MIBO WS – WSB -WSE -WSBIQ – WSBE
Profiles based on thermoplastic vinyl resins of the highest quality, with high resistance to aging, to the aggressive action of alkaline acid substances and to mechanical stress. They are used, depending on their cross-section and shape, in expansion joints, in construction joints and in any type of structure (civil, industrial, etc.), in order to give the latter a perfect hydraulic seal.
Any building work requires appropriate structural breaks to allow free movement caused by settling, thermal expansion of materials, deformation under load. A structural joint has the twofold task of absorbing such movements at predetermined points of the structure, without causing cracks and fissures in adjacent areas, and of waterproofing the interstice from the ingress of water, air and foreign bodies. Structures in contact with water or moisture must be designed and built with great care, so that the joints are watertight.
ADVANTAGES
– The specifications of these profiles are long lasting and remain unaltered even at low temperatures;
– They do not require special warehousing or conditions;
– They can be supplied in various degrees of hardness and dimensions according to their destined use;
– Contrary to other neoprene or rubber profiles they can be easily welded one to another. The welding either with hot air or heated blades can be carried out on site;
– They are suitable for sea water contact
– They comply with the regulations ASTM D. 412-75 and ASTM D. 746-747-2240 and the relating ISO
APPLICATION
The inner profiles (WS-WSB-WSBIQ) must drawn in the concrete and have to be secured to the framework to ensure a certain stability during casting and to avoid the formation of folds. The outer profiles (WSE-WSBE) must be secured directly on the formworks or on the foundations, with the anchoring blades pointed towards the casting. The profiles can be welded directly on site with an electric hot air welding machine. It is advised to have care to vibrate the casting near the joint, in order to avoid the creation of the so called gravel nests.
MIBO WS-WSE profile are used for cold joints where the concrete has been cast at different times and there are iron rods passing through one casting and another. MIBO WSB-WSBIQ WSBE profiles are used instead for expansion joints, where concrete castings cast at different times feature a cavity equal to the width of the bulb and the cavity must be filled with a suitable elastic material. In this case there are not iron rods passing through one casting and another.

ACCESSORIES FOR WELDING
The electric hot air blow pipe are used to make special “L”, “T” or cross couplings.
