25 square meters 5m x 5m composite decking construction cost: the secret of 600-800 US dollars
In modern society, composite decking has gradually become the first choice of floor decoration materials with its environmental protection, beauty and durability. Today, let’s take a detailed look at the construction process of 25 square meters (5 meters * 5 meters) composite decking on concrete ground and its material cost.
1. Introduction to composite decking

Composite decking is a new type of environmentally friendly composite material made of wood powder, plastic and additives through high temperature and high pressure. It combines the advantages of wood and plastic. It not only has natural wood texture and texture, but also has good corrosion resistance, wear resistance, UV resistance, and aging resistance. In addition, composite decking is also fireproof, moisture-proof, and insect-proof, making it an ideal choice for floor decoration.
2. Construction process of 5m x 5m composite decking
1. Ground treatment: Before construction, first ensure that the concrete ground is flat, dry and clean. For uneven areas, cement mortar is needed for leveling.
2. Laying moisture-proof mat: Lay a moisture-proof mat on the leveled ground to prevent ground moisture from affecting composite decking.
3. Laying keels: Lay keels on the moisture-proof mat, and the keel spacing is generally 30-40 cm. The function of the keel is to fix the composite decking and ensure the stability of the floor.

4. Laying composite decking: Lay the composite decking on the keel, pay attention to the joint gap, and ensure that the floor is laid neatly.
5. Edge treatment: Perform edge treatment around the floor and at the door to make the floor fit tightly with the wall, door and other parts.
6. Cleaning the site: After the construction is completed, clean the site in time to ensure that the ground is clean and tidy.
III. Material cost of 5m x 5m composite decking
1. Composite decking: The material cost of 5m x 5m composite decking is about 600-800 US dollars. The specific price varies depending on factors such as region, brand, and material.
2. Moisture-proof mat: The price of moisture-proof mat is relatively low, generally around 1-2 US dollars per square meter.
3. Keel: The price of keel is about 1-2 US dollars per keel, calculated according to the spacing and number of keels.

4. Auxiliary materials: Auxiliary materials such as glue and edge strips cost about 1-2 US dollars per square meter.
Based on the above costs, the material cost of 5m x 5m composite decking is between 600-800 US dollars.
4. Summary
The material cost of 5m x 5m composite decking on concrete ground is between 600-800 US dollars. Compared with other floor decoration materials, plastic wood has the advantages of environmental protection, beauty, and durability, and is an ideal choice for floor decoration. Through the detailed introduction of this article, I believe that everyone has a more comprehensive understanding of the construction process and cost of composite decking. In actual construction, please be sure to choose a regular construction team to ensure construction quality.
