The T-Block Reinforced Wall
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.

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

Some Examples – Major Roads
South, Korea – Chunsugyo-Saebeari
Highway: Segmental Retaining Wall System
Dubai – design for the landscaping
structures on major road projects
Some Examples - Walls
Ireland – The T-Block System optimizes
the cost and space availability within site
boundary constraints
Seoul, Korea – This wall shows the flexibility
of the T-Block System that maximizes the
use of a small, busy urban area, and yet,
with ample parking facilities and
aesthetically pleasing recreational areas
