Waterproofing Steps For Older Buildings
Damp issues in older buildings can be tricky to solve. Old buildings need to maintain vapor permeability, and you need to use a waterproofing method that allows the walls to breathe. Waterproofing is very critical in older buildings, and it is by no means an easy feat.
You see, modern buildings are constructed in a way that they keep water and moisture out by using impervious materials, airtight design methods, and cavity walls. This means that very little moisture or water goes through the building materials. On the other hand, older buildings were constructed using stone or brick walls together with porous or weaker materials than used today. This means that moisture or water moves freely in old buildings. Here are steps to take when applying home waterproofing to an old building.
Determine if the Concrete Needs Waterproofing
If you feel that your house needs waterproofing, you can consult a professional contractor to give you some advice. They might suggest that you apply a liquid membrane or you fill up some cracks and joints. Once you determine what method to use, prepare your walls. You can caulk, patch with concrete patches or grind to smoothen the rough patches of the concrete. Once done, clean the area and let it dry before you waterproof it.
Choosing the Right Waterproofing
You can use a liquid membrane, which will be quick and economical and easy if you follow the instructions. Liquid membranes, however, do not provide even coverage and it is hard to apply it consistently. You could also go with a self-adhering sheet membrane that you will peel and place on the concrete. These membranes are great but more expensive, and you need to be very careful with the sticky side because removing it is almost impossible. You can choose cementitious home waterproofing material that easy to apply. It is effective but dry up and might crack after some time.
Know What Walls Need Waterproofing
You should know what walls need waterproofing and what walls do not because this will save you time and money. You should waterproof walls with soil on one side and a habitable space on the other. However, if you live in a wet region, you should waterproof all walls just in case. Make sure you follow all the directions when applying the waterproofing, so you don't cause more harm than good.
Conclusion
Once you are done, you should hire a home waterproofing contractor to check out your drainage system. Waterproofing your house will not help much if water does not drain efficiently.
