When Is Exterior Basement Waterproofing Necessary?
When it comes to a homeowner’s worst nightmare, having their basement flood is near the top of the list. Besides being messy and inconvenient, a basement flood can cause significant damage – and extensive repair costs.
One of the best ways to prevent a flood from happening is by completing exterior basement waterproofing. Here’s what you should know about this process and how it can help prevent a disaster from happening in the first place.
Exterior Basement Waterproofing and Foundation Repair
Whether you have seepage or dampness occurring through your basement walls, exterior foundation waterproofing is a great solution.
The process involves applying an application of a quality multi-layer foundation seal. The protection is multi-layer, consisting of hydraulic cement, Portland cement, self-adhesive elastomeric membrane, and dimpled Delta-MS membrane. It spans from grade level down to the foundation footing or somewhere deeper than the basement floor.
The end result eliminates the opportunity for water and moisture to permeate through the basement walls – something that’s not possible with an interior de-watering method.
When To Consider Basement Waterproofing
If possible, you should waterproof the exterior walls of your basement when building your home. If your house is older and you are unsure if the external walls have been treated with external waterproofing, here are some signs to consider:
Staining on the basement floors or walls is an indication of water damage. One of these causes is groundwater seeping through basement wall cracks – and should be addressed immediately.
Smelling a distinct musty, damp odour as you enter your basement is often caused by higher humidity levels. When a basement is wet, mould and mildew can grow and create this strong smell. This can create health problems such as respiratory issues, so address this immediately. If not, mould can produce airborne spores that can circulate throughout your home via your central heat and air system.
If you notice a sparkling light effect sometimes when looking at bare floors or walls in your basement area, pay attention. Usually, you’ll also notice powdery white staining on walls.
Mineral deposits from moisture evaporation form on the concrete and cause the sparkling effect, whereas the powdery stain is due to a cement mix breakdown in the walls and floor. Both indicate a moisture problem, which should be investigated right away.
Damage to Store Items
High humidity levels accompanying wet basements can make a disaster out of stored clothing, linens, wood furniture, and whatever else you’re keeping in this space. Noticing puddling water or damp items is an indication that a more significant waterproofing issue is at play.
