Waterproofing elevator pits for families, apartment buildings or high-rise housing, offices, and hotels is a necessary job because elevator pits are often located in the lowest position of the building such as the basement. susceptible to seepage from underground water sources.
The construction of waterproofing the elevator pit needs to be carried out as soon as construction begins because otherwise, water will seep in, causing damage to the engine and machinery.
Waterproofing of elevator pits requires high and stable techniques because in addition to normal waterproofing, it is necessary to take into account the vibration of the machine and motor, so that the structure and durability of the pit can be guaranteed. Castle.
Causes of elevator pits being waterlogged:
Do not install the elevator pit waterproofing system from the first phase of the project.
The existing waterproofing system may have been improperly constructed, used incorrect methods, or damaged during construction.
The elevator shaft may be too old to accommodate an effective original waterproofing system.
Adjacent construction may have changed groundwater levels or directed water flow.
Nearby water pipes may burst, or the drainage system may block groundwater pressure, increasing the risk of water seeping into the elevator shaft.
Times of the year, especially the rainy season, can cause sudden increases in groundwater levels, increasing pressure and water infiltration.
The use of poor quality waterproofing materials can be an important cause of failure in the water penetration prevention process.
The importance of waterproofing elevator pits:
The elevator pit, located at the bottom of the elevator shaft, plays an important role in the elevator system. This creates the need to thoroughly treat elevator pit seepage, and below are the main reasons:
Designing the elevator pit in a negative position relative to the ground creates favorable conditions for leaks due to underground water and cracked water pipes.
Elevator pits have a high risk of leaking, affecting both the construction and the normal operation of the elevator.
Waterproofing the elevator pit is an extremely necessary measure to ensure the system is best protected against leaks and unforeseen effects.
Leakage can lead to unnecessary risks during elevator operation and pose a safety risk to users.
Elevator pit seepage treatment needs to be done right from the construction stage to ensure maximum efficiency and safety for the system.
Waterproofing the elevator pit is not only a preventative measure but also a protection for the engine. And the elevator system from the negative effects of the surrounding environment.
Instructions on the elevator pit waterproofing process with each appropriate material:
Waterproofing elevator pits is an important method in construction and building maintenance to prevent water intrusion into this area. Below are the steps to effectively treat elevator pit seepage:
Step 1: Prepare waterproof surface:
- To ensure optimal waterproofing performance, surface preparation of the elevator pit is important and is carried out according to the detailed steps below:
- Make sure the floor and wall surfaces of the elevator pit are solid and do not have large cracks, crow's feet, or foreign materials sticking to them.
- Clean the surface from dirt, impurities, and excess grout by chiseling away unwanted spots.
- Inject specialized glue into cracks and crow's feet to ensure a strongly bonded surface.
- Use a floor sander to create roughness for the surface, increasing the adhesion of waterproofing materials.
- Inject glue or waterproofing material into the cracks to ensure they do not reduce waterproofing performance.
- Ensure that the prepared surface has good adhesion to the waterproofing material, helping to achieve thorough waterproofing results.
Step 2: Waterproofing treatment:
- After the elevator pit surface has been carefully prepared, the next step is the waterproofing treatment process, to ensure the waterproofing layer is effective and durable. Below are the detailed steps:
- Start the waterproofing process from outside the elevator pit, ensuring even waterproofing on both floor and wall surfaces.
- If required or specific conditions, apply additional waterproofing layer from inside the elevator pit to enhance waterproofing.
- Check the thickness of the waterproofing layer to ensure uniform coverage over the entire pit surface.
- Best technical treatment for solid areas, corner lines, or special locations to ensure there are no weak spots in the waterproofing system.
- Using advanced waterproofing technology such as self-adhesive waterproofing membranes and penetrating waterproofing agents, to achieve high efficiency and long-term protection.
- Allow the waterproofing layer time to cure and completely combine with the surface of the elevator pit, helping to create a strong waterproofing layer.
This waterproofing treatment process plays an important role in protecting the elevator pit from the impact of water and ensuring the safe and effective operation of the elevator for a long time.
