Sump Pumps

A sump pump is a crucial component of any home waterproofing system. This section will help you understand what a sump pump is, the different types available, how they work, and the key features to consider when choosing one for your home.

What is a Sump Pump?

A sump pump is an electrically powered device designed to remove water that has accumulated in a sump basin, which is usually located in the basement or crawl space of your home. By pumping water out and away from your home, a sump pump prevents basement flooding and helps maintain a dry and healthy living environment.

Types of Sump Pumps

  • Submersible Sump Pumps: As the name suggests, these pumps are designed to be fully submerged in water. The motor is housed in a waterproof casing, making it durable and efficient. Submersible pumps tend to be quieter and have a longer lifespan, but they can be more expensive and challenging to repair.
  • Pedestal Sump Pumps: These pumps have an upright design, with the motor mounted on a pedestal above the water level. Pedestal pumps are typically less expensive and easier to maintain, but they can be noisier and less efficient than their submersible counterparts.

How Sump Pumps Work

A sump pump is activated when water in the sump basin reaches a certain level, usually with a float switch. Once activated, the pump starts to remove water from the basin, discharging it through a pipe that leads away from your home’s foundation. The pump continues to operate until the water level has dropped below the activation point, at which time it automatically shuts off.

Choosing Your Sump Pump

  • Pumping capacity: Choose a pump with sufficient capacity to handle the expected volume of water in your basement. Capacity is typically measured in gallons per hour (GPH) or gallons per minute (GPM).
  • Material: Pumps made from cast iron, stainless steel, or thermoplastic materials offer varying degrees of durability and corrosion resistance.
  • Backup system: A battery backup or water-powered backup system can provide added peace of mind in case of a power outage or pump failure.
  • Noise level: Submersible pumps are generally quieter, while pedestal pumps may produce more noise during operation.
  • Warranty: Look for a pump with a solid warranty to protect your investment.

Understanding the basics of sump pumps will help you make an informed decision when choosing the right one for your home’s specific needs.

French Drains

French drains are an essential part of a comprehensive home waterproofing system. In this section, we’ll explore what French drains are, the different types available, how they work, and the key factors to consider when installing one in your home.

What is a French drain?

A French drain is a drainage system that diverts water away from your home’s foundation using a sloped trench filled with gravel and a perforated pipe. By capturing and redirecting excess water, French drains help prevent water infiltration and alleviate hydrostatic pressure on your foundation walls.

Types of French drains

  • Interior French drains: Installed beneath your basement or crawl space floor, interior French drains collect water that seeps through foundation walls and direct it to a sump pump system, which then pumps the water out and away from your home. Interior French drains are typically used when exterior waterproofing measures have failed or are not feasible.
  • Exterior French drains: Also known as a footing drain, an exterior French drain is installed around the perimeter of your home’s foundation. This type of drain captures water before it can penetrate your foundation walls and directs it away from your home. Exterior French drains are usually installed during home construction but can be added later if needed.

How French drains work

A French drain consists of a trench that slopes away from your home, filled with gravel and a perforated pipe. Water seeps into the trench through the gravel, then enters the perforated pipe, which carries the water away from your foundation. The slope of the trench ensures that the water flows in the desired direction, preventing it from pooling near your home.

Choosing your French drain

  • Location: Determine whether an interior or exterior French drain is more suitable for your home’s specific needs.
  • Slope: Ensure the trench has an adequate slope to effectively direct water away from your home.
  • Depth: The depth of the trench should be determined based on factors such as soil type, groundwater levels, and the depth of your home’s foundation.
  • Drainage: Make sure the drain discharges the water at a safe distance from your home and in an area where it will not cause erosion or other issues.
  • Maintenance: Regular inspection and cleaning of your French drain will help ensure its long-term effectiveness.

Understanding the basics of French drains, you can make informed decisions about how best to incorporate this essential component into your home’s waterproofing strategy.
