700 series dee adjustable seawall form.

dee has been an innovator in the manufacture of steel precast concrete seawall forms. Our standard adjustable seawall forms are 5' to 6' wide and 6" thick and use a sliding bulkhead to produce panels 10' to 16' high in 2' foot increments. dee's custom seawall forms can be made to be able to form seawall panels up to a height of 20'. The tongue and groove design forms a seawall composed of interlocking panels.

dee seawall forms are manufactured with alternating male and female keyway ends so panels fit perfectly. Our seawall forms use quick acting slotted connector bolts and wedges to quickly and firmly lock the seawall forming components together.



dee seawall forms are designed to provide custom and adjustable height (10' to 16') concrete forming of seawalls used in ports, canals, channels, water treatment plants, dammed areas, boat docking areas, flood control projects, shoreline erosion projects, retention ponds, fish farms and other aquaculture operations, and other similar applications.


Specifications and ranges of sizes

dee adjustable seawall forms are made out of 10-gauge steel, and can be used to form panels in thickness from 4"-12". They have the capability to form panel heights of 10', 12', 14' and 16' with form widths up to 10'. Seawall form sets consist of a male keyway form, a female keyway form, a fixed bottom bulkhead and top adjustable bulkhead.

Custom seawall forms with fixed bulkheads are also available upon request and are available in heights up to 20' and widths up to 10' depending on your finished seawall panel requirements.

dee's seawall forms have been designed with slots for lifting elements built right into the fixed bottom bulkhead. They can be assembled and disassembled using fast acting "thread less" connector bolts.
