Changes To Your Home Can Bring Changes To Existing Waterproofing
Waterproofing in basement walls is a crucial part of keeping your house safe from mold and rot when you live in a region with high water tables. You need other help, such as from sump pumps, but the moisture barriers that you add will also help when the moisture in question is in the form of humidity. But the waterproofing is only as good as the integrity of the wall. You could have the best waterproofing done on your home, only to find the layer has been breached because you made changes to your home and didn't account for the waterproofing. If you make any changes, you have to have the waterproofing checked and possibly modified for continued protection of your home.
New Intrusions From Staples and Nails
Whether you're replacing carpet or installing heavy picture hangers, be sure you know which walls were waterproofed and how they were waterproofed. Sometimes the waterproofing is a physical barrier inside the wall, in which case something like new carpet staples likely will not affect it. But other times the waterproofing is a chemical layer added to the two sides of each wall, in which case carpet staples, nails, those plastic brackets that add strength when you hang something away from a wall stud -- they could all pierce one of the layers and weaken your waterproofing protection.
This is not to say that you can never hang pictures in your basement. Just be aware of where the waterproofing is and what type of waterproofing it is. If you want to make an intrusive change to a section where there is waterproofing, you need to have a waterproofing company like Stan Young Drainage inspect the area or add more waterproofing.
Major changes like additions should set off a waterproofing alarm, but sometimes people forget. If you excavate to expand the basement and add new walls, your contractor should add waterproofing. If you're not sure if he or she did, call a waterproofing contractor to inspect and possibly get the job done right.
Waterproofing is not a joke. Without it, you risk rotting wall studs, mildewed drywall, and moldy carpet. Not to mention the air quality in the basement would take a dive from all the humidity and spores. And when you have waterproofing added, ask the contractors what sorts of changes you can make to the wall, and where, to avoid breaching the waterproof layer.
