Planning and execution General information The most suitable joint tape must be specified on the basis of the anticipated loads. Ensure the tape is ■■ Joints should be as straight as possible, orderly and without elevation differences. ■■ Joint intersections should be at right angles where possible. ■■ Joint distance to grooves and edges ≥ 500 mm. ■■ Where possible, place construction joints in element zones subject to minor loads only. ■■ Concise drawings of the joint tapes, the joint profile, connections and crossovers. ■■ The original width of expansion joints is generally 20 mm. applied to...

Planning and execution Regulations DIN  18197 controls planning, design, handling, processing and installation of joint tapes corresponding to German standards DIN  7865 and DIN 18541. Additional regulations dealing with watertight structures can be found in the DAfStb guidelines Watertight Concrete Structures (Wasserundurchlässige Bauwerke aus Beton). Important notes Transportation The joint tape must be loaded carefully and unloaded and secured for transportation. It must be examined for damage and completeness on delivery. Storage in winter In winter the PVC-P joint tapes must be stored, where...

KUNEX® joint tapes in construction Construction, movement and dummy joints are primarily differentiated in concrete and reinforced concrete construction, depending on design and type. Construction joint Construction joints are planned if concreting on an element needs to be interrupted. The elements must be tightly connected. No movement is allowed between the different sections. Internal and external joint tapes are used to seal construction joints. If movement occurs, expansion joint tapes must be used. Expansion joint In this joint type the elements are separated by a running joint, i.e. the...

Construction joint tapes KUNEX® construction joint tapes for watertight structures KUNEX® internal or external, thermoplastic (PVC-P) construction joint tapes for sealing construction joints in concrete. Thanks to the fact that the tapes are installed with half the tape on either side and thanks to the configuration of the sealing anchors, a very good connection to the concrete is achieved, in addition to an increase in the area of the joint seal. The expansion element serves to flexibly connect the structural elements. Construction joint tapes are thermally spliced to be imper­ meable using a...

Star tubes KUNEX® star tubes for watertight structures KUNEX® thermoplastic (PVC-P) star tubes for sealing dummy and defined cracking joints in concrete. Star tubes consist of a soft PVC casing with four sealing anchors and two crack formation lips. The star tube is installed in a hard PVC inner sleeve to stabilise the casing. The two crack formation lips help to form an intentional, defined crack, which is then sealed by the four sealing anchors. ■■ Hard PVC inner sleeve for stabilisation ■■ General technical test certificate ■■ Star tube also available with eyes Application KUNEX® star tubes...
