Cofferdams are an essential part of dam construction, and at VTS, we have experience in installing many types and sizes of temporary structures. From robust cellular cofferdams to cost effective Portadam™ systems, we have the expertise to find a solution to fit any project. We have a full service fabrication shop and can create customized cofferdams that will optimize efficiency and safety.
Safety is paramount when working with cofferdams. There are many risks involved in installing and maintaining an effective cofferdam such as ice flows, current, vessel traffic, rock fissures, flood events, soil conditions and more. When working inside, crews are often in confined space conditions, requiring atmospheric monitoring and emergency response plans. At VTS, we are familiar with both large scale cofferdams such as cellular structures as well as small cofferdams such as box-type, and will create an effective safety plan for each individual project.
Precision installations backed by extensive underwater construction and engineering experience.
Rigorous safety protocols and quality systems ensuring compliant, secure work environments.
Cutting-edge equipment enhancing efficiency and performance for all installations.
Skilled divers and technicians ready to mobilize across Canada for fast, reliable service.
Maintaining an effective dewatering plan is crucial for the safety and efficiency of the crews. Effective seals and back up dewatering plans can mean the difference between the success and failure of a project.
We can install several types of cofferdams:
• Box-Type
• Braced
• Double-walled sheet pile
• Cellular
• Earthen
• Geotextile tubes
• Single-walled sheet pile
• Portadam™ Systems
The HCD50-200 core drill is the most powerful and easily manageable handheld core drill available. It is perfect for any handheld coring in difficult accessible places where rigs or electric drills cannot be used.
Drilling in concrete pipes, ventilation holes, or just any type of job where handheld is the fastest way to get the job done. It is unaffected by water, dust, etc., and is very popular for sewage installations. The fact that you can drill handheld up to Ø350 mm with no need for a drill rig opens a world of opportunities and massive time savings. However, for tough jobs, it fits in a standard drill rig.
The HCD50-200 has a built-in hydraulic torque limiter, which ensures max torque and no kickback, thanks to an automatic integrated security switch, which stops the core drill if the core bit jams. The integrated security is set from the factory and may not be disturbed.
The HCD25-100 core drill is the most powerful and easily manageable handheld core drill available. It is perfect for any handheld coring in difficult accessible places where rigs or electric drills cannot be used. Drilling in concrete pipes, ventilation holes, or just any type of job where handheld is the fastest way to get the job done. The HCD25-100 is extremely easy to use and will drill through any material. There is no need for a drill rig. However, the HCD25-100 fits in a standard drill rig with a 60 mm flange for more demanding jobs. The core drill has a built-in hydraulic torque limiter, ensuring max torque and no kickback if the core bit jams.
Ven-Tech collaborates with industry leaders such as AWWA, NFPA, Deep Trekker, BCWWA, ISNetworld, Cognibox and many more to ensure top-quality services. These partnerships reflect our commitment to safety, innovation, and excellence.
