Strengthening a Large Creek Bank
We received a call from a homeowner in Forreston, Texas. She wanted us to examine the creek bank in front of her house. The creek had seriously started to erode and her house was seriously getting closer to the creek. She was really worried about it falling into the creek if she lost a few more feet.
She got prices from several people for grading the creek bank smooth, forming it and pouring concrete over it. The problem with that is that if you grade the existing soil and loosen it, it takes a lot of concrete and a lot of work to stabilize the creek bank and make it stand still.
We went over all that with the homeowner. We explained that if we did it the bank would look just about the same as it did right then. It would have gullies and undulations and would, in fact, look like a creek bank.
In reality, it would be stronger since the undulations would help maintain its strength. The main reason for the concrete was to protect the surface from further erosion, and doing it according to the plan we laid out would cost less.
If you do something like this, you have to pin the edges because, in effect, you are putting a concrete blanket over the existing dirt surface, so you must pin that concrete blanket down. Using ground anchors, we attached it into the soil at the bottom, the top and all along the center.
