learn more about what is really happening beneath your home!

Inadequate Drainage & Improper Installation

All interior or exterior drainage systems must be properly functioning to prevent moisture from seeping into your basement. Professional drainage systems will ensure that water can move away from the house efficiently.

Inadequate Grading / Poor Sloping

Unsightly grading can also cause water to seep into your basement. If the soil around your foundation isn't sloped away from your house, water will pool against the wall and cause flooding. Moreover, improperly compacted fill dirt will cause water to flow toward your home's foundation.

Defective Gutter & Downspout System

A defective gutter or clogged downspout system can be a cause of a wet basement. If your gutters are too small, the downspout could be too close to the foundation, causing water to seep into the basement. You should have at least one downspout per 50 feet to ensure adequate drainage.

Excessive Condensation

Condensation is the result of cool basement walls meeting warm moist air. A common issue in most basements, it will make your basement clammy and cause wood to rot. It can also encourages a humid environment that promotes pest infestations.

Do you feel damp in your basement or hear dripping but cannot identify the source of any leaking? Has your floor presented with cracking that looks troublesome? Answering yes to questions like these can signal a need for professional basement waterproofing services.

Foundation Crack Damage Repair

Concrete Cracking

If there are cracks present, and they are large or have a ragged appearance, the problem may be rooted in the foundation. If the cracks extend into the walls or the ceiling, this could be a sign that the foundation is weakened. Professional evaluation is recommended.

Dry Rot

High humidity and leaks around supply lines can create the perfect environment for wood rot fungi. A musty smell may indicate that you have wood rot. The odor will increase in strength and intensity as it spreads throughout the house. 

Mold Growth

Some common signs of a wet basement are black or green mold, discoloration, or a musty smell. If you see clusters of mold growing, you may need a professional to help identify the severity of your mold infestation. Mold symptoms can also be the result of ceiling leaks.

While we highly recommend an Exterior Waterproofing system that creates an impenetrable barrier around your foundation, an Interior Waterproofing system will also do the job to keep water off your home’s important structures. Simply put, the most effective method is to seal the foundation on the outside, while getting water off the foundation as quickly as you can.

Unlike an exterior system, an interior system allows water to pass through to the foundation and collect in a series of drains where it is pumped outside the home. Of course, if nothing is done about intruding water, you are going to be left with a deteriorated foundation that will cost a lot of money to fix.

Unlike interior waterproofing, this process involves digging around your house to the base of the foundation walls. Next, a waterproof coating is applied to the foundation walls and finished with drainage panels. Once the coating is dry, drainage panels are installed to carry water away from the house. Exterior waterproofing usually requires a professional contractor for completing the project accurately and efficiently.

In the event that your home doesn’t have a proper drain system, you should consider installing an interior drainage system. This system collects water from below the footing and channels it to a sump pump. An interior drainage system is installed on the inside of your basement wall or footing, reducing mess and expense. Then, a new sump pump will be installed. 

Interior waterproofing in your basement is often the corrective solution after water has already entered the house. Exterior waterproofing, in contrast, is more of a preventative measure for keeping your basement dry and protected.

An internal system is designed to keep water out of your home and away from your foundation. This includes digging a trough that collects water and directs it to a sump pump unit, also known as a French drain.

The installation of an internal drain tile around the perimeter of the foundation is most often done after the construction of the house. This is because they are usually installed in response to a damp basement or sometimes just before finishing a basement remodel. An exterior waterproofing installation is more extensive. These systems are installed outside the foundation to prevent water from entering the basement in the first place, not in response to it.

This process requires excavation around the house to expose the foundation so that a durable waterproof sealant can be applied. Although more extensive than interior waterproofing systems, this type of waterproofing is most effective and preventative.

Waterproofing is a complex operation that should not be tried as a do-it-yourself project. Instead, it is recommended to employ a professional waterproofing company to guarantee the job is done safely & correctly. It takes a lot of talent, and a professional company will hire bonded and licensed workers with a lot of experience.

Most basically, one of the leading causes of basement intrusion is caused by leaking. However, leaking can be repaired in a number of ways. Keep in mind that not all solutions you choose will do the job of solving the problem! Considering which one you decide to go with, you could experience a disappointing outcome that ends up causing you to have to repeat the whole workload again soon.

Quick-fixes, like basement moisture absorbers for example, work only to temporarily relieve the effects the problem presents at its face and for a short amount of time. As the absorbers draw moisture from the air, the air will most likely become less damp. This relief will only last as long as the time it takes before you need to replace the product again. It is inevitable that the dampness will return once the absorber is removed due to the fact that the moisture is not being prevented from entering the basement at the source.

Basement Waterproofing should be considered a lot the same way as other services designed to improve your home. Here are some of the pros and cons of Exterior Waterproofing.


  • It will reduce the wall cracks and water leaking into your basement. A professional exterior waterproofing system is made of components that effectively seal the foundation wall to prevent water from seeping in.
  • It will call for all installation processes to happen outside the basement of the home, avoiding disruption of any basement living spaces.


  • High humidity may require more measures than an exterior waterproofing system alone. Water will no longer enter your basement or crawl space through foundation walls or up through the floor, however, high humidity in the air can still make for conditions that can cause mold growth.
  • Installation for exterior systems is much more labor-intensive and time-consuming than interior waterproofing systems, yet the results yield a much more efficient outcome!
