A bolt setup would be totally different, as it's just 2 small bolts. When we have multiple plates spaced perfect distance from eachother, and each cell relying on the spacing of the other (ie. if one cell gets expanded, the cells beside would be compressed) it is much different. With bolts, we can have them move, etc. Ever see in a huge lake that has breakers or something so that the waves aren't as choppy in towards the beach...When the winter comes, and it gets to about freezing temperature, they will throw in tons and tons of wood. Like 4x4s and 6x6s and stuff in small 4 foot pieces or so. They'll basically throw in any scrap would they can get. I'm referring specifically to a lake we have in town (I know lots of places do this). They have a cement barrier that they built up for a road by the lake. And as I said, there are water breakers a few yards into the lake all around. Well, they throw the wood in so that when it does freeze (because it definitely will, and expand greatly), the wood will absorb the expansion, and not let the ice damage the cement barriers. CEMENT! Just like on the sidewalks and any other cement road or anything where they put those spacers every so often. This is for expansion. That ice is something you definitely can't mess with. We just have to get around it somehow
