Fill any gaps in the wall
To waterproof my garage, I filled gaps in the wall with concrete. This ensures complete sealing of any holes, cracks, or gaps and prevents water damage.
However, it’s essential to note that filling gaps with concrete may not be suitable for all walls. In some cases, using caulk is recommended, such as for tiles or in the bathroom, as it’s more flexible and can withstand movement without cracking.
Before waterproofing, prepare the walls by removing any paint, dust, or plaster for a clean surface. Besides filling gaps, consider other waterproofing methods like applying a waterproof membrane or coating to walls.
This provides an extra layer of protection against water damage. However, it’s essential to assess the type of wall and gap severity before deciding on the appropriate method to prevent water damage.
Interestingly, the Biden administration has also been filling gaps in the border wall in Yuma, Arizona, to prevent illegal immigration. While it may seem unrelated, it highlights the importance of gap-filling as a preventative measure in various contexts.
In summary, carefully evaluate the wall type and gap severity and consider other waterproofing methods for the best protection against water damage.
Apply tanking slurry to the wall
It’s crucial to take extra steps to ensure that your garage is protected from water damage. One of the most effective solutions is to use tanking slurry, which creates a durable barrier against moisture while also being resistant to salts and acids.
To properly apply tanking slurry, it’s necessary to clean the wall and remove any debris to ensure that the slurry can adhere properly. Following the manufacturer’s instructions for mixing the slurry is essential to achieve the right consistency.
Applying multiple coats of slurry evenly will provide the best protection against moisture, and allowing it to dry fully will create a long-lasting and waterproof layer. To strengthen the coating and provide additional protection against cracks and damage, I decided to add a reinforcing mesh to the wall before applying the slurry.
The combination of filling gaps with concrete and using tanking slurry with a reinforcing mesh has fully waterproofed my single-skin garage, providing excellent protection against water damage for many years to come. It’s essential to take all necessary precautions to prevent water damage and protect your garage and its contents.
With the use of tanking slurry and reinforcing mesh, you can have peace of mind knowing that your garage is adequately protected against moisture and potential water damage.
Waterproofing A Garage – A Simple Beginner’s Guide
Waterproofing bottom of garage wall
To fully waterproof the single skin garage, I also applied a damp proofing liquid called Black Jack to the very bottom of the wall on the exterior.
This liquid is made up of bitumen and solvents that are intended to create a waterproof barrier, which is important in protecting the garage from moisture. To use it, I first cleaned the area thoroughly to make sure that it was free from any debris, dust or dirt.
Then, I applied the liquid to the bottom of the wall using either a brush or roller, being sure to cover the entire area evenly. By using multiple coats, I was able to ensure that the liquid would be effective at creating a waterproof layer.
Once the liquid had dried, it created a barrier against moisture that would help to keep the garage dry and protected from water damage.
Another important step in waterproofing the garage was sealing any gaps or holes around the garage door with weatherstripping. Weatherstripping is a thin material that creates a seal between the door and the garage frame and is made of either rubber or foam.
By sealing these gaps, I was able to significantly reduce the amount of water that could enter the garage, and therefore protect it from moisture damage.
To complete the waterproofing process, I also used tanking slurry, which is a waterproofing material that is resistant to salts and acids. This material is applied in multiple coats, ensuring that the wall is completely covered and creating an extra layer of protection against moisture.
By combining these waterproofing methods, including using Black Jack, weatherstripping, and tanking slurry, I was able to ensure that my single-skin garage was fully waterproofed and protected against water damage. It’s important to take the necessary precautions to prevent moisture damage, as it can lead to costly repairs and other hazards in the future
Beware of condensation
It’s important to be aware of condensation when waterproofing a single skin garage. If the garage is completely insulated, it can cause condensation to form on the walls and roof, leading to dampness and potential water damage.
Waterproofing a single skin garage is not only about filling gaps and applying waterproof coatings but also being aware of the potential for condensation.
Insulating the garage completely can cause moisture to build up on walls and roofs, leading to dampness and potential water damage. To prevent this, creating ventilation is essential. This can be achieved by installing a vent or leaving a small gap at the top or bottom of the garage door.
Another option is to create a draft by leaving a window or door slightly open, allowing air to circulate and preventing condensation from forming. It is also important to consider the insulation material used in the garage.
Some materials, such as fibreglass, can trap moisture and contribute to condensation. Choosing insulation that is resistant to moisture or using a vapour barrier can help prevent this.
Maintaining a consistent temperature in the garage is also crucial since rapid changes in temperature can cause condensation to form.
Finally, it’s important to regularly check for any signs of moisture or water damage and address them immediately to prevent further damage. By taking these steps, the garage will remain dry and protected from potential water damage, making it a safe and long-lasting space for storage or other activities.
How much does it cost to waterproof a garage?
The cost to waterproof a garage can vary depending on the size of the garage and the extent of the work needed. On average, you can expect to pay anywhere from $500 to $5000 or more to waterproof a garage.
The cost of waterproofing a garage is affected by several factors, including the materials used, the method of waterproofing, and whether any repairs are needed before the waterproofing work can be done.
To get an accurate estimate of the cost, it’s recommended to get a quote from a professional. Investing in waterproofing can help to protect your garage and its contents from water damage, potentially saving you money in the long run.
Apart from the above-mentioned factors, the cost of waterproofing can also vary depending on your location and the availability of waterproofing professionals. High-demand areas or places with a high cost of living may charge more.
It’s crucial to keep in mind that the cost of not waterproofing your garage can be significantly higher in the long run.
Water damage can cause expensive repairs, mold growth, and damage to your belongings. By investing in waterproofing now, you can help to prevent these issues and potentially save money in the future.
DIY solutions may appear to be less expensive upfront, but they could end up costing you more if they fail to adequately protect your garage. It’s crucial to consider the costs and benefits and choose a waterproofing solution that suits your budget and requirements.
