Basement waterproofing costs an average of $5.50 to $8.50 per square foot, with more thorough waterproofing methods ranging from $7 to $11 per square foot. Pricing can be considerably different from one aspect of waterproofing to the next, depending on the extent of the leak. For example, do you need to excavate, or waterproof both the interior and exterior, or install extras such as a sump pump, or all?
Exterior Basement Waterproofing Cost
The average cost of waterproofing your basement from the outside with a coating or membrane is $5 to $8 per square foot, which typically includes materials and labor costs. The liquid or sheet membrane keeps water from penetrating the basement walls.

Basements are typically damp proofed at an average cost of $5 to $8 per square foot which includes excavation. For more thorough waterproofing solutions, expect to spend $7 to $11 per square foot or more. Here’s the difference between each:
Cementitious Waterproofing
Cementitious waterproofing your basement costs $7.25 per square foot for the cement and professional labor. Cement waterproofing also works great for patching cracks or sealing a crawl space. A cement solution is a thick, durable coating that is easy to apply, provides a smooth look, and can be painted on.
A significant drawback of using a cementitious solution is that the cement is not flexible and no give to it. If there is any joint movement or cracking, then it won’t be as effective. However, it will stand up just fine to water exposure and is typically used in dry climates.
One gallon of cementitious liquid solution costs about $39 and covers up to 150 square feet. An acrylic additive will make the mix longer lasting and bond better. You’ll have to buy this separately. Two coats are preferable on most surfaces for waterproofing purposes.
Foundation Waterproofing Membrane
A more costly solution than a cementitious coating is a waterproofing membrane; however, it will be much more powerful. Installation of a membrane requires excavating and adding drainage panels to block the water from seeping in completely. A liquid membrane is more effective because there are no seams between panels that could leak.
