Survey & Inspection

ScaffFloats are often used for inspections and surveys under bridges, piers and in other areas that can be difficult to access

Very often, due to the nature of the location, inspections to assets over water cannot be undertaken from standard modular pontoons and the cost of workboats or multicats can be prohibitive.

ScaffFloat pontoon can provide a safe and cost-effective alternative with a self-propelled platform that is stable enough to carry access solutions such as scaffolding towers, Monkey towers or water-level shelves. ScaffFloat pontoons can also be launched and self-driven to remote locations with limited water access.
