How do you stop cracks in walls from reappearing?
This can be achieved by fixing a new plasterboard layer over the affected area, making sure that the new lining is adhered to one side of the open crack only.

What kind of foundation cracks are bad?
Of all the foundation cracks, the stair-step cracks are the most dangerous. They normally run in a diagonal line and assail concrete blocks and brick foundations.
