Underwater blasting is an excavation method that fragments rock and concrete structures on sea, lake or river beds in a controlled way, without harming the environment or aquatic life.
Technical features
- Controlled blasting that reduces environmental impact
- Special measures to protect marine life
- Explosive systems rated for high water pressure and waterproof detonator technology
- Underwater imaging and monitoring technologies
- Operations planned for wave and current conditions
Application areas
- Port and quay construction: excavation and foundation preparation on the seabed
- Dam and hydroelectric projects: underwater rock excavation and tunnelling
- Bridge piers and viaducts: foundation excavation and rock clearing on river and lake beds
- Immersed tunnel projects: safe excavation at underwater crossings
Experience
Our founder Rıza Sağlam gained expertise in underwater blasting applications in Uruguay, South America.
Frequently asked questions
Does underwater blasting harm fish?
Underwater blasting can harm fish and marine mammals through pressure effects. Measures such as timing that avoids sensitive periods, smaller charges and bubble curtains reduce the effect; work nearby often depends on permission from the competent authorities.
Which projects use underwater blasting?
Port and quay construction, dam and hydroelectric projects, bridge pier foundations and immersed tunnel crossings are the main application areas.
Do waves and currents affect the operation?
Yes. Wave and current conditions affect the safety and planning of the operation, so it is planned around them.
What monitoring is done in underwater blasting?
Underwater imaging and monitoring technologies provide continuous control throughout the operation, and planning follows wave and current conditions.
