Professional knowledge of building waterproof, super practical!


▲ Yuguo light repair ▲ Shengyang rubber and plastic ▲ Sichuan Tongshen ▲ Yixiu Tianxia 01 basic term waterproof layer: a structural layer that can isolate water without allowing water to penetrate into the interior of the building.

Polymer cement waterproof coating: two component waterproof coating made of polymer emulsion and cement and other additives.

Application scope of basement waterproof grade: Grade I waterproof: places where personnel stay for a long time; Storage places where a small amount of wet stains will cause deterioration and failure of articles and parts that seriously affect the normal operation of equipment and endanger the safe operation of the project; Extremely important war preparedness works and secondary waterproofing of subway stations: places where personnel often move; Storage places that will not deteriorate or fail under the condition of a small amount of wet stains and parts that will not affect the normal operation of equipment and the safe operation of the project; Important combat readiness projects; Grade III waterproof: places for temporary activities; General combat readiness works; Grade IV waterproof: works without strict requirements for leakage water; Source: lanlinghuanke-.

Polymer self-adhesive membrane waterproof coiled material: it takes synthetic polymer sheet as the bottom membrane and is covered with polymer self-adhesive membrane layer on one side, which is used for pre paving the waterproof coiled material constructed by reverse adhesion method.

Grade III waterproof: there are a few water leakage points, and there shall be no wired flow and mud and sand leakage; The number of water leakage or wet stains on any 100 ㎡ waterproof area shall not exceed 7, the maximum water leakage of a single water leakage point shall not be greater than 2.5l/d, and the maximum area of a single wet stain shall not be greater than 0.3 ㎡.

Self adhesive polymer modified asphalt waterproof coiled material: it takes high polymer modified asphalt as the main material and has self-adhesive waterproof coiled material as a whole.

Additional layer: coiled material or film reinforcing layer set at the parts prone to leakage and damage.

Composite waterproof layer: a waterproof layer composed of mutually compatible coiled materials and coatings.

Thermal insulation layer: a structural layer that reduces the transfer of solar radiant heat to the room.

between two adjacent materials.

Isolation layer: a structural layer that eliminates the adverse effects of bonding force, mechanical biting force, chemical reaction, etc.

Waterproof system: a fully functional waterproof layer composed of waterproof main materials, base treatment agent, adhesive, sealing materials, mechanical fasteners, detail prefabricated parts, matrix reinforcement materials and other auxiliary materials.

Other underground works: the total wet stain area shall not be greater than 2 / 1000 of the total waterproof area; No more than 3 wet stains on any 100 ㎡ waterproof area, and the maximum area of a single wet stain is no more than 0.2 ㎡; Among them, the tunnel engineering also requires that the average water seepage shall not be greater than 0.05l / (㎡ · d), and the water seepage on any 100 ㎡ waterproof area shall not be greater than 0.15L / (㎡ · d).

It always maintains a viscous paste like waterproof coating within its service life.

Product concept non curable rubber asphalt waterproof coating: non curable rubber asphalt waterproof coating is a waterproof coating with petroleum asphalt and high molecular polymer as the main components and special additives.

Protective layer: a structural layer that protects the waterproof layer or thermal insulation layer.

Concept of basement waterproof grade: Grade I waterproof: no water seepage is allowed, and there is no wet stain on the structural surface; Secondary waterproof: water leakage is not allowed, and there can be a small amount of wet stains on the structural surface; Industrial and civil buildings: the total wet area shall not be greater than 1 / 1000 of the total waterproof area (including roof, wall and ground); There shall be no more than 2 wet stains on any 100 ㎡ waterproof area, and the maximum area of a single wet stain shall not be greater than 0.1 ㎡.

Elastomer modified asphalt waterproof coiled material: it is a curlable sheet waterproof material made of styrene butadiene styrene (SBS) thermoplastic elastomer as modifier, polyester tire base cloth as reinforcing layer, and polyethylene film (PE), fine sand (s) and mineral aggregate (m) as isolation materials on the surface.

Compatibility: the performance that two adjacent materials do not produce harmful physical and chemical effects on each other.

Double Head Lifting Pin Anchor

Grade IV waterproof: there are a few water leakage points, and there shall be no wired flow and mud and sand leakage; The average water leakage of the whole project shall not be greater than 2L / (㎡ · d); The average water leakage on any 100 ㎡ waterproof area shall not be greater than 4L / (㎡ · d).
