Boulder wall erosion

Hey guys, question. I have two boulder walls on each side of my garage which is connected to the house. The boulder walls are "stepped". First row is about 2-3 feet high. second row about 4 feet back is sloped up to about six feet. Both sides are the same
It's a new construction about two years now. I find that after a good rain, I get sand on the driveway just below the walls. Mostly on the side of the walls that are up to the house/garage foundation. No morter was used, just the boulders.
My contractor did a nice job placing them, Big back hoe. He tamped and tamped. He didn't charge me much at all as like most budgets it's tough to build retaining walls without taking aout another loan. lol Seems very sturdy and strong. Boulders have not moved or shifted. I just started planting some things in between the two tiers.
This erosion is not that impressive, but its more of a nusiance with it on the driveway it's 100% sand. Anything I can do to help stop it? And I am concerned about too much of this erosion over time. As I just keep sweeping it up and ditching the sand. I wonder how much is too much for the stability.
Thanks,
Tom

7 years ago, I had my contractor do the same thing, but I have soil, now and again wash out a bit. (critters help it too!) It took 5 years at least for this all to settle in. In the meantime, I planted alot of shrubs on top, and numerous other plants in all the nooks and crannies. Their root systems help hold everything together. At first I used the local erosion control (daylilies) and replaced them as I bought and moved more plants about. If you email me, I might be able to dig up some pictures of mine. In the meantime, hang in there, there is nothing like a natural stone bank! |
