Key Points for Geotextile Field Construction

Please note the following points when performing field construction with geotextiles:

1. During installation, avoid pulling too tightly, especially at the slope position. Overstretching can cause cracking in the area of contact and affect durability; ensure the number of seams is minimized to reduce misalignment possibilities and allow stress to be transferred to the long fiber yarns. 2. When overlapping connections, the overlap width should be 30 cm (narrower is acceptable under this condition). Cut through the top layer halfway to ensure it can bear future loads without stretching the edges too tightly or tearing. 3. Lay the reinforced polyester paste as vertically as possible relative to the base surface, making it straight. The direction of the lay must align with the direction of drainage. When cutting and piecing with needles, pay attention to controlling the length of the tails. 4. Choose to construct when the temperature is rising, with a minimum of 10℃ but not so high that it causes the PE non-woven liner to char and become brittle. 5. Use machinery to trim the preformed concrete bags neatly, which ensures a flat, even surface for the impermeable layer and improves aesthetics. 6. Leave a natural settlement effect of 2% to 5% to prevent phenomena such as bulging or relaxation and detachment. 7. Keep the construction site clean and free of debris, dust, and other杂物. 8. Ensure thorough protection work is done before completion to prevent damage from vehicle traffic. 9. In poor weather or excessive humidity, cover the site to maintain construction quality and protect finished products from contamination. This is some advice on the precautions for the application of geotextiles, for your reference. Hope it is helpful!
