Expands and Dries Firm but Flexible

A mouse actually chewed a small tunnel through concrete into my garage. I used this to fill the small channel to the outside to keep out the elements (and hopefully more mice). This stuff expanded fast, and a little more as it dried. It's fairly strong yet a little flexible. It's been in place for quite a while now and has held up nicely. I didn't use much, and was surprised to find that the tube/applicator for the spray can was easily cleared to use again. I'd assumed the product would expand, dry, and block the nozzle. I was able to just pull it right out and use it again later.
