The problem here was with the pooling of water on the paving and the level of the paving being close to or at the floor level of the bathroom. In addition, it appeared the bath waste or water supply may be leaking.

How to monitor cracks in your walls and floors!

Often, home buyers and homeowners are worried by cracks in the house and boundary walls, especially plastered walls!

The good news is that, generally, concrete, stone, brick and masonry walls and concrete or screeded floors that have cracks less than 1 mm wide (the thickness of a credit card) are common and usually do not warrant any corrective action. Most of these small tight cracks are caused by normal shrinkage as the moisture in the walls and floors evaporates over time or settlement of the structure which usually occurs within the first few years after construction.

Be warned, however, that changes in condition around the structure may also cause settlement many years later! Examples are planting a new garden or tree or removing a garden or tree that is against or close to the house.

Crack Fillers

Note that all cracks should be sealed with paint, caulk (sealer) or mortar to prevent water from getting into the structure.

Moreover, if a horizontal, vertical, or diagonal masonry crack is filled with hard masonry patching compound, any substantial future movement is likely to show up as a new crack in the patched area or nearby.  Therefore, always use a non-shrinking grout to prevent stressing yourself!

Continued movement

Cracks that continue to move are a reason for concern! Continued movement in cracks should be evaluated as there may be a need for corrective action. Therefore, if you notice a crack has re-cracked or the crack has opened or gotten larger it should be monitored! However, first, make sure there is no shrinkage of the filler product.  All cracks that are 5 mm and greater should be carefully monitored to ensure there is no continued movement.
