EROSION CONTROL SOLUTIONS
Fabric Formed Concrete offer a cost-effective alternative to rip rap and cast-in-place concrete.
Durable forms constructed of woven double-layer fabric are filled
with pumpable, high-strength, fine aggregate concrete (structural grout),
providing an economic and durable solution to erosion control.
The forms are highly effective for scour protection and repair,
foundation, environmental and marine construction applications.
SAM CAL’s installations are convenient and cost-effective because
they can be cast in place as easily under water as above, thereby
eliminating the need to dewater sites or waterways during installation.
APPLICATION
Fabric Formed Concrete is used to line or repair a channel or to protect landfill containment systems and repair bridge scour. Protection of a shoreline against storm damage with fabric
formed concrete structures delivers long lasting erosion control
performance. When used in
canals, channels, culverts and embankments, fabric formed linings protect
against the forces of flowing water and wave action.
Geosynthetic liners are safeguarded from mechanical damage in
landfills, reservoirs and other containment and capping applications.
UNIFORM SECTION LININGS
 |
Minimize friction coefficient (N value) for canals;
produces a relatively even surface for cleaning equipment to operate over
geosynthetic pond liners. Provides
a highly impermeable, high quality concrete lining. |
FILTER STYLES
|
Bank protection while relieving potential
hydrostatic pressure “lift.”
Filter Point Linings:
An effective permeable concrete lining for structures constructed
over firm subgrades with relatively low hydrostatic loads.
Filter Band Linings: An effective permeable concrete lining for structures
constructed over firm subgrades with moderately hydrostatic loads.
Both filter styles achieve lower velocities and
reduced wave run-up in more severe conditions.

ARTICULATING BLOCK MATS
| Cast-in-place cabled blocks are used for protection
from severe scour. For
structures constructed over soft subgrades or where revetment is exposed
to frontal attack by wave action. Mattress
protects coastlines, waterways, underwater pipelines, bridge piers and
marine structures from the destructive hydrodynamic forces of high
velocity flow, wind waves, vessel-induced waves or propeller wash.
Optional high strength cables threaded between the two layers of
fabric provide tensile strength. |
|
“OPEN” BLOCK DESIGN
 |
Allows for revegetation for environmental
requirements and/or cosmetic appearances.
An aesthetic and environmentally compatible erosion protection.
These mats are comprised of filled elements and unfilled areas,
allowing open areas to be vegetated.
“Open” Block Designs protect against periodic high flows and
are installed above the waterline. |
LARGE DIAMETER “BAGS”
| Individual, cylindrical forms that assume a flatten
cross section when filled. Meet
the requirement for economical cast-in-place armor and support units.
Prevents scour along shorelines or bridge piers and abutments.
Their ease of deployment and cost-effectiveness makes them superior
to stone rip rap. The fabric
forms can be positioned and filled from the surface in shallow water or by
divers in deeper water. |
|
SAM CAL installs several mat and liner styles for a
high degree of erosion protection of slopes, channels and canals.
All mats and liners are woven from multi-filament and textured
yarns of nylon, which allow excess mixing water to pass while retaining
cement solids. SAM CAL works
with leading manufacturers to acquire the highest quality, custom
materials on an optimum delivery schedule. |
