What to think about to avoid water damage in your outdoor concrete structures
Concrete is a common material for many outdoor structures in many homes. Concrete is a durable material that can withstand force and that can last over a long time. However, one negative aspect of concrete when it's being used for outdoor purposes is that it doesn't withstand moisture very well. If concrete gets cracked and moisture penetrates the structure, the whole structure might be ruined. Moisture can affect the iron mesh inside the concrete and cause further cracking, or the concrete itself can absorb the moisture, become porous and start to break apart. To protect your concrete outdoor structures, you need to know what needs to be done in order to perform basic waterproofing repairs.
Examining for cracks
Cracks are the main reasons to why a concrete structure needs to have waterproofing done. This is where the moisture gets an entrance into the concrete. In some instances, like when you want to have roof waterproofing done because your roof has sprung a leak, cracks are clearly visible as they are leaking water into your house. However, when you're examining, for example, a balcony for cracks, they might not be as visible. Make sure you examine all places where other materials are penetrating the concrete, like rails or screws, as these places are likely places for cracks to form.
Filling the cracks
The first step to waterproofing any concrete structure, like waterproofing a balcony or deck waterproofing is to fill the cracks. You might want to hire waterproofing contractors to do this, but if you are confident and have some experience, it can be done by yourself as well. Inject the cracks with the filler material and make no part of the crack is still open on the surface when you're done.
After you've filled all cracks, you need to seal the surface. Sealant is what makes the concrete waterproof and you should use it regularly to ensure a long lasting result. Remember that you should seal the entire surface that you want waterproof, and not just the part where the initial problem has started. You can seal the area where the healed crack is located more than once, but don't just focus on that area. Spread the sealant evenly over the entire area and let it dry properly. Sealants also enhance colour and shine of the surfaces, which will make your structures look even better. For sealing a concrete roof, you should call waterproofing contractors to do it for you, as it's a dangerous working environment where you can injure yourself severely if you were to fall.
