The other day I was driving down Pacific Coast Highway (PCH) in Malibu, I looked up and I noticed an entire hillside had brand-new brick work to hold back the mountain from erosion and mudslides. Obviously the homeowner did not wish to lose his home, driveway, or half the mountainside onto PCH. The work which was done looked quite stellar, and well-engineered. Of course, if you wish to do stone and brick work in your own backyard to stop corrosion you might try a similar strategy albeit on a very much smaller scale. Okay so let's talk about this for second shall we?
You do not need anything is elaborate as the Chocolate Hill rice terraces outside of Manila in the Philippines. Nevertheless, this strategy does work, and if done correctly it can hold back plenty of water, and prevent mudslides. Best of all, it's not as difficult as you might think. If you are considering doing something like this at your own home, there are many new spacing materials you can use between the stones or bricks.
This will allow you to use rocks, stones, or bricks other than the regular 3-D rectangle shape and then driving rebar down deep and through all the bricks, and then filling them in with concrete. Oh sure, that way works also, but it just doesn't look as decorative if you are doing something for your backyard, and you wanted to blend in with the landscape. Don't get me wrong, you might like that style with multiple layers of straight brick walls perfectly terraced.
Still, allowing for a little styling and the proper interim spacing materials sure looks brilliant. You might even use cobblestone, or decorative rock. If you are having problems conceptualizing this, I suggest that you go on to Google Images and look and see what other people have done, and then go to your local Home Depot, or Lowe's and talk to one of the landscape consultants about tricks of the trade. You can look through the brochures which come with your purchase, or you can go to a big box bookstore and look through some home improvement step-by-step instruction books.
No, I never said this would be easy, but if you follow the instructions, and play around with it a little, you'll surely get a sense of pride once it's completed, provided that you don't hurt your back from lifting the rocks incorrectly. Make sure you're healthy enough to do this project, because it does take a lot of work, and if you're new to the game, it will take you easily three or four times as long as it would a contractor who does this for a living. Please consider all this and think on it.
