I bought these to help absorb melting snow and ice from my car after insulating my garage. You did your job. I had to place two of these over a joint in the concrete and drive over them. They held up pretty well but eventually went bust but given the circumstances I think they more than held their fair share of the business. And in a box of 50 I had a few more. I'll see if I can find another use for the remaining tubes. The only thing that bothered me was the drying time, but earlier in the year the temperature was still cool even in direct sunlight (Idaho). I think in the height of summer they would dry much faster.
