Joints reconstruction via “Joist” method
Concrete flooring must be considered a semispherical surface because of the curling caused by humidity between intrados and extrados. That is why, in order to prevent chipping along the edges of the joints, it is of paramount importance to make resin joists after a minimum period of 40 to 50 days from the laying of the flooring.
