Basement leaks are a common issue faced by homeowners and commercial property managers alike. A leaking basement can lead to severe structural damage, mold growth, and a host of other problems if not addressed promptly and effectively. At AnyLeak, we specialize in comprehensive basement leak repair services, leveraging advanced technology and a team of skilled professionals to provide effective and long-lasting solutions.

Understanding Basement Leaks

Common Causes of Basement Leaks

Hydrostatic Pressure: This is the pressure exerted by water in the ground around the basement walls. When the soil is saturated, the pressure increases, forcing water through any cracks or weak points in the foundation.

Poor Drainage: Inadequate drainage systems can cause water to accumulate around the foundation, leading to leaks. This includes improperly graded landscapes that direct water toward the basement rather than away from it.

Cracks in the Foundation: Structural weaknesses, such as cracks in the walls or floors, provide easy pathways for water to enter the basement.

Faulty Waterproofing: Poorly applied or deteriorated waterproofing materials can fail to keep water out, resulting in leaks.

Window Well Issues: Basement windows that are not properly sealed or are below ground level can allow water to seep into the basement.

Types of Basement Leaks

Wall Leaks: These leaks typically occur through cracks in the basement walls. They are often caused by hydrostatic pressure, settling of the foundation, or freeze-thaw cycles that expand existing cracks.

Floor Leaks: Water can seep through cracks or joints in the basement floor. This type of leak is often due to high water tables or poor drainage systems.

Cove Joint Leaks: The cove joint is where the basement floor meets the wall. Water can enter through this joint if there is significant hydrostatic pressure or if the waterproofing is compromised.

Window Leaks: Leaks around basement windows can occur due to improper sealing, damaged window wells, or poor installation.

Sump Pump Failure: A sump pump is designed to remove water that accumulates in the sump basin. If the pump fails, it can lead to basement flooding and leaks.

Our Approach to Basement Leak Repair

Initial Assessment

Thorough Inspection: Our process begins with a detailed inspection of the basement to identify the source and extent of the leak. This includes examining walls, floors, windows, and drainage systems.

Moisture Mapping: We use advanced moisture mapping technology to pinpoint areas of high moisture content and potential leak sources.

Soil and Hydrostatic Pressure Analysis: Understanding the soil composition and hydrostatic pressure around the foundation helps us determine the most effective repair strategy.

Repair Solutions

Crack Injection

Epoxy Injection: For structural cracks, we use epoxy injection to fill and seal the cracks. Epoxy is a strong adhesive that bonds to the concrete, restoring its structural integrity and preventing water ingress.

Polyurethane Injection: For non-structural cracks, polyurethane injection is used. This material expands upon contact with water, effectively sealing the crack and providing a waterproof barrier.

Interior Drainage Systems

French Drains: Installing a French drain system along the perimeter of the basement floor helps to divert water away from the foundation. This involves creating a trench, lining it with gravel, and installing a perforated pipe to collect and channel water away.

Sump Pumps: We install and maintain sump pump systems to manage water accumulation in the basement. Our pumps are equipped with battery backups to ensure functionality during power outages.

Exterior Waterproofing

Excavation and Membrane Application: Exterior waterproofing involves excavating around the foundation to apply a waterproof membrane. This membrane acts as a barrier, preventing water from penetrating the basement walls.

Drainage Boards and Gravel: We install drainage boards and gravel layers to facilitate water drainage away from the foundation, reducing hydrostatic pressure.

Interior Waterproofing

Waterproof Coatings: Applying waterproof coatings to basement walls and floors can provide an additional layer of protection against water ingress. These coatings are designed to withstand hydrostatic pressure and are highly durable.

Vapor Barriers: Installing vapor barriers on basement walls helps to prevent moisture from seeping through and causing mold growth or structural damage.

Advanced Technologies

Infrared Thermal Imaging

Using infrared thermal imaging, we can detect hidden moisture and temperature variations within the basement walls and floors. This non-invasive technology allows us to identify potential leak sources without extensive drilling or excavation.

Acoustic Leak Detection

Acoustic leak detection involves using sensitive microphones to listen for the sound of water leaking through cracks or joints. This method is particularly useful for pinpointing the exact location of leaks that are not visible to the naked eye.

Moisture Sensors

We install moisture sensors in critical areas of the basement to monitor humidity levels and detect any increase in moisture content. These sensors provide real-time data, allowing us to take proactive measures to prevent leaks.

Preventative Measures

Regular Maintenance

Annual Inspections: Regular inspections of the basement and surrounding areas can help identify potential issues before they become significant problems. We recommend annual inspections to ensure the integrity of the waterproofing systems.

Drainage System Maintenance: Keeping drainage systems, including gutters and downspouts, clear of debris is essential to prevent water accumulation around the foundation.

Landscape Management

Proper Grading: Ensuring that the landscape around the foundation is graded to direct water away from the basement is crucial. We provide grading services to correct any issues and improve drainage.

Plant Selection: Choosing plants with deep root systems can help absorb excess water and stabilize the soil around the foundation.

Waterproofing Upgrades

Enhanced Membranes: Upgrading to more advanced waterproofing membranes can provide better protection against water ingress and hydrostatic pressure.

Advanced Drainage Solutions: Implementing advanced drainage solutions, such as underground piping systems, can enhance the efficiency of water management around the foundation.

Case Studies

Residential Basement Leak Repair

Initial Situation

A homeowner in Vancouver, BC, contacted AnyLeak after noticing water pooling in their basement following heavy rainfall. Our team conducted a thorough inspection and identified multiple cracks in the foundation walls and an ineffective drainage system.


We implemented a multi-faceted approach, including epoxy injection to seal the cracks, installation of a French drain system, and the application of an exterior waterproof membrane. Additionally, we installed a new sump pump with a battery backup to manage future water accumulation.


The basement remained dry during subsequent heavy rains, and the homeowner was satisfied with the long-term solution provided. The property value also increased due to the improved structural integrity and waterproofing measures.

Commercial Property Leak Repair

Initial Situation

A commercial property manager in Burnaby, BC, reported persistent basement leaks that were affecting tenant businesses. Our inspection revealed that the leaks were primarily due to hydrostatic pressure and inadequate exterior waterproofing.


Our team excavated around the foundation and applied a high-performance waterproof membrane. We also installed drainage boards and a robust exterior French drain system to manage water flow. Interior waterproofing coatings were applied to the basement walls for added protection.


The commercial basement remained leak-free, significantly reducing maintenance costs and tenant complaints. The property manager was impressed with the efficiency and effectiveness of our solution.


Basement leaks can cause significant damage if not addressed promptly and effectively.
