Rising Damp in your walls – What can you do?

What causes damp to rise in houses?

Causes of damp – rising dampness. Mostly found on the ground floor. This localized dampness at the bottom of your walls. This where the name “rising damp” comes from.
Moisture penetrates through or past the damp course. Resulting in formation of dampness.  Faulty or non-existent damp course, breakdown of damp course all can cause rising damp.
Moisture in structures occurs mostly occurs to brick and masonry structures soaking in and drawing upwards.Rising Damp in your walls - What can you do?, cementitious coatings against hydrostatic pressure,

Why Rising Damp is a Problem?

When water is wicked up in your walls.  The resulting damp not only affects the great appearance of a home.

Rising damp indicators:-

  • Paint bubbling or cracking.
  • Salts or efflorescence.
  • Mildew or mold on the walls.

Can occur on the outside as inside your house. If walls remain damp, over time, it impacts on the structural integrity of a house through rotting timber, degrading the structural integrity of masonry and brick. Damp areas may attract termites (I had this problem in a single brick or leaf wall in my garage). More effects caused by the increased moisture in the walls can cause rusting of any reinforcement steel, create condensation, can damage furniture and soft furnishings, and even cause health problems to residents.

Prevention & treatment.

What can you do to stop moisture rising in your building?

Modern waterproofing methods helps prevent damp rising up your walls. The proper treatment prevents the problem from reoccurring.

  1. Correct installation of damp course – often damp course is ineffective as it finishes within the mortar line. And water enters below the damp course.
  2. Rendered walls allow water to wick up the wall. Stopped by the installation of a Waterproof barrier.
  3.  Repairing the damp-proof course, usually means removing a brick course and reinstalling the damp course correctly. Make any joins, created in this process, watertight.
  4. Mortar from the brick or block mortar lines may be filling the cavity to prevent water from draining from weep holes.
  5. Clear weep holes from mortar debris.
  6.  Drill couple holes into each brick just around the floor level and pump in a silicon-based waterproofing mixture under high pressure. Forming a waterproof barrier preventing the water from wicking up the wall bricks.
  7.  Using cementitious waterproof membranes such as Drizoro Maxseal Foundation

Rising Damp (structural)- Wikipedia
Jump to Rising damp. Historical context. Rising damp is usually referred to in Victorian times as a damp-proof course (a physical barrier) in walls which prevent dampness rising up the wall. ‎

Structural dampness is the presence of unwanted moisture in the structure of a building, either the result of intrusion from outside or condensation from within the structure.

A high proportion of damp problems in buildings are caused by ambient climate conditions. Such as dependent factors of condensation and rain penetration. Capillary penetration of fluid from the ground up through concrete or masonry is known as Rising Damp and is governed by the shape and porosity of the construction materials through which this evaporation limited capillary penetration takes place.

Structural damp:-
Regardless of the cause or pathway through which it takes place. Rising damp is always exacerbated by higher levels of humidity.
