Damp penetration is the process of moisture moving from the exterior wall of a building to the interior. This occurs when external moisture, such as rain and wind, hits the wall of a building. Building materials such as brick are porous. They absorb rain, saturate the wall with penetrating moisture.

Rain can penetrate masonry in buildings of any age. In the most obvious case, it penetrates the wall and appears as a damp spot on the interior wall. This causes paint and wallpaper to discolor, peel and peel.
Even if rainwater does not completely penetrate the wall, ingress of rainwater can cause damage to the property. Wind-driven rain in masonry can cause moss growth, increased heat loss and frost damage.
Water leaks through the outer wall and hits the inner walls. There, moisture appears in the form of wet spots on the wall. These spots of penetrating moisture damage wallpaper, plaster and the walls themselves.
Bricks and stones are particularly sensitive to moisture. This is due to their internal structure, which gives them spongy moisture-wicking properties.
How To Treat Damp Walls Internally
Rain penetration is not a problem limited to one wall. Poorly installed connections or cavity wall insulation can allow rain to seep through cavity walls.
In many cases, stormwater runoff is caused by poorly designed or maintained building components (such as blocked drains or leaking gutters), which cause large amounts of rainwater to flood a small area of masonry. In these cases, injecting moisture can usually be eliminated by repairing the defect.
Damage to the roof can allow moisture in and trap it. Typically, roofs need to be inspected for damaged flashing and protrusions, as well as cracked or missing shingles.
The drainage system is also a common place for failure. If external drains become blocked, rainwater can collect on the brick and create hot spots where moisture can penetrate.

Broken gutters can also cause water to fall or collect in uneven areas, as well as moisture and mold growth.
Door frames are also common areas for moisture. General damage, cracks and missing weather seals are things to look out for to prevent moisture from entering through closed doors.
In other cases, rain may be caused by the fact that the stone wall is not waterproof enough to withstand the local weather conditions. The waterproofing of masonry can often be improved by using external plaster, cladding or weather-resistant paint. However, all these decisions change the appearance of the wall.
All construction defects must be corrected as soon as possible. They can allow a constant source of moisture that can damage interior walls, wallpaper, fixtures and fittings, as well as the exterior fabric of the building.
Internal Wall Insulation: The Complete Guide
All bricks are porous and therefore sensitive to moisture. Water seeps through the pores and penetrates deep into the wall.
The more it rains, the more water gets into the masonry. Scratches on interior walls grow in heavy rain. The best way to deal with moisture is to apply a water repellent such as Stormdry Masonry Protection Cream. This can stop further moisture and allow the walls to dry.
Broken bricks and improper orientation can also cause moisture to enter. Damaged brick is less resistant to rain. Wet and damaged brick makes the structure vulnerable.
If cracked bricks or mortar are visible, inspect the masonry to determine the full extent of the damage. Damaged concrete mortars can be repaired and protected from further waterproofing damage by using Stormdry Repointing Additives.

Buildings need to be regularly maintained and precautions taken to protect building structures. Applying breathable masonry waterproofing to wind-exposed buildings reduces water damage and prevents moisture ingress. Houses and flat blocks along the coastline are also at increased risk from salty sea spray and rain from the wind.
Moisture gets in the same way moisture gets in. Leaky appliances such as boilers allow moisture to seep into the walls. The water then passes through the brick and stone rubble in the same way that rain does. Regular maintenance of boilers, furnaces, water heaters, washing machines and taps is essential to keep your home dry.
It is important to remember that penetrating moisture affects buildings of all ages at any stage of operation. If a building has not been treated with a masonry waterproofing cream, it is susceptible to moisture. While waterproof coatings prevent moisture build-up, moisture ingress from wind-driven rain remains a threat.
It can be difficult to figure out what kind of moisture causes stains, mold, wallpaper and plaster in your home. The key to identifying injecting moisture is the height at which it appears.
How To Damp Proof A Wall?
Rising moisture rises from the ground. It will never be found higher than a meter above the building. If the humidity is the wettest on the ground and rises up to a meter from the floor, it is likely that humidity will increase. If the moisture is above a meter and you can’t see the source of the soil, it is likely that it is penetrating moisture.
It is also important to consider the conditions surrounding your humid home. Because of the many possible causes of moisture intrusion, it is often more common than rising moisture.
These two conditions can sometimes look similar and are often confused. Before starting treatment at home, it is necessary to make a proper diagnosis. If in doubt, Safeguard Europe’s customer service team is here to help you with your moisture problem.
When water-soluble salts, such as calcium carbonate or sodium sulfate, are present inside the brick, they dissolve when exposed to moisture. The resulting salt water passes through the capillaries of the brick and is washed away from its surface. The moisture evaporates on the wall, leaving a white powdery substance on the surface. While efflorescence itself is primarily an aesthetic problem, it is a warning sign of moisture within the wall.
Simple Steps To Exterior Wall Waterproofing
If you find efflorescence on your walls, it may be due to moisture seeping through. Water saturation damages brick and mortar. Excess moisture pushes the pressure out and causes damage known as cracking. This refers to the flaking and crumbling that occurs on the surface of the brick.
In severe cases, a crack can damage the integrity of the structure. Parts of the brick and mortar fall off and become weak points in the structure. When this type of damage occurs, trapped moisture will only make things worse. Broken bricks and mortar allow even more moisture to penetrate and cause further damage more quickly.
Sunlight, minerals and water form the recipe for algae growth. Damp exterior walls have all three in abundance. Although the algae appear fragile, these spider green spores are incredibly resilient. Their roots run deep into the masonry and are embedded within the walls.
Algae roots produce acids that disrupt the alkalinity of the bricks and damage them. Likewise, it damages the mortar.

Inside the house, running moisture destroys plaster and plaster. Both types of interior are porous and can absorb large amounts of moisture.
Plaster swells and softens and plaster swells and flakes. This damage is aesthetic and structural. It weakens and damages the wall finish and creates perfect conditions for mold to grow.
Damp brick and stone loads encourage the development of black mold on walls. Black mold is more common indoors due to the higher temperatures required for growth.
Black mold can also grow on exterior walls. Black mold thrives in moist, warm and humid conditions. A combination of cold weather, warm indoor heating and wet walls can lead to the growth of black mold along with penetrating moisture.
How To Treat Damp Walls In Your Home
Black mold is harmful to the health of buildings and people. It’s hard to get rid of this. You must remove the invisible hyphae that is under the substrate as well as the visible mold.
The Dryzone Mold Removal and Prevention Kit can be used to remove and prevent mold for up to 6 months. But this isn’t the only fungal growth to be reckoned with in damp homes.
Where wooden fixtures, furniture and floorboards come into direct contact with a damp wall, moisture will seep through. If fungal spores are present, it can cause wet rot. Moisture penetration causes serious damage if it enters timber structures and requires immediate professional attention.
Cavity walls are widespread in modern residential buildings. Simply put, a cavity wall is a wall that consists of two separate layers – an inner layer and an outer layer. The space between them is where the wall insulation goes.
How To Get Rid Of Dampness And Humidity In The Home
Modern cavity wall specifications usually include drainage holes. They are designed to provide a way for moisture to escape. These openings connect to hollow trays inside the wall that collect and drain moisture that penetrates the wall.
As the moisture is safely drained away from the wall, moisture cannot enter the wall. Provided the drains and sump trays are properly installed, this type of design is effective in preventing intrusion
