INDUSTRY WATCH - PRECAST CONCRETE

This product and system is an ode from one Indian Precaster to
the other precasters who are facing issues in terms of cost overruns
or time overruns like we were, way back in 2016 or for those who
desperately seek an alternative to the CIS joints in Precast Projects GUEST ARTICLE
who often induce risks
The product is carefully designed by feedback from our own
production and installation engineers and under guidance of able
product designers and consultants from all over the world. After
nurturing and developing the idea for almost 7 years in our own
projects, we feel that we are ready to share this with other fellow
Indian precasters at very economical rates

Applications already performed in Precast India
1. Shear wall to shear wall connection
2. Retaining wall to retaining wall connection
3. Rebar continuity in beams to avoid in-situ junction by casting
column upto beam top instead of beam bottom
