Customer Questions & Answers

Can I use dexpan to remove 2" of decorative concrete in the middle of stoop treads on concrete slab?

Can I drill less than 1.5" holes for dexpan?
Asked by: Vonny
You can use it. I'm sure that it will be strong enough. But since you are working in the middle of an area, the outward expansion might damage more than you want. The 1.5" hole will become about 2.5" over time. If its a weak material, you can probably go smaller holes, but not much smaller. It works using pressure which uses Pounds per square Inch. You need square inches.

if I use dexpan will the boulder break itself off and roll or just remain with cracks for removal?

Asked by: Phil
I was breaking apart concrete on fairly level ground. Dexpan cracked the slabs but it did not push the pieces far enough apart that they rolled off or fell away from each other. using a 2' prybar the pieces were easy to separate along the cracks.

44 lb. Box Type 2 (50F-77F) Expansive Demolition Grout for Concrete Rock Breaking and Removal is rated 4.7 out of 5 by 58.

I was drilling 1.5" holes, 18" deep. Each 11lbs bag would fill just about 6 holes. I'm breaking up large blue granite boulders that are still in the ground, and Dexpan has been able to fracture these no problem. You can even go much larger than the suggested spacing, but the individual pieces get larger. Fractures start as early as 24 hours, but I find that if you wait a full week, the gaps become larger, and make removal/separation easier.

The only problem I have with the product is the age... the box was labeled with 3/22/2016, which means it is a little over one year old by the time I received it. All expansive mortars have a shelf life of about one year, and after that it is not as effective as fresh. I know this because I purchased one metric ton of it from a Chinese supplier several years ago, and they told me about the age issue at that time. For $100 I expected something a bit fresher.

The Type 3 as well as Type 2 performed the same, it is not the air temperature but the rock temperature which I believe impacts the performance. I observed if the sun is not beating down on the rock and warming it up the time it takes to cure and crack is tripled. I also noted it helps to water the drilled holes as it cures otherwise it powders.

I have to drill a 1 1/2" hole, spaced about 12" apart, but it is relatively inexpensive, and no specialist or certification is required, compared to using explosives to break rocks. And this stuff really breaks them! You have to wait a day or two, and you have to make sure the rock temperature is in range.
