Save 30% on heating costs without insulating
With a few simple procedures you can easily save 20 – 30% on your energy bill. For this, placing extra insulation is an obvious step, but still. In at least 30% of all houses you can save 20 – 30% on heating costs by not heating moisture anymore.
Rising damp - injecting against moisture problems!
Massimo Pigliucci, science philosopher - Exposing nonsense is our moral duty!
The myth of the so-called "rising damp" stays persistent. Everyone believes it and takes it for true (out of ignorance), while it has nothing to do with the actual cause.
Moisture by ventilating too little? Do not get caught!
Do you notice a moisture problem in your house and do you notice a lot of condensation with possibly some mould here and there, than it’s not because of your way of living. Do not get put off by so called experts, who claim that your moisture problem is caused by your way of living. You should ventilate more and you produce too much moisture by cooking, ironing, washing, cleaning and nightly activities. Nothing is less true.
Thermic setting in (big) buildings
All buildings big or small have to deal with a differential thermic setting between winter and summer. The thermal shrink of concrete is 1/100 mm/m/°C (The hygrometric expansion of bricks εr < 0,1mm/m); this means that the shrinkage cracks can be repaired or evaluated definitively after a (strong) winter. A building of 20m will undergo a theoretic, thermal setting of 20 x 0,01 x 50 = 10mm.
Numbers tell the tale
To measure the present moisture in walls and floors a reliable moisture meter is necessary. A moisture meter with two pins is pushed into wood or other soft materials so the electric resistance can be measured. The same can be done with an analogue or digital Ohm meter. On hard surfaces like bricks, tiles, joints, concrete, natural stone, ... this doesn't or barely works. The pins cannot be pushed into the material. There are other devices on the market for there materials.
Wet spots on the walls
When discovering wet spots on the walls, many people invariably think of rising damp. The wet spots on the walls are only an observation, a superficial visible phenomenon. After a thorough analysis it seems the so-called rising damp does not exist.
Condensation with warm and sultry weather
With warm and sultry weather condensation on the floor of an underground parking (or another cold floor) can occur.
This phenomenon occurs everywhere a few times a year. Many little drops form puddles of water, so it seems that the underground construction leaks.
