LIFT PITS ARE LIKE MINI BASEMENTS AND THEY OFTEN LEAK

Do you associate water leaks with lift problems?

As part of building maintenance, it is important to ensure that certain facilities are well maintained to ensure safety. Lifts need to be inspected periodically to ensure a safe building environment. In order to ensure that lifts are safe and working properly, they require appropriate service maintenance and repairs.

Lift pits are like mini basements because they are almost always below ground. Rising water table levels usually occur during the wet season, making them vulnerable. Interesting, the water table level can be altered by nearby construction, so a lift pit that used to be dry can now be threatened by water infiltration. Water can enter the lift pit through joints in construction, cracks in the walls, or leaks in the floor. The path of least resistance can be followed by water to find its way through any weak points. If water enters the lift pit, it will pool on the floor and keep rising until it reaches the water table’s height.

Could water seeping into the lift pit result in a broken-down lift?

The lift pit and lift shaft hold all the technology and electric mechanisms connected to the lift itself, so if water is leaking into the lift pit or the lift shaft there is a real potential of costly damage to the lift and the situation can become dangerous – In addition to potentially expensive repairs, electrical or mechanical failures can cause abrupt stops where passengers may risk sustaining injuries.

HOW CAN SINGAPORE WATERPROOFING HELP KEEP YOUR LIFT PIT DRY AND PREVENT MOISTURE FROM MAKING ITS WAY IN?

We at Singapore Waterproofing can remediate your leaking lift pit and lift shaft to a dry and safe condition and help protect your asset from breakdown caused by water ingress.

In hotels, commercial buildings, factories, multi-level apartment buildings, schools, aged care facilities, hospitals, we leak seal and install waterproofing systems to lift pits that are of any age.

It is difficult to successfully seal water that enters through access points, and patching them up rarely works. Using targeted high-pressure injection of hydrophilic polyurethane into leaking wall-floor joints and/or vertical joints, leaky lift pits and lift shafts can be cost-effectively remediated.

Specifically, we inject high-pressure polyurethane resin at intervals of approximately 200mm into the leaking floor/wall joint or vertical joint. By injecting the hydrophilic polyurethane resin into cracks, water is chased deep into the concrete, forming a durable, flexible, and watertight seal that bonds strongly.

Through a combination of proprietary methods developed and refined over thousands of projects, our technicians manage the injection process to create a continuous three-dimensional seal buried within the concrete.

After the polyurethane reacts and binds with any water present in the crack and surrounding concrete to form a flexible seal, injection ports are removed and holes filled with a suitable rapid set concrete repair material.

This remedial waterproofing treatment was (in this lift pit) followed by installing a polymer modified cementitious waterproofing membrane in multiple layers over a water-borne epoxy primer.
