Built-in planters are a beautiful architectural feature — often found in balconies, rooftop decks, podium courtyards, and garden terraces — but they also pose a significant waterproofing challenge. Planters that are not properly waterproofed can become a major source of water intrusion. Moisture from wet soil and irrigation systems can seep through planter walls and floors, penetrating adjacent structures and leading to interior leaks, mold growth, and structural damage. Even small leaks can cause long-term deterioration of concrete slabs, wood framing, and finishes. Our expert planter waterproofing systems provide a critical protective barrier, preventing water migration and safeguarding both the planter and the surrounding property. Whether you are building new planters or correcting issues with an existing installation, LA Waterproofer ensures your structures stay protected and beautiful for years to come.
Unlike other waterproofing applications, planters are exposed to extreme moisture on a daily basis. Irrigation, rainfall, and the natural moisture of planted soil create a highly saturated environment that can quickly break down inadequate or poorly applied waterproofing materials. At LA Waterproofer, we use advanced waterproofing systems designed specifically for planters and constantly wet environments. Our materials are highly flexible, root-resistant, and capable of withstanding continuous exposure to moisture and pressure from plant roots and soil movement. These systems bond permanently to concrete, CMU block, and other planter substrates — forming a seamless, watertight seal that remains effective over time. With our planter waterproofing services, your planters will remain leak-free and structurally sound, even under the harshest conditions.
Every planter is different — in size, shape, material, and placement — and every building has its own waterproofing challenges. That’s why we take a tailored approach to every planter waterproofing project. Whether you’re designing new architectural features or retrofitting a leaking planter in an existing structure, we carefully assess your planter’s construction and drainage. We provide expert recommendations based on planter materials (concrete, CMU, framed boxes), exposure (roof, courtyard, balcony), drainage systems, and surrounding structures. Our skilled team applies the best waterproofing methods for your specific situation — whether that’s multi-layer sheet membranes, fluid-applied barriers, or hybrid systems — to ensure durable, long-lasting protection. The result is a planter that looks great and performs flawlessly, with no risk of hidden water damage.
