Imagine the following scenario: I live in an apartment and I am noticing signs of infiltration in my roof. The problem is that the infiltration is coming from the neighbor’s apartment. Can I do roof waterproofing underneath to solve the problem?
This is a very common situation in several apartments and houses throughout the national territory.
And, they almost always involve other problems such as having to deal with the neighbor or arguing with the condominium administration or waterproofing Services Company about who should be responsible for the damage.
The answer to the question is: The roof leakage waterproofing from below is most recommended solution.
And in this text we will explain why underneath roof leakage treatment is not a solution, going through the details and technical explanations, and also explaining what the best seepage control practices are to solve problems of infiltration of the roof from the upper floor.
Identify the source of the infiltration to solve roof waterproofing
The classic signs of infiltration in roofs and waterproofing problems are well known. They are mold, stains, peeling paint, bad smell and leaks.
In addition to signs that are not easily visible, but may be happening, such as exposure of concrete reinforcement, carbonation, leaching and cracking.
Understand that the infiltration happens due to structural damages. The structural elements of reinforced concrete are capable of guaranteeing roof insulation. However, they are not waterproof materials. It is therefore necessary to carry out some type of waterproofing services in Islamabad, according to the requirements.
In this sense, when there are signs of water infiltration on a roof, it is necessary to identify whether:
1. Infiltration is due to roof waterproofing failures
The asphalt blanket that is used in the waterproofing services in Lahore has a useful 5-10 years life offered by Roof Powers.
This means that eventually the heat proofing needs to undergo maintenance.
As the blanket cannot be exposed, you will need to solve this pathology by removing the entire floor. Then you will redo the asphalt blanket.
2. Infiltration is due to leaks from hydrosanitary systems
You may have some type of piping and connection (siphon box, cold water piping or downpipes etc.) leaks.
In the most modern buildings, the pipes are in a visible manner. They have no easier access, without the need to break the concrete structure for repairs.
This problem can happen in basement waterproofing, roof garden waterproofing, foundation waterproofing wall waterproofing, underground water tank waterproofing and bathroom and tiles waterproofing.
Positive hydrostatic pressure x Negative hydrostatic pressure
A very important concept to understand is positive and negative (hydrostatic) water pressure.
Understanding this concept is essential to correctly choose the type of Roof Waterproofing Company in Pakistan. What type of the techniques you should apply in order to guarantee a safe and long-term warehouse waterproofing service.
When water exerts pressure in the direction of waterproofing, it is a POSITIVE HYDROSTATIC PRESSURE.
When water exerts pressure in the opposite direction of waterproofing, it is NEGATIVE HYDROSTATIC PRESSURE.
You can understand the positive pressure as that which “pushes” the structure from the inside to the outside, or from the top to the bottom. It can happen in swimming pool waterproofing and commercial overhead water tank waterproofing.
