The primary difference between exterior and interior waterproofing lies in the installation methods. Exterior waterproofing is mainly fitted from the outside of the basement, requiring excavation around the perimeter and often involves installing moisture barriers to prevent water infiltration.
Interior waterproofing is primarily installed from the inside of the basement, with minimal work conducted outside, and can include measures to relieve hydrostatic pressure.

How to prevent water damage to foundation walls

To prevent water damage to foundation walls, it is essential to waterproof the exterior of the wall, which may involve installing weeping tiles for effective drainage.
By doing so, water infiltration can be stopped before it has a chance to migrate through the foundation wall and cause damage, sometimes utilizing French drains for improved water management.

Difference between waterproofing and dampproofing

It’s important to understand the difference between waterproofing and dampproofing when it comes to protecting your property from water damage, with some cases requiring epoxy injections for crack repair.
Certain sealants and coatings can serve as both for interior and exterior basement walls, providing an effective barrier against moisture. Dampproofing resists only moisture, while waterproofing protects from both water and moisture, often incorporating comprehensive drainage systems for optimal performance.

Waterproof coatings

At Abarent, we prefer to use waterproof coatings and products that degrade during contact with the exterior elements over time, ensuring long-lasting protection.
This provides a much longer term of protection and allows for a longer warranty period.

Lesser-Known Tips for Properly Maintaining Your Basement

• Proper interior insulation and a sealed vapor barrier to prevent humidity and frost on the interior of the foundation wall
• Vertical drains in window wells
• Eve and downspouts installed and maintained to direct roof water away from the foundation
• Top up of compacted soil adjacent to the foundation and maintaining a positive slope for surface water control

Tips for Homeowners to Create a Maintenance Schedule

• Remove exterior sump hose prior to exterior temperatures going below zero
• Cleanout debris from window wells every fall
• Roof eave and drain cleaning to ensure proper function every fall
• Test sump pump and clean out the sump pit twice per year

• Is waterproofing a basement worth it? Waterproofing a basement will provide protection for interior finishes and belongings and generally increase the longevity of the foundation. Proper waterproofing and water control will provide protection against issues such as mold, water damage and structural damage.
• Can I waterproof a basement myself? Waterproofing a basement is not to be considered a DIY project.  Proper analysis of the issue using the proper materials, methods, and knowledge of safe excavation techniques are critical to the project’s success.  We have often encountered DIY projects gone bad that end up costing more than they would have if we had been there from the start due to client missteps.
• How do I stop water from seeping into my basement walls immediately?Water control and any attempt to redirect water away from the affected area will help until the issue can be dealt with on a scheduled basis properly.
• Can you waterproof an old basement? Depending on the condition of the basement there are products that can be used to effectively waterproof most basements regardless of age.  If the foundation substrate is deteriorated there are some alternative water control methods that can be used to enhance the use of the waterproofing products.  Rely on the advice of your Abarent professional to provide the best solution for the situation.
