Vertical Joint Concrete PSB K30 – pumpable dry concrete for precast elements

Vertical joint concrete PSB K30 is a CE-marked, ready-to-use dry concrete classified as C 25/30, designed for jointing concrete elements — both vertically and horizontally. Thanks to its optimized composition, the mix is pumpable and non-slumping, allowing joints and seams to be filled without additional sealing measures or vibration.

With a maximum grain size of 4 mm, a fine and dense result is achieved even in narrow joints or seams. The vertical joint concrete works excellently for overlays, element joints, repairs, and post-castings — ideal for constructions where good joint sealing and durability are required.

Delivered in 1000 kg bags, suited for larger construction and assembly projects — from element and modular buildings to repairs and castings after installation.
