Rising Damp vs. Condensation

One of the fundamental points of confusion on the subject of dampness is the confusion between rising damp and condensation. Recent research on condensation has finally clarified the differences between these two phenomena.Rising Damp vs. Condensation – Simple, Non-Technical ExplanationRising…

Breathability Banner

Breathability

The concept of breathability is paramount in building conservation. Breathability means the fabric of old building needs to be open-pore or permeable to moisture. This way water vapors can penetrate the fabric and moisture can evaporate out from the fabric…

Moisture Sources in Old Buildings

The topic of moisture sources in old buildings can be easiest understood by inspecting and understanding the main Water Cycle in nature. The moisture content of old buildings, which are an integral part of the greater environment, are being driven…

Electro-Hygro-Thermal Changes in Damp Masonry

Humidity and temperature variations in buildings - also known as hygro-thermal changes - are well known among building professionals. Heating creates evaporation, while cooling often results in condensation. Because air always contains quite significant amounts of humidity in vapor form…

Capillary Action vs Soil Evaporation

After doing several experiments on the topic of water absorption into porous bricks, and comparing and cross-referencing the results, we made an interesting discovery about the mechanism of fast vs slow wetting. Experimental Setup Experiment 1: we applied water directly…

Rising Damp Recreated in a Lab

Recreating Rising Damp in the LabRising damp can be recreated in a lab under "artificial" conditions very easily.We used some common "old-style" porous bricks, purchased from a brick factory. We put it in a plastic tray, added some water to…

Controlling Moisture with Non-Invasive Means

The fact that certain wave forms and frequencies affect the movement of moisture in porous building materials, can open the door to new, non-invasive technologies in moisture control - both drying and wetting - applicable to a wide variety of fields,…

Humidity vs. Voltage Changes

Dumping water at the base of a brick sitting in a tray - as we have found out - creates a very fast capillary rise, generating a lot of change quickly. Because most old houses are not sitting in water…

A Typical Wetting-Drying Cycle

Let's analyze in detail the natural wetting and drying cycle of a single brick - the fundamental building blocks of houses. The findings described here also apply to stones and other natural porous building materials.Experimental SetupFor this experiment we used…
