Basement waterproofing is a big ordeal for most property owners, especially, if you reside at a place susceptible to heavy rains and snowfall. Experiencing damp and flooded basements is not uncommon because, being the lowest segment of any building, the moisture from the soil and underground water often moves upward through concrete pores. It happens due to capillary suction- a common phenomenon where the soil becomes moisture saturated beneath the footing and slab. Other factors, like lack of ventilation, leakage in walls and floors, condensation, defective or missing gutters and downspouts, improper drainage, sump pump problems, inadequate grading, and improper window well installation, are equally responsible.
Thus, the list of basement dampness cause is elaborate, requiring expert assistance from waterproofing contractors Brooklyn to aid comprehensive solutions. To ensure that your basement is adequately waterproofed you must get the pros at work instead of opting for DIY because the job is labor-intensive and possessing substantial knowledge and skills is obligatory.
However, if you are in a dilemma whether to choose exterior or interior waterproofing, it is indeed a baffling decision. Considering your budget, the scope of waterproofing, and the feasibility, we have chalked out a thorough guide to help you determine the ideal fix.

Exterior and Interior Basement Waterproofing: Key Differences
To understand the viability of both waterproofing methods on your property, let us begin by learning the difference. So, here it goes:
- Mode of Installation- An evident difference between the two is the place where they are installed. As the term suggests, exterior waterproofing is performed on the building’s external surface encompassing the perimeter. Whereas, interior basement waterproofing includes the inside walls, floors, and ceilings by a waterproofing specialist contractor.
- Sump Pump Necessity- Sump pump installation is necessary for almost all interior waterproofing of basements. It is to prevent water accumulation across the weeping tile network. You don’t need a sump pump only if the weeping tile network is affixed to a storm sewer. On the other hand, the requirement of a sump pump in exterior waterproofing depends on the water table level. If it is too high, you may need a sump pump to protect your foundation from pooling water. It improves the overall waterproofing results.
- Functionality- Lastly, the functionality of both techniques varies. Exterior waterproofing is designed to provide complete protection against water damage. It implies that when the external surface is fully water-resistant, it does not allow water penetration. However, interior waterproofing does not restrict water seepage entirely. But you can still keep the basement dry through weeping tiles and a waterproof membrane.
Therefore, each method proposes unique characteristics and to choose between the two, we need to dig deeper into the context.
Primary Considerations for Choosing Between Exterior and Interior Basement Waterproofing
You require considering the following factors while choosing between the two types of basement waterproofing methods:
- Degree of Water Protection- The foremost factor you must focus on before choosing leakage waterproofing services is to set your goal of attaining a moisture protection level. In other words, since both methods function differently, you have to decide whether you want a complete or partial waterproofing solution. Exterior waterproofing offers foolproof protection as the foundation is entirely watertight by setting up an impermeable membrane. Water cannot touch the foundation. But through interior waterproofing, you can only protect the internal surfaces, and there are fair chances of foundation wall damage through external cracks and holes.
- Project Invasiveness- As mentioned already, exterior waterproofing is invasive and requires excavating the perimeter of your property. But, there is no need for excavation in interior waterproofing until you are installing a sump pump and constructing trenches.
- Durability- If you want a more durable solution, exterior waterproofing is your best alternative. It does not demand regular maintenance to prolong its functionality. Meanwhile, interior waterproofing may sometimes fail if your sump pump stops working and there is a drainage problem.
- Purpose of Use- For long-term use of your basement intended for office space or bedroom, exterior waterproofing works better to keep it dry and fresh.
- Budget- Exterior waterproofing is more expensive than interior waterproofing, but it is all worth the results. You can enjoy improved longevity and functionality with minimum maintenance.
