For hairline cracks (< 1 mm), injection is optional; the Atir strap alone may suffice.
When a beam has lost significant structural capacity, external strap reinforcement is often the most effective solution. This technique involves applying high-tensile-strength straps to the external faces of the beam to carry tensile loads. The two most common materials for this are and carbon fiber .

Several experimental studies report:
Sometimes "cracks" in a digital model are actually unconnected nodes. Geometry Check The two most common materials for this are and carbon fiber
