The 3 D’s of Water Control
We’ve discussed the “3-D’s” of in-water construction, repairs, and inspection before, but we’d like to give you a slightly more in-depth explanation on this subject. There is a difference and each job requires different solutions in order to safely, accurately, and punctually get the job done.
De-Watering is also known as un-watering and it is great for controlling the submerged area of construction and providing a drier work environment. Ground or surface water is typically drained from one section and relocated temporarily to another until such a time as dryness is no longer needed, then it can be restored. When the unnecessary water is restored to its original location, it’s as if no disruption had ever happened, and that’s part of the beauty of using this technique.
Uses: below-ground spaces, foundation work, structural repairs, shoreline restorations, in-home overflow, pool servicing
Damming can be used to hold back light to heavy amounts of water, depending on the material being used. Beavers are natures best known dammers, and it’s part of their natural instinct for good reason! By using a Dam-It Dams inflatable cofferdam, a water-tight barrier is created that stops water from rushing onto the work site and contain the flow of waterways. Damming can also prevent water from crossing an established safety threshold.
Uses: pool servicing, personal pond restoration, flood control, dredging, environmental protection, river crossing
Diversion is sometimes permanent but more often than not, it is a temporary solution to your water problem. With this in mind, this techniques is used to simply reroute the water from its original location to a more convenient (or at least, less inconvenient) placement within the work area. Cofferdams can be used to create a sort of embankment in order to direct the water to a region of the work site that is no longer in your immediate way. The controlling of the flow and direction of this water is extremely important
Uses: spillage, flood control, in-home overflow, structural repairs, wetland protection
