Waterstops profiles

MIBO WSBE

The profiles MIBOWS-WSE-WSB-WSBIQ-WSBE are produced with thermal plastic vinyl resins of exceedingly high quality. These materials confer to the profiles a high resistance to aging, to the aggressive action of alkaline/ acid substances and to the mechanical stimuli. They are employed, depending on the sections and the shape, in dilation joints, in casting and construction joints and in any type of structure (civil, industrial, etc.), in order to give to the latter a perfect hydraulic seal.

Profile for inner and outer structural/expansion/dilation joints
Any construction requires opportune structural intervals to allow for movement caused by ground settling, the thermal expansion of materials and deformation under load. A structural joint has the dual task of absorbing this movement in predetermined points of the structure to avoid the formation of cracks or fissures in adjacent areas and also acts as a barrier to ensure water, air and foreign bodies do not penetrate the interstice.
Structures in contact with water or dampness must be designed and constructed with the utmost care to ensure the joints are watertight. The MIBO WSB-WSBIQ-WSBE waterstops, made of PVC, with central ringshaped bulb are the perfect solution for a perfectly watertight seal.
READREADADVANTAGES
  • 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

READREADAPPLICATION
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.
