Table of Contents
Chimneys are wonderful structures as they help to expel fumes and smoke from your home. Unfortunately, as time goes on, it can have damage due to weather elements such as rain and snow. This is why you need to consider waterproofing a chimney.
You might think that waterproofing a chimney is an expensive process. The benefits of doing the work far outweigh the costs involved. A non-waterproofed chimney can lead to severe problems within your home.
Is Water Proofing a Chimney Necessary?
In most cases, a waterproofed chimney at some point in the past will not need re-doing for years. This is beneficial as it shows you may end up saving money while at the same time protecting your home. But when you have never gotten your chimney waterproofed before, you might want to consider doing so.
The benefits of waterproofing are vast and can save you money for years. Prevent future damage to the structure of your chimney. When water gets into your chimney, it can wreak havoc and can compromise even well-constructed brick from this wetness.
Causes of Chimney Leakage
Gain insights on three causes of your chimney leaking. Below is a guide:
Flashing is a thin metal strip that you install around your chimney. When the flashing has damage, water can leak into the chimney. It can cause damage to its structure or interior elements. Remember that water leaking into your chimney can end up damaging the mortar joints. This is why you need to consider replacing such.
The flashing ensures that the connection between your chimney and roof is watertight. This will help keep you safe from any moisture entering into cracks or crevices where it might cause damage to equipment. Prevent fires in case of extreme weather conditions such as heavy snowfall. It can wreak havoc on your home with dry fuel sources nearby such as those made from wood.
Damaged Chimney Cap
A chimney cap is an important part of your chimney. It helps to keep weather conditions, debris, and animals out of it. Prevent moisture from entering the system. When your cap has damage in any way, water can easily get into the structure of your chimney.
Moisture that enters your chimney through a damaged cap will freeze and thaw as seasons change. This will cause the masonry to erode over time. You cannot see this damage from outside. But it can seriously compromise the overall stability of your chimney.
Mortar joints are crucial for your chimney. They hold the bricks together and help keep moisture from entering the system. When these joints are missing, water can get into your chimney and cause serious damage.
Water is a powerful force that can easily damage your home and potentially lead to an expensive repair! Moisture that the masonry absorbs could cause gaps or missing mortar. It will let water access the chimney structure where it is even more susceptible to further damages.
Missing mortar joints in between bricks are a frequent problem on brick chimneys. The porous material often erodes from water damage or cracks. It crumbles out through the accumulating wear incurred when freezing or thawing occurs over time.
Reasons to Waterproof Your Chimney?
Waterproofing helps to protect your chimney against the elements. It benefits you with:

Types of Chimney Waterproofing
Professionals use two types of waterproofing often:
Internal Waterproofing Membrane

External Waterproofing Coating
Apply this coating to the exterior of your chimney. It helps to repel water and protect it from weather damage. This type of waterproofing is more common because it is easier to apply and less invasive than internal waterproofing.
Both methods have benefits and drawbacks. But they both can extend the life of your chimney significantly.
How to Waterproof Your Chimney?

Use an absorbent material on the base of your chimney. You can prevent any run-off from landing on the roof. This can help to prevent serious leaks on your roof and also into your attic.
The absorption of water through the chimney is an inevitable consequence of brick and concrete block construction. Make bricks out of clay or stone. But they still retain some properties that allow them to absorb moisture from their environment. That is when exposed for long periods at a time without drying out quickly enough on their own accord.

How to Waterproof The Foundation of Your Chimney
Gain insights on six ways to waterproof your chimney foundation. Follow the guide below:
When you want to waterproof the foundation of your chimney, you will need to excavate the soil. This will expose the foundation and allow you to apply the waterproofing material.
Build an adequate footing to support the chimney and its enclosure. Excavate around the preexisting structure. Remove any native earth or landfill over it. This is before installing new soil with an acceptable bearing capacity. Build on top of it to not only protect your home’s foundation but also future renovations for the need.
Lay out a strong enough base so as not to damage either one. This means taking time during construction. Mistakes could lead you down difficult paths without proper guidance from professionals. They know what they are doing.
As you may know, there are two types of chimneys: masonry and non-masonry. The difference lies in the material used to build them. Traditionally, bricks were often employed for more durable construction. Use other materials such as sand or concrete, when necessary, with minimal risk.
What is interesting though is how this affects weight. It might seem like all fireplaces would weigh about the same due to their size. They consist mostly of similar components. Some models are heavy that even your small ones will tip the scales around 10,000 pounds!
This is an excellent waterproofing material for foundations! Use often on concrete blocks, brick, and stone. This cement will fill in any cracks or voids and create a watertight seal. Also, use to repair damaged chimneys from water. Mix it with sand to create a thick paste and apply as a coating.
Mix with gravel after laying out the foundation. This will keep it in place and not allow any movement of the masonry over time. Apply your waterproofing material to seal up all openings and joints.
Have an expert review your project before starting on waterproofing the foundation of your chimney.
Mix bentonite clay and water in a bucket – both are half for the correct amount. You can apply it with a trowel or covering machine for larger projects requiring more than one application. This material will absorb water like a sponge. It works as a great temporary sealant to protect your foundation from further damage until you can fully waterproof it.
This method works best in areas with a history of severe weather! Prevent flooding and erosion from affecting your home. It serves a secondary function to eliminate water vapor after exiting the chimney when temperatures change. This benefits fireplace efficiency by ensuring that no moisture enters the firebox or smoke chamber.
When waterproofing the foundation of your chimney, backfill the soil around it with approved drainage material. This will keep water from accumulating and seeping into the foundation. Place a layer of filter fabric over the drainage layer to prevent clogging. Use a perforated pipe for large projects to direct water away from the foundation.
Ensure that you maintain proper water levels. The drainage layer is one foot below the ground’s level at a minimum. You can extend this to two feet as desired. This benefits the future of your chimney foundation for repairs or renovations in being waterproofed.
As you are completing your project, remove all excess material. This includes the old soil that you excavated, and any leftover product not applied to the foundation. No one wants their house covered in the cement mixture. It will only take a day or two for the material to dry. This is a messy task, but it is worth it in the end.
Waterproofing your chimney’s foundation has many benefits that are important for both the short and long term. Taking the time to do it right will ensure that you and your family can enjoy your fireplace for many years to come!
