How To Set Up A Footer Drain Inside?

Footing drains, also known as drain tile, are essential in areas where the ground saturates during any time of the year, particularly if the home sits on a basement. They are exterior drainage systems located just outside the foundation wall and drain water away from the floor. To install a foundation drain, a trench is jackhammered into the floor, and a perforated pipe and stone bed are installed to lead the water away. The floor is then concreted over again.

In this video, we assemble and install the foundation French drain around the perimeter of the basement. We dug a trench below the top of the footing, laid th… We’re about to install interior footing drains of 4″ perforated pipe with filter fabric sock on 1″ bed of 3/8″ gravel covered with 1″ gravel before insulation, VB, and 4″ concrete slab. The pipe will lay 1″ away from the foundation.

Footing drains are essential to protect your home’s foundation and ensure that the center of the drain pipe is below the top of the concrete slab floor inside the basement. Most detail drawings show that a footing drain should be located next to the footing, but some builders prefer placing the drain pipe on top of the footing. Place the fabric along the trench, making sure it’s wide enough to wrap around the drainage pipe and gravel.

In conclusion, footing drains are crucial for maintaining a safe and functional foundation. They are essential in areas where the ground saturates during any time of the year, especially if the home sits on a basement.

Can a drain pipe go through a footing?

In the event that pipes are to be installed beneath footings or foundation walls, it is imperative that a relieving arch or pipe sleeve be incorporated into the wall structure. The sleeve should be of a size that is two pipe sizes larger than the pipe passing through the wall.

Do footing drains work?

Footing drains are a popular method for managing water around a home’s foundation, but they may not always be the most effective or cost-effective solution. Factors like soil type, landscape, and existing water issues can affect their effectiveness. Consulting with a foundation waterproofing expert is crucial for determining the best solution.

French drains are a flexible and cost-effective alternative for managing water drainage around a property. They consist of a perforated pipe in a gravel-filled trench, covered with breathable fabric to prevent soil from clogging. French drains are designed to redirect water away from problem areas but are typically installed farther away from the foundation. They can be used in various landscape settings to address pooling water, soggy lawns, and other drainage issues.

What is an interior footing drain?

Interior footing drains are a waterproofing method installed around a home’s foundation to prevent water from seeping into the basement or crawlspace. They are installed by removing the edges of the concrete slab, digging a trench around the foundation, placing a perforated pipe in the trench, covering it with crushed stone, and pouring concrete over the trench. Most interior French drains work with existing sump pump systems to remove collected water from the basement. However, homeowners should consider the pros and cons of installing these drains before installation.

What is the best pipe for a footing drain?

The International Residential Code (IRC) section 1 mandates that drains surrounding concrete and masonry foundations should remain below grade, except for well-drained soils and soils with sand and gravel mixtures. Heavy rains and flooding can overload a foundation drain system, but drainage boards can mitigate this risk by quickly draining off water and preventing hydrostatic pressure next to the foundation wall. Most contractors prefer rigid drain tile for basement footer drains, while flexible corrugated plastic pipe is an expensive option but may get crushed during the backfilling process.

Soil moisture is another factor to consider when choosing drainage solutions. Moist soils do not drain as well as dry soils, and flood-prone areas need other drainage solutions. Trees should be planted no closer to the foundation than their eventual height, as tree roots can fill perimeter drains and damage the foundation drain system.

Foundation drains are often used by contractors to protect foundations from settlement. They prevent water accumulation near the building’s foundation, reducing the risk of settlement and pest breeding. They also help prevent soil erosion and remove toxic organisms from stagnant water, which can become a breeding ground for disease-ridden pests and create swamp-like surface conditions.

What does a footing drain look like?

The footer drain is connected to a sump pump, and as water enters or moves against the wall, it encounters the drain as it flows down.

How much slope does a PVC drain pipe need?

The slope of horizontal drainage piping can be classified into one of two categories: 1/2 or less (1/4a3) and 61/8a8 or larger (1/16a).

What do footing drains connect to?

Footing drains typically drain to a storm sewer, sump pump, or the surface. Storm sewers are ineffective due to their inability to tilt downwards and their limited water storage capacity. Footing drains that discharge to the surface can work until the drain clogs, but only in situations where the drain does not have to run uphill. A downhill incline is not possible unless the ground drops off around your home more than 8-9 feet.

A sump pump can actively pump water out of your house, reducing the need for a natural downhill incline and ensuring water removal. However, the sump pump cannot help if the footing drain leading to it is clogged and filled with dirt. Overall, footing drains are essential for water management in your home.

What is the pitch of a footing drain?

Proper drainage in foundation footings requires a slope of one-eighth inch per foot, with the footing drain being perforated but the outlet pipe having no perforations and sloped away from the foundation footing. The drain pipe should be low enough to prevent water from reaching the footing top, with the best spot being a few inches below the footing and at least a half-foot under the slab. To prevent clogging, weeping tile should be laid in coarse gravel or crushed stone covered by industrial strength filter fabric, creating a solid seal.

Is a footing drain the same as a French drain?

Footing Drains are exterior French drains installed against the exterior of a basement wall, alongside the footing. They consist of a perforated pipe surrounded by gravel and wrapped in filter fabric, which acts as a filter to prevent material from entering through the perforations. Foundation drains ensure water follows the least resistance path, preventing problems like mold, cosmetic damage, and structural failure. By properly installing foundation drains, homeowners can prevent issues like structural failure and ensure the basement walls and floor remain waterproof.

How do you install interior footing drains?

Interior footing drains are similar to exterior footing drains but installed inside the basement. They involve a trench jackhammered into the floor, a perforated pipe and stone bed installed to drain water, and the floor is then concreted. This method leaves a gap between the floor and wall, allowing water from the wall to flow down into the drain. This seepage can be caused by window wells, wall cracks, pipe penetration, or condensation.

The drain is not outside the basement but is still in backfilled soil, which can cause clogging problems. Over time, soil may wash in and clog the system, potentially causing structural issues. The gap between the wall and floor allows water to flow in, collecting debris from the basement floor and clogging, making the home appear unsightly. To prevent this, it is recommended to have an interior footing drain installed.

How deep should a footing drain be?

The ideal depth for a footing drain is typically 6-8 feet below the ground surface, ensuring it is below the frost line and effectively collecting water seeped into the soil. Footing drains can last for many years, but their lifespan can vary depending on factors like installation quality, soil and drainage materials used, and water handling capacity. Proper maintenance and periodic inspections can extend their life.

Installing a footing drain yourself is technically possible, but it is not recommended unless you have the necessary experience and expertise. Improper installation can lead to serious problems and costly repairs.
