Past Projects

replacing pipes below the seabed

based on cost effective solution 

concrete slabs 

pouring concrete underwater to create sealed cofferdams for basements, underground train stations or tunnel boring machines is since 1990 a comment solution to create dry cofferdams

installation of mooring buoys

in soft or hard soil

i.e. U-Bolt , I-Bolt or Manta Anchor

water level is rising

to prevent cities from flooding 

we provide one hand solutions

deliver & install check valves from

measurement to

final installation

special solution for

replacing existing slide gates

at sewage plants

while in service

rental & installation

of pipe plugs for all different shape of pipes

easy and safe handling - lightweight

max. pressure 14.5psi

culvert inspection and cleaning without renewal is the most effective and cheapest solution to keep the water flowing

separating flurry suction mix

up to 600cy flow capacity

to separate sand/sludge and water

important solution for dredging of lakes, ponds, docks, canals and many more

to turn Archimede's Principle

is sometimes difficult

but mostly feasible

hydro blasting for demolition underwater with up to 36,000psi

concrete can easily be removed with water high pressure

hydro robotic

can be used in confined space

to remove roots, concrete or other obstacles with water high pressure

up to 36,000psi 

visualizing

of complex underwater structures

to proof existing condition
