Concrete Planter

What are good concrete planters?

When searching for high-quality concrete planters, the material composition is decisive for the lifespan. Nowadays, good concrete planters are manufactured from polymer concrete (StoneCore), a high-quality mixture of natural minerals and resins. This material is up to five times stronger than traditional concrete and completely liquid-tight, preventing cracks from forming due to freezing. An essential quality feature of a good concrete planter is the finish; it should be seamless and have very high compressive strength. When choosing a concrete planter, also pay attention to UV resistance so that the characteristic grey tones are retained even after years in full sun.

Why choose a concrete planter?

Choosing a concrete planter from the StoneCore series means choosing an extremely durable and maintenance-free product. Unlike classic concrete, these concrete planters are much lighter in weight, which significantly simplifies installation on terraces and balconies. The material is pore-free, meaning algae and moss can hardly adhere to the walls of the concrete planter. Additionally, polymer concrete has a natural, matte appearance that perfectly complements modern architecture and sleek garden designs. Moreover, a concrete planter is 100% recyclable and resistant to the most extreme weather conditions, from deep frost to scorching heat.

How to install concrete planters?

Installing concrete planters requires a stable base to ensure clean lines. Follow these steps for proper installation:

• Ensure a completely flat and load-bearing surface to prevent point loading on the bottom of the concrete planter.
• Although StoneCore planters are lighter than solid concrete, they are still solid; Therefore, always lift the concrete planter into the correct position with sufficient people or tools. For outdoor use, check that the drainage holes are clear so that excess water can exit the planter immediately through the bottom of the concrete planters. Place the planter directly at its final location before you start filling it, as a filled planter is virtually immovable.

  How do you fill a concrete planter?

  A proper layering structure in a concrete planter is essential for healthy plant growth. Start with a layer of hydro granules of approximately 10 to 15 centimeters. This ensures weight savings and optimal water management at the bottom of the concrete planter. Place a water-permeable root barrier fabric over this to prevent the potting soil from disrupting drainage. Then fill the concrete planters with high-quality potting soil tailored to your plants. Leave a watering rim of approximately 5 centimeters free at the top. This prevents muddy water from running over the sleek edges of the concrete planter, keeping the exterior clean for longer.

  Maintaining a concrete planter

  Maintenance of StoneCore concrete planters is minimal thanks to the material's pore-free structure. We recommend cleaning the planters one to two times a year with a soft brush and lukewarm water. Never use a high-pressure cleaner or aggressive chemical cleaning agents on a concrete planter, as this can damage the natural mineral finish. For stubborn dirt on the concrete planter, a mild soap solution will suffice. By wiping down the planter periodically, the polymer concrete retains its characteristic, stone-like sheen and preserves its modern appearance for years to come.

  Frequently asked questions about concrete planters

  Is a StoneCore concrete planter completely frost-resistant?

  Yes, the StoneCore concrete planter is extremely frost-resistant. Because polymer concrete does not absorb water (0% water absorption), the wall of the concrete planter cannot crack or crumble due to freezing, which is often the case with traditional concrete.

  How heavy are these concrete planters?

  Although a StoneCore concrete planter looks very robust, it weighs significantly less than a comparable planter made of traditional concrete. This makes the concrete planters easier to transport and position, without compromising stability or strength.

  Can these concrete planters discolour?

  The concrete planter is coloured throughout with natural minerals. As a result, the concrete planter is very colourfast and UV-resistant. Even after years of standing outside in all weathers, the concrete planters retain their authentic grey concrete look.

  Are concrete planters suitable for trees?

  Absolutely. Thanks to the enormous compressive strength and stability, a large concrete planter is extremely suitable for planting shrubs and small trees. The walls of the concrete planter are strong enough to effortlessly withstand root pressure over a long period.
