This technique worked on development of technology to prevent the cracking occurs also in refurbishment layer of cracking the top by aging, in the case of adopting the pin net method on the outer wall that occurred through cracks. By typing an anchor pin in through cracks part, it was tried to reduce the cracking of the repair layer because of controlling the crack behavior of concrete. Experiment was performed from strength and energy absorption of the specification by the bending test of a small specimen. As a result, to type the T-forked anchor pin into the through cracks section revealed that can be expected to improve the adhesive strength at the crack and the flexibility to warping of the wall.
