The weather in Brooklyn isn’t what most people will call stable. You might be getting snow or rain earlier or later than you might have predicted.

But how long does interior and exterior waterproofing last? That’s what everyone asks because of how expensive the process can be. And that’s what we will discuss in this article.

Interior Waterproofing

Interior waterproofing is done to ensure that water doesn’t penetrate inside the building. It helps to keep the home’s interior dry and free of water damage. The process is done mostly in areas like the basements and crawl spaces.

Interior waterproofing services are crucial for preventing issues like water seepage and structural damage. It keeps your living areas safe and dry as well.

Methods of Interior Waterproofing

There are multiple ways through which professional waterproofing services do interior waterproofing. Let’s check a few of the popular methods. 


Sealants are materials that you can apply to surfaces like your walls and floors to create a waterproof barrier. They often fill in cracks and gaps where water might seep in. Sealants can be made of different materials, like silicone or acrylic, and are easy to apply with a brush or a caulking gun. Once they dry, they form a strong, water-resistant layer that helps keep moisture out.

Drainage Systems

Interior drainage systems are built to collect and remove any water that gets into your home. One common type of drainage system is the French drain. This system digs out a trench around the basement perimeter and installs a perforated pipe that collects water and directs it away from your home. Another option is a sump pump, which is a device that pumps water out of your basement and away from your foundation. These systems work together to keep your basement dry and prevent water damage.

Waterproof Coatings

Waterproof coatings are special paints or sprays that are appllied to your walls and floors. These coatings create a waterproof layer that stops water from penetrating the surface. They are usually made of materials like epoxy or latex and can be applied with a brush, roller, or sprayer. Waterproof coating is a great way to protect your basement or crawl space from moisture and keep your home dry and comfortable.

Exterior Waterproofing

The opposite of interior waterproofing is exterior waterproofing. This process ensures your home’s exterior isn’t getting any water damage. Water tends to rust and damage a lot of the material that makes up a house over time. 

Damages and issues like basement flooding, foundation cracks, and structural damage. That’s why exterior waterproofing is needed. Exterior waterproofing creates a barrier around your home that stops water from entering.

Methods of Exterior Waterproofing

Exterior waterproofing can be done in several ways, each ideal for a certain building. Let’s examine the most popular methods used by professionals.


Membranes are thick, waterproof layers that are applied to the outside walls of your home’s foundation. These membranes are usually made from materials like rubber or plastic. They are installed to create a strong barrier that prevents water from passing through the foundation walls. Membranes are often applied in large sheets and are sealed tightly to ensure no water can get through. This method effectively keeps your foundation dry and protected from moisture.

Drainage Boards

Drainage boards are installed on the outside of your foundation to help direct water away from your home. These boards are made from materials like plastic or foam and have small channels or grooves that allow water to flow down and away from the foundation. Drainage boards create a space between the soil and your foundation, allowing water to drain more easily. This helps reduce the pressure on your foundation walls and prevents water from seeping in.

Exterior Coatings

Exterior coatings are special waterproof paints or sprays that are applied to the outside walls of your foundation. These waterproof coatings create a protective layer that repels water and prevents it from penetrating the surface. Exterior coatings are made from materials like asphalt or latex and can be applied with a brush, roller, or sprayer. They are an important part of the exterior waterproofing process because they add an extra layer of protection to your foundation.
