Why is my elevator shaft leaking?
There are many reasons why water might start to enter an elevator pit. Here are some common issues we encounter:
- Nearby construction has changed or redirected the local water level.
- The current waterproofing system was incorrectly installed, or it was damaged during the building’s construction.
- When the building was built, the building code did not require a waterproofing system.
- Nearby water main has burst, been damaged, or become blocked.
- There has been a higher amount of rain recently.
Where is this leak coming from?
The short answer is, probably from a joint or cracks in the wall, but not necessarily.
If the elevator pit is made from poured concrete walls, there will be a construction joint or kicker joint. This joint is weaker than the rest of the wall, and over time groundwater might seep in through that joint. Sometimes there might be other imperfections or cracks in the concrete walls or base, making it possible for water to enter these areas also.
Some elevator shafts are constructed with traditional bricks or concrete blocks. Once again, water could enter through any weak points in the brick or block joints. The joints between the floor and the wall can be commonplace for water to come in.
On newer buildings, it’s common for an elevator shaft to be formed from mass poured concrete (often as part of the foundation) and then a concrete block or bricklayer built inside it. If water makes its way through both of those layers, the leak point can be more difficult to find and to seal. However, Star Lift is experienced at even these types of repairs, and we simply use different methods to accomplish the same goal. In the end, you will regain that lost confident feeling you once had and stand pleased to see your elevator pit completely dry!
