Crack Repair

Structural Crack Repair Specialists

Most buildings develop cracks in their fabric at some time. Diagnosis of the specific causes of crack formation is important to determine their effect on the performance of the building and whether the movement is complete, incomplete or seasonal.

Cracking within components involves the strength of the material. When building components are restrained, their strength is exceeded by stresses arising from movement in the materials therefore cracking results.

The degree of cracking is dependent on several factors including the materials used in the construction and the cause of the cracking.
