This type of bond breaker holds water into the casting slab. P10-2605. DECK-O-JOINT resists acids, alkali, chlorine, etc. First Bond Breaker Coat Application Apply TILT-CRETE to the point of rejection on the casting slab just prior to the placement of reinforcing steel. CORK EXPANSION JOINT and SELF-EXPANDING CORK EXPANSION JOINT are used where high resiliency is needed, such as in sewage plants, floodwalls, spillways, filtration plants, and numerous commercial and industrial applications. SPONGE RUBBER EXPANSION JOINT is produced to a uniform thickness and density from gray-colored, top-quality, blown sponge rubber. Contact Us The top of SNAP-CAP pulls free and can be discarded. a water repellent, wax based bond breaker material. DECK-O-JOINTs exclusive channel design prevents excessive seepage and water damage. The tape shall be compatible with the sealant. The bond breaker shall be applied at the manufacturing facility. They are also applied on concrete surfaces to reduce the cracking of slabs caused due to temperature and moisture fluctuations. We use cookies to improve the functionality and performance of this site. To prevent the sealant from adhering to the surfaces, bond breaker tape is applied along the whole width/length of the base of the joint. Bond breaker tape stops the sealant from adhering to the surfaces and prevents the three-sided adhesion. Excellent stability; does not require continuous mixing throughout the application; the material must be mixed only prior to application. Using a bond breaker can extend the life of the formwork. PDF TECHNICAL DATA SHEET Sec SECTION 2 - Dayton Superior Protects against water infiltration when properly sealed. If less than the recommended amount is applied, the film may not be continuous or of sufficient thickness to inhibit inter-slab moisture penetration which may result in panels sticking to the casting slab. These bond breakers have the property to hold the water in the casting slab. Save my name, email, and website in this browser for the next time I comment. This product is then unloaded on the site. PDF Section 461 Sealing Roadway and Bridge Joints and Cracks Please see our Privacy Policy for details. Bond Breaker Geotextile - US Fabrics TILT-CRETE is low-VOC formulation that does not contain wax or hydro-carbon resins. When placing geotextile in this condition, geotextile needs to properly bond to adhesive before construction or vehicle trafficking begins. Wherever, CERAMAR is a flexible foam expansion joint filler composed of a unique synthetic foam of isomeric polymers in a very, SPONGE RUBBER EXPANSION JOINT is produced to a uniform thickness and density from gray-colored, top-quality, blown sponge rubber. It avoids compression cracks on tilt-up walls. {{ selectedBranch.City }}, {{ selectedBranch.State }} {{ selectedBranch.PostalCode }}, There are no results matching your search terms, {{ product.defaultVariant.mapPrice.formatted }}, {{ product.defaultVariant.finalPrice.formatted }}, {{deps.UserLocation.selectedBranch.City}}, {{deps.UserLocation.defaultLocation.City}}. Get Traffic & Exposure. Bond breaker tape is easily available in widths like 15mm, 20mm, 25mm, 50mm etc. Join now! Share it with your friends! Rods are fixed between two adjacent surfaces of concrete. The strength development of this concrete type must be hence factored in the project sequencing process. Pavement Plans and Specifications | Caltrans - California Department of Bond breaker tapes are used for isolating sealant and eliminating sealant adhesion to concrete and metal. 7.1 Introduction. RepCon 928 FS. Apply backup rod and bond breaker tape in expansion joints. This is done to prevent its surface from sticking or bonding together. Embedded waterstops for cast-in-place concrete. In fact, some types of joint fillers can serve as a backing material and bond breaker, in which the applicator can apply the sealant directly on the filler. Not very much in use. Common uses: Glazing installations. A non-reactive bond breaker interacts with the concrete surface to create a waterproof surface. {"@context":"https://schema.org","@type":"FAQPage","mainEntity":[{"@type":"Question","name":"Bond Breaker Tape","acceptedAnswer":{"@type":"Answer","text":"Most tapes used as 'bond breakers' are made of polymer films such as PTFE and polyethylene.
