Planter Box & Basement Waterproofing Specialists in Sydney
Planter boxes and basements are two of the most common sources of ongoing water issues in residential and commercial properties. Poor drainage, membrane failure, or incorrect installation can allow moisture to penetrate concrete and masonry, leading to long-term damage.
At Real Seal Solutions, we provide professional planter box and basement waterproofing in Sydney, delivering reliable protection for new builds, renovations, and remedial projects.

Planter Box Waterproofing Sydney
Planter boxes are constantly exposed to moisture, soil pressure, and drainage challenges. Without correct waterproofing, water can migrate into walls, balconies, and internal spaces.
We waterproof planter boxes using compliant systems that include:
• Surface preparation and substrate assessment
• Certified waterproof membranes
• Proper detailing at corners, joints, and penetrations
• Drainage and overflow considerations
Our solutions are designed to prevent leaks before they become structural issues.

• Waterproof membrane installation
• Negative and positive pressure solutions (where applicable)
• Crack and joint sealing
• Long-term moisture protection systems
We tailor each solution based on site conditions and water exposure risks.

Repairs vs Full Waterproofing Replacement
In some cases, targeted repairs may be possible. However, many planter box and basement issues are caused by underlying membrane failure. We assess the site thoroughly and recommend the most effective solution to stop water ingress and prevent future damage.
