Understanding the Role of Sump Pumps in Basement Waterproofing

By Haris

Sump pumps are an important component of basement waterproofing systems. They work by removing water that has accumulated in a sump pit and directing it away from the foundation of your home. In this article, we’ll explore the role of sump pumps in basement waterproofing and how they can help protect your home from water damage.

What is a Sump Pump?

A sump pump is a device that is typically installed in a basement or crawl space. It is designed to remove excess water that has accumulated in a sump pit. The sump pit is usually dug into the lowest point of the basement or crawl space and serves as a collection point for water that has entered the space through cracks in the foundation, groundwater infiltration, or other sources.

How Sump Pumps Work

When water fills the sump pit to a certain level, a float switch activates the sump pump. The pump then removes the water through a discharge pipe and directs it away from the foundation of your home. This prevents the water from seeping into the basement or crawl space and causing damage.

Types of Sump Pumps

There are two main types of sump pumps: pedestal and submersible. Pedestal pumps have a motor that sits on a pedestal above the sump pit, while the impeller is located at the base of the pit. Submersible pumps, on the other hand, are completely submerged in the sump pit and have both the motor and impeller located in the same housing.

Choosing the Right Sump Pump

Choosing the right sump pump for your basement waterproofing system is crucial to ensure it is effective in removing water. The size of the sump pump should be based on the amount of water that needs to be removed and the size of the sump pit. It’s also important to consider the type of pump, as well as its power and capacity.

Maintaining Your Sump Pump

Regular maintenance is essential to ensure that your sump pump continues to function properly. This includes cleaning the sump pit, checking the float switch, testing the pump, and inspecting the discharge pipe for any blockages or damage. It’s also important to have a backup sump pump installed in case of a power outage or mechanical failure.


Sump pumps play an important role in basement waterproofing by removing excess water from the sump pit and directing it away from the foundation of your home. Choosing the right sump pump and regularly maintaining it can help ensure that your basement remains dry and protected from water damage. If you’re considering a basement waterproofing system or have any questions about sump pumps, it’s best to consult with a professional basement waterproofing contractor.
