Elevator pits, which are the lowest point of buildings, become the target of groundwater if their exterior insulation is not done properly. Water filling the pit causes great damage to elevator mechanisms and poses a safety risk.
In these cases where external excavation is impossible, the Polyurethane Injection System (Negative Side Insulation) comes into play. IZZOBOSS experts permanently stop the water flow in seconds by injecting high-pressure polyurethane from the inside into the concrete cracks where the water comes from.
