DIY Basement Waterproofing: Waterproof Your Basement Like A Pro

Managing a damp basement is very annoying. Hiring a waterproofing expert is often expensive. Luckily, homeowners often find it possible to waterproof basements themselves. This guide goes through DIY basement waterproofing methods to keep water away from your home using easy steps, simple tools and useful waterproof materials.

1. Signs You Need to Waterproof Your Basement

Before leaping into waterproofing, it’s best to look out for these signs in your basement:

• Damp spots on the basement walls or floor
• Visible mould growth
• Peeling paint or water stains
• A musty odour lingering in the space
• Small puddles or signs of water seepage

If you spot any of these, it’s time to take action to prevent further water damage and protect your basement.

2. Preparing Your Basement for Waterproofing

Preparation is key to DIY basement waterproofing. Here’s how to get your space ready:

• Clear the Area: Shift furniture and stored things to reach walls and floors completely.
• Clean Surfaces: Mix bleach with water and scrub surfaces with a wire brush to take away mould and dirt. This ensures a clean surface for the waterproof coating.
• Look for Cracks: Search foundation walls for any cracks. Apply hydraulic cement to fill them because it spreads and hardens to provide a solid shield.
• Protective Gear: Wear gloves and a mask when working with chemicals or dealing with mould.

3. Steps for Waterproofing a Basement

To waterproof a basement, follow these DIY steps:

a. Seal Cracks and Joints

• Apply Hydraulic Cement: After identifying cracks, use hydraulic cement to fill them. Mix the cement according to the manufacturer’s instructions and press it into the cracks using a putty knife. This prevents water from entering.
• Inspect Sealed Areas: Ensure the cement has cured fully before moving to the next step.

b. Apply a Waterproof Coating

• Choose Waterproof Paint or Coating: A waterproof coating is needed to prevent water from leaking into your basement. Search for a product made especially for basement tanking.
• Apply Two Coats: For excellent outcomes, apply at least two coats of waterproof paint. Use a roller for smooth application and a brush for small corners.
• Drying Time: Let each layer dry fully before putting on the next.

4. Interior vs. Exterior Waterproofing

Understanding the difference between interior waterproofing and exterior waterproofing helps you choose what’s right for your DIY project:

• Interior Waterproofing: Involves using special coatings inside the basement to stop moisture. This method helps with stopping small leaks and is often a faster fix.
• Exterior Waterproofing: This involves digging around the foundation and applying a waterproofing membrane. It’s more labour-intensive and may be best left to the professionals, but it offers full protection to stop damp on external walls.

5. Creating a Drainage System

Waterproofing means more than using a sealant. If your basement stays wet, a drainage system might help:

• Install a Sump Pump: This tool helps control excess water and moves it away from the house.
• Improve Gutters and Downspouts: Keep gutters clean so water flows away from the foundation. Blocked gutters lead to water collecting near your home.
• French Drains: If you do not mind digging, a French drain moves water away from the basement and lowers pressure on the walls.

6. Tips for Maintaining a Dry Basement

Even after waterproofing, regular maintenance keeps water away and protects your basement:

• Regularly Check for Leaks: Inspect your basement walls and floors periodically for new cracks or signs of moisture.
• Keep the Outside Dry: Ensure that the ground slopes away from your home so water naturally flows away from the foundation.
• Maintain Your Sump Pump: Test your sump pump periodically and consider having a backup power source in case of a power outage.
• Seal Windows and Openings: Use waterproof sealant to close gaps around windows and other openings to keep water out.

7. Waterproofing Products to Consider

Choosing the right waterproofing products is crucial for success. Here are some essentials:

• Waterproof Paint: Ideal for walls and floors to stop water from seeping in.
• Hydraulic Cement: Best for filling cracks and stopping water leaks.
• Waterproofing Membrane: For those tackling exterior waterproofing.
• Crack Sealers: Flexible and easy to apply for minor gaps.
• Drainage Systems: Components like sump pumps and French drains to keep water moving away from your basement.

8. When to Call in a Professional

Sometimes, DIY waterproofing might not be enough, especially if you’re dealing with significant structural damage or deep foundation cracks. Here’s when you should consider calling in a professional:

• Persistent Water Problems: If you notice continuous water seeping even after your waterproofing efforts.
• Structural Integrity Concerns: Cracks larger than 1/4 inch or signs of foundation shifting.
• High Water Table: Homes built in areas with a high water table may require professional intervention for a long-term solution.

9. Cost to Waterproof a Basement

The cost to waterproof a basement can vary greatly based on the method:

• DIY Costs: Basic materials like sealant, paint, and hydraulic cement can range from £100 to £500.
• Professional Services: Hiring a waterproofing contractor can start at £1,000 and go up, depending on the scope and type of waterproofing system needed.

10. Why Some Basement Waterproofing Jobs Are Best Left to Professionals Like APP

DIY basement waterproofing can work for minor issues. However, sometimes getting professional help is the better choice. Companies like APP specialise in tackling complex waterproofing problems and delivering high-quality, long-lasting solutions. Here’s why you might want to leave some waterproofing projects to professionals:

a. Complex Structural Repairs

If your basement has big structural problems, such as large foundation cracks or moving walls, having an expert is really important. These problems often need more than just putting on a waterproof coating. Experts like APP offer full inspections and structural reinforcement that keep your basement’s structure safe.

b. Advanced Waterproofing Systems

Professionals can install more sophisticated waterproofing systems that go beyond simple interior coatings:

• Exterior Waterproofing: This involves excavating around the foundation and applying a waterproofing membrane. It’s an extensive job that requires the right equipment and experience.
• Custom Drainage Solutions: APP and similar companies can install specialised drainage systems, like exterior and interior French drains or sump pumps, tailored to your home’s specific needs.
• Waterproofing Membranes and Sealants: Professionals have access to industrial-grade waterproofing products that can handle severe water pressure and prevent long-term damage.

c. Persistent Water Problems and Hydrostatic Pressure

If you’re dealing with persistent water problems or high hydrostatic pressure, professional intervention is often necessary. Hydrostatic pressure can push water through walls and floors, even with basic interior waterproofing. Companies like APP are experienced in identifying the source of water problems and applying solutions that keep water away from your foundation effectively.

d. Peace of Mind and Cost-Effective Solutions

While the average cost to waterproof a basement with professionals may seem higher upfront, it can save you from costly repairs and repeated DIY attempts that don’t fully solve the issue. Experts like APP can offer warranties and assurances, giving homeowners peace of mind knowing that their basement waterproofing solution will last.

e. Professional Experience and Tools

With 50 years of experience and access to advanced tools, a professional waterproofing contractor like APP can find hidden problems that homeowners might overlook. This thorough work makes sure the task is completed correctly the first time, so your basement stays dry and safe for many years.
