近年來，房屋修繕工程中的補強技術受到關注，尤其是地下室及地坪等結構的維修。在補強過程中，epoxy和pu等新型材料被廣泛應用。
epoxy是一種具有優異黏附性和耐化學侵蝕能力的材料，可用於補強結構裂縫，提高結構強度。pu則是一種彈性較好的聚氨酯材料，能夠有效填充結構空隙，提升結構的耐久性。
在補漏方面，epoxy和pu材料也可用於抓漏工程。提前進行地下室的抓漏工作，能夠有效避免潮濕及漏水對結構造成的損害。
除了材料的應用外，伸縮補強技術也是近年來的新發展。通過安裝中間樁等結構元件，能夠增強結構的承重性能，提升房屋的安全性。
綜上所述，epoxy和pu等新型材料的應用，以及伸縮補強技術的發展，為房屋修繕工程帶來了更多可能性，提升了結構的強度和耐久性。

標題: Strengthening House Structures: Application of New Materials Technology
In recent years, the reinforcement technology in house repair projects has gained attention, especially in the repair of structures such as basements and floors. During the reinforcement process, new materials like epoxy and pu are widely used.
Epoxy is a material with excellent adhesion and chemical corrosion resistance, which can be used to reinforce structural cracks and improve structural strength. Pu is a flexible polyurethane material that can effectively fill structural voids and enhance durability.
In terms of leak repair, epoxy and pu materials can also be used in leak detection projects. Conducting leak detection in basements in advance can effectively prevent damage caused by dampness and water leakage to the structure.
In addition to material application, the development of expansion and contraction reinforcement technology is also a new trend in recent years. By installing structural components such as intermediate piles, the bearing capacity of the structure can be enhanced, improving the safety of the house.
In conclusion, the application of new materials such as epoxy and pu, as well as the development of expansion and contraction reinforcement technology, has brought more possibilities to house repair projects, enhancing the strength and durability of structures.
