ALADIN (formerly known as Jeene Joint)

Transcription

1 Structural Sealing Expansion Joint System DESCRIPTION ALADIN is a structural sealing joint system comprised of a neoprene profile, which is air-pressurized and bonded in place with a specially formulated epoxy adhesive. When properly installed, the high performance ALADIN joint system will not tear away, protrude out of, or slip from its original position when exposed to repeated mechanical or thermal movements. Complete adhesion of the epoxy to the profile and joint wall is achieved due to the air inflation during installation. ALADIN is the most durable, versatile, cost-effective, and watertight expansion joint in the industry. Two different types of ALADIN neoprene profile are available and each is available in a range of sizes to meet particular project requirements: W-type profiles with 100% movement capability are used for dynamic movement, for example for bridges, viaducts, tunnels, car park structures and water management applications. FW-type profiles are used for movement applications that require a flush-to-finish system, for example pedestrian traffic areas, industrial buildings, airport terminals and car park structures, but are also suitable for most W-type profile applications. RECOMMENDED FOR Sealing joints in elevated highways, stadiums, tunnels, and other engineered structures. Expansion joints requiring multidirectional movement of the structure without joint system failure. Linear, angular, or circular expansion joint applications. Parking Structures requiring a watertight system. FEATURES AND BENEFITS Rapid installation Designed to facilitate rapid return to service by means of pressurization. By minimizing downtime and improving productivity, structure can be fully operational in record time. Unique Design Engineered from durable neoprene material, ALADIN profiles have outstanding resistance to degradation from ozone, weathering, oils, and most other chemicals. The sidewall ribbing maximizes the available epoxy adhesive surface bond area. A two-component, solventless, non-sag epoxy adhesive is provided to ensure a tenacious bond between the profile and concrete, steel, or Wabo Crete II. Inflation during installation ensures a completely watertight bonded system. Neoprene Seal Wabo Adhesive Versatility The W profile design provides+/-50% movement, while also allowing for multi-directional movement. The FW profile is ADA compliant and provides +/- 35% movement. ALADIN will conform to vertical and horizontal directional changes, T-intersections, and varied gap dimensions. Fabricated on site to suit site conditions. Bonds directly to concrete or steel if required. Differential, rotational and shear movement accommodated. ALADIN W Profile ALADIN FW Profile Page 1 of 5

The concrete sidewalls must be sound and free of all contaminants such as grease, oil, form release agents, ets., prior to installation of the ALADIN. The preferred method of surface preparation to produce laitence-free, roughened sidewalls is where abrasive blasting. When blasting is not permitted, disc grinding should be employed. Care should be taken to insure a coarse disc is used; so as to produce an abraded surface. The gap openings should be blown out with clean air to remove dust. Installation must be performed in joint gap openings with sound, clean and dry substrates. Any loose portion of concrete at the gap must be removed and the concrete properly repaired as directed by the engineer.

This is a requirement in new or existing construction. All oxidation must be removed and white steel revealed. Where abrasive blasting is not permitted, steel surfaces will be aggressively disc ground to roughen and abrade the surface to achieve the white steel condition. Stainless steel surfaces require aggressive grinding and blasting to remove the smooth, glassy surface for acceptable installations. On galvanized steel surfaces, the galvanizing material must be removed to look like white steel. Immediately install the ALADIN Profile into the steel joint gap to avoid oxidation of the steel surface. Forming materials should be carefully removed to avoid edge spalling of the concrete. Joint gap edges should be chamfered to help prevent small fractures and spalling. Edge spalling conditions should be repaired and allowed to properly cure prior to installation of the ALADIN. Installation Prepare concrete surface as per ALADIN installation guide. Sidewalls of actual joint and ribbed area of ALADIN seal are coated with Wabo adhesive. ALADIN seal is then placed into the joint gap, aligned and inflated with air. Air is released from profile after the 24 hour Wabo Adhesive cure period. Limitations Profile installation in warm temperatures requires a deflation technique. Joint gap openings must be consistent. Oversized profiles may be required where installation temperature is significantly below the median. Follow Wabo Adhesive requirements. Protect from construction activities. ALADIN neoprene profiles are supplied in lengths to suit project requirements and can be supplied in continuous lengths up to 150 m. Wabo Adhesive is available in standard or cold weather grades and is supplied pre-packed in plastic containers as a complete unit. The cold weather grade comprises 0.9 kg of Part 1(adhesive base) and 0.9 kg of Part 2 (activator); the standard grade comprises 0.9 kg of Part 1 (adhesive base) and 0.45 kg of Part 2 (activator). Wabo profile glue is supplied in 20 g. plastic tubes. Wabo conditioning agent is supplied in 0.95 liter plastic containers. Wabo concrete cleaner is supplied in 0.95 liter tins. Page 2 of 5

3 APPLICATION: 1. REPLACEMENT OF EXISTING JOINT APPLICATION: 2. MULTI-PURPOSE WATER TIGHT JOINT For Structural Gap of 100 mm: For Structural Gap of 150 mm: STOAGE ALADIN can be used, in combination with WabocreteII, to replace / refurbish old joints on bridges and highways. The work involves removing the existing damaged joint by saw cutting concrete behind the joint. Specially fabricated steel sections are then installed on the structures using Chemical Anchors. The newly created block out is filled with WabocreteII and Aladin is installed near the road surface. Benefits: Fast turn around time. Traffic can start within 5 hours. Economical and Durable Solution for replacement of existing joint. 100 % Watertight Joint Proven system PRECAUTIONS STORAGE ALADIN neoprene profiles should be stored by coiling without kinking or laid in lengths without deformation. They should be kept free from contamination prior to installation as contamination may impair the performance of contact products such as Wabo adhesive and profile glue. Wabo adhesive, profile glue and conditioning agents should be stored under cover, protected from direct sunlight and clear of the ground. Storage conditions should be dry, above 5 C and below 28 C. Under normal storage conditions the shelf life of Wabo adhesive, profile glue and conditioning agents in unopened containers is 12 months. Page 3 of 5
