Скачать или смотреть Pile Encapsulation (Column Repair) with Form-A-Tube

These 24-inch diameter steel piles were corroded over a height of 12-feet. The contractor used 14-ft long strips to extend 1-ft above and below the corroded zone. Fourteen strips were connected to create a sheet that was wrapped around the pile. This created a 14×2=28 inch diameter tube. Ratchet straps were used at 1-ft spacing along the height of the tube before it was filled with grout.

In this application, the ribbed surface is facing inwards and it locks into the grout, resulting in a permanent protection barrier (encapsulation) for the piles.
