Sealing the elevator pit

The elevator shaft is located at the lowest part of the structure, which makes it very important. In mountainous and high-rainfall areas, groundwater and qanats can infiltrate the shaft, leading to water accumulation, which causes rusting of the elevator equipment. Additionally, the proximity of water to electrical currents can result in serious and irreparable damage.

Frequently Asked Questions

No, because before applying the sealant and resin Z90, the surface must be completely dry. For this reason, we block negative water flow with the instant-setting powder MA700 and control negative moisture with the crystallizing powder SQ2000

No, because these two powders temporarily dry the elevator pit surface so that we can apply the main insulation sealant and Z90 resin.

No, the Z90 sealant and resin are resistant to both negative and positive pressure.

Due to the fact that the pit is located at the lowest level of the building and is in proximity to groundwater or rain-prone areas or mountainous regions where the water table is high, it leads to the accumulation of water in the pit, which enters the structure in the form of holes or pinholes.
