"Just have it in mind. Do you have anything else? I'll be back in a minute! Do you want me to bring a message to your parents?"

"Uncle Tian, ​​are you leaving now? Can you leave after dinner?"

"No, it's getting late. If it's later, it'll be dark and it's hard to walk!"

"Oh, by the way, Uncle Tian, ​​please take these two buckets of loaches back! One bucket for you, and please send another bucket back to my mother!"

"Oh, this loach is really good! It's hard to buy such a big loach in Quanshui City!" Uncle Tian took a look into the tin bucket and said with a smile.

"Wait a minute!"

Yu Qingyang ran to find two pieces of plastic sheeting, wrapped the mouth of the tin bucket, and tied it with a rope, fearing that the loach would be suffocated to death, and poked a few small holes in the plastic sheeting.

Then he carried it to Uncle Tian and loaded it into the car.

Uncle Tian left, and so did Sun Gong and the others.

Yu Qingyang arranged for workers to start laying geotextile.

A layer of waterproof geotextile should be laid between the concrete slope protection and the soil slope foundation.

The formwork can only be supported after laying the geotextile.

For the tooth wall below, the criss-crossing floor beams in the middle are fifty centimeters thick, the underground trench is buried twenty centimeters deep, and the concrete slab is twenty centimeters thick, so the final floor beams are ten centimeters higher than the concrete slab.

This extra ten centimeters needs to be shaped using a template.

"Brother Yu, what's that white one?" Xiao Shen approached Yu Qingyang and asked in a low voice.

"That is geotextile, it is used for waterproofing! Although concrete is waterproof, it cannot be 100% waterproof!

So add a layer of waterproof geotextile to make it waterproof!”

"Waterproof geotextile? Are there non-waterproof geotextiles?" Xiao Jiang also asked.

"Yes, geotextiles are divided into two types: waterproof geotextiles and permeable geotextiles.

Their functions are different!

As the name suggests, waterproof geotextile is used for waterproofing!

Permeable geotextile is used to prevent soil loss!

It means that water can pass through the geotextile and block the soil." Yu Qingyang explained carefully.

"Brother Yu, what is the difference between waterproof geotextile and permeable geotextile? How to tell the difference?"

"Look, there is a waterproof membrane behind this waterproof geotextile! The permeable one does not have this waterproof membrane!"

"Stop! You can't connect like this!" Yu Qingyang suddenly shouted to stop.

"What's the matter, little boss? Is the overlap of twenty centimeters correct?" The worker looked at Yu Qingyang doubtfully.

Yu Qingyang was not in a hurry. He walked down the embankment and explained to them carefully, "I blame you for not explaining it clearly. It is correct to overlap by twenty centimeters, but it cannot be overlapped like this. The geotextile on top must be used to press the geotextile below.

.”

"Brother Yu, is there no difference? They are all overlapped by 20 centimeters, up and down, down and up, aren't they all the same?" Xiao Shen also followed Yu Qingyang down the slope. After listening to Yu Qingyang's words, he asked doubtfully
