New proposal for the treatment method of expansion joints in concrete waterproofing renovation work!
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 joints installed at 3-meter intervals 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. ○ The tape shape makes it easy to handle. ○ The self-adhesive layer on the back of the tape adheres to the substrate. ○ The incorporated plate-shaped metal pieces flatten the expansion joint. ○ It can be easily cut at any location where there are no metal pieces incorporated.
