Rip Rap
Alternatives
Brock White offers new and innovative alternatives to Rip Rap to protect against erosion along shorelines, slopes and anywhere sediment is moved by water runoff.
FLEXAMAT
Flexamat® consists of 6.5” x 6.5” concrete blocks with a 2.25” profile that are locked together with high strength geogrid, forming a hard armor against erosion. The 1.5” spacing between the blocks gives the mat flexibility and allows for optional vegetation growth. Flexamat® installations are capable of handling high flow water runoff.
Flexamat® enables vegetation to be established while remaining a permanent erosion control solution. Eventually vegetation will cover the entire mat. The product can be used in a wide variety of applications including ditches, slopes, swales, shorelines and anywhere that water runoff erodes the soil.
Flexamat® is shipped in rolls and is easy to install. A smooth bucket on the excavator is used to unroll the mat into place. The mat is available in widths of 5.5’, 8’, 10’ and 16’.
ScourStop

The ScourStop transition mat is a 4 ft. X 4 ft. x ½ inch HDPE polymer mat designed with voids throughout the structure that allows vegetation growth while providing mechanical protection over erosive areas. Transition mats provide mechanical protection over highly erosive areas such as stormwater pipe outfalls, curb outfalls, over-flow structures and shorelines. Transition mats provide protection against much high shear stress and velocities than vegetation alone or rock rip rap. They are comparable in performance to Articulated Concrete Blocks.
TURF REINFORCEMENT MATS
Landlok® 300
Landlok® 300 Turf Reinforcement Mats (TRM’s) provide better long-term performance over traditional methods like rock rip rap and concrete paving. Landlok® 300 offer increased design life over first generation TRM’s that are netted, fused, glued or stitch-bonded. Its unique three dimensional pattern creates a thick matrix of voids that trap seed, soil and water in place for quicker and thicker vegetation growth. X3® fibers provide additional strength to double vegetation’s natural erosion protection abilities long-term.
Landlok® 450
Landlok® 450 stitch bonded Turf Reinforcement Mats are ideal for applications requiring immediate, long term erosion protection, vegetative reinforcement and water quality enhancement capabilities. They are made from 100% polypropylene non-degradable fibers and yarns and also feature a patented X3® fiber technology.
Propex Geotex® Pyramat®
Propex Geotex® Pyramat® high performance turf reinforcement mats are equipped to handle the most demanding erosion control applications. Patented Pyramat’s three-dimensional construction makes high performance TRM’s ten times stronger than traditional TRM’s. The 3D matrix of polypropylene yarns features X3® fiber technology which locks in seed and soil for permanent reinforced vegetation. Pyramat’s outstanding UV resistance makes it the preferred TRM in arid and semi-arid environments and other applications where soil reinforcement is needed but full vegetation is not expected.
Armormax® Anchored Reinforced Vegetated System
Armormax® Anchored Reinforced Vegetated System is the most advanced flexible armoring technology available for severe erosion challenges. Consisting of woven three-dimensional High Performance Turf Reinforcement Mat, you can count on the Armormax® system to hold its ground.
