HARTLINE 10001 Rockite Expansion Cement 15 Min 1 Lb

Great value for the money. Works as expected. Seems to be durable so far. Easy to use and apply. Sets up pretty quick and dries fast.

I had small project . Just a hole in my yard from a old post hole for clothes line . I filled it was very easy to do and it worked out pawsome

A neighbor hit my mailbox/light post outside and it was tilting halfway over, filling it in with dirt was not enough to keep it upright. I choose this instead of concrete because it seemed less mess and hassle. It was, it's super easy to use and mix, and works perfect. My post wont budge now. I got a one gallon plastic water bottle to use as my mixing bowl, just cut the top part off. You need a throw away stirrer or spoon. You can make this as thick or runny as you want, there is no instructions. So add the powder first and slowly mix in water until desired consistency. I put 4 wooden wedges around the post and hammered them tight. Then I made half of the powder mix to be slightly runny but not too watery. I poured over the wedges and into the gaps. Let sit a few hours to harden. Then I mixed the other half and repeated the steps. I figured it was best to not have a really really deep pool that might soak into the ground before it all hardened. Now I will fill with dirt and hope no one else hits it :)

It works but is a bit tricky getting consistency just right

This product worked well for me. No clear instruction for mixing. I used 4.5 oz water per AI, but came out very runny. But I used it anyway to see what happens. It took several hours to hardend. To my pleasant surprise, it worked! You may want to use less water for better result. See photos.

This was nice quick and easy to mix. I used it for a mailbox post and it’s still holding up Good just wish I would’ve ordered more than one box didn’t realize it was a small box, but the little batch did its job

Terrible product. False claim about drying in 15 minutes. It has been hours and it’s still not solid. This is a waste of money. It’s cheaper to buy quickrete…..this small bag is worthless. False advertising

Strong hold /dries fast
