ER‑7 exhibited minimal mass gain and only modest reductions in dynamic modulus, indicating superior resistance to moisture‑induced micro‑cracking. eptar reinforcement 7 crack
The findings support the adoption of ER‑7 as a versatile, high‑performance crack‑reinforcement technology for both new construction and retrofit applications. eptar reinforcement 7 crack
