Urine smell in the barn

[nelson castro]

Have you try using plastic grids that locked together and then put larger gravel underneath, flattened that gravel, then put the grid down and covered it with pea gravel or smaller gravel after that leveled that to the top of the grid, then placed sane a few inches on top of it, then your bedding. The grid makes it impossible for them to destroy the gravel bed meant for drainage. The sand will allow whatever wet to pass through down through the gravel and away from the stall. It is best, if at all possible to drain the bottom of the stall through a tile or trench with gravel to an outside location to pull it away from the stall.
