Reliable Foundation Waterproofing for Long-Term Protection
When it comes to preserving the integrity of your property’s foundation, waterproofing techniques are your first line of defence. With our comprehensive knowledge and modern tools and technologies, our team can identify vulnerabilities in your foundation and implement tailor-made solutions that address your unique needs.
Basement Waterproofing
Basement waterproofing protects your home by stopping water before it causes damage. Moisture from foundation cracks can affect your walls, floors, and belongings, leading to expensive repairs.
Sealing cracks and openings prevents leaks, reduces humidity, and helps maintain your foundation’s strength over time.
Common signs of basement water issues include:
- Basement floods and puddles.
- Visible mold.
- Musty odors.
- Bowed walls.
- Cracked walls and basement floors.
- Warped doors.
Once your basement is dry and free from water infiltration, you can transform it into a functional living area. Our services not only increase the value of your home but also provide you with more living space without the need for costly renovations or additions.
Exterior Foundation Waterproofing
By applying waterproofing membranes to the outside of your foundation walls, exterior foundation waterproofing prevents moisture from entering your basement or crawl space. A properly installed French drain system then directs water away from the home to a safe discharge point.
When you hire our Montreal waterproofing company, our experts perform the following steps to repair your basement’s water membrane:
- 1. Excavating down to the footing of your foundation
- 2. Cleaning the exposed foundation walls of all debris
- 3. Repairing any foundation cracks to stop infiltration
- 4. Installing two durable waterproofing membranes for long-term protection
- 5. Installing 4-inch PVC perforated French drains with the correct slope toward the sump pump basin
- 6. Backfilling and leveling the property for a clean, finished appearance
This comprehensive approach ensures your foundation stays dry, stable, and protected for years.
Interior Waterproofing Services
Interior waterproofing is a smart solution for stopping water intrusion when exterior excavation isn’t possible. Waterproofing basement walls from inside the building effectively manages water, seals problem areas, and prevents recurring leaks.
Interior basement waterproofing is ideal for:
- Water entering through walls, floor joints, or small cracks
- Moisture or dampness appearing after rainfall
- Puddles forming along basement edges
- High humidity or musty basement odors
Our team installs interior basement waterproofing systems using durable, long-lasting materials. This clean, efficient approach keeps your basement dry with minimal disruption, perfect for finished basements or homes needing a non-invasive solution.

FAQs
Common warning signs include water puddles, damp or chalky walls, musty odors, mold growth, cracked walls or floors, warped doors, and high humidity. If you notice moisture after rainfall or see water entering through joints or cracks, it’s time to contact LFNG.
Leaks can come from hydrostatic pressure, poor drainage, clogged or failing French drains, porous concrete, or faulty window wells. Waterproofing systems address these hidden sources by redirecting water away from the home and sealing vulnerable points inside the basement.
Small surface cracks may seem easy to patch, but DIY sealants rarely address the underlying cause of water intrusion. Improper repairs can also trap moisture or worsen the problem. Professional waterproofing ensures the source of the issue is found and repaired correctly.
The best method depends on where the water is coming from.
- Exterior waterproofing protects the foundation from the outside using membranes and French drains.
- Interior waterproofing manages water that reaches the basement by directing it into drainage channels.
A professional assessment determines which approach will provide the most effective long-term solution.
Yes! Interior waterproofing is ideal for finished basements because it requires minimal disruption. We install drainage channels and seal vulnerable areas from the inside without tearing apart the entire space.
Waterproofing cost will vary depending on the size of the area, severity of the water issue, and whether interior or exterior waterproofing is needed. We provide a free on-site inspection and transparent estimate so you understand exactly what’s required.
