Concrete Placement

Concrete Placement

Concrete placement for the repair of lock walls is pumped or poured into forms. This may be done with flexible piping. The heights of walls vary. Some full-face pours may have a height of 50 feet. General procedure is to pour concrete on alternating monoliths. Concrete forms are normally removed anywhere from 1 to 3 days after concrete is placed. Membrane curing compounds are often applied to formed concrete surfaces.

Cracking is a persistent problem with repair concrete on lock walls. Cracking of thin layers of repair concrete can result from shrinkage, thermal gradients, or autogenously volume changes.
