How Does Interior Basement Waterproofing Work?

When you notice moisture in your basement, the most important thing to do is call the experts to get it taken care of right away. Mold can grow in even small amounts of water, and mold grows extremely quickly.

Interior waterproofing removes moisture from the basement using water control techniques. Drainage channels are installed, which lead to a sump pump, which removes the water.

How Basement Waterproofing is Done

Our Process for Fool-Proof Waterproofing

Installing a waterproof membrane on the wall

The use of a basement wall waterproofing membrane will prevent water from entering the basement and causing dampness.

To avoid future moisture problems, it is best to install a waterproof membrane on both the floor and the walls.

Digging a trench and installing a drain

Our experts dig a trench down to the foundation footings and install a bed of washed gravel.

The flexible pipe will be wrapped in a filtration fabric "sock" and connected to the sump basin before being laid in the trench all the way around the basement and connected to the basin on the other side.

Channeling water into a drain

By diverting water away from the foundation, French drains, a common and highly effective basement waterproofing system, keep basements dry.

Pumping out accumulated water

Sump pumps are a common feature in basements with groundwater intrusion issues. They can, however, remove flooding from the basement.

Is It Better to Waterproof the Basement From the Inside or Outside?

For preventing wet basements, interior basement waterproofing systems are thought to be better and more efficient. Your basement can be waterproofed using a system of interior weeping tiles.


From the outside

  • Due to its greater labor requirements, this method is the most expensive way to waterproof your home. To keep water out, drainage systems must be set up, which requires extensive digging.
  • Professionals like Royal Work Corp. will install French drains on the exterior, and this procedure may be the best defense against flooding and water damage to your home.


From the inside

  • Interior waterproofing is less expensive because it is easier to access, has a faster installation process, and requires less labor overall.
  • Interior waterproofing eliminates the need for extensive digging or removing dirt from the exterior of your home. Our professionals can install sump pumps and other devices to help remove water from crawl spaces and basements.

The Dangers of Not Waterproofing Your Basement

Health Issues Because of Mold and Mildew Growth

Mold and mildew spores are released into the air as they grow. Some people may develop allergic reactions to these spores, and they can also damage fabrics and other materials.

Inhaling mold spores can result in a wide range of respiratory issues, from allergies and asthma to more serious illnesses like bronchitis and pneumonia.

Structural Damage

Water is one of the most destructive elements in your basement and foundation. Water leaking through cracks or pores in your basement walls or foundation can cause a variety of issues.

It can erode the concrete or masonry, weakening and making the structure more prone to collapse. It can also saturate the soil around your foundation, causing it to expand and put pressure on the foundation walls.

Basement Flooding

Basement waterproofing is not an easy task. You will require the services of a company that specializes in waterproofing. They should also understand the root cause of the problem before attempting to solve it.

A company that has been in operation for at least ten years is more likely to be suitable for your position.

Wall Cracks

When a footing drain becomes clogged, water that is intended to enter the drain gathers around the foundation and begins to push against the basement walls of the home. This pressure causes the bowing or tilting of basement walls, resulting in cracks and water leakage.

Let's Talk
How much does it cost to waterproof a basement in Toronto?
Prior to basement waterproofing and foundation repair, our experienced sales representatives will provide a written estimate. Before beginning any waterproofing project, our customers should speak with one of our sales representatives and obtain a written estimate.
How do I stop water from seeping through concrete walls?
Polyurethane foams can be used to seal concrete leaks. The crack must be large enough to accommodate foam filling. Polyurethane foam reacts with water, hardening and filling the crack. These foams provide waterproof protection against future leaks.
How do you waterproof a foundation wall?
A liquid-applied membrane is typically used as the primary waterproofing layer for a foundation wall. Two layers of an external waterproofing product are recommended.

We only use the highest quality materials and products on the market at Royal Work. They can be applied up to three meters underground with a brush, a brush/trowel, or an airless spray.
How long does waterproofing a basement take?
To summarize, Basement Waterproofing timelines can vary depending on the work required. As a general rule, projects should be completed within three days, and in many cases much sooner.

The majority of our repairs are completed within a day. When we have larger projects, the timeline can be extended by 2-3 days.
