There is a certain indescribable excitement that comes with moving into a new home, or starting work at a newly refurbished office building. However, that excitement may quickly turn to dread with the discovery of rising damp in the building.

Perhaps you may have noticed certain stains on the walls that look like water stains, but you aren’t entirely sure if this means you have a damp proofing issue.

Here are 7 signs that indicate that you have a rising damp issue, and that you actually do need a damp proofing specialist .

It is important to note that there are various causes of dampness, but the most common is rising damp.

When moisture from the ground rises up a wall due to capillary action in the masonry material, it is known as “rising damp.” This moisture transmits corrosive salts and causes serious problems, which include the following signs:

  1. Stained walls
  2. Disintegrating mortar
  3. White salts residue
  4. Damaged, blistered wall paper
  5. Flaky and blistered paintwork
  6. Eroded brick and block work
  7. Damaged skirting, door and window frames (timber)

Depending on the level of damage, a cosmetic repair (mortar and/or paint) can serve as a short-term solution. However, when the situation is really terrible (usually in old buildings or buildings built in areas that have a very high water table), a cosmetic repair would be the wrong option. Corrective action is required at this stage in order to prevent further degradation of these areas. A damp proofing specialist will need to be called in.

This seminar will assist participants to better understand the mechanics, problems and avail solutions to extend service life of concrete and steel structures. Specifiers will be better equipped with the tools and knowledge to confidently provide de-signs and detailing where required. Contractors will equally be better prepared with installation methodology and options avail to meet specification.

HOST SPEAKER

The Webinars will be conducted by professionals with significant research and consulting experience, Dr. Ivan Razl, Ph., D., P.Eng, is the technical director of Gemite Products. Dr. Razl has extensive experience in research and development of specialty chemical systems, such as polymer and cement composite systems, concrete protection and restoration materials. He is a holder of a number of patents in Canada, USA and internationally. He has published various professional journals and presented a large number of scientific papers in his field.

AGENDA

The session will describe typical problems of concrete structures in waste water facilities, including sludge tanks, digesters, manholes and sewers, methods of re-pair, waterproofing and chemical protection.
