How to lay the foundation of artificial turf in playground?
Laying artificial turf in a playground is not just a matter of surface beauty, but more importantly, it is to build a stable, well-drained and durable foundation system. A professional foundation can not only extend the life of the lawn, but also ensure safety in use.
1. Why is the foundation so important for artificial turf in a playground?
The playground is densely populated and frequently used, and the lawn needs to withstand greater pressure. If the foundation is not solid, the lawn is prone to sinking, water accumulation and even wrinkling, affecting the appearance and service life. Therefore, building a reasonable foundation structure is the prerequisite for ensuring the overall paving effect.
2. What are the common base materials?
The following are three base materials widely used for laying artificial turf:
Crushed stone layer: It has good structural stability and drainage capacity and is the most common base material. A solid support layer can be formed by compaction.
Decomposed Granite: A natural material that is durable and has natural drainage, suitable for playgrounds designed for natural environments.
Washed Concrete Sand: Uniform particles, compact structure, and both drainage and load-bearing performance.
These materials are usually used in combination, and are reasonably combined according to the project terrain and budget.
3. How to lay and compact the base material?
The laying steps are as follows:
Site cleaning and leveling: Remove the original turf and debris to keep the surface flat.
Laying base materials: Lay gravel/granite/sand and gravel according to project requirements, usually with a thickness of 5-15cm.
Compaction: Use a vibrating compactor to compact to ensure density and stability to avoid later settlement.
High-quality compaction can greatly improve the impact resistance and stability of the lawn.
4. Drainage design cannot be ignored
A good drainage system can prevent the lawn from being soaked and deformed. To this end, it should be ensured that:
The base material has good water permeability;
The ground is set with a slight slope (1-2% slope) to facilitate the drainage of rainwater;
If necessary, set up a concealed pipe or seepage trough system to improve drainage efficiency.
5. Weed Barrier and subsequent structure laying
Lay weed barrier on the compacted layer to prevent weeds from penetrating the lawn and improve durability. Then proceed with the bonding, cutting, stitching and filling of artificial turf.
6. Regular maintenance to ensure long-term use
Even if the foundation quality is excellent, it still requires later maintenance:
Check whether there is settlement or water accumulation;
If the base is found to be sunken, it should be repaired in time;
Regularly clean the drainage ditch and lawn surface to keep the function intact.
Summary
A stable and well-drained foundation is the basis for the long-term use of artificial turf in playgrounds. Choosing suitable base materials (such as gravel, weathered granite, washed sand), and scientifically compacting and laying weed barrier can significantly improve the service life and safety performance of the lawn. With daily maintenance, it will bring users a more comfortable and safe activity environment.
