The foam will certainly fill the gaps, but even once it sets, it's still pretty soft. It wouldn't provide any support. It might prevent further erosion, though **Q: Is this product closed cell foam?** A: Hello, this product is considered open cell. However, our open cell count is far less than any competitive product you will find on the market. So once it's cured, it forms an air and watertight seal. Thanks! **Q: is this fire proof?** A: Hi, no it is not, if you need our fire proof foam, I have posted the link for you below.
