Advantages of Natural Stone Umpak
Strength and Durability
Mount Merapi stone, lava stone, and andesite have high compressive strength. This material is resistant to extreme weather, rain, heat, and humidity. In fact, it does not easily crack or weather even for decades.
Protects Wooden Pillars
Furthermore, the wooden pillars that you place on the umpak do not touch the wet ground. The pillars are protected from termites, fungi, and decay. As a result, the lifespan of the wooden building becomes longer.
Natural and Traditional Aesthetics
Meanwhile, the natural colors of stone provide a warm and ethnic impression. Options include white, gray, black, brown, to brick red. Not only that, this material is suitable to be combined with ulin wood, teak, or Borneo wood.
Environmentally Friendly
Moreover, natural stone does not require chemical processes. We carry out excavation and cutting responsibly. Therefore, this product is truly environmentally friendly.
Easy Maintenance
Basically, you only need to occasionally clean the umpak from moss. If you want it to be neater, you can coat it with water repellent.
Practical Plain Flat Model
Another advantage, the flat top surface makes it easy to place wooden pillars. You do not need to re-chisel. Meanwhile, the wider bottom side (30 cm) provides stability on the ground or floor.
Ideal Applications
Generally, this stone umpak is very suitable for various purposes. For example:
– Tropical colonial buildings with wooden structures
– Wooden terrace pillar foundations for villas or resorts
– Restoration of cultural heritage buildings (replacement for original umpak)
Usage Guide
First, make sure the ground or base floor is solid and level. Second, place the stone umpak with the bottom side (30 cm) on the ground. The top side (20 cm) faces upward. Third, place the wooden pillar exactly in the center of the top surface of the umpak. Finally, add a waterproof layer or thin plaster between the wood and the stone. This step prevents water seepage.
