Bricks do not leak but can absorb moisture, leading to water overflowing and entering the wall. Most stones and standard concrete materials are water-permeable, with the degree of water penetration varying depending on their porosity. Moisture problems in exterior masonry walls can be caused by water leakage, air infiltration-condensation, or a combination of both. There are various mechanisms through which moisture penetrates the walls, such as rain-driven water entering through cracks and penetrations, flashing defects, high hydrostatic pressure outside the foundation, and forcing water into the basement along cracks.
Water coming through brick walls when it rains can compromise the brick’s integrity. It is important for homeowners to recognize warning signs and causes of masonry wall leakage to determine necessary repairs before the brick deteriorates. Unidentified leaks or water seeping through walls may not require significant maintenance or costly repairs.
Wind-driven rain can penetrate brick veneer, solid brick walls, artificial stone, and other masonry materials. Water almost always enters through nearly invisible cracks where the mortar touches the masonry material. A properly built masonry wall does not rely on the mortar to keep the water out. A saturated stone wall can hold water for a few weeks after pointing is finished and for many months before drying out.
Inspections should be conducted to identify entry points like missing mortar or poor flashing that allow “bulk” water to enter the wall cavity. Water can also penetrate to the wood-frame wall and cause damage if the seam between the two claddings is not properly managed during installation. Clear-spray-on waterproofing material on the stones can help prevent moisture from entering the exterior wall, but it won’t solve ground drainage issues if those are the problem.

Stone foundations (also known as fieldstone or rubble foundations) are notorious for water leaks, and many are over a hundred …
Can water go through stone?
Water can flow through rocks, which are essential for groundwater, a valuable natural resource for billions of people. Rocks consist of tiny particles that compact as they are buried, but spaces between them remain, allowing water to flow through and be held there. This process makes the rock part of the groundwater system, or aquifer. Good aquifers have interconnected pores, allowing groundwater to flow through the rock, making it appear solid to the unaided eye. Without these pores, groundwater would not be able to reach the groundwater system.
How do you waterproof an exterior stone wall?
In order to waterproof stonework, it is necessary to apply the initial coat of waterproofer. This should be followed by the application of a liberal wet-on-wet “curtain coat,” which will ensure that the solution drips down 6 to 8 inches over the entire surface. This straightforward outdoor do-it-yourself endeavor can be completed in a relatively short period of time or can serve as a focal point within your outdoor space, providing an excellent opportunity to enhance your enjoyment of the outdoors.
How do you keep water from coming through stone walls?
Waterproofing walls is crucial as mortar and bricks are not entirely waterproof, and excessive moisture can cause internal harm and black mold. Wall coatings can help prevent this issue. Pollutants, precipitation, storms, and algae and lichen growth on walls can cause corrosion, lichen and algae infestations, loss of structural integrity, and damage to wood components.
Splalling brick is when brick fragments fall off the building, causing small cracks to develop into larger ones until the surface deteriorates. If not treated, this issue will worsen and compromise a building’s stability and safety. Spalling bricks increase the likelihood of nearby bricks following suit.
Water is the most common cause of damage to bricks, as it can damage brickwork and degrade surfaces. The freeze/thaw cycle is caused by excessive water trapped within masonry constructions, which expands and freezes in colder temperatures and thaws and loses volume in warmer temperatures. Masonry is subjected to excessive pressure, which can cause cracking and spalling. Water can cause spalling in various ways, such as rainwater eroding brickwork, water leaking from the roof over surfaces due to poor drainage, rising damp or constantly moist soil absorbing water, and even water vapor allowing moisture to enter.
Can water pass through stone?
Rocks comprising crystalline structures, such as granite, are capable of retaining groundwater within their fissures.
Can water seep into stone?
Some types of stone exhibit microscopic fissures or cracks that permit the penetration of water, whereas others are composed of combinations of minerals that attract water.
Should exterior stone walls be sealed?
To ensure maximum protection, seal all stone surfaces. Porous stones may absorb less sealer, but the cost is worth it for added peace of mind. Test absorbency before purchasing sealer, and buy a small bottle if needed. Some granite countertops are pre-sealed, so consult a fabricator or perform a Stone Absorbency Test. New countertops may be pre-sealed, so consult with your fabricator for more information.
Can water penetrate stone wall?
Penetrating damp can disseminate within stone walls, causing damage to the surrounding area and extending into connected timber elements such as ceiling beams or windowsills. As with rising damp, it is of the utmost importance to address rising damp by a professional immediately. The final potential cause of dampness in stone walls is condensation. It is therefore vital to address this issue without delay in order to prevent the occurrence of severe consequences.
Can water leak through stones?
As stone foundations age, they may show signs of water seepage, despite their durability. These foundations are often not waterproof, leading to wall cracking, bowing, and water leakages. Waterproofing is crucial to protect not only the structural support of a foundation but also from water leaking through it, which can cause mold growth. A wet basement is an ideal environment for mold to thrive.
Does sealing stone make it waterproof?
Impregnators are designed to penetrate the surface of natural stones, depositing solid particles or coating minerals below the surface to prevent water, oil, and dirt from entering. There are opposing opinions on whether to seal all or not all natural stone surfaces. Most experts recommend sealing all stone surfaces for maximum protection, but the worst case is when dealing with less porous stones, where the stone will absorb minimal sealer.
The cost of sealers should not be considered a waste of money, but rather an added peace of mind. It is essential to consider the benefits of sealing your natural stone to ensure its longevity and longevity.

Can water break through stone?
The gradual action of water dripping on a rock can result in the erosion of the rock, a process analogous to the melting of snow from a river. At the 10X Growth Con in Miami, John Maxwell put forth a seemingly straightforward yet thought-provoking concept: striking a tree five times with an axe in a personal setting, and then repeating the action the following day. This straightforward yet effective method can assist in the prevention of erosion and the maintenance of a conducive environment for growth.
