Review: dosent work as expected - We expected to demolish the colomb fadter as show in the video but it give 10% only
Review: directions need to be read and understood, it has a danger to users in hot weather. it expands! that said, the smallest hole i filled was a 3/8 to remove concrete from metal poles so that they could be reused. i also drilled 3/4 holes to break up thin walls for repair to the unit. it works over night in cooler weather, but you will see the start of the fractures in about 8 hours. silent destruction, (apart from the hammer drill) good stuff, experiment and learn how to use before taking on larger projects.

### ⭐⭐⭐⭐⭐ Review
*by A***Y on 14 June 2025*

This stuff is incredible. I was skeptical at first but am very pleased. Tried it on a basketball sized rock in an annoying place on the driveway before I do my big project. Drilled a 4” deep x1 1/8” hole hoping to just blow the cap off the rock so I wouldn’t hit it with the tractor while snowblowing. Came back next day and it was in three chunks! Very pleased. Note that instructions recommend pouring it first thing in the morning, so it has a chance to work during its “critical eight hours“ during the heat of the day. I was too cheap to buy a 1 1/2” bit, got the 1 1/8” for half the price. Seems to be working fine in the limestone I am dealing with. VERY HAPPY with this product. It is allowing me to turn a skidder trail into a road passable by cars and minivans. I have fractured a couple rocks and carefully blown the top 8” slab off others just by changing my techniques. WISH I NEW ABOUT THIS STUFF YEARS AGO!?!?! Why doesn’t Dexpan tell people about their product. BE PATIENT! Results after 48 hrs is always better than 24
