Exterior Basement Waterproofing

Our Comprehensive Exterior Basement Waterproofing Services

At 20,000 Leaks Under The Basement, we offer a range of services tailored to meet your specific needs:

Foundation Waterproofing

Our foundation waterproofing involves applying an impermeable waterproof, bituminous membrane to the exterior walls of your basement and foundation footings. This method is ideal for preventing water from seeping through cracks and porous surfaces such as CMU blocks. Learn more about our foundation wall and crack repair services.

Exterior Drainage Systems

We install exterior drain systems, such as perimeter drain tile, if not present and box and field drains with solid pipe to divert water away from your foundation. This service works in tandem with foundation waterproofing to provide comprehensive protection. Discover more about our stairwell drain installation services.

Downspout Leads

We re-route and bury your downspout leads to divert rainwater away from your foundation. This simple yet effective solution significantly reduces the risk of basement flooding and foundational water damage. Explore more about additional exterior waterproofing services.

Steps in Our Exterior Basement Waterproofing Process

We follow a systematic approach to ensure effective and lasting results:

Step 1 – Inspection

Our experts conduct a thorough assessment of your property’s basement foundation on the interior and exterior to identify vulnerabilities, accessibility and sources of water intrusion. This initial inspection determines the appropriate waterproofing solution either from the interior, exterior or both.

Step 2 – Custom Plan

Based on the inspection, if so determined, we develop a tailored exterior waterproofing strategy that addresses your home’s specific needs and site conditions.

Step 3 – Property Marked

Before starting the excavation, we reach out to local utilities companies to mark your property to determine where their lines are buried.  This includes, electric, gas, water and cable/internet lines.  We also make sure to note where well lines enter your property.

Step 4 – Excavation

We carefully excavate around the foundation walls to the foundation footing to expose areas requiring treatment, ensuring minimal disruption to your landscaping.

Step 5 – Foundation Wall Treatment

We then clean, repair and apply a waterproof primer and membrane to the foundation walls, including the footings, to create a watertight barrier.

Step 6 – Drainage System Installation

We install exterior drain tile, when not present, to direct water away from the foundation effectively.

Step 7 – Backfilling and Restoration

After repairs and installations, we backfill and tamp the excavated areas and restore as best possible your landscaping to its original condition.

Commonly Asked Questions for Exterior Basement Waterproofing

How do I waterproof my basement from the outside? Waterproofing a basement from the outside involves excavating around the foundation, cleaning and repairing the exterior walls, applying a waterproof membrane or coating, and if necessary installing proper drainage systems to direct water away from the foundation.

What is the best waterproofing for exterior foundation walls?

The best waterproofing for exterior foundation walls typically involves applying a high-quality, self-adhering waterproof membrane to effectively prevent water intrusion.

What is exterior basement waterproofing?

Exterior basement waterproofing, also known as positive side waterproofing, is a method used to prevent water from entering your basement by applying waterproofing materials and techniques to the outside foundation walls and footings of a home.

Is it better to waterproof your basement from inside or outside?

Both interior and exterior basement waterproofing methods have their advantages and are suitable for different situations. Exterior waterproofing focuses on preventing water from entering the basement by addressing the issue from the outside, which is effective in protecting the foundation and preventing structural damage. However, it is more labor-intensive and costly due to excavation and material requirements. Interior waterproofing, on the other hand, manages water that has already entered the basement, using perimeter drainage systems below the basement slab with sump pumps and installed air gap membranes at the cove area, half or full wall. The choice between the two methods depends on factors such as accessibility to the perimeter basement walls, the location of the water intrusion, the severity of the water problem, and specific property conditions.

For a comprehensive solution, combining both interior and exterior waterproofing methods can provide optimal protection against water intrusion.
