What problems can a leaking lift pit cause?


Consequences of water ingress to the lift pit

Water in the lift pit can lead to Health & Safety issues and costly lift break down.

Any water in the lift pit can affect the lift mechanism and electrical systems, which may lead to the lift breaking down. If the water touches the lift’s electrical items, the situation can become very dangerous. Corrosion of essential lift parts is potentially a risk to safety. The damage to the lift mechanism and the electrical system can result in costly repairs.

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.

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-sulfide 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.

 

Why does lift pit waterproofing fail so often?

A common problem with lift shafts is groundwater ingress into the lift pit area. We often discover that the source of water ingress into lift pits are due to:

  • Incorrectly installed or damaged waterproofing system.
  • 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 and cracks in walls and floor that have evolved over the years, sometimes caused by movement.
  • Deteriorated construction components.
  • Altered water table levels.

 

Lift pits are like mini basements because they are almost always below ground. The design of a lift pit should be considered as an integral part of the structure/building design and waterproofed to prevent water ingress.

Lift pits are vulnerable to rising water table levels, especially during the wet season. The water table can be altered by adjacent construction, so a lift pit that used to be dry can now be at risk of water intruding the structure. Water can enter the lift pit via construction joints, cracks in the walls or floor. Water has a way of finding a way through any weak points following the path of least resistance. Once water has entered the lift pit, it will pool on the floor and keep rising, usually until it has reached the height of the water table.

 

How can Waterstop Solutions help keep your basement and lift pit dry and prevent moisture from making its way in?

Wall to floor joints in infill slabs and retaining walls and service pipe penetrations often act at basement leakage points. This can cost-effectively be remediated. Water that enters through access points can be tricky to successfully seal and patching things up rarely works. A wet basement/lift pit can be treated by targeted high-pressure injection into the wall-floor joint and/or into vertical joints, such as between contiguous piles. The injected hydrophilic polyurethane liquid chases the water deep into cracks and forms a flexible watertight seal. This remedial waterproofing treatment can be followed by the application of an epoxy coating or a negative side membrane.
