10 ft x 40 ft x 5 inch average thinkness concrete with rebar patio. 1. How deep should I drill the holes, and at what spacing? 2. I’m in northern CA, temp 60-70 degrees F* which type is recommended? 3. How many 11 lb bags are needed?
Asked by: Lyn
With that size slab, you might want to consider breaking it is up with a jack hammer. The demo grout won’t break up the rebar, you’ll have to use a saw or cutting torch for that. You will also have a lot of holes to drill to pour the grout into. If you are going to use it, I believe the recommendation is a hole every 12” in a grid pattern. I believe the grout maker said that it works best when the hole is 1 1/4” in diameter and at least 9” deep, but obviously on a 5” thick slab, that won’t be the case. So don’t drill trough the slab as you’ll likely lose the grout’s expanding effectiveness, maybe down to 4” to 4.5”. I broke up a granite boulder with this product, but this rock was at least 8 feet long and probably went as deep in the ground. No way I was going to break that up with a jack hammer. I went through (5) foot-long drill bits using a rotary hammer. But it worked so well. So for a 10 x 40 slab, you need 9 x 39 holes Multiply this number by pi x hole diameter (squared) x hole depth / 4 = grout volume in cubic inches Then multiply this by the density of the grout (units in lb/in3). This will give you the weight you’ll need. Then divide this number by the weight of one bag. This will give you the number of bags you need. The type 2 will be fine for your purposes.

44 lb. Box Type 2 (50F-77F) Expansive Demolition Grout for Concrete Rock Breaking and Removal is rated 4.6 out of 5 by 114.

Large boulders in the way of a new foundation. I tried a micro-blasting system with poor results. Jack hammer: too labor intensive. I read about Dexpan and tried it. The initial investment was daunting, but I went for it: Mikita hammer drill: $350, SDS-Max 1.5" bit: $93, Dexpan: $113. 44# easily filled 14 holes (1.5" x 18" deep). One set of holes had some "blow-out" because I didn't pay attention to the temperature; very important. However, even after the blow-out it cracked the rock over night. If you follow the instructions carefully, mix it thoroughly, watch the temperature and stand back, you should not have any problems. I will definitely order some more and keep going.

Rated 5 out of 5 by from DEXPAN SAVED ME HOURS OF LABOR Dexpan works! I had 20 feet of 75 year old "blue stone" concrete wall to remove. The walls were 26 in. high, 5 ft. long, 14 - 16 inches wide. The walls flared out at the bottom. No rebar, but blue stone is very difficult to chip away using jack hammers. Used a Bosch hammer drill to make the holes in the concrete. Started with a 3/4 inch pilot hole, and finished with a 1.5 in. carbide tip bit. I followed the instructions for drilling the holes, mixing the solution, and pouring it into the holes. I got the results I was hoping for. Concrete demolition with much less noise and dust then the traditional method using jack hammers. I'm happy! Neighbors are happy! This product saved me hours of labor! I rented a compressor and chipping gun to use as a Plan B and I returned them the next day, unused! I have 10 feet of wall left and I bought another box of Dexpan to take it down! I have contractor friends and serious DIYers that were very impressed when they saw the results.

Rated 5 out of 5 by from Fantastic product that works exactly as described. I wanted to build a koi pond in my backyard, but encountered giant boulders buried beneath the surface. I live on a mountain, mostly composed of solid granite rock. After days and weeks with a jackhammer and sledgehammer, I couldn't finish off some of the biggest, hardest rocks. I purchased Dexpan from HD and, after it arrived, I rented a hammer drill and, following the directions, drilled holes into the rocks. The largest one featured here is a whopping 5 feet tall by about 4 feet wide. After mixing and pouring the dexpan, the rocks began cracking in just a couple hours. By morning, the rocks were fractured, some in larges pieces that had fallen apart (see the last picture). This product does what only fire or dynamite could do in terms of demolition. However, this product, unlike the aforementioned, is safe, easy to use and quick to clean up. I highly recommend this product.

Rated 5 out of 5 by from works Used this in colder temperatures and could take as much as 48 hours to do the job. Found that in some cases a little rain the second day may have reactivated the materials as the next day the cracks were even bigger? Easy to mix read instructions where a good dust mask and face shield, mix with a slow drill to reduce splash in a 5 gallon bucket. the closer your rock temperature is to the limit the faster everything has to be done and it will start cracking sooner as well. drilled 1.5" holes 12 deep at a minimum. deeper if you have a machine to move large sections of rock. Packaging was a little shoddy as one bag was ripped and leaked out some material. use 3 - 500ML water bottles tear top of bag and fold over turn upside down and set into pail. Slowly pull bag out so as not to create to much dust. Add 2 bottles of water and immediately start mixing. be sure to hit all edges of bucket add 3rd bottle while mixing. I notched the bucket to give a better pour into small holes.
