Bulkheads

Our patented floating bulkhead system can be configured to fit several types of spillway bay sizes and pier nose shapes. We also have several types and sizes of box type cofferdams that can be temporarily set and dewatered to allow access to gate structures.

Intakes and Headworks
Bothma can also implement construction and replacement of structural steel components.
We often work closely with both dam owners and engineers to develop feasible construction processes and cost analyses on difficult rehabilitations and installations.
