Keep Your Garage Floors Dry: Best Practices for a Cleaner, Safer Space

Ever walked into your garage only to find a damp floor? It’s frustrating, slippery, and can even lead to mould problems if left unchecked. The good news? A few simple design and construction techniques can help you avoid water pooling and create a garage that’s both functional and resilient.

What Causes Wet Garage Floors?

A wet garage floor is often the result of poor drainage, condensation, or unsuitable building materials. Factors such as roof runoff, inadequate falls in the slab, or improper material choices can contribute to moisture issues.

Smart Solutions for Dry Garage Floors

✅ Slope Your Garage Floor Correctly
A proper slope is key to preventing water from pooling inside your garage. The National Construction Code (NCC) specifies a minimum of 1.2m clearance in front of the pan and at least a 1:100 fall to ensure water drains effectively. If your client wants the ability to hose out the garage, make sure the slope is done properly—and don’t forget to charge accordingly!

Choose the Right Materials

• Avoid colour-coated metal near the sea, pools, or roof-mounted pool heating to reduce rust.
• Invest in high-quality, durable materials that are water-resistant.
• Use anti-mould additives and ensure proper ventilation to prevent condensation build-up.

Consider Essential Features

• • Install grab rails at 800–810mm for better accessibility and safety.
  • A vertical grab rail can provide extra stability, especially for older adults.
  • Prevent water damage by sealing every joint carefully with paintable sealants.
  • Prime the ends of doors, exterior wood, and any timber exposed to damp environments.

Final Thoughts

A well-designed garage is more than just a storage space—it’s an extension of your home. By paying attention to drainage, materials, and essential safety features, you can prevent water damage, improve longevity, and create a more functional space.
