Rising Damp issues in Doncaster, Grimsby & surrounding areas

---

Rising damp is caused by water from the ground travelling upwards through brickwork by capillary action. The water will contain a number of contaminants found in the ground, such as salts that also travel up the bricks causing further damage to the wall.

The water and salts from rising damp can cause damage to plaster, timber and any absorbent decorative features such as skirting boards and wallpaper. This causes unsightly staining and can lead to rot in structural timbers.

From the mid 1800's, damp proof courses were made mandatory when building new houses.  A damp proof course is a layer of waterproof material in the ground floor wall that prevents the capillary action previously discussed.  There are many different types of damp proof courses that were used in pre 1970's properties including slate, jute, hessian and bitumen.  Unfortunately, these types of damp proof courses can break down over time and this is usually when rising damp occurs.

Damage to a wall can disrupt a damp proof course but they can also be bridged by external factors such as raised flower beds, patios and other cosmetic additions to the outside of a home that can provide ground water with a way around an existing damp proof course.

Any masonry structure unprotected by a properly installed and functioning damp proof course is susceptible to natural rising damp.  Damp will rise by capillary action through the pores of the masonry seeking a means of evaporation.

The moisture will continue to rise until it reaches a height where, unless no evaporation is possible, gravity takes over and pulls it down. This height is seldom more than 1.20m although deposits of salts may be found higher in the internal or external wall, often driven there by the use of non-breathing plasters, renders, ‘tanking’, paints or vinyl wallpaper.
