Post caps, top slabs - properties
| Variety overview |
Why just our products?
Owing to natural materials, ecological production, simple application, long life and low price, these elements convincingly compete with all similar concrete, metal or plastic products, having all the prerequisites for wide use in garden and minor building architecture.

Application
Ceramic top slabs and post caps (“elements”) are produced especially to cover garden walls, posts, plinths or garden architectural elements built from facing bricks. The formats of individual elements were defined to meet the various dimensions of facing bricks. Of course, the covering elements can also be used with other building materials, matching them always perfectly.

Assign the suitable type of top slab or post cap to the actual facing brick size and the actual post or plinth structure type, using the tables provided. You are always invited to contact us for assistance.

Element characteristics
Ceramic covering elements are produced from a mixture of natural clays and kaolin by pouring it in different moulds. Poured moulds are dried slowly in controlled drying furnaces so as to prevent the occurrence of surface cracks during drying shrinkage.

After drying, the elements are sprayed with engoba, which is a mixture of colouring agents and the natural clayey materials used to produce the elements. They are therefore absolutely ecological colouring materials, “baked” into the body during the firing process.

Engobas will neither flake off nor lose colour richness over time. Matt engobas are applied as a standard, while glossy ones are for extra payment. The covering elements are produced in three basic colour versions: Old grey, brick red and beige.

Do not forget to specify the colour you require in your order.

Element physical properties
   Absorbability and frost-resistance are the most important physical properties of the elements. Given that the covering elements are not loaded in pressure and shear, pressure and shearing strength is neither relevant nor monitored.

When fired in chamber gas furnaces under temperatures exceeding 1000 °C, ceramic materials sinter and achieve the absorbability value under 3 %. Frost-resistance of covering elements is monitored during up to 100 freezing cycles, exceeding the required value several times.

   The warranty provided for frost-resistance is 10 years.

Practical hints
Always add approximately 20 mm of the curved dripping edge to the clear dimensions of the elements on both sides. The edges are provided with dripping slots on the bottom side not to allow water to flow over the post or wall surfaces and not to form stains after drying. The same applies to sills.

Ceramic covering elements are laid on a mortar mixture used to build the facing masonry. If the covering elements are used for other building materials than facing bricks, flexible cements or, in case of necessity, standard building mortars can be used.
