When to Combine Foundation Piers with Basement Waterproofing

Published: January 17, 2026

When homeowners face foundation and water problems at the same time, it can be difficult to decide which issue to tackle first. In many cases, the best solution isn’t choosing one or the other — it’s combining foundation piers with basement waterproofing. Together, these systems provide both structural stability and long-term moisture protection for your home.

What Are Foundation Piers?

Foundation piers are structural supports installed beneath a home to stabilize or lift a foundation that has shifted. They’re commonly used when:

• The soil beneath the home is unstable
• The foundation is settling unevenly
• There are cracks in walls, floors, or ceilings
• Doors and windows no longer open and close properly

By transferring the home’s weight from unstable soil to deeper, more stable ground, foundation piers restore stability and help prevent further movement.

Why Basement Waterproofing Matters

Even a strong foundation is at risk if water is constantly pressing against it. Basement waterproofing protects against:

• Water seepage through cracks and porous concrete
• Hydrostatic pressure that pushes water through walls and floors
• Mould and mildew growth caused by persistent dampness
• Property damage to flooring, drywall, and stored belongings

Waterproofing methods can include interior drainage systems, sump pumps, wall sealants, and exterior solutions to keep your basement dry.

When to Combine Piers and Waterproofing

In some situations, using both systems together provides the most effective and long-lasting results.

1. Foundation Cracks Allowing Water In

If your foundation has cracked due to settling, those same cracks can act as entry points for water. Installing piers stops the movement, while waterproofing ensures water doesn’t get inside.

2. Homes in High Water Table Areas

If your property experiences chronic water pressure around the foundation, waterproofing alone may not be enough. Piers prevent structural shifting while drainage systems manage water.

3. Severe Settlement with Basement Leaks

A sinking foundation can pull walls apart, creating gaps that let water through. Combining piers with waterproofing addresses both the cause (soil instability) and the effect (water intrusion).

4. Long-Term Protection During Major Repairs

If you’re investing in foundation stabilization, it’s wise to protect that investment by also waterproofing. Together, they extend the lifespan of both the structure and the repair work.

Benefits of Combining Both Systems

• Comprehensive protection — you solve structural and water issues at the same time
• Cost savings over time — prevents repeating repairs by addressing underlying causes
• Improved property value — a stable, dry basement is a strong selling point
• Peace of mind — you won’t have to worry about ongoing cracks or water seepage

When to Call a Professional

If you notice foundation movement and water leaks in your basement, it’s best not to delay. Signs include:

• Horizontal or widening foundation cracks
• Bowing basement walls
• Persistent dampness or flooding
• Musty odours and mould growth
• Uneven floors or sticking doors and windows
