Garage of an apartment, flooding.

Flooding of an apartment garage. Identified by Peter Weddell, owner/operator of Qld Home Buyers Inspection Service and Queensland Building Inspection Service, QBIS

Flooding of apartment garage

Inadequate drainage:

The sub-floor level of this unit building was below the ground levels on all four sides also below the flood level in the area, making it reliant upon an electric pump to remove excess water.

Garage flooding below an apartment

Blocked drain:

As you can see in this photo water below the grate had accumulated and was not draining away. The electric pump (below the water level) was not operating.

Be aware:

  • Electric pumps do not operate in a power outage.
  • Never relying upon an electric pump solely to remove excess water in adverse weather conditions.
  • Always have a backup drainage system (if possible) and/or generator.
  • Especially when soil levels are higher than the sub-floor level on all four sides of the building.

Finding your car submerged in water, before going to work is not a surprise you would want!

Flooding, seepage and drainage problems

Flooding evidence:

Evidence of debris that has accumulated to the lower block walls indicating recent flooding of water to lower section of the sub-floor garage areas.

More evidence of flooding from blocked and poor drainage.
