Specifications include, but are not limited to: Cellular concrete mats will be assembled by the
owner upon delivery.
Individual units in the system shall be capable of
being staggered and interlocked for enhanced
stability. The mats shall be constructed of open cell
units and half solid blocks. The open cell units shall
have two (2) vertical openings of rectangular cross
section with sufficient wall thickness to resist
breakage during shipping and installation. Parallel
strands of cable shall be capable of being extended
through two (2) cable ducts in each block allowing
for longitudinal binding of the units within a mat.
Each row of units shall be laterally offset by one-half
of a block width from the adjacent row so that any
given block is cabled to four other blocks (two in the
row above and two in the row below).
Each block shall incorporate interlocking surfaces
that minimize lateral displacement of the blocks
within the mats when they are lifted by the
longitudinal revetment cables. The interlocking
surfaces must not protrude beyond the perimeter of
the blocks to such an extent that they reduce the
flexibility or articulation capability of the cellular
The concrete units shall be produced by a dry cast
method. The dry cast units obtain strength in a
shorter duration as well as an increase in the
durability and overall quality of product.
