Which Type Of Waterproofing Is Superior, External Or Interior?

Interior waterproofing is a more affordable option that focuses on managing water that has already entered the home. Exterior waterproofing prevents water infiltration from occurring by targeting potential entry points at the foundation walls. Both methods provide comprehensive protection against water infiltration and damage, but interior waterproofing redirects water that has already entered the basement.

Exterior waterproofing is installed from outside the basement, meaning excavation around the perimeter of the basement is necessary. Both systems keep the inside of the basement dry, but each has its pros and cons that are more suitable or less suitable to each homeowner. Interior waterproofing is best suited for existing buildings where exterior access is limited or excavation is not feasible. It effectively addresses basement issues.

Eyewaterproofing lasts longer without maintenance than interior waterproofing due to its direct impact on the structural integrity of the building. Exterior waterproofing creates a barrier that prevents water from entering the home, while interior waterproofing redirects water that does enter the home. Interior basement waterproofing systems are considered better and more effective in preventing wet basements.

For houses with concrete foundation blocks, an exterior approach is a better option. Seepage through cracked mortar joints or through the porous block itself is less likely to occur through interior waterproofing. Interior waterproofing pumps out water that has already entered the basement, as opposed to exterior waterproofing, which keeps it out.

Which type of waterproofing is most expensive waterproofing?

Polyurethane liquid membrane waterproofing is a costly method used for flat roof areas exposed to weathering. It offers higher flexibility but is sensitive to moisture content, so careful evaluation is necessary before application. Applications include roofs, balconies, terraces, wet areas, water tanks, pedestrian decks, parking decks, bridges, detail waterproofing, decorative waterproofing, and polyurethane foamed roofs. However, it is sensitive to moisture content, causing peeling or de-bonding after application.

Is it better to fix a leaky basement from the inside or outside?

What is the best time to do waterproofing of your home?

The best time to waterproof a home is during construction, as it provides the most access and minimizes distribution to homeowners. However, waterproof membrane failure can occur over time due to various reasons, including bad workmanship, deterioration over time, incorrect installation, or incorrect installation in the first place. In 90% of cases, these issues can lead to membrane breaks and potential damage to the property.

Should I waterproof the outside of my house?

Waterproofing exterior walls is crucial to prevent damage and increase home value. When exposed to rainwater or high humidity, moisture can travel through masonry and affect internal walls, leading to mold growth and irreparable damage. In humid areas like Florida, water penetration is a matter of when walls are damaged. To prevent water and mold from affecting walls, follow seven steps: use a concrete waterproofing coating, a silicate-based concrete sealer, or waterproofing paint.

Choose a breathable formulation designed to allow walls to breathe and eliminate moisture, and apply it to surfaces previously painted. These methods ensure that walls are protected from water penetration and mold growth. In humid areas like Florida, wall damage due to water penetration is a matter of when, not if.

Is it better to do interior or exterior waterproofing?

Exterior basement waterproofing is a more expensive and complex procedure compared to interior basement waterproofing, which requires the expertise of laborers for efficient results. Hiring a contractor with less experience may result in higher costs in the long run. Exterior waterproofing is more involved and is considered a preventive method for keeping basements dry. Interior systems redirect water out of the home by digging a water collection trough and installing a sump pump, while exterior systems are installed outside the foundation to prevent water from entering the basement.

The exterior waterproofing process includes excavation of soil and repairing leaks using a sealant. Interior basement waterproofing systems are considered more effective in preventing wet basements. Dry-Tech Waterproofing Solutions offers premium solutions for waterproofing basement walls from the inside, addressing water seepage, leakage, and flooding issues.

What is the difference between internal and external waterproofing?

Exterior waterproofing is typically installed outside the basement, requiring excavation around the perimeter, while interior waterproofing is typically done inside the basement. A sump pump is typically required for interior waterproofing to prevent water accumulation in the weeping tile network. The necessity of a sump pump for exterior waterproofing depends on the property’s unique needs, such as a high water table.

If used for exterior waterproofing, it can be outdoors due to the weeping tile network being outside. Although not entirely necessary for exterior waterproofing to keep water out, it is a great way to prevent water from pooling around the waterproofed foundation.

What is the best method for waterproofing?

Bituminous coating waterproofing is a method of securing surfaces through the application of a mixture of bitumen and filler materials, such as gravel or sand. This mixture is heated and then applied using a roller or brush.

Which type of waterproofing is best?

Polyurethane is a highly versatile waterproofing material that can be applied seamlessly and penetrates surfaces deeply, filling even the smallest cracks in concrete. It resists oil, detergents, and chemicals, making it suitable for walls, balconies, terraces, and walls. The average application price is $10 per square meter of building.

Cementitious coating is a powder mix of sand, organic, and inorganic substances plus silica-based materials, popular among waterproofing contractors due to its ease of application. However, it lacks flexibility and is not recommended for basements and foundations. It is also affordable, costing between $2 and $4 per square foot installed.

EPDM rubber is a recommended waterproofing material for roofs, available in two thicknesses: 45 mils and 60 mils. Its flexibility is crucial for roof waterproofing, as it expands and contracts constantly due to temperature variations. The cost varies depending on thickness and brand, ranging between $3. 25 and $15 per square meter.

What is the cheapest method of waterproofing?

The most cost-effective waterproofing method is dependent upon the specific project and requirements, but cementitious coatings or acrylic-based products may be some of the more cost-effective options.

How many years does waterproofing last?

Waterproofing systems can last up to 15-20 years on their own, but it’s crucial to work with a professional contractor for quality installation and materials. If your basement needs waterproofing, you can detect it by the presence of water or water stains on walls and floors, a musty smell, or excessive humidity. These signs indicate that your basement is not adequately protected from moisture and should be treated accordingly.

How long does exterior waterproofing last?

The typical lifespan of basement waterproofing is at least a decade, contingent upon factors such as climate, damage, and the composition of the existing materials. Groundwater is a ubiquitous phenomenon in residential properties of all ages and construction types, with water levels exhibiting seasonal fluctuations. It is therefore imperative that a waterproofing system is employed which facilitates the removal of water, rather than impeding its ingress.
