EXPANDO is an expansive mortar chemical that cracks rocks and concrete, without using explosives. It is a concrete cutting, granite breaking and general demolition solution. This non-explosive demolition agent is easy to use, cost effective and a safer option for silently breaking up hard materials like rock or concrete. Simply drill, mix and pour.

You can find more information on our web, so please take a look.

EXPANDO non-explosive mortar is distributed throughout Australia including; Perth, Queensland, Northern Territory, Melbourne, Adelaide, New South Wales and South East Asia.

EXPANDO is distributed by No Blast Pty Ltd, leaders in Non Explosive Demolition.

EXPANDO is the ideal alternative to noisy, risky concrete and rock breaking solutions like explosive blasting, jack hammering, concrete saws and stone cutters &#; particularly on sites with noise restrictions, vibration issues, safety risks, confined spaces or environmental pollution concerns.

EXPANDO is an environmentally friendly, safe solution that allows you to reduce labour and equipment breakage risks and costs, improve site logistics and minimise safety, noise, dust and toxic pollution of the site.

EXPANDO is safe, environmentally friendly, and a non-explosive rock splitting and concrete cutting solution.

EXPANDO is a cracking agent that comes in powder form, which when mixed with water expands. When poured into pre-drilled blast holes, it produces an extreme pressure of 18,000 PSI. After a few hours the tensile strength of the rock or concrete are overcome by the cracking agent. The rock or concrete then breaks following the pre- drilled hole pattern.

EXPANDO uses pressure to crack rocks and concrete, there is no explosion, thus EXPANDO is a non-explosive demolition solution. The product is environmentally friendly and is made from calcium oxide (quicklime).

Silent cracking agents are not a new concept they have been used in rock breaking since the &#;s. Chemical rock splitting has been used extensively by drill and blast contractors as an explosive alternative for sites with vibration restrictions, rock fly problems or noise restrictions. EXPANDO can be used in an unlimited range of Expansive Mortar Applications.

Expansive mortar has been used successfully in mining and quarrying around the world for many years now. &#;&#;John quickly realised the opportunity to use non explosive expansive mortar as a demolition agent in other industries, after seeing it in use in Canada, where it is used extensively by miners as a cost-effective alternative to using dynamite to remove granite from the Canadian shield. &#;&#;The ever-increasing demand for non-intrusive, non-explosive demolition solutions, means Expando expansive mortar has vast potential to be used in a wide range of applications and industries in Australia. Due to its safe, environmentally friendly, controllable, predictable results. EXPANDO is not just limited to rock breaking, it is also used in concrete cracking and cutting.

Concrete Demolition and Rock Breaking, Cracking, Splitting has never been easier with Dexpan® Non-Explosive Demolition Agent. Dexpan® is a cement with an amazing 18,000 PSI expanding strength when mixed with water. Poured into drilled holes, Dexpan® breaks concrete and splits rocks safely and quietly.

  

 

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.
