## Description

Concrete Demolition and Rock Breaking has never been easier with Dexpan Expansive Demolition Grout. Dexpan is a powder with amazing 18,000 PSI expansive strength when mixed with water. Poured into drilled holes, Dexpan can break concrete and rocks safely and quietly, while providing SILENT cracking. It is safer, easier and more cost effective. Note 1) Not recommended for concrete slab less than 6" in depth. Note 2) You are getting one 11 Lb. Bucket of Dexpan which fills up to 9 lineal feet (2.5 m) of 1.5 inch (3.8 cm) diameter holes. Note 3) Choose correct type of Dexpan based on rock / concrete temperature. **PLEASE READ CAREFULLY BEFORE USE** **ALWAYS WEAR Safety Goggles, Rubber Gloves, Dust Mask** How to use Dexpan? STEP 1) Drilling: Use 1.5 inches (3.8 cm) drill bit, holes should be drilled 1 ft (30 cm) apart. 80-90% of the depth, DO NOT go through. STEP 2) Mixing: In a bucket, combine 0.4 gallons (1.5 liters) of water with one 11 lb. (5 kg.) bag. Mix well to a slurry. (a drill and paddle is recommended) STEP 3) Filling: *Warning: Use of Dexpan in extreme hot temperatures could cause blowouts. Dexpan slurry should be poured into holes within 10-15 minutes after mixing. Coverage: Normally one 11 lb. (5 kg.) bag can fill up to 9 lineal feet (2.5 meters). STEP 4) Cracking Or Breaking Time: Properly mixed, the cracks may appear after 2-8 hours. Allow 24 hours for best results. **WARNING** IMPORTANT SAFETY PRECAUTIONS and FIRST AID: 1) SAFETY GOGGLES, RUBBER GLOVES and DUST-PROOF MASK is required. 2) **WARNING** BLOWOUTS may occur! DO NOT look directly into filled holes. 3) Do not breathe in dust. Avoid eye and skin contact. If eye or skin contact should occur, rinse it off IMMEDIATELY with plenty of water and consult doctor. 4) Keep Dexpan in DRY storage. Seal box / bag after use. 5) Keep out of reach of children and pets. 6) MSDS (material safety data sheet) is available upon request.

Review: This product worked great for breaking apart a huge Canadian shield rock (a combination of granite and other rock materials) in our basement sized about 4 ft x 24 ft. We initially followed the instructions on the USA website, but it didn't work as fast/well as we'd hoped, so we checked out the CDN site and found out we were mixing it incorrectly. As soon as we started mixing it correctly, before pouring it into the drilled holes, we were seeing initial results before 24 hrs and after 48 hours, the rock was cracked & breaking apart easily. It took my husband a full month & a half after work & weekends to break it almost completely apart. Last pic is from 2 weeks ago, we are further now. We have just a bit left at the narrow 2 ft part & a bit around the edges. We are happy to almost reclaim a huge amount of square footage in our basement that we will use as a rec room in the near future. Great product, highly recommend.

## Questions & Answers

**Q: So i was just looking for a simple deilling hammer... all a sudden i see this stuff and wonder, how have i lived without this!? How dose it work?**
A: I purchased a case of Dexpan last summer to break up a large concrete foundation.  It did not work, we ended up hiring an excavator with a large jack hammer.

**Q: can we get this product in india?**
A: Yes

**Q: Would that work on tree stumps?  Drill a few holes, put in product and watch the stump break in half?**
A: I think it's unlikely that it would work on stumps.  Wood is much less brittle and less stiff than rock, so would probably just locally crush around the dexpan instead of splitting.  I would call dexpan tech support to confirm.

**Q: Which Do I use for a 30 inch thick piece of concrete at 92 degrees f**
A: All 3 types work the same regardless of depth. the only difference this product has is the temperature in which you can use it. So based on your core temp. of rock or concrete. If your in the 90's you more than likely will using the Dexpan 1. You always want to apply the product as early as possible. Drill holes and prep day before.  If you have any further questions or concerns feel free to call a Dexpan Rep.
