Shipped to your door!

No need to head to the big box store for two heavy bags of concrete, strain yourself loading them into your trunk, and wear yourself out carrying and mixing them. Our one-post kit weighs just under 4 lbs., making installation quicker, easier, and less demanding.

Simple to use

Pour the contents of Bottle A into Bottle B, secure the cap, and shake for 30 to 40 seconds until fully mixed. Once ready, pour the mixture into the void and let it do the work.

Postloc Post Setting Expanding Foam A and B Bottles

Quality Ingredients

The two-part urethane foam expands 15 times its original volume and sets in 15 minutes. Best of all, it’s simple for anyone to use: just mix the two bottles, shake, pour, and watch it set.

Lasting Results

Postloc is a closed-cell urethane product. It does not float or degrade in water, but stays solid and holds firm even in marshy and wet areas like culverts. It even keeps groundwater clean, as the foam bonds directly to the pole and prevents wood treatment used on most poles from seeping into the soil.

Fast Shipping

We know that time is of the essence when it comes to shipping. We work with trusted carriers to provide reliable and efficient delivery services that meet your needs. Our shipping process is streamlined and optimized to minimize the time between order placement and delivery.

Postloc was a lifesaver for our DIY project. Fast, easy, and it held the posts strong—no mess or fuss!

Postloc has saved us time on every job. The foam sets quickly and offers a rock-solid hold, which means faster, more efficient installations. It’s been a great investment for our team.

As someone new to setting fence posts, I was a little nervous. Postloc made the entire process incredibly simple, and the posts are solid and secure. Highly recommend!

I was skeptical at first, but after using Postloc, I’m convinced. It’s so much easier than mixing concrete, and the posts are locked in tight. Definitely saved me time and effort.

We’ve used Postloc on several of our commercial properties for both flagpoles and fences. It’s consistently fast, reliable, and holds up better than concrete. Excellent product for any job!
