Elevators are pillars of accessibility in both public and private spaces everywhere. An essential feature of these mobility devices are their pits, which are often located at the lowest levels of buildings. Like any low space, elevator pits require protection against water damage, including flooding, sewer backups, and pipe bursts. 

In this short article with Grimebusters, we’ll be covering the end-to-end process of elevator pit waterproofing and remediation. Proudly family-owned and serving Edmonton since 1994, we’re your local trusted experts in water damage remediation. Join us as we soak up the details below!

Why Elevator Pits Need Waterproofing

Elevator pits are among the deepest parts of most buildings, making them highly susceptible to flooding. Depending on the type of elevator itself, these pits can contain highly water-sensitive components. From cables and buffers to counterweights, these elevator components are essential to safe operation and do not mix with water. Whether it’s a small puddle or a significant leak, any water can cause component failure or even corrosion if left unchecked. 

For example, hydraulic elevator pits contain pumps and hydraulic fluid. But when water from drains, sewage, or cracks gets into the pit, this hydraulic fluid combines with it. This oily, contaminated water cannot be safely removed without professional equipment and gear. 

What Are the Categories of Water Damage?

The driving reason for many elevator pit remediation calls is flooding or water damage. In fact, we can break down all water damage into three distinct categories. Here’s a quick-view list of these categories:

Category 1: Clean Water

Category 2: Grey Water

Category 3: Black Water

Depending on the source, elevator damage remediation often falls under one of the last two categories. It’s not uncommon to deal with flooded water coming from seeping groundwater (known as category 2). But overall, most cases involve highly contaminated water (category 3) that leaks in from broken sewage pipes or stormwater.

The Elevator Waterproofing Process

Before any work can be done, the elevator must be properly secured and locked out, which the elevator company can assist with. Elevator pits contain sensitive components. For that reason, we follow a comprehensive three-step process. Let’s take a closer look:

Step 1: Clean-up

• The first step in the elevator pit waterproofing process involves safely removing the standing water using commercial-grade water pumps.
• The pit is then pressure-washed and disinfected to remove any remnants of grease or contaminants. 

Step 2: Water-Proofing

• Once the pit is clean and dry, the elevator pit waterproofing process can begin. At Grimbusters, we utilize advanced crystalline technology to seal concrete effectively. This sealant works itself deep into the cracks and forms a crystal waterproof barrier. 
• These seals strengthen the concrete, to close off cracks, leaks, joints, and other weak spots where water can get in. 

Step 3: Sump Pump Installation

• The last stage of waterproofing involves fully installing a sump pump. The sump pump is your elevator’s safety net in the event of flooding, and it works to dispose of any water from the pit quickly. 

How Long Does Elevator Pit Waterproofing Take?

The elevator pit waterproofing process is relatively straightforward, typically taking less than a week. It’s a simple process in most cases, with much of the time spent waiting for materials to cure and the elevator to fully dry.
