How to break concrete or crack, split rocks easily?

There are only 3 Easy Steps to use Dexpan: Drill, Mix, and Pour.

Always wear Safety Goggles, Rubber Gloves, a Dust-Proof Mask, and Proper Clothing when handling Dexpan.
Forceful Blowouts and Alkaline Burns may occur. Make sure to read safety precautions and first aid at the bottom of this page.

 

STEP 1: Drilling
Use a 1-1/2 inches (or 3.8 cm) drill bit; holes should be drilled 1 foot (or 30 cm) apart. 80 to 90% of the depth, do not go through. Note: Using smaller drill bit will reduce expanding strength. Please call for applications with depths less than 6 inches. (See common

Use a 1-1/2 inches (or 3.8 cm) drill bit; holes should be drilled 1 foot (or 30 cm) apart. 80 to 90% of the depth, do not go through. Note: Using smaller drill bit will reduce expanding strength. Please call for applications with depths less than 6 inches. (See common drilling patterns

 

Tip 1: To insure success, Dexpan® needs empty space to expand to. Make sure that the rock or concrete has an open face for expansion equal to the drilling depth. If there is no expansive space, extra holes may be required to establish it.

 

Tip 2: Dexpan® cracks according to drilling patterns designed for controlled demolition and Easy Clean up. Call for our Free drilling patterns to minimize consumption of Dexpan® by cutting rocks or concrete into desired sizes.

 

If you encounter rebar while drilling, move drill bit a few inches to avoid drill bit damage.

 

STEP 2: Mixing
Choose correct type of Dexpan® based on ambient and core temperature. Core temperature is the temperature inside of the rock or concrete, which can be different from the ambient temperature.
In a bucket, combine 0.4 gallons (or Three 500mL bottles) of cold water with one 11 Lb. (or 5 Kg.) bag of Dexpan®. Mix well to a slurry, no lumps. A drill and paddle is recommended.

 

STEP 3: Pouring
Dexpan® slurry should be poured into holes within 10-15 minutes after mixing.
DO NOT leave excess Dexpan® slurry in the bucket as blow-outs may occur. Dispose of waste according to federal, state, and/or local regulations.

 
Coverage: Normally one 11 Lb. (or 5 Kg.) bag of Dexpan® can fill up to 9 lineal feet (or 2.5 meters) of 1.5 in (or 3.8 cm) diameter holes.

 

Tip 3: Clean holes after drilling using an air hose or vacuum to remove excess dust, this is not a requirement, but is recommended for best results.

 

Tip 4: Be sure to protect the filled holes from direct sun light, rain and snow. If water might get into holes, then Dexpan® slurry should be poured into plastic tubing.

 

Tip 5: For horizontal holes, you may mix Dexpan® thicker and push it into horizontal holes.

 

Dexpan® Cracking or Breaking Time:
Properly drilled and mixed, the cracks may appear after 2 to 8 hours of filling, depending on ambient and core temperature, humidity, rock or concrete hardness.
Note: Although the Dexpan® slurry may look dry on top, it does not mean it has stopped working, please allow the full 24 hours before calling our technical department.
Do not remove Dexpan from the holes or try other methods, these could void your warranty.
If Dexpan® completely dries into a powder and did not crack, pour additional water onto Dexpan® filled holes to restart the process.

 As you can see after 6 hours, hairline cracks appear in this concrete foundation filled with rebars.

 

 2 hours after, cracks are getting wider and deeper.

 

24 Hours after pouring, Dexpan® cracks are well developed and the concrete is ready to be disposed of.

 

Cut off exposed rebars, even they could not stop Dexpan from Breaking this concrete foundation.
