The Basics of Interior Waterproofing

The Basics of Interior Waterproofing

What is interior waterproofing?

The process of waterproofing a foundation from the inside of a house or structure is known as interior waterproofing. Interior waterproofing is an excellent means of keeping your basement dry. It is a cost efficient way to waterproof your basement compared to other techniques like exterior waterproofing.

Do I need to waterproof my Kitchener home?

Waterproofing your foundation is critical to keeping your basement dry and mold-free. If the water around your Kitchener house has nowhere to go, it will leak through your basement walls and floors. Exterior groundwater puts hydrostatic pressure against your foundation walls and basement floor, causing the water to pool and seep through your foundation cracks if there is no escape path.

Waterproofing your basement will allow you to live in a dry, mold-free environment. It creates livable and usable space, and external waterproofing can even keep your home’s foundation strong.

How does interior waterproofing work?

A weeping tile system is another term for interior waterproofing. Interior waterproofing does not officially waterproof a basement, but it successfully controls seeping water and directs it away from the foundation. Interior waterproofing can also be referred to as a water management system.

Water can safely leak through the holes in your foundation walls thanks to the inside waterproofing system. Water enters your property and flows down your waterproofing membrane and into your weeping tiles. The entering water will be collected and directed to a sump pump by your weeping tile system. The sump pump will then direct the water to a safe location outside your property (the water will then be removed through storm drain, dry well, drainage ditch, or a low-lying area).

What is the interior waterproofing installation process?

1. Obtain access to the bare foundation wall.

2. Cut a weeping tile channel in the floor slabs (The channel is dug approximately 18 inches from the footings of your home).

3. Put in place and fasten the weeping tile system.

4. Apply the waterproofing membrane to the internal walls and footings of the foundation.

5. Re-lay concrete above your weeping tile channel and backfill with gravel.

6. Clear the worksite.

How long does it take to install a waterproofing system in the home? (Weeping Tile System)

Interior waterproofing can take anything from one to ten days on average. The following factors may influence job length: foundation wall condition, foundation wall material (concrete block, poured concrete, etc.), site access, foundation wall length, foundation wall height, floor and wall excavation requirements, sump pump systems, and more.

What is the cost of interior waterproofing?

As waterproofing professionals who have done over 50 million square feet of waterproofing treatments throughout Central, Ontario, we can tell you that pricing a waterproofing job without viewing the job site is extremely difficult. Although pictures can assist calculate an exact pricing, there are other elements that might affect the cost of a waterproofing job.

The condition of the foundation wall, the foundation wall material (concrete block, poured concrete, etc), basement floor materials, site access, foundation wall length, foundation wall height, excavation demands, sump pump systems, and other factors all affect the cost of interior waterproofing.

Interior waterproofing costs between $65 and $100 per linear foot. The above-mentioned site conditions have an impact on this price.

Are sump pumps worth it?

They certainly are! Sump pumps are the basement’s last line of defence. Sump pumps can be set to activate automatically when the water level in the basin or pit reaches a certain level (this is the most economical way to maintain a sump pump). We also recommend adding a backup battery to keep your sump pump running in the event of a power loss.
