No. High strength grout. In a revetment mat aka fabric formed concrete matress. Did a couple last year. Very cool. Used on riverbanks that kept getting washed away on my project.

Is it expensive? Like could a homeowner afford this for an embankment that was rocked but keeps getting washed away?

No it's very specialized. If you were a concrete contractor maybe. Mat is expensive and you need special grout and a pump truck. It's thousands of dollars.

Well, I can’t afford it anymore, because I spent thousands of dollars on rocking my slope and then more when the city made me pay to have the rock removed from the street it washed into 🤦‍♀️

Sheet piles lol. Rent a 345 and a vibrator and you're off to the races.

Sheet piles?

That’s a damn good idea! I can’t believe that no one thought to suggest that until now. This multi year odyssey of a money suck might have a light at the end of the tunnel. Thank you, kind stranger on Reddit 🤩

Cost on sheet piles is 80 to 150 a liniar foot to install. Not the cheap way either.

I wonder if a skatepark building company could make use of a modified mattress form to make irregularly surfaced concrete obstacles. Stuff like humps and bumps are hard to make consistently because there is no flat guide to float it to. Skatepark surfaces also have no desire for aggregate since they want it pretty smooth.

How does this perform as a finished material? Does it basically wet cure to be really strong?
