Over my years exporting geosynthetics, I’ve seen buyers skip the filter fabric to save a few dollars, only to watch their entire coastal defense wash away a year later. Let’s look at how to get this right in real-world projects.

1. Menene Riprap kuma Me yasa Amfani da Geotextile?

Masu saye sukan zo wurina suna mai da hankali kacokan akan samo manyan duwatsun sulke mafi nauyi da za su iya.

4. Yadda Ake Zaɓan Madaidaicin Geotextile don Riprap

Choosing the correct material is the most important decision you will make. I regularly help contractors avoid disaster by adjusting their material specs. If the fabric is too weak, the rocks will punch through. If the pores are too small, water won’t drain.

Anan ga mahimman sigogin da dole ne ku tantance:

Nauyi (gsm / oz)
