This demonstration shows Sika's new one coat traffic coating systems. Sikalastic®-720 One Shot is a two-component, integral texture, fast-curing, aliphatic, elastomeric polyurethane waterproofing coating intended for vehicular and pedestrian traffic. Applied in a single step, Sikalastic®-720 One Shot replaces the need for a base coat and multiple topcoats. Sikalastic®-726 Balcony One Shot is a two-component, aliphatic, elastomeric polyurethane traffic coating system that has both superior flexibility and abrasion resistance. Easily applied in a single coat, with or without primer, and designed for pedestrian traffic, specifically balcony and pedestrian applications.
Proper installation of the RFP and Mesh system on stucco substrates that have cracking issues will be demonstrated. This involves application of the product with embedded mesh. Also shown will be the application of a "Kiss Coat" of material applied over the previous first coat installation. Finally, how to perform a field adhesion test to ensure adequate bond will be demonstrated. The product, history, benefits and procedures for a successful application and installation will be discussed as well as proper surface preparation and how weather conditions can affect the installation. Demonstration will be hands-on installation on an actual building.
The demonstration will cover the use of MAPEI’s high alkaline corrosion inhibitor, Mapefer 1K and encapsulation of the repair area with Planitop 12 SR. Planitop 12 SR is a versatile, sulfate resistant, fiber-reinforced, with silica fume and corrosion inhibitor that can be applied by hand, pump, or spray on horizontal and vertical surfaces. Demonstration will show how to utilize these products in accordance with ACI Repair Application Procedures (RAP) 3, 6, and 7 as well as ICRI Guideline Nos. 310.1R and 310.2R. Demonstration will showcase a project where Planitop 12 SR was recently used to repair a Wastewater Treatment Tank.
Selection of the most appropriate, professional tools for the setting of foam backer rod at the correct, consistent depth, without puncturing the skin, is the first step in creating a sealant joint that is long lasting and meets sealant manufacturer specifications. Next is the selection of the optimal sealant dispenser and nozzle. The size and orientation of the joint and the viscosity of the specified sealant will guide an installer to the most efficient drive, material containment unit (MCU) and nozzle for the application. Lastly, the selection of the most appropriate caulk finishing spatula and the technique employed are critical for the sealant to adhere and perform to specification.
EDCC is an extremely novel and first of its kind application for use primarily in the seismic retrofit of unreinforced masonry walls. This spray-on technology incorporates a highly sustainable and cost-effective mixture of recycled admixtures that have proven to be extremely effective at greatly enhancing the ductility and strength of unreinforced structures. Its ease of placement and unique flexural advantages make it very unique in the field of seismic upgrade with the potential for additional applications with other infrastructure improvements.
Construction errors such as the misplacement of reinforcing steel and modifications like the addition of openings traditionally required intrusive repair methods. The addition of structural steel support or enlargement of the concrete elements is often not aesthetically pleasing or practical and the cost and time impacts are onerous. FRP strengthening solutions are non-intrusive, practical, and can be implemented quickly without major impact on the other building trades. The presentation will guide the audience through the feasibility assessment of FRP strengthening and implementation of the strengthening solution. The roles of the various parties, including the Engineer of Record, the FRP Design Engineer, the General Contractor, the Structural Contractor, and the FRP Installer, will be illustrated. Photographs of completed repairs will be presented.
The recommended application methods utilized to successfully install Pecora Deck HB1000, a two-part polyurethane traffic coating, will be demonstrated. Demonstration and discussion will include primers, waterproofing base coats, and high-build, UV resistant topcoat.
The installation of externally applied FRP systems has been slow to evolve due to limitations of materials used in the field. This demonstration will show how to make the most out of the materials with efficient application methods that will save time and money.
The demonstration will show the ins and outs of Sika's FRP installation process with the multiple system options Sika offers to help with your needs for a proper install on site.
Post-tensioned concrete is a strong and durable material for construction of exposed parking structures. These types of structures are also fire resistant, but they can be damaged depending upon the severity of the fire. The structure in this presentation suffered significant fire damage early in its construction. The presentation will cover the discovery and testing methods used to determine the extent of fire damage, and the design of the repairs that were instituted to restore strength and allow construction to continue.
