Installation

TICO Resilient Seatings can be installed in a variety of different ways depending on the requirements of the application.We recommend, where possible, bonding the resilient seating into position. The surface onto which it is to be bonded should be level, clean and reasonably flat. A suitable adhesive should be used- we recommend either Tiflex Contact S Adhesive or Tiflex Marine Epoxy Adhesive. The directions for use of such adhesives should be followed carefully. In all instances it is important that the seating is held firmly in place until the adhesive has cured and the full bond strength has been achieved. Resilient seatings are usually bonded to one surface only to hold them in place during construction of the remaining structure. However, different applications may require that both surfaces are bonded e.g. when a bearing is required to act in shear. Pre-cast beams or slabs can be placed directly onto the resilient seating material. Alternatively if joints or slabs are to be cast in-situ it is important to ensure that no concrete or other rigid material bridges the resilient layer. Such bridging would impair the movement of the joint possibly resulting in structural damage, and also severely reduce the vibration damping benefits by ‘short circuiting’ the pads. For cast in-situ work, suitable void filler or formwork should be used, e.g. TICO VF/PA Void Filler or permanent shuttering.When TICO VF/PA is to be used as permanent filler, it should be packed around the seating and all joints sealed with TICO A/ST Sealing Tape to prevent any ingress of wet concrete during the casting process. Alternatively, permanent shuttering in the form of marine ply or chipboard, or steel plate, may be laid on top of the bearing to create a void between bearings and prevent the ingress of concrete during casting, any such shuttering should be sufficiently rigid to ensure that the pads are not differentially compressed and overstressed. In some cases it is necessary to provide a positive fixing, for example by bolting through the pad. In these cases it is necessary to ensure that the bolt is also isolated from the surrounding structure. This will reduce the transmission of vibration from one side of the resilient seating to the other via the bolt itself. Bolt isolation is easily achieved by using TICO Resilient Washers (TICO S/WA and TICO MS/WA) and collars (TICO S/CO) as in the details below.
