RISING DAMP

WHAT IS RISING DAMP?

Rising damp is a natural physical process caused by moisture in the ground soaking into walls. Water molecules have been shown to form dipoles (like magnets) that orient themselves to travel upward through the pores in walls.

A bit of science to understand the process of rising damp?

The water flowing in fault lines under a building create, through friction, an electric charge of between 50 and 500 millivolts. This capillary tension draws water up from the ground (+) into the walls (−).

Rising damp is characterized by the presence of mineral salts in the walls, such as nitrates (derived from animal wastes), and sulfates (from rock).

HOW TO DIAGNOSE RISING DAMP?

The visible signs of humidity issues

Visual diagnosis is the first essential step to determine the origin of damp. At a certain stage, damp is detectable or even visible. A tide mark (generally seen as a wavy line sometimes up to 1.4 m high), loose paint, peeling wallpaper, flaking walls, stains, whitish or grayish crusting on walls (saltpeter), mineral salt blooms, etc.

In older constructions, the absence of a damp-proof footing barrier (on top of a masonry bed supporting the rest of the construction) is sometimes the source of this type of problem.

Technical diagnostics

Analysis of mineral salts

Rising damp carries mineral salts such as sulfate and nitrate. For this reason, it is important to check for the presence of salts in the materials (using a salt detector).

Voltmeter

Through friction in the fault lines, water generates an electric charge that can be measured with a voltmeter.

Humidity meter

This measures the moisture present in materials.

Carbide meter

A carbide meter is indispensable to measure the water content in materials to obtain an accurate assessment.

WHY IS TREATING RISING DAMP VITALLY IMPORTANT?

Protect and maintain your property

Damp brings with it all sorts of damage to dwellings: mould, fungus, salt blooms, saltpeter, wood rot, unpleasant smells, etc. Damp eventually causes permanent harm to both the inside and outside walls of your building.

Avoid renovation work

The damage caused by damp in inside and outside walls will one day require the owner to carry out painting, plastering, and/or wall papering work.

Acting in good time allows significant savings to be made.

Make savings

Ambient humidity increases energy consumption and means higher heating costs. Humidity in the air absorbs heat and so more heating must be provided to offset this loss.

A damp house can consume up to 25% more energy than a dry house. Its market value soon falls and selling it becomes more complicated.

Protect your health and your children’s

In both children and adults, damp conditions can foster chronic illnesses and can cause various health disorders:

Allergies to mould and mites,

Respiratory illnesses, such as rhinitis, asthma, or bronchitis,

Joint problems, such as rheumatism and arthritis.

Children, who are naturally more susceptible, have between 1.5 and 3.5 times more risk of developing asthma or an allergy when living in a damp environment. In addition, an infant with asthma living in a damp environment is liable to develop a chronic cough.

WHAT ARE BFL’S SOLUTIONS?
