Increases  P-WAVE Performance

DHDA™ is a pressure wave reflecting polymer that redirects the shockwave explosive power in the initial blast directly into the hard wall surface to dramatically increase fracturing to reduce rock size. By using DHDA™ numerous performance benefits are realised: reduction in time loading in wet holes; ensures ANFO option is available; reduces blasting noise and dust; reduces oversize equating to substantial down stream savings.

Why use DHDA™?

• Easy to pour down blast holes
• Rapidly drys and solidifies invasive down hole water
• ANFO can be used instead of emulsions
• Increased P-WAVE performance upon detonation
• Reduces multiple operational costs

Key Benefits:

• Easy pour granulate into blast holes
• Simplifies bench loading procedures
• Rapid solidification of water
• Effective across varied water qualities
• Protects ANFO from dynamic ground water
• Can be used with all explosive types
• Creates P-WAVE reflecting deck
• Improves blasting results
• Saves time and reduces costs
• Non hazardous and non dangerous

Typical Dose Rate

• 100 grams per litre of normal ground water. Increased dosage is required for high TDS water. Product applied at 50 grams per second.
• Use Anfo - Not emulsion
