Cast Stone Material Spec Sheet PDF
GFRC Material Spec Sheet PDF
All of our cast stone pieces are manufactured with a high density cast stone mix with a PSI (pounds per square inch) strength of approximately 7,500.While this high density mixture is designed to produce a strong and durable product, proper maintenance is recommended to protect our product from the freeze-thaw cycles that occur in winter. Any piece which can hold water, snow or ice, such as a planter, birdbath/ fountain top or shell, and any piece which is placed directly on the ground surface, such as a statue, birdbath/fountain base, planter or bench leg, can be damaged by the winter freeze-thaw cycles.
Cast Stone & GFRC Planters – If a planter is to be left planted over the winter, it should be raised up off the ground by placing two (2) pressure treated wood strips underneath the planter, making sure not to block the drainage hole. Attractive pot risers sold by Campania may also be used for this purpose. This will allow the soil to drain and will prevent the planter from freezing to the ground. If a planter is placed directly on the ground and goes through several freeze-thaw cycles, drainage may be blocked. This may cause an expansion of the soil inside the planter, which in turn may cause the planter to crack or crumble. We always recommend that drainage materials such as small stones or terra cotta chips be placed at the bottom of the planter before filling with soil to ensure proper drainage. If a planter is not to remain planted over the winter, we suggest that it be stored in a covered area where it will be protected from the elements. If a planter must be left outside unplanted, we suggest that it be emptied and turned upside down onto wood strips. It should then be covered or wrapped with burlap or any absorbent material (old blanket/towel) and then wrapped with dark plastic. This will prevent moisture from accumulating in the planter. Please note that even if a cast stone container is raised off the ground, there is always the risk that the container will absorb water through its surface which, when frozen, can cause the planter to crack or break.
Glazed/Terra Cotta Material Spec Sheet PDF
Our glazed and terra cotta pottery is high fired between 990 (terra cotta) and 1000 (glazed) degrees centigrade to ensure frost resistance and durability. They are also subjected to rigorous testing in freeze-thaw conditions to ensure quality. Due to the processes used in the manufacturing of our hand-made and hand-glazed containers, all variations with respect to firing, color, size and crackling are not deemed to be defects but are natural occurrences in the manufacturing process. The glazes on our containers consist of natural, not chemical, components and therefore the final color of the product will vary. This process creates the unique beauty of each piece.
Terra cotta and earthenware are always slightly porous. Although this allows plant roots to breathe, it also constitutes a risk in winter. When the temperature drops below freezing, any water present in the pot walls will freeze and expand. This will cause the pot wall to spall and can ultimately destroy the pot. Whether this actually happens or not, depends upon the quantity of water that can be absorbed by the fired clay. This, in turn, depends upon the quality of the clay and the way it has been processed.
Machine-made terra cotta planters can absorb a lot of water and are the most vulnerable to winter damage. Hand-made containers, like those offered by Campania, absorb far less water because the clay is processed differently. They are frost-resistant if handled correctly. However, because any water held in a pot from rain or melting snow will freeze and expand, any pot made of a non-elastic material is at risk if left outside unprotected in winter. Accordingly, while the high firing temperature and quality of our glazed and terra cotta containers results in a durable and frost-resistant product, we still recommend that they be stored in a frost-free covered area in winter. If left outside, water may accumulate in the container and freeze, causing the planter to crack and break.
Steel Material Spec Sheet PDF
Zinc Material Spec Sheet PDF
Steel Planters- Campania’s Lightweight Steel planters are made of steel sheets 1.2 mm thick. If used outdoors, it is recommended that an appropriate sealer is applied to maintain the surface finish and prevent oxidation. Note, if oxidation occurs, rust may leach onto the ground surface with the potential to stain. Avoid collection of standing water in the bottom of the planter which can cause rusting and deterioration.
Zinc Planters- These planters are fire galvanized by dipping them into a hot zinc bath to protect the steel from rust. These planters are not designed for directed planting and are intended to be used with an interior grow pot or liner.
Fiberglass Material Spec Sheet PDF
Always place a Campania planter on a solid level surface and not directly on grass, soil, or an uneven surface.
Proper winter care is recommended for all Campania fiberglass planters for protection in environments with potential freeze-thaw cycles. If a planter is to be left planted over the winter, ensure proper drainage by:
(1) placing a layer of coarse gravel or other appropriate drainage material in the bottom of the container
(2) making sure the drainage holes are not blocked.
If the planter remains in contact with the ground surface over the winter, the freeze-thaw cycles may cause the planter to crack.
Cold Painted Spec Sheet PDF
Color is applied to Campania’s cold painted planters after they are fired. As such, the color is not integral to the piece as is a fully glazed planter. To maintain the integrity of the planter and prevent peeling/fading of surface color, we recommend that cold painted planters be used indoors only.
Always place any Campania product on a solid level surface.
