The Risk of Lift Pit Water Leakage is Beyond Concrete Quality



Leaking Lift pits and Lift Shafts in commercial and residential buildings – A common occurrence


Facility managers and property managers are entrusted with maintaining the quality, functionality, and safety of the buildings under their care. Amidst the numerous aspects demanding their attention are lift pits and lift shafts. Just like we prioritise fit-for-purpose waterproofing for flat roofs, balconies, and basements, the lift pit demands equal attention. The lift pit, which is like a mini-basement located below ground and often near the natural water table, is an area that requires special attention to prevent water ingress.



The Risk of Lift Pit Water Leakage: Beyond Concrete Quality


In the construction phase, we often emphasize the importance of concrete quality to ensure structural integrity. However, when it comes to lift pits, concrete quality is not the sole parameter to focus on.

Adequate and effective waterproofing strategies for wall-to-floor joints, construction joints and cold joints are equally crucial. These joints can be vulnerable points for water intrusion, leading to potential water leakage in basements and lift pits.


Common reasons why lift pits are vulnerable to water ingress


  • Incorrectly installed or damaged waterproofing system.
  • The waterproofing system material naturally ages and over time
  • The pit is too old for any effective waterproofing system to have been originally installed.
  • Floor/wall joint acts as a passageway for water ingress.
  • Defects such as unintentional cold joints, honeycombed areas, and cracks in walls and floors that have evolved over the years, sometimes caused by movement.
  • Deteriorated construction components.
  • Altered water table levels.



Protection Against Deterioration

– The Importance of Proper Lift Pit Waterproofing


Lift pits and lift shafts are vulnerable to water seepage, and water infiltration can, over time, lead to corrosion and deterioration of the building elements, including the lift’s mechanical and electrical components. Periodic inspections are vital to ensure the longevity and safety of the structure.


  1. Protecting Structural Integrity


By investing in proper waterproofing, we can prevent water damage and ensure the longevity of the building’s infrastructure.


  1. Preserving Elevator Equipment


Lift machinery and electrical components are sensitive to exposure to moisture. Uncontrolled water ingress into the lift pit can lead to rust, corrosion, and even electrical malfunctions, compromising the safety and reliability of the lift.


The damage to the lift mechanism and the electrical system can result in costly repairs.


Additionally, the water in the lift pit may be contaminated by oil and grease from the lift equipment, so a sump pump is not recommended unless the disposal of any water from the pit is performed in line with environmental regulations.


Even if a lift pit is fitted with a sump pump, during heavy rain, the water may not be able to disperse due to storm drains and sewers being under extreme strain, causing pits to back up.


  1. Preventing Health and Safety Risks


Furthermore, a build-up of condensation and stagnant water in the lift pit may produce a foul smell described as ‘rotten egg’ odour, which is caused by hydrogen-sulphide gas resulting from anaerobic decomposition. This does not only smell bad, but it can be hazardous to lift technicians and maintenance contractors. Any repair works would require trained and qualified confined space entry personnel using gas exposure monitors that can detect the presence of the substance.


  1. Cost-Effective Solutions


Proactive maintenance ad remedial waterproofing, leak sealing and concrete repairs can save substantial expenses in the long run.



What can we do to remediate leaking lift pits?



  1. Regular Inspection


Schedule regular inspections to identify any signs of water damage or moisture intrusion in the lift pit. Early detection can help us tackle issues before they become a problem.


  1. Choose Quality Waterproofing Systems

Working with remedial waterproofing, leak sealing and concrete repair specialists who understand the unique challenges of each building and site situation. Utilising high-quality materials and techniques ensure a reliable and long-lasting solution.


  1. Prioritise Preventative Maintenance


Implement a comprehensive preventative maintenance plan that also includes the lift pit to address any potential water seepage to mitigate risks before they develop into an emergency leak during periods of wet weather.
