New proposal for the treatment method of expansion joints in waterproofing renovation work for restrained concrete!
The Joint Keeper was developed to solve the problems of traditional joint treatment methods. The concrete substrate can rise above 60°C due to summer sunlight and drop to around -20°C due to radiative cooling in winter. This temperature difference (80°C) causes the expansion joint width, installed at a 3m pitch, to widen and compress by an average of about 2.5mm. 【Features】 ○ Simply remove the cap from the existing expansion joint, apply primer, and stick the Joint Keeper to complete the joint treatment. ○ Easy to handle due to its tape shape. ○ Adheres to the substrate with the self-adhesive layer on the back of the tape. ○ Flattens the expansion joint with the incorporated flat metal pieces in the tape. ○ Can be easily cut at any location where metal pieces are not incorporated.
