Question 1

What to Know About Foundation Waterproofing?

Accepted Answer

Effective foundation waterproofing goes beyond simply keeping water away from your foundation; it focuses on ensuring that your foundation stays dry, regardless of water presence in the surrounding area. Many less-experienced contractors overlook this key distinction.
Proper waterproofing begins with accurately identifying the source of water intrusion. Moisture can seep in through walls, floors, joints between floors and walls, or even over the top of walls. Pinpointing the entry point while seepage is actively occurring is crucial to developing the right solution or structural repairs. At Wet Basement Specialist, our team uses proven techniques to diagnose and resolve foundation leaks, ensuring your property remains safe and dry.

Question 2

What’s the Difference Between Foundation Dampproofing and Foundation Waterproofing?

Accepted Answer

Foundation dampproofing is typically applied during the initial construction phase to meet basic building code requirements. In cases of unfinished basements, most building codes only mandate dampproofing. Unfortunately, this leads many builders to overlook the crucial differences between dampproofing and waterproofing.
Dampproofing usually involves applying a hot liquid asphalt and rubber coating with an insulating panel. While it can deter some moisture, it does not prevent water penetration from the outside, as the coating is applied internally.
Foundation waterproofing, on the other hand, effectively addresses moisture seepage and hydrostatic pressure exerted against the external foundation. Unlike dampproofing, a waterproofing system is applied externally to the foundation, creating a barrier that prevents water from seeping in. At Wet Basement Specialist, we prioritize proper waterproofing methods to keep your foundation safe, dry, and fully protected from water intrusion.

Question 3

How does water come through the walls?

Accepted Answer

Poured concrete foundation walls are often vulnerable to water penetration through cracks. Approximately 98% of these cracks form within the first 30 days after the walls are poured, typically due to natural shrinkage or construction practices rather than structural flaws. While some cracks may not be immediately visible, they can become apparent over time as the cement within them begins to deteriorate.
Unchecked seepage through these cracks can worsen, leading to costly repairs, time-consuming cleanups, damage to possessions, poor indoor air quality, and the need for professional waterproofing. Other common causes of wall leaks include tie rod ends, honeycombed concrete, and pipe penetrations. At Wet Basement Specialist, we are experienced in identifying and addressing these issues to protect your home from water damage.

Question 4

How Does Water Enter Over the Top of the Wall?

Accepted Answer

This type of leak is commonly caused by one of two below-grade issues: improper soil grading or attempts to raise the dirt level above the concrete wall, leading to seepage through below-grade brick or siding.
Above-grade water penetration can also occur due to issues such as improper caulking or tuckpointing of finishing materials like siding. When moisture infiltrates the veneer of the foundation, it can run down behind the finishing materials and spill over through the sill-plate juncture—similar to a shower curtain hanging on the wrong side of a tub. Improperly directed downspouts can also contribute, as roof water that isn’t diverted far enough from the foundation can saturate the soil, causing leaks through this same juncture.
To identify whether a concern is below-grade or above-grade, saturate the ground around the foundation. If water enters the basement, it’s a below-grade issue requiring grading correction. If no water penetrates, it’s an above-grade concern, needing repairs to waterproof the foundation.
For stone, block, or tile foundations, specialized waterproofing systems are necessary, and it’s best to consult with a foundation waterproofing specialist. For quick and effective solutions to poured concrete foundation seepage, a professional assessment is recommended. Our team at Wet Basement Specialist has the expertise and products to resolve these issues with top-tier solutions.

Question 5

How does water come through the floor or floor/wall joint?

Accepted Answer

Water seepage through the floor or floor/wall joint often results from issues with the home's drain tile system. These systems, installed around the footings, are designed to channel water away from the foundation and support effective waterproofing. If the drain tile system is missing, compromised, or fails, it can lead to hydrostatic pressure building up against the floor and floor/wall joint, causing water intrusion.
Modern building codes no longer permit drain tile systems to discharge water directly into city storm sewers, which can further increase pressure around a home’s foundation. Sump pumps have since become a common solution, efficiently directing water from sump pits away from the foundation. However, if leaks persist despite a properly functioning sump pump, it often points to an underlying issue with the drain tile system that requires professional attention.

Question 6

How Long Does a Waterproofing Job Take?

Accepted Answer

The duration of a waterproofing job can range from one day to a week, depending on several factors:
 • Type of foundation (concrete or stone)
 • Material that needs to be dug through (dirt or concrete)
 • Depth of the footing
 • Length of the foundation that requires waterproofing
 • Accessibility of the areas being worked on
 • Number of cracks and repairs needed
 • Any unforeseen issues discovered during excavation
Each project is unique, so the timeline will be tailored to your specific needs.
