03 Nov Ways To Prevent Damp Walls During Rainy Seasons
During the rainy season, seeping moisture makes damp spots on the internal walls of your home. This results in flaking paint, water damage, mold, fungus, and a chilly and musty atmosphere. These defects often endure after the rainy season is over.
Moisture can do a lot of damage to your walls and home structure over time, so it is critical to get the job done correctly the first time.
What causes damp walls?
Water damage to walls may be caused by blocked pipes.
- Ground moisture may rise higher than ground level, causing walls to be damaged.
- Walls can become moistened by splashing rain water / water build up
- Sloped roofs can hold water, which may seep into the house and cause fractures
- Water can accumulate in blocked drainage pipes, causing damp walls
- Water damage – caused by other structures that are affecting the wall
How to prevent damp walls?
Here are four easy methods or steps that you can take to keep your walls dry:
(1) Check for any cracks in the walls and seal them
The walls of your home may weaken over time, creating cracks that typically start near the door and window frames. These fissures allow dampness to enter your construction, resulting in damp spots.
Proceed to fill the holes and cracks in the wall with crack fill putty.
The loose plaster is then removed from the walls once all the gaps and fractures have been filled. Just remember to do this before the rainy season begins.
(2) Waterproof the external walls and roof
Water can seep through many exterior paints, allowing it to travel from the exteriors of your house to the inside walls.
Exterior waterproofing procedures are necessary for the external surfaces of structures to prevent seepage. Waterproof paint or coating (take note that both are different in nature) will create a barrier against rain water and moisture, preventing damp walls in your house.
Roof waterproofing is just as important as external wall waterproofing. The terrace is exposed to extreme weather conditions, and water easily accumulates on the surface, resulting in seepage and damp areas inside the home. A waterproof roof covering should be applied to the roofs as a sealer that prevents water from seeping through.
(3) Install a damp proof course
A damp proof course is a preventative measure that prevents ground water from rising up through the walls of your home. A preventive barrier of an impermeable substance ( something that cannot allow water to pass through) is built into the brick wall about 150mm above ground level in a damp proof course.
Because of this, any moisture in the ground will not rise up through the walls and cause structural damage.
A damp proof course is usually used when constructing buildings. If you detect damp patches on the bottom of your walls, however, the damp proof course may need to be replaced. This is a time-consuming process that must be carried out correctly. As a result, it’s best to hire a specialist to evaluate the damage and install a new damp proof course.
Keep your home well-ventilated throughout the winter. nTo get rid of any mold or fungus from your walls, make quick steps. As a result, respiratory problems may develop. If you detect excessive moisture or deep cracks in your walls, see a professional right away to prevent wet walls.
(4) Grunting and pressure grouting
You can apply these two techniques if you have enough skill and the right materials and equipment to do so.
Gunting is the technique of coating pipes and walls with a layer of concrete mix, making them water-resistant.
Pressure grouting entails putting a combination of cement and sand into cracks, holes, or fissures in a structure with the help of a jet.
