Three precision epoxy grouts: E3-Deep Pour, E3-Xtreme and E3-Flowable will be demonstrated. These products are precision grouts used to support equipment and machinery in demanding environments. The demonstration will explain why and where epoxy grouts are used, how they are tested, project preparation, mixing and application, and other considerations. The features and benefits of each product will be described, and newly patented dust-limiting aggregate technology will be introduced.
Demonstration will show what an acceptable CMU substrate for application of air barrier materials looks like, how to prepare Sprayable Cat 5 air barrier coating for application, discuss proper pump specifications for spraying the material, and demonstrate best practices for spraying Sprayable Cat 5, a Silyl-Terminated Polymer air barrier to a CMU substrate, while providing “tips & tricks” along the way.
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 Ituango dam is an embankment dam that is currently under construction on the Cauca River in Colombia. The largest hydroelectric power plant in Colombia’s history. Three large diversion tunnels used to divert the water from the river around the construction site during construction collapsed as a result of heavy rainfalls. The nearly completed pump house had to be flooded to accommodate premature water build-up in the reservoir. These tunnels would need to be permanently sealed. “Pre-stoppers” would need to be constructed in place to serve as bulk heads between which would ultimately be excavated and back-filled with concrete to permanently seal the tunnels. Additional to standard anti-washout properties, the grout had to withstand swiftly flowing water and exhibit an extended working time at temperatures above 32 degrees C. A custom grout was developed for this application. In the end, hundreds of grout micropiles were tremied, consuming more than 1,650 tons of grout, to produce...
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.
In new construction, cracks can appear for variety of reasons: curing, temperature deviation, pressure from adjacent conditions, or settlement. This presentation will outline various types of cracking, how to plan to avoid them, and how to address them after concrete has been placed.
Due to improper design or implementation sometimes Part of the New projects are re-executed or repaired. Islamabad - Rawalpindi BRTS (Bus Rapid transit System) Consisted of 20 Stations Covering around 23 km path connecting twin cities. Each station Roof Consisted of ACP Sheets Fixed on Aluminum Frame with Steel supports. The joints of ACP sheets were filled by Silicon but improper materiel and workmanship caused leakage in joints. Total length of joints was over 400,000 RFT. Leakage was invariably from almost every area.
