Fabriform Concrete Bags are large cast-in-place concrete
bags, similar to the Storm Mats. The Concrete Bag sizes vary and
are fabricated specifically for each project. They are traditionally
used to protect against scour at bridge piers and wing walls.
Storm Mat
Developed to protect against typhoons in S.E. Asia,
Storm Mats are employed in lieu of armor stones. They vary in size
and are very similar to Concrete Bags. The Storm Mat has more of
a true “block” shape, verses the tubular shape of the
Concrete Bag. The most common is the 16” (thick) Storm Mat.
Storm Mats can be installed individually or the blocks can be assembled
into monolithic mats.
Storm Mats are used where severe scouring may occur
or where increased toe protection is needed. Due to their block
shape, the Storm Mats resist rolling better than Grout Bags and
can be easily stacked on one another.
Some areas of installation for Storm Mats & Concrete
Bags are: toe protections along rivers and bridge piers, protection
at cruise terminals, sub-aqueous pipeline outfalls, groins and breakwaters.
Storm Mats and Concrete Bags provide superior
scour protection with significantly reduced labor and equipment
requirements.
