Clarifier Tank – Expansion Joints

Categories: Concrete Repair

Concrete clarifier tanks may often have joints and seams that require flexible filling such as expansion joints.

As concrete tends to expand and contract dependent on temperature, the structural elements can shift slightly. Expansion joints are used on multiple face concrete surfaces to enable this movement without damage or stress to the overall concrete substrate.
