Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage. 

A sewage ejector pump is necessary if you have any plumbing fixtures, such as a bathroom, laundry room, or sink, located below the level of your home's main sewer line. Standard plumbing relies on gravity to move wastewater and solid waste to the municipal sewer or septic tank. However, for fixtures located below grade (e.g., in a basement), gravity is not sufficient.

The purpose of a sewage ejector pump is to actively pump this wastewater and solid waste upward into the main sewer line. Without an ejector pump in this situation, wastewater would have no way to exit and would eventually back up, causing a sewage overflow or flooding in your basement. If all of your home's plumbing is on the main floor or higher, gravity can handle the drainage, and an ejector pump is not needed.

Yes, it’s possible to install a sewage ejector pump outside rather than in a basement. However, there may be some extra steps involved, including running pipes from the inside to the outside of your home and digging (and re-filling) a hole for the basin. If you aren’t comfortable with this type of work, contact a plumbing pro to handle it for you.
