Please enter your email address. In order to achieve these configurations, first the workers install the isolation and expansion joint filler material prior to concrete pouring (in most cases). A bond breaker tape is a tape which prevents the sealant from adhering to a surface. Bond breakers are usually designed for curing compounds to slab and precast members. During concrete construction, form oil, bond breaker, concrete splatter and other types of contaminants often contaminate reinforcement. TILT-CRETE is not recommended to be used on broomed or rough surface finishes. Provides both curing and bond breaking eliminates need for double inventory and handling. LEED INFORMATION Protects against water infiltration when properly sealed. The two main categories of bond breakers can be membrane formation and non-membrane formation. The material serves to prevent the concrete from bonding to the dowel bars, thus preserving the joint as a working one. Bond breakers prevent three-sided adhesion of the sealant (i.e. As the temperature drops, the concrete will contract. Wind loads which act on lifting a precast member, are an example of dynamic loads. To prevent that for precast slabs, membrane-forming bond breakers are applied so that it can hold up the water, necessary for the chemical reaction. Common uses: Glazing installations. TDS.

SELF-EXPANDING CORK EXPANSION JOINT is especially desirable where a constant friction-fit is required. Cement vs. DESCRIPTION Concrete and Chemicals. It preserves the characteristics of the concrete surface, allowing them to painted or modified using different architectural components, thus making the precast elects, visually appealing. Store in dry conditions, protected from direct sunlight. Flexible, lightweight, and can be formed around curved objects. Many a time, rods with a coating of certain chemical compounds, wife mesh, have been used as a bond breaker. PRECAUTIONS Membrane-forming bond breakers have the property to hold the water in the casting slab. Used for tilt-up, and precast construction projects. This guide will help you choose the best concrete . TILT-CRETE is used as a cure and bond-breaker in tilt-up, lift-slab, and precast concrete construction. They are not bond breakers. SDS. Site Map When bond breakers are applied to the concrete surface, it eventually joins together with the old concrete surface and once the concrete is poured, they become inseparable. This type of bond breaker will react with water and form a crude soap. Ensure base material is free of any foreign and loose materials and the base is cured prior to applying base bond breaker. See specification data and size information chart on page 2 for details. CERAMAR flexible foam expansion joint filler is composed of a unique blend of isomeric polymers in a very small, closed-cell structure.

Bond breaker tape is black polypropylene tape that provides an option to break the bond of the sealant between the joints between the surfaces of the concrete. Which can be cost-effective and time-saving for large structures. Bond breakers are applied to surfaces to which concrete is poured by the monolithic slab method. So that a joint can be provided in concrete. FIBRE EXPANSION JOINT is versatile, resilient, flexible, and non-extruding. It is quick and easy to install. A light hose down keeps it bright and clean. However, we can offer products to meet any specific specification. Static loads are which, whos value is constant, and the amount of the dynamic loads, continually changes. The coefficient of thermal expansion in concrete is 0.0000055 per linear inch of concrete per degree Fahrenheit of temperature change, yielding approximately .66 inch of movement per 100 feet with a 100 F (38 C) temperature range. If a bond breaker is not applied before the installation of a waterproofing membrane system, there are high chances that the membrane will wear and tear, forming holes, which would allow moisture into the substrate below, rendering the whole purpose of waterproofing system pointless. Easy-Lift FD is applied to the concrete casting slab to efficiently prevent the bonding of subsequent concrete pours. NOTE: The application of 1100 or VOCOMP series will interfere with the normal reaction of TILT-CRETE with the casting slab surface. Bonded concrete overlay (BCO) consists of a 2-in. This article can help you follow the good production and construction process. Concrete: Which Building Material is Better?
