Dexpan Customer Reviews

Stairs

"This product is amazing.
The hardest part is drilling the holes (very dusty). Destruction of my concrete stairs was complete. I followed the instructions as close to the letter as possible and the product delivered.
My steps did have some 1/2-inch horizontal rebar which was no problem."

Rock in Basement

"The product worked really well, and I didn't have to use a jack hammer. Definitely made my life easier and the job was completed quickly and efficiently."

Great Product

“Great stuff, but make sure you get the right temperature rating and watch out for rain. Otherwise, I’ve had great luck splitting granite rock with this product.”

Repeat Customer

"I've used Dexpan on two different concrete demolition projects and it is very effective when used as instructed. Hole patterns are very important for achieving the desired result so that part is up to the user. Drilling holes, filling with demolition agent and letting it work overnight certainly beat using a jackhammer for hours!"
