Understanding Foundation Waterproofing

Imagine your home as a ship sailing through a sea of moisture. The foundation of your home is like the hull of that ship, and just like a ship, it must be waterproofed to prevent water from seeping in. Waterproof house foundations are not just a luxury; they are a necessity for the structural integrity of your home. They support the weight of your house, resist lateral water and soil pressures, and keep insects and cold air at bay. In the same way, waterproof foundation walls and basement walls also play a crucial role in maintaining the overall stability of your home.

However, the primary antagonist in this scenario is water. Water can lead to significant damage if not properly managed through effective waterproofing. The type of waterproofing method chosen depends largely on your home’s location, the integrity of the surrounding soil, and the structure of the foundation itself. With a clear understanding of foundation waterproofing, let’s dive deeper into the types of foundations and the factors that can cause water infiltration.

Types of Foundations

Just as there are different types of ships, there are different types of foundations, each with its unique waterproofing requirements. For example, poured concrete foundations, a common type used in modern construction, must be checked for cracks and defects before waterproofing can be effectively applied. A well-built concrete foundation is essential, as cracks can serve as gateways for water, compromising the overall integrity of the house.

Whether your home sits on a slab, crawl space, or full basement, the type of foundation your house is built on determines the kind of waterproofing that will be most effective. Understanding the distinctive characteristics of your foundation can guide you in choosing the right waterproofing method, helping to ensure lasting protection against water damage.

Causes of Water Infiltration

Now that we’ve considered different types of foundations, let’s move on to the various sources of water infiltration. Remember the ship analogy? Well, if water is the sea, then hydrostatic pressure is the storm that tries to breach the hull of your ship. Hydrostatic pressure is a common cause of water infiltration, and waterproofing can prevent water from penetrating the foundation under this pressure.

Proper landscaping and grading can also prevent water infiltration by promoting proper water runoff and absorption, minimizing the risk of water ingress due to improper drainage. Other factors, such as cracks in the foundation, mortar joints, and movement, can also lead to water infiltration. Understanding these causes can help you choose the right waterproofing method for your foundation.

Choosing the Right Waterproofing Method

Just as a ship’s captain needs to choose the right strategy to weather a storm, homeowners need to choose the right waterproofing method to protect their foundation. Foundation waterproofing is implemented to prevent water from entering a basement from the outside, dealing particularly with hydrostatic pressure. This involves adding a protective material or technique to the foundation to limit moisture infiltration.

Moreover, it’s important to distinguish between damp proofing and waterproofing. While damp proofing aims to halt soil moisture, waterproofing is designed to prevent both soil moisture and liquid water from compromising the foundation. The choice between these two techniques depends on the specific needs of your foundation.

Now, let’s explore the two main types of waterproofing: interior and exterior.

Interior Waterproofing Techniques

Interior basement waterproofing techniques serve as the first line of defense against water infiltration. These techniques involve methods like:

  • Applying waterproof sealants to interior foundation walls and floors

  • Installing interior drainage systems

  • Using sump pumps to remove water from the basement

Such sealants form a watertight barrier that blocks water entry, keeping your basement dry and safe.

You might also come across the following techniques for addressing water intrusion issues:

  • Elastomeric rubberized coatings: a type of waterproof membrane that can be used as an interior sealant

  • Injecting epoxy resin into cracks in the foundation to create a permanent, watertight seal

  • Interior drainage systems: vital for collecting and redirecting water that enters through the walls or floors of a foundation.

Exterior Waterproofing Techniques

Moving on to exterior foundation waterproofing techniques, these methods act as a shield, creating a protective barrier outside of the foundation. They involve the use of waterproofing membranes, which can be made from a variety of materials, offering different methods of creating a watertight barrier.

One popular option is liquid applied membrane. They are spray-applied to the exterior of a foundation, creating a continuous, seamless barrier that prevents water ingress. This technique is like giving your foundation a waterproof coat, effectively shielding it from water infiltration.

Step-by-Step Guide to Waterproofing a Foundation

Having set the theoretical groundwork, let’s now sail into the practical waters with a step-by-step guide to waterproofing your foundation. This process is akin to a journey, beginning with the preparation of the foundation, followed by the application of waterproofing materials, and concluded by installing the drainage systems.

The process of foundation waterproofing might seem daunting at first, like navigating a ship through a storm. However, with a clear plan and the right materials, you can steer your foundation safely through the storm of water infiltration. Now, let’s delve deeper into these steps, starting with the preparation of the foundation.

Preparing the Foundation

Just like a ship needs to be in top shape before it sets sail, the foundation must be properly prepared before the waterproofing process can begin. Preparation involves repairing any damage to the foundation walls, such as cracks or other structural impairments, which is an important step in waterproofing house foundations from the outside.

The foundation walls must be fully cured, free of any loose material, debris, mud, dust, and excess cement before waterproofing. Additionally, surfaces must be smooth, dry, and clean to ensure the best possible adhesion and effectiveness of the waterproofing membrane. Once the foundation is properly prepared, we can move on to the next step: applying the waterproofing materials.

Applying Waterproofing Materials

Applying waterproofing materials is like coating the ship’s hull with protective paint. These materials create a protective barrier for your foundation, keeping water at bay. For waterproofing concrete walls, a combination of a waterproofing membrane and a dimple drainage board is required.

The application process varies depending on the type of waterproofing material being used. For instance, the Geodrain external waterproofing membrane should be installed on the foundation wall by securing, overlapping, and sealing the edges. A neat finish can be achieved with the PermaSEAL Geodrain Capping Strip. Once the waterproofing materials are applied, the next step is installing the drainage systems.

Installing Drainage Systems

Installing robust drainage systems is akin to installing bilge pumps on a ship. These systems help manage water around your foundation, preventing water buildup and maintaining the effectiveness of your waterproofing efforts. A crucial part of a robust foundation waterproofing system is the installation of a French drain, which manages water conveyance and prevents water buildup around the foundation.

Another effective method is the ‘drainage burrito’ method, which uses layers of rock and filter fabric to filter out sediment and maintain the integrity of the drainage system. Other drainage solutions include drainage mats, which create an air gap that encourages the flow of water down to the footing drains, relieving the hydrostatic pressure and protecting the foundation. Now, let’s take a look at some of the waterproofing products and solutions available in the market.

Waterproofing Products and Solutions

Navigating the sea of waterproofing products and solutions can be daunting. But don’t worry, we’re here to guide you through. From waterproofing membranes to sealants, coatings, and drainage solutions, there’s a vast array of products designed to protect your foundation from water damage.

Waterproofing membranes serve as a protective layer for your foundation, similar to the outer hull of a ship. They come in various types, each serving a unique purpose in foundation protection. For example, TPO membranes are often reinforced with polyester and can include additives to meet specific needs. The curing time before membrane application is also crucial, with liquid membranes requiring 14 days or more, while sheet membranes can be applied after a minimum of seven days of concrete curing.

Now, let’s move on to sealants and coatings.

Sealants and Coatings

Sealants and coatings are like the protective paint on a ship’s hull. They play a crucial role in creating a watertight barrier and preventing water damage. There are various types of sealants and coatings, including bituminous coatings, crystalline sealers, and elastomeric coatings.

Polyurethane membranes, for instance, are useful for areas where the waterproofing layer will be overlaid with materials like tiles, screeds, or concrete. Brands like AMES offer basement and foundation sealants and coatings aimed at quickly stopping leaks and combating mold and mildew growth, thus preventing health risks and unpleasant odors.

Now, let’s explore drainage solutions.

Drainage Solutions

As we’ve seen, effective drainage solutions are an integral part of maintaining a waterproofed foundation. These solutions range from basic yard grading to comprehensive installations like gutter systems with extended downspouts, and drainage boards that guide water away from the foundation.

For example, robust drainage systems should employ Schedule 40 PVC pipe, which offers a stronger alternative to the thinner-walled Schedule 20, preventing potential collapse. Choosing the right drainage solution for your foundation can significantly enhance the effectiveness of your waterproofing efforts. Now, let’s weigh the benefits of hiring a professional against undertaking a DIY project.
