Engineering

• Timber Piles – Cutting/Drilling
With our air operated chainsaws and hydraulic drilling system, we can cut 12” x 12” timber piles, and drill through 24” thickness of timber in order to bolt 2 piles together.

• Underwater Cutting
Using Thermal Arc (Broco) cutting equipment, we can cut sheet steel or tubular steel piles, as required.

• Cardox Rock/Concrete Materials Breaking System
Cardox employs the rapid expansion of of carbon dioxide to break down surrounding materials, ideal where explosives are not permitted.

• Removal of Sand / Silt
This can be achieved using standard airlifting equipment, or the use of the Hydrainer System, or even dredge pumps, we can suggest the best system for your project.

• Concrete
From mass concrete placing to masonry joint grouting – we cover the whole spectrum. Placing of concrete bag-work underwater is our specialty.

• Scour Protection
The assembly and installation of Maccaferri Gabion Mattresses has been a regular feature of our work over the years.

• Air Bags
We keep a selection of totally enclosed lifting bags and standard parachute bags for salvage and for other buoyancy requirements.

• H.P. Water Jetting
We can carry out H.P. water jetting of surfaces both above and below water. For underwater use we have the availability of an underwater gun with retro jet facilities. Another of our specialties is the cleaning of empty underground reservoirs, where all surfaces and columns are cleaned using H. P. water jetting equipment in a confined space environment.

• Search & Recovery
As with most diving contractors, search and recovery is a regular feature of our work. Our 5.5 metre Rigid Inflatable boat is equipped with Echo Sounding equipment and DGPS, and is a useful tool to enable us to carry out this type of work.
