Damp basements are absolutely a no-no! Not only do they create an unhealthy environment, but affect the foundation of a building. Most basements in the Bronx, Queens, Manhattan, and Westchester constitute the building’s foundation. Being the lowermost segment of a building, it is almost inseparable from the foundation. Hence, basements promote structural strength and stability in construction.

However, basement moisture is pretty prevalent and one of the most common problems faced by homeowners. A dank basement results in multiple issues like dampening walls and floors, flooding, mold and mildew growth, musty smell, poor air quality, and lastly, causes structural damage. So, basement foundation waterproofing is a prerequisite for safer and healthier living.

Speaking of waterproofing, there are multiple approaches. Some include interior jobs, and some demand exterior service. It often becomes difficult to choose between the two types. Therefore, we have brought this blog to help you understand their unique benefits to ease decision-making. Without further ado, let’s begin.

Understanding Basement Waterproofing Methods

A basement waterproofing solution depends entirely on factors like cost-effectiveness, durability, the type of damage, and damage source. There are two major approaches- interior (internal) and exterior (external). As the names suggest, interior waterproofing is performed within the basement, while exterior foundation waterproofing is executed outside the foundation walls. 

Now, the question is, which method should you opt for? A clear comprehension of both will help you make the right decision.

Interior Basement Waterproofing

It involves practices or approaches that will keep water out of your basement. The process is carried out within your basement space. The popular methods are:

• Waterproof Paints and Coats- Painting the walls and ceiling of the basement with a waterproof coat keeps water out of your basement. It is one of the most budget-friendly options, requiring less time and labor. 
• Patching and Sealing- Another aspect of interior basement foundation waterproofing is sealing and patching minor surface cracks. 
• Vapor Barriers- These are semi-permeable membranes that permit the passage of vapor but do not allow water. Your basement can breathe, yet it will be dry.
• French Drains and Sump Pumps- French drains are underground gutters directing water away from your foundation. Sump pumps are installed in basements to pump out groundwater from the building.

Pros:

• Interior waterproofing basement cost is much less.
• Less invasive with minimum disruption.
• It is applicable in any basement.
• Though it does not offer comprehensive protection, but keeps your basement dry.
• It can be performed at any time of the year.

Exterior Basement Waterproofing

Exterior basement waterproofing is performed on the exterior walls to keep water from entering your building. The popular practices include:

• Grading- Your house will be sloped or graded away from the foundation to prevent rainwater from seeping through the walls.
• Wrapping- In this process, a trench is dug around the foundation, and then the exterior wall is wrapped with a plastic membrane. It ensures comprehensive water protection.
• Gutters- These are installed by waterproofing foundation companies to direct rainwater away from your foundation. 
• Drains- Like French Drains, there are external drain pipes to help the easy flow of rainwater.

Pros:

• It is durable and can last for decades.
• Exterior waterproofing addresses the source of the problem, ensuring greater effectiveness.
• It safeguards the structural integrity of a building.
• Due to thorough water management and increased structural protection, it increases property value.
• Prevents mold and mildew.

To conclude, the basement waterproofing service is obligatory in any circumstance. Allocate your budget and consider the complexities of the project while you make up your mind.
