How to avoid columns supporting a house from rusting prematurely.

Buildup of soil and gravel will cause premature rusting to columns and potentially compromise their strength.

  • This fault can usually be rectified by removing gravel and soil, wire brushing then applying anti-rust treatment.
  • Lowering of gravel an soil is required.
  • Periodic inspections need to be carried out for further rust.
  • If the columns have rusted significantly they are most likely to require replacing.

Significant rust can cause fracturing of the concrete footing that it is incorporated within. It would be costly to have the columns with their footings replaced. 

Important tips regarding column supports of buildings.

Although top of the footing should have extended by at least 100 mm above the soil level to comply with Building Code requirements.

  • Do not fit additional concrete to achieve the appropriate level. This will trap moisture and accelerate the rusting under the concrete and potentially cause cracking of the footing supporting it.
  • Make sure water does not pond around the column bases, this will accelerate rust.

If necessary: Create trenches aroung higher sides of the footing to allow water to flow around the column base.

Insufficient down-pipes and problems they are likely to cause.

  • Too many down-pipes connected to one storm-water pipe.
  • This will cause the roof gutters to overflow often and potentially cause rot to concealed timber.
  • Water may also enter interior of the house if the gutters overflow to their backside where the gutters have no eaves.

Rectification:

  • Fit larger gutters with more and/or larger downpipes would be required to help avoid this potential problem.
  • Bear in mind that more storm-water pipes may also need to be fitted to avoid overloading and backwash of water occuring.
  • Placing relief holes to front of the gutters, this will allow water to escape to front sides.
