Damp Proofing or Water Proofing?

Damp Proofing:

Where the external ground levels are lower than internal floor level then a damp proofing system is required.

Rising damp is where a failure of an in-efficient damp proof course has been installed or damp bridging due to the raising of external ground levels eg paths or driveways. In older buildings, where there is the absence of a damp proof course or leaking downpipes rainwater gutters.

These can lead to signs of dampness internally

  • Peeling Paint and Wallpaper
  • Damp Musty Odour
  • Decayed Skirting Boards
  • Stained and Crumbling Plaster Work
  • Salt Deposits on the Wall
  • A discoloured white tide mark indicating signs of rising damp

Solution: Heyen Rising Stop Injection Cream combined with re-plastering of the internal walls to avoid the effects of future spoiling.

 

Water Proofing:

If the external ground levels are higher than the internal walls for example an underground structure eg: a basement then a full waterproofing system is required.

Penetrating damp, is where moisture ingress penetrates horizontally through the wall fabric of the building. Even if the dampness hasn't penetrated all the way through, this can still lead to various other damp issues in the property.

  • Damp and Damaged Plaster work
  • Dry Rot/Wet Rot and Fungal Spores on Timber
  • Damp Musty Odour
  • Black Mould Growth
  • Watermark Damage to the Internal and External of the property

Solution: Heyen Tanking System.

 

Caution:

If a damp proofing system is used where a water proofing system is required, this could have serious effects and the high probability of water ingress and flooding.

As well as saturated water in the ground the potential sources of water ingress are as follows:

  • Burst Water mains
  • fluctuating water tables
  • the future effects of climate change
  • temporary pockets of water
  • perched water tables

Different causes of dampness require different systems of treatment so it is very important to identify the correct diagnosis.
