Traditional Methods |
DEXPAN Non-Explosive Controlled Method | |
| COST |  Waste of valuable stone. Permits, training, storage, transportation and high insurance rates |
 It is possible to save up to 20% in comparison to blasting when DEXPAN is used properly (Diagram 1 shows how). Plus possible 100% increase in valuable Building Stone yield. In total, DEXPAN may save you thousands of euros. |
| SAFETY |  Poor safety is always the biggest problem of blasting. Explosions can cause noise, flying rock, dust, toxic gases, vibration, fire, serious injury and/or damage to expensive equipment. Regulations are restrictive |
Product safely breaks rock with extreme expansive capability when mixed with common water. NO noise, NO toxic gases, NO flying rock, NO vibration. Earth-friendly product can be flushed away by water after use. MSDS and instruction guide are available. A pair of goggles, rubber gloves and dust-proof mask is all that is recommended |
| SAVING valuable Stone | Blasting causes 15%-30% of wasted stone due to blasting into useless small pieces. This means wasting of thousands of euros. |
Controlled quarrying method makes it possible to quarry your valuable stone almost WITHOUT any waste. It is ideal to quarry big blocks of valuable stone or dimension stone into desired dimensions. |
| Training and Usage |  Professional training or hiring of blasting contractor is necessary. Both are costly. Usage is complex and dangerous |
3 easy steps to use DEXPAN, drilling, mixing, pouring. Homeowners are using DEXPAN worldwide with little or no training other than the instruction included or by telephone. No need to hire any contractors |
| Permit and License | It is necessary by regulation. Procedure of getting a permit or Licensed blaster is complicated and costly |
Non-Hazardous product works by providing silent cracking. NO permit or license is required |
| Storage and Transportation | It is complicated to handle explosives. The costs of storage and shipping are high |
NO special storage needed other than keeping it dry. NO shelf life. Can be shipped / exported by air, ocean, ground |
| Insurance |  Insurance is required. Rate is high due to higher risks of danger |
 Insurance is recommended but not required |
| Controllable Breaking | It is possible but complicated. A blasting expert is necessary. |
Full controlled cracking by easily drilling holes for your desired design. You may also control the cracking time by mixing more or less water. |
| Working Time | Explosions are quick. But preparation is timely. |
Acceptable. The cracks appear in about 2 hours depending on weather, interior temperature of the rock. The cracks become wider with time (48hr+. expanding time). |
