Owners of commercial buildings who lease out their property to other
businesses have a responsibility to ensure that it is correctly waterproofed. Statistics

Why you need waterproofing for
your commercial premises:
Preventing loss of rent
Buildings with water leakage and seepage problems can soon become uninhabitable.
To avoid loss of rental income in the future, owners should have their
properties waterproofed properly from the start.
Water leaks are dangerous, especially when electrical wiring is exposed
to water leaking through the structure due to insufficient waterproofing. Such
situations can lead to fire or electrocution, making the building owner liable
for any damage or injury suffered by the tenants.
Water leaks caused by inadequate waterproofing can cause timber to rot, metal
to rust and lead to a form of degradation known as concrete cancer. A building
that is structurally unsound due to the long-term effects of water damage can
be a major disaster waiting to happen.
Keeping it healthy
Mould and mildew caused by water penetration can trigger allergic
reactions and respiratory problems in the building’s occupants, leading to
long-term illness. Bacteria can also thrive in damp areas, and could result in
the building being labelled ‘sick’, making it difficult to lease.
Damp buildings create a suitable environment for termites, cockroaches,
rats, mice and other pests, not only posing a health risk for occupants but also
creating an ongoing and unnecessary expense for the owner on pest control and
