Yes, it is possible to drill into concrete even if there is a steel grid embedded within it. However, drilling through steel can be more challenging and may require specialized tools such as carbide-tipped masonry bits or diamond-tipped core drills. It is important to use the appropriate equipment and techniques to effectively drill through both the concrete and steel grid. Additionally, drilling through steel may cause the drill bit to wear out faster, so it is advisable to have extra bits on hand. **

Yes, you may compact the concrete slabs. Compacting the slabs will help to ensure that they are properly settled and will provide a more stable foundation. However, it is important to use the appropriate compaction equipment and techniques to avoid damaging the slabs. Additionally, it is important to follow any specific guidelines or recommendations provided by the manufacturer or engineer to ensure the best results. **

To apply concrete on concrete, the existing surface must be clean, free of debris, and properly moistened. A bonding agent or primer should be applied to the existing concrete to ensure adhesion. The fresh concrete mix can then be poured or pumped onto the existing surface and spread evenly using a screed or trowel. It is important to properly cure the new concrete to prevent cracking and ensure a strong bond between the two layers. **

Yes, it is possible to pour new concrete over old concrete as long as the existing concrete is in good condition and properly prepared. The old concrete should be clean, free of any loose debris, and roughened to provide a good bonding surface for the new concrete. Additionally, a bonding agent may be used to ensure a strong bond between the old and new concrete. It is important to consult with a professional to assess the condition of the existing concrete and determine the best approach for pouring new concrete over it. **

Yes, there are tiny house settlements in the German-speaking area, particularly in Germany and Austria, that live off-grid in the forest. These settlements are often established by individuals or communities seeking a more sustainable and self-sufficient lifestyle. Living off-grid in the forest allows residents to rely on renewable energy sources, practice sustainable living, and be closer to nature. These settlements often prioritize eco-friendly practices and minimal environmental impact. **

For setting lawn edging stones, garden concrete would be the better option. Garden concrete is specifically designed for outdoor use and is more durable and weather-resistant than concrete screed. It also has better adhesion properties, making it more suitable for securing the edging stones in place. Additionally, garden concrete is often formulated to be more resistant to cracking and shifting, which is important for maintaining the integrity of the lawn edging. **

To repair a concrete house from Dennert, one can start by assessing the extent of the damage. Small cracks can be filled with a concrete patching compound, while larger cracks may require professional help. It is important to clean the damaged area thoroughly before applying any repair material. Additionally, applying a waterproof sealant or coating can help prevent future damage and prolong the life of the concrete house. **

Around 1890, Portland cement was the most commonly used concrete in house construction. This type of concrete was widely available and offered a strong and durable material for building foundations, walls, and other structural elements. Portland cement concrete was also used in combination with other materials such as bricks and stones to create a variety of architectural styles popular during that time period. Its widespread use contributed to the growth of urban and suburban development during the late 19th century. **
