Basement waterproofing has become increasingly popular as homeowners have sought to convert tough basement space into living space. Waterproofing methods and approaches can be grouped into two major classes: Internal and External. In this article, we’ll explore the popular methods and techniques for waterproofing basement walls.
Why waterproof your basement walls ? Is not it true that internal waterproofing is much more popular and more economical? Well generally speaking, yes. Internal methods are very popular and several can be extremely affordable. However, only speaking internal basement waterproofing is not really waterproofing at all because you’re not preventing water from entering the basement walls. Rather, you’re devising methods of addressing the water after it does input. On the flip side, when you waterproof your basement walls you are actually preventing water from entering them in the first location. This is significant since water is naturally destructive to construction materials. Over time constant water vulnerability breaks down the composition of any substance even the mortar and block of that most base walls are constructed.
So what could be done to the exterior of your cellar walls? Well, exterior basement waterproofing actually boils down to two types of strategies: drainage and barriers. There’s also a third strategy known as diversion which can be thought of as a adjunct to drainage. Drainage means you are installing methods to drain water from the ground surrounding the basement. Considering that water follows the path of least resistance, you are giving the water an easier path to follow than to enter your foundation walls. Diversion systems refer to the rain gutters and downspouts in your house. These systems are made to divert this rainwater away from the floor surrounding the base and therefore not put any undue burden on the drainage system. Barrier systems involve employing a waterproof coating on the outside surface of the foundation walls. This way the little amount of ground moisture in touch with your basement walls will still not enter since it can’t penetrate the waterproof barrier. Each one of the products, apparatus, and techniques available for external basement waterproofing fall into these 3 categories. What’s more, they are all more successful if used in concert together.

Both drainage and barrier methods have something in common. They both require substantial excavation around the structure to expose the basement walls. This excavation represents the majority of the cost of outside waterproofing and is most likely the biggest reason most homeowners elect for interior options. Excavation is not only costly but it is disruptive and insecure. An inexperienced operator may actually damage your base walls using an excavator. Excessive excavation at any one point can cause shifts on your walls. Finally, there’s always a possibility that excavation can damage an underground utility line that was either incorrectly marked or just not understand about. All of these possibilities can add substantially to the total cost of the undertaking. Despite the risks and costs related to outside waterproofing, the advantages may still make it a rewarding endeavor.
Exterior drainage systems are usually known as footer drains or tile drains. These systems are comprised of a station that is dug around the perimeter of the foundation walls in a depth just below the wall footer. The channel is full of an aggregate, in different words, gravel. In the center of the aggregate lies a pipe. The pipe has perforations that allow liquid water to enter. As groundwater descends it finds little if any immunity to entering the trench because of the prosperity of air spaces inside the gravel (aggregate). After in the trench, the water also easily enters the pipe through the perforations. The pipe then contributes to a remote drainage location such as a storm drain or a natural groundwater drainage route.
A good exterior footer drain system gains greatly from a good diversion system. As we mentioned previously, a recreation system is comprised of the rain gutters and spouts on a building. You might be asking yourself why you need to worry about the rainwater whenever you have an underground system draining water away from the residence. The main reason is that water carries silt and other particulate matter dissolved inside. Over time, that sediment accumulates inside the footer drains and begins to obstruct the circulation of water. The longer water flowing to the footer drains, the faster sediment will collect. A good diversion system will keep most rainwater out of the drainage system. This is accomplished with gutters accumulating water in the roof edges and downspouts emptying at least 5 feet away from the foundation walls on floor sloping away from your home. Ideally, the downspouts will drain into underground pipes emptying into storm drains. The longer rainwater is diverted away from the footer drainage system the longer the machine will survive.
Eventually, the barrier systems are watertight layers applied to the outside surface of the foundation walls. When the floor is excavated to expose the wall surfaces any residue of dirt is removed to get a clean application. The barrier material, which is frequently known as a sealant, is generally based on rubber or a polymer. Some goods are in fact a cement or asphalt and applied as such. The latest commercially available products are quite versatile. They’re lean enough to be implemented with sprayers which greatly reduces the labor required nevertheless they’re also durable enough and powerful enough that after completely cured many are justified to last 10 years or more with the appropriate application.
External recreation, drainage and barrier systems working in concert are remarkably capable of waterproofing basement walls. While external systems can be costly and many are set up in the time of building construction, a properly designed system set up at any given point in a building’s lifecycle can provide comfy, water-free basement dwelling for many years. https://bluemaxxbasements.ca/waterproofing/exterior
