What Customers Are Saying

The product provides a convenient and time-saving alternative to concrete for setting fence and mailbox posts. Many customers found it easy to use, with the product expanding and hardening quickly to securely hold the posts. However, some reported issues with the product not performing as expected, and it may not be as durable or suitable for larger or heavier applications as concrete. Careful following of the instructions and product limitations is recommended.

Takes a lot of product to fill a void.

I used the product to fill a gap between two floor joists......... approx. 2 1/4" high, 14 1/2 wide, and 4' long...... not that much different from a single 4x4 post hole. It took 3 bags of the product to fill the gap.... very disappointing.

Much more convenient than concrete.

I used this for deck posts on a large project. Used as directed, this stuff is an amazing two-part foam that dries hard and fast. It rivals concrete in my application.

Product worked perfectly to stabilize a loose mailbox post. Easy to use. We were ready to buy gravel to stabilize the post but an employee redirected us to this product. Excellent result.

Worked well for my post

Would Recommend

I used it to set a new post in a hole through concrete over a dirt hole that had a post in it before. Poured some in the hole and put the post in but the bag started getting hot while I was trying to squeeze it in the whole around the post but I got most of it in. It starts setting up quick, it says 3 minutes work time and that's about right. It expanded out of the hole and hardened into a sort of hard plastic holding the very post securely. I put tape on the ground around the post and that he...
