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.

Double your bags per hole!

Would Not Recommend

Did not expand as much as advertised. Might be product age- these were mfg about 8 months ago.

Exactly as described

Would Recommend

Works exactly as described. Directions were clearly labeled. And very easy to use. It actually did set in less than five minutes for us when replacing a fence post.

Not as good as the brand Lowes used to have

Would Not Recommend

This did not expand nearly as far as the Sika brand they used to have. I need 2 bags now where I used to need 1. Barely expanded at all after following the directions. Picture is an 8" hole about 24" deep. Chart on the bag says 1 bag is enough. It's barely halfway up.

Avoid this cancer

Would Not Recommend

mixed, poured per manufacturer instructions with resulting yellow fluid pooling at base of post hole. A great product for wasting time and money

I would not use this product again

Would Not Recommend

The visual examples of how it should expand, videos that I watched and the instructions that I followed closely, the mixture did not expand like it said it would. At best I would say it expanded nearly 1/3 of the way of the 30 inch post hole that I dug. I dug three post holes and all three reacted exactly the same - very poor expansion.

IF only a small area needs to be filled maybe ok

This product was ok but didn't work as we thought it would. It was supposed to expand a good bit and fill the holes we needed filled but didn't do what we thought. It didn't expand very much at all and we were not as pleased as we had hoped.
