Water intrusion can be a frustrating and potentially damaging issue for garage conversions. Ensuring your converted garage stays dry and comfortable requires identifying the source of the problem and implementing effective waterproofing solutions. Here’s a guide to help you tackle this issue.
1. Identify the Source of Water Intrusion
To address the problem, you first need to pinpoint where the water is coming from. Common sources include:
- Improper Drainage: Rainwater pooling near the foundation due to poor grading or inadequate drainage systems.
- Cracks or Gaps: Gaps in the floor or at the junction of the walls and concrete slab can allow water to seep in.
- Damp or Porous Walls: Walls not adequately treated for damp resistance can let water penetrate.
- Surface Water Runoff: Heavy rain that flows directly toward the garage can breach weak points in the structure.
2. Solutions to Prevent Water Intrusion
Once you’ve identified the source, these steps can help you waterproof your garage conversion effectively:
Damp-Proof Membrane (DPM)
- Install a damp-proof membrane beneath the concrete floor. This creates a barrier to prevent moisture from rising through the slab.
- Ensure the membrane is properly sealed at the edges and overlaps to cover the entire area.

Sealing Cracks and Gaps
- Use high-quality silicone sealant or a waterproofing compound to seal any visible cracks or gaps in the walls and floor.
- Ensure the joint where the wall meets the floor is well-sealed.
Install Proper Drainage
- Add a French drain or channel drainage around the exterior of the garage to direct rainwater away from the foundation.
- Clean and maintain gutters and downspouts to ensure efficient water flow, redirecting runoff away from the building.
Floor Levelling
- Consider raising or levelling the garage floor to prevent water from pooling and seeping through.
Waterproof Coatings
- Apply a waterproof coating to the interior walls and floor for an additional layer of protection.
- For external walls, use a breathable water-resistant treatment to prevent rain penetration.
Threshold and Edging Improvements
- Install a raised threshold at the garage entrance to act as a barrier against surface water.
- Use weatherproof strips to seal any gaps under doors.
3. Long-Term Prevention Tips
- Ensure Proper Grading: The ground around your garage should slope away from the structure to prevent water from pooling.
- Regular Maintenance: Check for cracks, gaps, or blocked drainage systems periodically and address any issues promptly.
- Ventilation: Proper ventilation helps manage indoor moisture levels, preventing condensation buildup.
4. When to Call a Professional
For severe water intrusion issues, it’s best to consult experts. Professional builders can:
- Conduct a thorough inspection to identify and address underlying problems.
- Recommend tailored solutions, such as advanced drainage systems or structural repairs.
- Ensure compliance with building regulations for damp-proofing and waterproofing.
