膨れ現象が多く発生する等の欠点を有していた。Traditionally, in coating film waterproofing, in which a coating layer made of an appropriate material is formed on a waterproof base surface such as a concrete layer, the coating layer is adhered to the waterproofing base basin using the violet adhesive rule. Cracks in the waterproof base cause follow-up cracks in the paint film layer, and free moisture contained in the waterproof base becomes water vapor due to temperature rises on Sundays, etc., and accumulates between the waterproof base and the paint film layer, causing the paint film to deteriorate. The coating layer had to be peeled off from the waterproof base, which caused many blistering phenomena between the coating layers.

When it comes into contact with water, the backing paper immediately dissolves and the gel-like bentonite adheres directly to the waterproof base in a short time, creating a complete water-blocking layer and ensuring that water does not leak out from the joints between the waterproof sheets. It is to be made possible.

Water-absorbing nonwoven fabric using water-absorbing fibers such as excellent polyester synthetic resin or heat-resistant aromatic polyamide-based or aromatic co-polyamide-based synthetic resin 2
The fruit-like refined bentonite 4 is held uniformly between five layers of water-soluble paper or water-soluble film 3 to form an integrally formed sheet.

The three layers were needle-punched to entangle the fibers to form a uniform sheet, so the waterproof sheet body 1 was placed with the water-absorbing nonwoven fabric 2 facing upward at the interface with a waterproof base such as a concrete layer. Next, when the water-soluble paper or water-soluble film 3 on the back side of the waterproof sheet body 1 comes into contact with water, the water-soluble paper or water-soluble film 3 immediately dissolves and gel-like bentonite 4 adheres directly to the waterproof base interface in a short time. It is something that forces you to do something.

となるのである。:Effects of the Invention] In short, the present invention maintains bentonite 4 uniformly between the layers of water-absorbent nonwoven fabric 2 and water-soluble paper or water/8-based film 3, and forms the three layers integrally to form a sheet. As a result, when the backing paper comes into contact with water at the waterproof substrate interface, the backing paper immediately dissolves and the del-shaped bentonite adheres directly to the waterproof substrate in a short time, creating a complete water-blocking layer and bonding the waterproof sheets together. It also makes it possible to ensure continuous water supply in certain parts of the building, and it also makes it possible to carry out focused local waterproofing without having to carry out continuous waterproofing over the whole area, such as at concrete joints on the outer walls of basements.

に的確に付着せしめらη、るのである。In addition, the water-absorbing nonwoven fabric 2 formed on the surface allows a large amount of water to be retained within the water-absorbing fibers, and the bentonite 4
This makes it possible to ensure uniform swelling of the water-absorbing fibers, and also allows the bentonite 4 in the form of kelp to adhere precisely to the waterproof base interface due to the water-absorbing expansion pressure of the water-absorbing fibers themselves.

せしめろれる等その実用的効果甚だ大なるものである。In addition, until the gel-like bentonite 4 completely blocks the many water paths, the water-absorbing nonwoven fabric 2 itself can sufficiently exhibit its water-blocking properties, and the particles are held by the entanglement of the fibers, resulting in a uniform flow. The practical effects of this, such as swelling and preventing the progression of kelp formation, are tremendous.
