1, roof waterproof;

2, underground waterproof;

3, indoor, toilet bath waterproof;

4, external wall waterproof; Exterior wall elevation, slope, windowsill, column edge, etc.

5, special construction (structure) building waterproof; Such as: water tower, swimming pool.

 

(2) Classification by means of fortification

1, composite waterproof. Rigid and flexible combination, multi - channel waterproof, comprehensive treatment.

2, the structure is self-waterproof.

 

(3) Classification according to the performance of fortification materials

1, rigid waterproof.

The use of mortar, cement slurry, waterproof mortar composed of waterproof layer.

2, flexible waterproof

(1) coil waterproof; Several layers of coil are glued to the structural layer with cementing material, and constitute a waterproof layer. Often used for roof, underground waterproof engineering.

It is divided into three categories: modified asphalt coil, self - adhesive waterproof coil, non - asphalt waterproof coil.

(2) coating waterproof;

Waterproof coatings mainly include: polyurethane, K11, JS, penetration crystallization and other waterproof materials.

Construction is simple and widely used.

 

(4) Classification according to the variety of fortification materials

Coil waterproof, coating waterproof, sealing material waterproof, concrete waterproof, powdery hydrophobic material, penetrant waterproof.
