Expansion Join of structure joint portion does induced drain leaked water with insertion of expansion joint subsidiary which is manufactured to make possible induced drain
on 4 sections of overall structure, between structures which is joint portion of concrete structure after construction of concrete structure conncetion.
- Manufactured in soft PVC, accept smoothly contraction and expansion according to atmosphere temperature change, prevent deteriation and breakdown through perfect adhesion with structure
- Shut off earthy material which is inflowed to internal with adhesion of each end portion of drain bar onto structure internal section, possible induced drain of percolating
water which is percolated in case of raining, and underground weater leakage in case of public usage
- Enhance problems of untreatment for percolating and underground leakage water.
Problems of Urgent Structure Expansion Joint
When it is finished at side portion and roof connection portion of concrete structure with sealant calking, it occurs oxidation and corrosion at portion which is exposed to
ultraviolet ray, and water leakage occurs between concrete structures with percolating of rain water, underground water and plant root through earthy material surrounding
sturucture by dropped out calking.
Complementary Countermeasure of Convetional Structure Expansion Joint
It is blocked from percolation of rain water, underground water and plant root to inner section of structure at structure joint portion through adhesion of drain bar section
which is manufactured to make possble induced drain on oveall 4 sections of structure, even though there is water leakage, it is possble induced drain to make passing way at
Drain Bar Insertion (New Installation)
Drain Bar Insertion (Repart Installation)
Afer Drain Bar Construction (New Installation)
Afer Drain Bar Construction (Repair Installation)
- Easy to drain influent water which is inflowed anlong with Slab
- No corrosion at all by Oxygen, Ozon, Untravilolet ray
- Able to use semipermanently
- Easy to install, generate reduction of human resource, time and construction period.
