What Causes Internal Wet Area Damage?

There are many reasons as to why water could be penetrating a building causing internal water damage. However, majority of internal water damage is caused by:

Failed Waterproofing Membranes

Once a membrane fails, water will begin to seep in and cause damage.

Severe Weather

During severe heavy rains, water can often push through a building by sheer force.

Damaged Infrastructure

If a structure is damaged it can cause penetrable areas leading to internal water damage.
