The Articulating Block style is a form
for casting in place heavy-duty, rectangular concrete blocks in
a staggered joint pattern. The 6" AB style comes in staggered
and a non-staggered configuration. This revetment style can be reinforced
by inserting nylon cables between the two layers of fabric. The
imbedded cables allow the cast-in-place concrete blocks to flex
(articulate) with changing soil and water conditions.
4" Articulating Block
The smallest in the AB style, the 4"AB,
is used where soil consolidation or changing water conditions may
occur.
6" Articulating Block &
6" AB non-staggered
The most common AB style, the 6"AB,
is used where soil consolidation or changing water conditions may
occur and added weight is advised. The larger size gives greater
scour protection. The 6"AB mat also comes in a non-staggered
configuration.
8"
Articulating Block
The largest in the AB style, the 8"AB,
gives the greatest protection from scouring, changing soil and water
conditions and abusive wave action.
Some areas of installation are: drainage
ditches, bridge piers & abutments, water control structures
& dams, Intra-coastal waterways & shoreline protections,
turning basins in ports & marinas, boat ramps, sub-aqueous pipelines,
landfill covers, dikes & levees, and other areas that are susceptible
to more severe wave action or increased flow velocity.
