Flat pillar and shaft blocks

Blocks for lost shells and bracings

 

The KLB flat pillar and shaft blocks serve as lost shell for statically required, weakly reinforced concrete for bracing corner areas in the basement or the masonry of houses being raised between longer walls or as and end (jamb) for larger openings.

 

The blocks guarantee secure concrete work and allow a uniform plaster base. They can be insulated at the construction site to improve thermal protection.
