[QUOTE="gman4691, post: 1822424, member: 43107"] The bentonite some mentioned is a clay mineral and is very effective in taking water into it's crystalline structure at the molecular scale. It swells quite a bit when wet. Have used bentonite pellets and bentonite grout in groundwater monitoring wells many, many times back when I worked as a hydrogeologist for an environmental consulting company (did that for about 8-1/2 years). One of those little pellets can swell to the size of a baseball when wet. And the stuff gets pretty slick when wet. Should be a good seal to prevent seepage through soils around the culverts if covered over with some other material - like someone mentioned with a leaking pond earlier in this thread. Around here, crushed limestone makes an excellent base for driveways or even as the top layer. Which is strange because there is no limestone around here - it has to be brought in from elsewhere. Had a bunch of it put on our driveway and the road leading down to the pasture last year. It has compacted and held up very well thus far. Also used it over the soil on my culverts and the slopes leading down to them on both sides. Very pleased with the results. Note: The cows don't care to walk on it and will go around it if at all possible. They are used to walking on these red clay soils which is a much softer surface. The downside is that these soils can get pretty dang muddy when it rains which is why I had the crushed limestone brought in in the first place. Makes going down there to feed in the winter much easier...a huge improvement compared to what is was before. Well worth the cost. [/QUOTE]
