Postloc is a two-part, high-density, closed cell polyurethane foam used to set posts and poles into the ground – fence posts, gates, mailboxes, flagpoles, basketball hoops, bird houses, satellite dishes and more.

Postloc is lightweight, easy to carry, and easy to use – eliminating the struggle that comes with heavy bags of concrete. Simply mix the two components together and pour into the hole. The resulting foam expands outward and locks the post into the soil around the hole, while also adhering to the post, creating a stronger foundation than other backfill materials, including concrete.

Postloc works with all types of post materials, including wood, metal, vinyl, PVC, concrete and fiberglas and also protects the post from decay and rust. It mixes in seconds and fully sets in 15 minutes or less, allowing you to complete your project in the same day. Postloc can be used in all seasons and is compatible with various types of soil.

BMK Corporation, the maker of Postloc, pioneered the use of polyurethane foam for setting utility poles in 1988. Today, BMK products continue to be used by major utility companies across the country to set and straighten poles, especially when time is of the essence during restoration of power after natural disasters. Postloc allows you to utilize that same proven performance and reliability for your projects.

Each box contains two kits – two bottles of Part A, two bottles of Part B (a total of 84 fluid ounces) and two pairs of chemical resistant gloves – everything you need to set two standard posts/poles up to three feet deep. Complete instructions are on the package along with a how-to video.
