Are French Drains Positioned Around Slab Foundations Or Pier And Beam Foundations

French Drain and Foundation Drainage, How to for Homeowners

French drains are installed around both types of foundations. Theyre created by digging a trench around all or part of your foundation. A drainage pipe is then placed inside the trench. When this drain surrounds a concrete slab foundations, it helps prevent slab foundation cracks. Keep in mind that when water travels beneath under a slab foundation, it can place hydrostatic pressure on the slab. By utilizing a French drain, a homeowner can minimize the possibility of that occurring. And, because water can also force a slab foundation in an upward direction, installing a French drain around the slab will help eliminate heaving.

When pier and beam foundations are involved, French drains are used to avoid water damage in and around crawl spaces. Pooling water can cause wood to rot, create mold and a whole bunch of other hazardous conditions. Moisture that is trapped in a crawl space can impact the floors of a house and cause them to sag and squeak. High humidity in crawl spaces should definitely be avoided. Take precautions to preserve your house and prevent damage.

If you have noticed water around your foundation, its wise to consult with a drainage specialist. At HD Foundations, we service the entire DFW area. Contact us today.

  • Why You Should Install A French Drain


    French drains are quite popular in Houston and surrounding cities particularly because they can end foundation problems resulting from poor drainage. In most Houston homes, the majority of drainage problems are caused by negative grading and/or improperly designed or installed gutter systems, which fail to divert water runoff away from the foundation.

    Ensuring proper drainage is one of the most important aspects offoundation maintenance. In short, proper drainage allows homeowners to maintain a relatively constant moisture content in the soil around the foundation and prevent the problems that are usually caused by repeated expansion-contraction cycles.

    While repeated expansion-contraction cycles could lead to differential settlement, too much water pooling around a home is one of the primary contributing factors to mold growth, wood rot,concrete spalling, and foundation heave. Any of these problems could lead to foundation failure and additional damage, such as cracks in the walls, doors, and windows that no longer open and close properly, uneven floors, sagging roofs, and tilting chimneys.

    Since excess water around your home is the main culprit behind extensive damage, keeping water away from your foundation is the only way to address and prevent different types of damage that could affect your home.

    How Does Installing A French Drain Around Foundations Prevent Damage:

    It helps you avoid deterioration by forcing the water that is surrounding the foundation into into a safe zone. Its important to remember that water carries a whole lot of weight. In fact, one gallon of water weighs 8.34 lbs. A cubic foot of it weights around 62 lbs. As you can imagine, over 30 of rain per year can mean that a lot of water weight is impacting the soil beneath your foundation. Since the DFW area is known for expansive soil that swells when it gets wet, the dirt under your foundation can shift under the weight of the soil. This is a condition that should be avoided because it can destroy your foundation and negatively impact your house.

    What Are The Required Materials For Proper Foundation Drainage

    Different drainage solutions can require different materials. There are many questions that need to be answered. What is the preferred placement of stone around foundation drainage? What kinds of stone can I use? Where can I get stone? What kind of pipe or tile is required?

    Acquiring the correct materials will help inform you of how to install a foundation drainage system. For a basic french drain, youll need perforated pipe, a geotextile cloth/cover such as a permeable mesh sock, and gravel. Not sure what those materials are or where to find them? Lets break them down.

    Before buying materials, find out which kind of drain pipe is best suited for the job. We break down several of the options and descriptions of other related terms here in our glossary.

    Cost Of Installing A French Drain

    Another factor to keep in mind before installing a French drain is the cost of materials, as well as any costs associated with hiring a professional to complete this work. While this task can be handled by an experienced DIYer, many people may prefer to have the system professionally installed to ensure that it will work effectively. Additionally, hiring a professional can give you better peace of mind because most companies will guarantee their work, so if there are any problems with the French drain or if any other electrical or plumbing lines are damaged during the installation, you can contact the company to resolve the issue.

    The average cost to have a French drain professionally installed is about $5,000, though it can climb to $18,000 for an interior French drain installation. Keep in mind that the longer the drainage trench, the higher the cost of materials. In general, you can expect to pay about $10 to $50 per linear foot for an exterior French drain and about $40 to $100 per linear foot for an interior French drain due to the specialized membranes and additional work required to install this type of system.

    To install an exterior french drain, youll need to do some digging digging up most of your yard, unfortunately! During this step, make sure to avoid any buried power lines, gas lines, or sewage. Youll have to dig a trench around the perimeter of your footing. This trench must be at least two feet wide and six feet deep. For a slab-on-grade home, the trench can be as shallow as two feet.

    Exterior drains can get clogged in a few years and require you to redo this project. In order to make sure this doesnt happen, youll have to place a permeable mesh sock over the drain pipe. Your other option is to install an interior drain. This requires breaking up your basement floor, installing the drainage system, and then rebuilding the floor.

    What Is Collected Surface Water

    Surface water naturally flows downhill using whatever path it chooses. If someone takes some action to concentrate the flow of surface water, this water is called “collected surface water”. If you collect surface water, you have an obligation to discharge that water where it will not cause problems to downstream property owners. If the discharge of collected surface water causes problems or damages on downstream properties, this could be grounds for a lawsuit.

    Examples of collected surface water include:

    • artificial ditches
    • drainage from eavestroughs and downspouts
    • water collected from the roofs of greenhouses
    • discharge from storm water management ponds
    • street curbs and gutters
    • road crossings.

    What Is A Foundation Drainage System

    A foundation drainage system is used to push water away from the foundation and ensure it does not seep in and deteriorate the foundation. This can be done through various methods, including a sump, downspouts, drain pipes, and french drains. The type of foundation system that homeowners choose to use can depend on the surface area of the land as well as the way water will drain from the roof.

    The foundation drainage system will help with basement waterproofing, but it also ensures that the outside walls of the foundation are not continually soaked with excess groundwater.

    French Drains Vs Surface Drains: Purpose

    The main purpose of a French drain is to drain excess water from your garden and the area around your foundation, so that it doesnt get under your home. If your soil is prone to oversaturation from heavy rain or flooding, this type of drain will efficiently channel away any water trapped in the ground.

    Surface drains are used to collect and move away large volumes of water in a short amount of time. They are frequently installed in sloped surfaces like showers and driveways to catch surplus water runoff and drain it away before it can collect and cause serious damage. If the area around your home has drainage issues , a surface drain can prevent it from causing stress to the structure.

    Drainage Solution For Foundation Preservation

    If you have any of the water drainage issues mentioned above, a foundation perimeter drain may be helpful to ensure all excess rainwater is removed to avoid costly foundation problems. French drains are an excellent solution to foundation drainage issues for several reasons:

    • If properly installed, they can operate smoothly for years to come.
    • A quality drainage system can increase the value of your home.
    • They require no special equipment or moving parts, so they dont break down or involve high maintenance costs.
    • Smaller, simpler systems are fairly easy and inexpensive to install, and might be done by an experienced DIY homeowner.

    French Drain pipes are laid at an angle to provide rapid drainage toward the desired low point. The goal is to keep as much water as possible away from your home and foundation. In some of todays houses the drainage system is attached to a sump pump to ensure water flow can keep up with heavy rains.

    Whats The Difference Between A Basement Floor Drain And A Basement French Drain

    A French drain gets rid of the water in the soil under and around your foundation before it has a chance to make its way into your basement. In contrast, a basement floor drain gets rid of water that might, for example, spill out of your washing machine or laundry sink. This is why basement floors are sloped slightly. If your laundry machine overflows, the water flows down the basement floor drain and into either the sewer or into a collection pit where a sump pump then gets rid of it.
