Packer
Each company offers its own types of packers.
The type where only moisture seeps out, the type that uses only the free-length section, and the type that tears easily but is inexpensive.
There are also different sizes available for the bore diameter.
The price is for the 90mm type,1,000 yen/m to 6,000 yen/m There is a price difference of about that much.
Span Seal
It is also known as butyl rubber, and you wrap it around the opening of the packer to use it.
It's soft and pliable, stretches a bit, and can be easily shaped.
However, it feels sticky when you touch it.
This product is also used to bond car windshields.
Prices vary depending on the diameter and thickness. Generally speaking,1 roll (4 m) 1,000–3,000 yen That's about it.
Paper Ribbon
It's the tape used to secure medical gauze and bandages, isn't it?
After placing the packer over the anchor, secure it by winding it spirally from the tip of the anchor body.
Doing this eliminates slack in the packer, making it less likely to snag when inserting the casing, and
It also prevents the packer from getting snagged on the surrounding rock when the casing is pulled out, thereby protecting the packer from damage.
Some people use vinyl tape for this. It's not a bad option, but depending on the location, the tape might not hold.
When using vinyl tape, it's best to make a clean cut before using it.
1 box: 150–200 yen
Zip Ties (Cable Ties)

There are various levels of strength, and while it’s best to choose the strongest option possible, that can result in the product being too thick or too expensive, so,
I think it's better to use thin, inexpensive items in two or three layers.
100-pack: 500–2,000 yen (Prices vary by type)
The 4-bun hose you normally use is sufficient for the injection hose.
See you later.
