We operate throughout Oceania Islands, with the capacity to stay working at remote locations
DEMOLITION, EXCAVATION, TUNNELING TRENCHING, BLASTING
In-Land, On Shore, Off Shore
ABC Diving and its subsidiaries provide civil services to the MARINE DEMOLITION and MINING Industries in a wide variety of projects throughout Oceania
Demolition, Excavation, Tunnelling, Trenching, Blasting…
- We operate Diamond Chain Saw Hydraulically driven and Ultrathermic Cutting Rods for cutting almost all materials
- We implement HYDRAULIQUE TOOLS for breaking and drilling (breakers, sinker drill, etc.)
- We can use WATER JETTING to make shore and underwater excavation
- We use also AutoStem Non-Detonating safety cartridge environmentally friendly (no shock wave) with a VOD of only 340 m/s and energy of 5,121 j/g (compared to 2,500 j/g in packaged explosives)
- We use SEMTEX RAZOR Flexible Linear Shaped Charge (FLSC) to produce a linear cutting action upon detonation, with a VOD of 7,900 m/s; when a reliable and fast cut is required, our FLSC is used to sever a multitude of materials.
The Stanley SK58 Sinker Drill is a heavy duty rock drill designed for drilling underwater in concrete, rock and masonry.
Weight: 32 kg. Drill capacity: 3″ (7.6 cm) diameter hole, up to 20′ (6 m) deep.
ENVIRONMENTALLY FRIENDLY (No Shock wave, almost no vibration):
With only one cartridge, technology based on a non-explosive chemical compound.
Its form of combustion is called ‘DEFLAGRATION”, which in comparison to high explosives (detonation),
NON-Detonating safety cartridge are environmentally friendly
WHY Non-Detonating safety cartridge?
Because there is no ‘explosion‘ and almost no vibration, resulting in no impact on the environment.
Theses safety cartridges are ideal for weakening and demolishing ROCKS and CONCRETE.
Used not only for ROCK BREAKING but also a variety of other applications including SHAFT SINKING, Pier/footing EXCAVATION, TRENCHING for pipelines and non detonating BLASTING in sensitive areas
How it works?
These cartridges are electrically fired self contained gas producing devices that break rock or concrete using gas pressure.
When a cartridge is fired, its contents rapidly burn producing high gas pressure.
This gas then works into any existing cracks or micro fractures from drilling.
The cracks widen, the work breaks apart and the gas pressure quietly vents away.
The UNDERWATER SAFETY CARTRIDGES we use are suitable for DEEP-SEA applications and ideal for controlled and sensitive environments.
These Underwater Safety Cartridges can DEMOLISH ROCK formations and CONCRETE constructions without creating shock-waves, heavy vibrations or pollution.
Advantages?
This method has many advantages over other products: It is instantaneous, it produces no Shockwave, very low ground vibration, little noise, and minimal fly-rock. The small amounts of fly-rock produced can be eliminated with wrapping.
This technology reduces the amount and size of the machinery needed for such demolition work considerably.
Our emphasis is on SAFETY not only to INDIVIDUALS but also to the ENVIRONMENT.
That category of explosive Cartridge has been classified as Hazchem class 1.4s with UN number UN 0432. Special permits are not required
Cartridges storage and transportation are easy. Please feel free to contact us, should you require any further information.
UNDERWATER DEMOLITION project:
Blasting to reduce in size a very dense limestone plate in front of a private jetty (very sensitive area)
SEMTEX RAZOR Flexible Linear Shaped Charge
SEMTEX RAZOR produces a linear cutting action upon detonation, with a VOD of 7,900 m/s.
When a reliable and fast cut is required SEMTEX RAZOR is used to sever a multitude of materials (e.g. Pier steel piles with or without concrete inside, Shipwrecks difficult access, etc.)
