The cost of form liner treatments are typically considered subsidiary to items 420 or 423 . The cost will vary depending on the amount of detail or size of the texture.
Form liners are available in three basic grades.
Single use form liners are made of rigid plastic and are used where reuse is not practical. Medium-reuse grade form liners are usually made from high impact plastic and are more economical than elastomeric form liners in situations where highly repetitive castings are not required. Heavy-reuse form liners are made from flexible elastomeric plastic. This built in resiliency results in the capability for greater re-use. When adding form liner treatments to a project, the designer should pay special attention to the segmental nature of building bridge and retaining wall structures.
