Showing results 1-7 of 7
Concrete blockwork – efflorescence
-
Moisture in the blocks causing salts to migrate to the surface leaving a whitish-grey residue
Concrete blockwork – cracks in the mortar and/or blocks
-
No control joints incorporated in wall
-
Differential settlement of the building caused by swelling/shrinking of clay soils and inadequate foundations and indicated by cracking through the mortar stepped across the face of the wall
-
Building subjected to vibration movement such as earthquake, high wind
-
Wall unreinforced
Concrete blockwork – peeling or flaking of paint
