4 Methods Of Internal Basement Waterproofing

Are you looking to refinish your basement in the future, but want to make sure that it is properly waterproofed first? While there are many different ways to get this job done, exterior waterproofing may not be an option for you. This could be due to the cost of digging up around your home or simply not wanting to ruin your existing landscaping. That is why you will want to know more about the following methods for internal basement waterproofing. 

Drainage System 

If you have water coming in from around the home's perimeter that you want to get rid of, the best option may be to install an interior drainage system. This involves some excavating around the interior of the home's basement to install pipes that will collect the water and divert it out of the basement. This can do a great job and ensure the basement stays dry, though the installation process is costly and can be a bit messy.

Sump Pump

You also have the option of installing a sump pump. It works by collecting the groundwater so that it collects in the sump before it reaches your foundation. When the water level in the sump reaches a specific height, a float is activated that turns on a pump that empties the water inside. This water is typically diverted to a nearby drain so that the water goes to the local sewer system. 

Vapor Barriers

If you have condensation getting into the basement through the foundation walls, the best method to use may be a vapor barrier. This method involves installing polyethylene sheeting around the foundation walls to create a physical barrier that moisture cannot get through. This waterproofing method is not going to protect your basement from water that seems in through the floor due to static pressure, but it can offer some protection at an affordable price. 


If you have notable cracks along the basement foundation it may be worth using sealants. Sealants are placed within those cracks so that water can no longer get in through the weak point. While sealants are great at preventing water from getting in through exposed walls, they may not be great for walls that you are covering up with drywall. This is because the sealants can fail over time, which will result in water getting into your basement in a place where you cannot see or fix it.
