What foundations are required to install the TWIDS?
Foundations serve a multiple purpose: They assure the rigidity of the carrying posts, the assure that the carrying posts will net change their position due to the heavy pull on them, and thus interfere with the working of the TWIDS, and, in the case of a concrete underground strip, they prevent digging under the fence. Each foundation requirement must be given careful design consideration which will depend on, in part, the terrain, the type of soil, the height of the fence, etc.
