How much does it cost to waterproof a basement from the outside?

Is it better to waterproof basement from inside or outside?

Exterior waterproofing is also more expensive than interior waterproofing, because it requires more work and more material, but it efficiently stops water from getting close to the foundation of your home.
What is the best basement waterproofing method?
Waterproofing a foundation from the outside typically involves using polymers and membranes to coat the exterior of the walls, installing a trench drain underground, or a combination of both methods. When done properly, exterior drainage is generally considered to be the most effective way to waterproof a basement.
Does insurance cover basement waterproofing?

Can you seal a basement from the inside?

Does sealing a basement floor reduce radon?
Sealing the basement floor can help reduce the amount of radon entering the home. But just sealing the cracks would be unlikely to reduce those amounts in the long term. Sealing all cracks and applying non-porous, thick epoxy coatings (over 10 MILS dry film thickness) would be a better step.
Will a French drain prevent water in basement?
In fact, it keeps the basement dry by preventing the water from developing the pressure it takes to enter the basement in the first place. A French drain, often called “drain tile,” installed inside or outside the foundation, will keep most basements dry and never requires maintenance or replacement.
