to maintain wall stability.
This mechanical connection allows the system to utilize optimum full long term strength of the geogrids in the design. As the geogrids are interlocked level between blocks, wall rotation would not occur as in some other systems do.

7. The T-Block System Soil - Geogrid – T-clip – Block
T-Clip connector provides effective mechanical connection with the geogrid and the concrete block units to form a totally integrated system

8. Benefits of the T-Block System
Fast and easy to construct
Large cost savings over traditional reinforced concrete structures
Design fully complied to Geoguide 6
No piling and heavy foundation
Possibility of using existing backfill
Area behind wall can be trafficked immediately
Variety of facing aesthetics to suit client needs
Easy conformity to any alignment & profile
Minimize energy, concrete and steel reinforcement
