GABION "RENO" MATTRESSES
What Is a Reno Mattress Used for, and What Is Its Purpose?
A Reno Mattress is a gabion mattress for structural support and erosion protection. It consists of wire mesh encased in galvanized steel or PVC filled with soil and other materials. The mattress is rectangular for an even weight distribution for enhanced structural integrity. A Reno Mattress has various applications, including slope stabilization, stream bank protection, bridge protection, and erosion control. Their reliable, resilient structure provides exceptional structural integrity, preventing slippage or soil degradation.
They can be used in many different environments and soil conditions, making them the suitable choice for erosion control and the protection of slopes. This is because they are resistant to corrosion and degradation, thanks to the galvanized steel or PVC wire mesh material that encases them. DURA-FLEX Reno Mattresses are known for their excellent performance in all environments. They provide maximum surface protection, making them ideal for erosion protection projects.
From their sturdy hexagonal wire mesh construction to their resilient galvanized wire, these mattresses can provide your project maximum surface protection for years.
What Are Typical Applications for Reno Mattresses?
Reno Mattresses are ideal for numerous projects due to their superior strength and durability. We provide this engineering solution for various applications, including shoreline protection, embankment stabilization, bridge abutment stabilization, wing walls, and hydraulic applications.
Reno Mattresses are an excellent solution for hydraulic applications such as weirs. When used to protect rivers and streams, they form an essential line of defense that limits scour and stream channel erosion. Reno mattresses have longevity and low long-term maintenance.
Reno Mattresses are ideal for many applications, including permanent protection and support solutions. The convenience, affordability, and quality of these solutions are unparalleled. At Gabion Supply, we provide Reno mattresses with technical design services, competitive pricing, superior installation options, and comprehensive delivery solutions, so you can rest assured you’re in good hands with us.
What Is the Difference Between Gabion and Gabion Mattresses (Or Reno Mattresses)?
Gabions and Reno Mattresses are two popular solutions for flood control and streambank stabilization. Both systems utilize interlocking units filled with stone, but each solution has unique benefits. The primary difference is the size of the Reno Mattress: they are slightly wider and shorter than a traditional gabion.
Gabions are large baskets or cages filled with rock. They provide extra stability to steep or eroding streambanks and channels or dams with higher velocity flows. These cages come in many shapes and sizes and can fit virtually any terrain.
Reno Mattresses are similar to gabions but have a unique shape. They have interlocking cells, allowing them to adapt to irregular terrain, which makes them great for stabilizing natural shorelines or ponds. The hexagonal design makes them incredibly versatile and is ideal for areas with curves and bends.
Another advantage of Reno Mattresses is their use for large or small applications. Whether it’s for residential or commercial applications, Reno Mattresses offer a much lower labor cost than gabions due to their flexibility. Reno Mattresses also require less heavy equipment when installing because they are generally easier to place than gabions.
It’s necessary to consider the differences between gabions and Reno Mattresses when choosing a flood control or streambank stabilization solution. Gabions are great for high-velocity channels or dams, while Reno Mattresses are ideal for irregular terrain. Ultimately, the best option will depend on the needs of your project.
What Are the Benefits of Using a Reno Mattress vs. Other Options?
We often recommend these highly reliable structures to customers looking to protect their slopes from the ever-present dangers of erosion and scour. As these mattresses have one continuous mesh panel and no joints to weaken the structure, our clients get a robust defense against soil instability. The added advantage of the double diaphragm adds further structural strength to these mattresses and gives peace of mind to the user.
Reno Mattresses offer considerable benefits in embankment stability as they have a flexible form that adapts well to variable soils. These systems have high stability, yet their modular nature enables an easier installation and will generally take much less time to complete than conventional hard armor solutions.
The PVC coating helps strengthen the mattresses and protect them from weather. Its superior qualities enable the Reno Mattresses to match existing soil profiles and also allow them to act as a safe environment in which wildlife and ecosystems can regenerate. As a company focused on sustainable practices, this latter aspect of the mattresses has earned approval and admiration.

DURA-FLEX Galvanized Gabion Mattress
The DURA-FLEX gabion mattress is a mattress shaped container manufactured from heavily galvanized wire to form a flexible and effective surface protection to defend against erosion and scouring. The flexible wire mesh will accommodate significant deformation without failure. The base and sides of the mattress are made of a single sheet of wire mesh (main panel). Partition panels (diaphragms) are made of the same wire mesh as the main panel and are attached to the base of the main panel dividing the gabion mattress into 3 foot cells. The lid is formed either by a single sheet or in rolls of a specified length from the same wire as is in the main panel.
The mesh shall be woven into a hexagonal pattern with the joints formed by twisting each pair of wires through three and a half turns. Because of this appearance, the joints are often termed triple twisted. The mesh opening shall be hexagonal in shape and uniform in size measuring 2-1/2 inches by 3-1/4 inches.
All wire used in the fabrication of the gabion mattress and in the lacing operations shall conform to Federal Specification QQ-W-461H, Class 3, Finish 5, soft, and have an average tensile strength in accordance with the current ASTM A 641, Table 2, measured before fabrication of the netting. The nominal diameter of the wire used in the fabrication of the netting shall be 0.0866 inches minimum, subject to diameter tolerance in accordance with the current ASTM A 641, Table 3.
Tests shall be conducted on the wire before fabrication on the mattress on a sample 12 inches long. Elongation shall not be less than 12%.
All wire used in the fabrication and construction of the gabion mattress shall be galvanized according to ASTM A 641, Table 1. The minimum weight of the zinc coating shall be according to the table following when tested in accordance with ASTM A 90.
Nominal Diameter of Wire - 0.0866 in (2.2mm) minimum
Minimum Weight of Coating- 0.79 oz/sq ft
Mesh and Lacing
Selvedge
0.106 inches (2.7mm) minimum
0.80 ozs / sq ft
Adhesion of the zinc coating to the wire shall be capable of being wrapped in a close helix at a rate not exceeding 15 turns per minute around a cylindrical steel mandrel having a diameter 3 times the nominal wire diameter being tested. After the wrap test is completed, the wire shall not exhibit any cracking or flaking of the zinc coating to such an extent that any zinc can be removed by rubbing with bare fingers.
All edges of the mattress including end panels and the diaphragms, shall be mechanically connected in such a way as to prevent unraveling of the mesh and to develop the full strength of the mesh. The wire used for the selvedge shall have a diameter greater than that of the wire used to form the mesh.
Sufficient lacing and connecting wire shall be supplied with the gabion mattress for all wiring operations. The nominal diameter of lacing wire shall be 0.0866 inches minimum.
According to engineering and design requirements the mattress shall incorporate internal diaphragms to form cells having a nominal length of three feet. The internal diaphragms shall prevent rock migration within the gabion mattress unit.
The DURA-FLEX Heavy Duty Mattress was designed specifically to accommodate stone size of 3 to 6 inches (75 -105mm). Only hard durable stone shall be used as mattress fill.
On channel slopes, the mattress shall be placed perpendicular to the flow in the channel with the shorted dimensions of the diaphragm going up and down the slope. On the channel bed, the mattress shall be placed so the flow runs parallel with the short dimension of the mattress compartment, while the width of the mattress runs across the channel bed. An approved corner closure tool shall be used to adjoin adjacent mattresses to insure a tight, neat seam and minimize mattress wire joint deformation.
