How to Find the Right Home Waterproofing Plan

Updated 1/1/2021

Developing a home waterproofing plan after your basement floods is like securing the gate after your dog gets out and chases the neighbor’s chickens.  Both of these situations are stressful, frustrating, and can be very costly (assuming your dog is more effective at hunting than mine).  

Even if you only use your basement for utilities and storage, flooding can do serious damage.  Laundry and HVAC units aren’t designed to be submerged.  And if you’ve stored heirlooms or irreplaceable items with sentimental value?  Well, there’s bound to be some grief involved.  

There are environmental cues that indicate you need to be very proactive about waterproofing, but even the best-situated home can flood if the circumstances are right.  Acculevel has been helping homeowners waterproof their basements and crawl spaces since their founding in 1996.  We want to help you avoid water damage whenever possible, to protect your home and belongings.

In this article, we’re going to describe steps you can take on your own, what signs suggest you need professional waterproofing, and give you the resources to be better informed and prepared.  


Prevent Water Intrusion

The first two are measures you can take yourself, if you are a DIY sort of person.  They are both aimed at keeping water away from your foundation, where it is most likely to work its way into your basement or crawl space.


Contrary to what most of us think, the ground around a home should not be level.  It should slope gradually down-and-away from the house.  This is called grading, and it encourages rainwater to drain away from your home’s foundation.  It’s not a guarantee against water seepage, but it’s a great starting point.



Evaluate the guttering around your home (and garage, if you have one).  Make certain they are in good condition, clear of any obstructions, and are securely fastened.  The downspouts should be aimed away from your home’s foundation; we strongly recommend that the downspouts empty at least 10 feel from your house.  If you’re not familiar with this project, we have a step-by-step downspout extension tutorial here.


Close the Basement Drain

If your basement has a drain set into the floor, please have it adjusted by a quality plumber.  A professional can install what is called a backwater valve in the floor drain.  This valve ensures the drain can only work in one direction (out!).  This will prevent anything, including sewage, from flowing into the home.

Signs You May Need a Waterproofing System Installed

Obviously, if you have water leaking into your basement or standing water in your crawl space, you need waterproofing.  But there are other, less obvious, environmental cues that indicate your home needs protection against water intrusion.  

A waterproofing system requires two major components:  water drainage and a sump pump.  The type of drainage system will vary, depending on the kind of basement floor you have. If you have a crawl space with a dirt floor, you should also have a vapor barrier installed.  

If you don’t have any water intrusion, but you do have the musty smells that indicate moisture is a present and problematic, you should consider installing a whole house dehumidifier.  A good quality dehumidifier will do more than reduce the humidity in your home; it will have a significant impact on your air quality and health.

Chart for humidity levels

A study performed by the American Society of Heating, Refrigerating and Air-conditioning Engineers determined that the ideal humidity level is around 50%.  This is the best condition for your home, and the least likely to produce bacteria, virus, fungi, or other irritants.
