For elevators… That are tested!
Just imagine the face of those present when Elisha Otis, a smart American entrepreneur, presented the first elevator in 1853. It was enlightening! During an exhibition at Crystal Palace in New York, visitors were shown how the enclosure works, which was fitted with an automatic safety device for blocking it in the event of an emergency.
Today, however, we are used to using elevators and we often complain if they are out of order and we have to go back to the old-fashioned habit of using the stairs!
But what does building an elevator involve?
Elevator pits are structures located at a lower level than the internal standing area and must be able to withstand both static and dynamic loads. In short, they need to not only support the weight of your Saturday shopping but also take it up to the fifth floor!
Many problems may be encountered when an elevator is being installed. First of all, there is the danger of infiltration and all the consequences it may bring. Then we mustn’t underestimate the fact that, in the case of a hydraulic elevator, oil may leak from the system, which is why electric elevators are always recommended. TeMa has developed the T-Kone family: HDPE honeycomb membranes that provide mechanical protection, damp proofing and drainage. As far as drainage is concerned, the research and development centre that TeMa relies on has developed drainage geocomposites that filter, protect and drain the system.
Waterproofing? Yes, but how
It is not enough to install membranes that perform a drainage function, it is also necessary to make spaces waterproof. But how? By using bentonite geocomposites that self-bond to concrete, such as T-Bentostop F and T-Bentostop F XL. They are made of a non-woven fabric and a polypropylene fabric with a layer of natural sodium bentonite in between.
These are the essential aspects that should never be underestimated for excellent, high-performance implementation. We must always remember that a thorough preventive analysis of the dangers, along with accurate and responsible installation, are the best techniques for avoiding problems and inconveniences caused by infiltration in the future.
