If you are in the process of building your house, then you should find out about the right waterproofing techniques that would protect your house from the vagaries of nature for many years to come. These waterproofing measures would help you remain cozy and comfortable for several years. You should be aware that joints, cracks, openings in the windows and doors are the most vulnerable to dampening and damage in the due course of time. Here we will discuss the procedure for concrete waterproofing your house, which can protect your house from damage for several years.

#1. Determining whether your concrete house requires waterproofing: Pre-cast concrete panels, core-formed concrete, insulated concrete form walls are certainly more waterproof and they rarely require additional precautions for waterproofing. The pre-fabbed exterior concrete walls are often coated mainly for getting the desired appearance rather than waterproofing. In case you think that your concrete structure requires waterproofing, then you should book the services of a trust-worthy general contractor. The expert contractor would suggest whether it would be better to apply a liquid membrane, or it would be better to fill the joints or cracks.

#2. Preparing the walls for the coating: In case you have decided to go ahead with waterproofing, then you need to decide which of the following techniques you would want to adopt:

  • Concrete patching: This technique usually fills those joints which are wider than 0.6 cm. You need to make sure that the concrete patch has to be completely dry before you proceed.
  • Caulking: This process is used to fill the cracks and joints larger than 0.6 cm with using superior quality polyurethane caulking.
  • Grinding: This process is mainly used for smoothening any uneven or rough concrete surface in order to ensure that the slurry or the waterproofing membrane gets an even surface for adhering properly.

#3. Clean the concrete surface thoroughly before waterproofing for best results: It is mandatory that the concrete surface be cleaned thoroughly using a very stiff brush and some trisodium phosphate popularly referred to as TSP. Any dirt or loose material should be washed off the concrete’s surface. Most waterproofing membranes work better on clean and smooth concrete surfaces. You must dry the concrete surface before proceeding further.

#4. Choosing the walls for applying the right waterproofing: You should hire an expert contractor who would advise which walls that are to be necessarily waterproofed. If your habitable region is majorly a wet area, then you should waterproof all the walls. Also, you should extend the waterproofing to at least one foot from the waterproofing wall to the one which does not require waterproofing. This little buffer should be adapted to be extra cautious.

#5. Applying the finishing system as per the directions of the manufacturer: Depending on the waterproofing method adopted, the manufacturer usually has several best practices and suggestions. Keep those suggestions in mind to get the best results.

#6. Adopting the best roof sealer in case you have a cast instead of a concrete roof: There are several homes which usually have a cast instead of the usual concrete roofs. In such cases, roll roofing reinforced with fiber or roofing cement should be applied in order to make sure that there is no probable water intrusion.

#7. Making provisions for proper drainage for addition waterproofing safety: All specialized waterproofing techniques may fail if there is no proper drainage of water that falls on the waterproofed walls. Hence, you should hire an expert who can ensure that provision is made for draining of water from the walls or the roof. 

The above tips for waterproofing will give your concrete house a longer life and will ensure that you do not have to keep making repairs constantly. You will be able to live comfortably in your years for a number of years.
