How to Deal with Efflorescence
How to Deal with Efflorescence
Did You Know
Efflorescence is a common occurrence when the concrete or mortar used for the construction of your basement contains excess salts. The salts are leached to the surface of the foundation walls as a result of water transfer. This results in white salt deposits on the surface of the foundation.
These deposits often appear within the first year of construction of the foundation. Although they are often viewed as an aesthetic concern, they can become a structural problem if the situation is not properly resolved.
Preventing Efflorescence
Whether you’re in the planning stages of construction or are dealing with an already constructed home, there are several steps you can take to help you avoid efflorescence. These include:
1. Choosing your materials carefully
The content of the materials you use for construction contribute to the characteristics of the material. It is important to choose materials that have low quantities of slats. This will greatly reduce the potential of the formation of salt deposits.
It is also important to be careful with the equipment you use. Ensure that it is properly cleaned after use. This prevents the transfer of contaminants during mixing or laying materials.
2. Waterproofing of basement
Ensure that the basement is waterproofed properly. This keeps the moisture out of the foundation walls. With the water kept away, there is little or no chance of deposits forming.
3. Treat the surface of the walls
Treating the surface of the walls with a water-repellent material will restrict the penetration of water to the surface of the walls. This will minimize salt deposits on the surface
How to remove deposits
When you discover salt deposits on your foundation wall, you will probably want to get rid of them as quickly as possible. How they are handled will depend on whether they are soluble or insoluble salt deposits.
Soluble salt deposits can be removed by simply dry brushing them off the surface of the wall. You can use a stiff-bristled brush for this. Insoluble salt deposits ought to be dissolved using a dilute acid. Care should be taken to prevent discoloration of the surface.
It is important to remember that getting rid of the deposits on the surface of the walls is not a permanent solution. It is only aesthetic. The deposits are likely to return if the underlying cause is not dealt with. It is therefore important to contact a waterproofing contractor to ensure that water can no longer infiltrate the foundation walls.

Different types of foundation problems will deteriorate at different rates. For example, problems related to water infiltration and hydrostatic pressure can lead to rapid deterioration, while problems related to tree roots may take longer to cause significant damage. Understanding the type of foundation problem you are dealing with is essential for determining how quickly repairs are needed.
The severity of the foundation problem will also impact how quickly it deteriorates. Minor cracks or bowing in the walls may take longer to worsen than more significant structural damage. However, it is important to note that even minor issues repair cracks can quickly turn into major problems if left untreated.
Climate and weather conditions can also impact the deterioration of foundation problems. For example, areas with high levels of rainfall or heavy snowfall may experience more rapid deterioration due to water infiltration and freeze-thaw cycles. Similarly, areas with high levels of soil moisture may experience more rapid deterioration due to the effects of hydrostatic pressure.
The type and condition of the soil surrounding the foundation can also impact the deterioration of foundation problems. For example, expansive soils can lead to significant movement and cracking of foundation walls, while poorly compacted soil can lead to settling and sinking of wall surface of the foundation.
The level of maintenance and repair work performed on the foundation can also impact its deterioration. Regular inspections and maintenance can help to identify and address problems before they worsen, while timely repairs can prevent minor issues from turning into major structural damage.
The age of the foundation can also impact its deterioration. Older homes and foundations may be more prone to damage due to wear and tear over time. Similarly, foundations that were not constructed to modern standards may be more susceptible to damage.
