Grouting Project
Underwater grouting is performed when repairs are needed for bridge piers, intake structures, dams, canal walls, Sluice gate mounting plates, voids in the walls and floors of concrete structures and filling of bulkheads during ship salvage. Placement of concrete, cementitious grout, epoxy grout or underwater mortars is done through a variety of methods such as concrete pumps, mini grout pumps, tremmie tubes or by hand. Some methods of grouting involve the installation of formwork to contain the material prior to the placement depending on the location, size and type of structure where the materials are being placed. Formwork comes in a variety of materials, shapes and sizes. Some common formwork material and shapes are available in custom made round fiberglass shapes, custom made sewn fabric form bags, standard steel or wooden panels.
