What Is a Reno Mattress Used for, and What Is Its Purpose?
If you want to learn more, please visit our website.
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.

18 Aug 23 15:45Hi all,See below image. Is there a standard connection detail for connecting a reno mattress (riprap apron) to a concrete headwall.The ground downstream of the outlet is sloping and I dont want any movement of the reno mattress.Have considered fixing U bars into wingwall base and U bars at top of mattress and interlocking but not sure if its the best detailAlso considering posts into the ground and tying mattress into them.

18 Aug 23 17:54instead of (or in addition to) connecting to the structure, anchor using either metal posts or using a gabion anchor trench / cutoff wall.

18 Aug 23 21:10I would think that you would want a seal to prevent water from entering under the 'mattress', but I'm not sure.

18 Aug 23 21:19cvg - thanks have also considered that. Need to do some excavation work so burying a 1m deep gabion basket and tying into that is not much more work. Although,I feel a U bar connection is the easiest and quickest but doesnt seem to be much on that type of connection online. I will give Maceferri a call on Monday.
Dik - tbh water is going to get under and in and around the mattress as its placed at outlet. Hoever hopefully flows are reduced so it doest cause any erosion!

21 Aug 23 03:25The Gabion manufacturer (Maccaferri?) are normally able to assist and review designsYour sketch looks pretty steep. Have you done a calculation to assess flow velocity vs scour velocity of bed material at the end of the gabion basketIf there is a big drop i would propose the following (alternatively you could concrete the gap at teh top):

21 Aug 23 16:27Providing an attachment of the wire baskets to the slab/cutoff wall would be difficult, since the wires are fairly small. Possibly, you could embed welded wire reinforcement into the slab and extend it out where it would lay under the gabion mattress.Another option to consider is using precast articulated block mattresses, instead.They have cables, which are easier to connect to the CIP concrete.

21 Aug 23 17:03That concrete headwall needs to be contoured better and provide some sort of overhang.Also maybe add some deflectors in the concrete slab to beak up the flow.Seen this? https://dcd.kitsapgov.com/ordnances/stormwater_htm... Some pretty similar things hereA lot depends on flows, velocities slopes and ground conditions to anchor the mattresses.

24 Aug 23 14:10Thank all, I spoke to someone at Maceferri and they recommended a very simple fixation of hammering in 40mm dia L bars through the mattress, to 1m below the matress. The mattress is 0.5m thick so bar length is 1.5m. One row at top of mattress at 300mm c/c and one row at mindpoint of 4.8m long mattress
I was expecting something more but apparently its a common method to fix them in slopes. (The actual slope isnt as steep as I have shown, its maybe 15 deg. )

24 Aug 23 14:19It's often fairly basic engineering from those guys....Hope you can hammer them in though?

24 Aug 23 15:23'L' bars may be a little tricky to 'hammer'.

24 Aug 23 15:44And that's a pretty thick and heavy bar. a 1.5m bar will weigh nearly 15kg.... you have to keep that upright whist you hammer it through 0.5m of mattrass and 1m of unknown ground. every 300mm. Someone isn't going to like you.Make sure they machine the end into a point and get a machine ready to hammer them in....Or someone who works out a lot and give them a sledge hammer.

24 Aug 23 15:56Initially they recommended 32mm but I questioned the durability since its in marine environment, so it was use 32mm galvinsed or upsize to allow for corrosion and go with 40mm.
But very fair points re hammering them in, I did think of the issue of hammering the L shape. I suppose you could tack weld a small straight portion on top of the L and then use a pneumatic hammer to install. Then grind off the temporary straight bit.

24 Aug 23 20:07in the past - i hammered in regular steel fence posts and then tied the mattress to those posts. i believe it was a grid at 1 meter spacing
we were unable to drive some of the posts all the way, so they had to be cut off flush with the top of gabions

8 Sep 23 14:44Interesting topic, I know i am a bit late but FYI:
We like to pin to the outlet of the culvert so if there is erosion or settlement it stays connected to the outlet. We have used stainless or galvanized eyes anchored into the concrete at the top of cut-off wall or bottom of wingwall, etc... We also spec out high survivability Filter Fabric under the gabions. Note, I have seen the aftermath of the failure of soil anchoring pins and the outlet of the culvert was almost lost.

8 Sep 23 19:42It actually looks like we are going back to connection to head wall as the riverbed is a lot softer than anticipated.
The proposal is the include a rectangular plate with some holes within the mattress. The holes are to receive bolts chemically fixed to headwall
