Common Waterproofing Problems and How to Solve Them

Common Waterproofing Problems and How to Solve Them

Water is the ultimate source of life in our environment. It can carve canyons and shape landscapes, but when it penetrates into our structures, it can lead to devastating consequences. Waterproofing is the process of making a structure or object resistant to water. It is an important part of construction and maintenance, as water damage can be costly and disruptive.

There are a variety of waterproofing solutions available, and the best solution for a particular application will depend on factors such as the type of structure, the climate, and the budget. In this article, we will explore common waterproofing problems and their solutions, while emphasizing the role of expert waterproofing contractors and services.

The Role of Waterproofing Services

Waterproofing is not a one-time solution for water related problems, it requires expert knowledge, guidance, and skills. This is where professional waterproofing contractors come into the picture, to ensure that your building and structures remain immune to water infiltration. Let’s dive deep into some of the common waterproofing problems and how expert professionals offer innovative solutions.

1. Roof Leaks

Problem: Roofs are one of the most common sources of water leaks. This is because they are exposed to the elements, including rain, snow, and ice. Leaks can occur at seams, around flashing, or through cracks in the roof material.

Solution: Expert waterproofing contractors will inspect your roof and identify weak points. They’ll recommend roof repairs or replacement, ensuring that your structure remains secure. Professional contractors understand the complexity of roofing materials and are experts in performing effective waterproofing work.

2. Basement Water Leakage

Problem: Water leakage into basements through foundation cracks, poor drainage, or improper waterproofing systems can lead to leakage problems.

Solution: Waterproofing contractors will assess the foundation’s condition, sealing any cracks with precision. They may recommend French drains and exterior waterproofing membranes to redirect and block water insertion. Their expertise is essential for protecting your basement against water damage.

3. Leaking Windows and Doors

Problem: Improperly sealed windows and doors can allow water to enter, leading to interior damage and mold growth.

Solution: Experts will re-caulk or weatherstrip around windows and doors to ensure an airtight seal. They will also verify proper flashing installation, redirecting water away from openings. This attention to detail is crucial for long-term waterproofing.

4. Sump Pump Failure

Problem: A sump pump is a device used in buildings, particularly in basements and crawl spaces, to remove excess water that accumulates due to various sources, such as rainwater, groundwater, or natural seepage. Sump pumps can fail sometimes, leaving your basement vulnerable to flooding during heavy rainfall or snowmelt.

Solution: Professional waterproofing contractors can install backup sump pump systems, such as battery backups or water-powered backups, to ensure that water is efficiently pumped out, even when the primary pump fails.

5. Cracked Foundation

Problem: Foundation cracks allow water to seep into the basement or crawl space, causing structural damage.

Solution: Waterproofing contractors are skilled in repairing foundation cracks using specialized materials like Epoxy or Polyurethane Injection. They can also strengthen foundations when necessary, protecting your building’s structural safety.

6. Damp Crawl Spaces

Problem: A damp crawl space is a space beneath a building that is often filled with moisture. Crawl spaces can become damp due to leaks, poor ventilation, or high humidity. Damp crawl spaces can create a number of problems, including mold growth, wood rot, and structural damage.

Solution: The professionals will install vapour barriers on the ground and walls of the crawl space to prevent moisture entry. They will ensure proper ventilation and drainage, thus transforming these spaces into dry, healthy environments.

7. Exterior Wall Leaks

Problem: Water can penetrate exterior walls through cracks, poorly sealed joints, or deteriorated siding. This can cause damage to the walls of the building, including mold growth and peeling paint.

Solution: Experts will conduct thorough inspections and repair wall cracks, reseal joints, and replace damaged siding. Applying a waterproofing membrane or coating to the exterior is another strategy they employ to keep your walls impervious to moisture.

8. Balcony and Deck Leaks

Problem: Balconies and decks can develop leaks due to poor construction or aging materials.

Solution: Waterproofing contractors, with their expertise in materials and construction, perform regular inspections and maintenance. They will repair or replace damaged materials and ensure the proper slope for water runoff, preserving the safety and durability of these outdoor spaces.

9. Inadequate Gutter and Downspout Systems

Problem: Improperly sized or clogged gutters and downspouts can lead to water overflow and damage to the building’s foundation.

Solution: Expert contractors will recommend the correct gutter size for your roof and ensure regular cleaning and maintenance. They will also guide you in directing downspouts away from the foundation, protecting it from potential water damage.

10. Poor Grading and Drainage

Problem: Incorrect grading and drainage can lead to water pooling near the building, increasing the risk of water infiltration.
Solution: Waterproofing contractors can adjust the slope of the ground to facilitate water runoff away from the building. They can also install proper drainage systems to efficiently manage excess water.

Waterproofing Techniques

There are a variety of waterproofing techniques available, including:

  • Membranes: Waterproofing membranes are thin layers of material that are applied to surfaces to prevent water penetration. Membranes can be made from a variety of materials, including bitumen, asphalt, and PVC.
  • Coatings: Waterproofing coatings are applied to surfaces to create a barrier that prevents water from penetrating. Coatings can be made from a variety of materials, including acrylic, polyurethane, and epoxy.
  • Injections: Waterproofing injections are used to fill cracks and voids in concrete and masonry structures. Injections can be made from a variety of materials, including epoxy, polyurethane, and acrylic.
