Mortar composite waterproof concrete additive
Product origin China
Delivery time 3-15 days
1. Anti-seepage and moisture-proof.
It is used for the anti-seepage and moisture-proof treatment of the surface of the main structure to form a rigid waterproof layer.
2. Pressure-resistant and tensile strength.
The initial setting time is greater than 50min, the final setting time is less than 4h, the bonding force is greater than 1.0MPa, and the pressure-resistant and tensile strength is increased by 20%-30%.
3. Good stability.
When the blending usage is 3-5% of the cement, the volume stability is the best.
Mortar composite waterproof concrete additive (LV-2)
Mortar composite concrete roof waterproofing (LV-2)
LV-2 composed mortar concrete block waterproofing is a composite solution composed of
inorganic aluminum salt as the main body and a variety of inorganic salts.
LV-2 composed mortar waterproofing concrete walls is mixed into concrete or cement mortar
to prepare waterproof concrete or waterproof mortar with anti-seepage, anti-leakage and
moisture-proof functions, and construct a rigid waterproof layer on the surface of the building

- Clean basement
The basement should be cleaned and moistened. If the basement is smooth and needs to be shaved,
the pitted surface rate shall not be less than 75%.
- The treatment of waterproof plain layer
Brush a line of cement waterproofing agent paste evenly on the base layer as the bonding layer,
and the thickness is preferably 2mm.
- The treatment of the first layer of waterproof mortar
Before the bonding layer is dry, brush the first layer of waterproof mortar as a leveling layer in time
with a thickness of 10mm. After pressing, the pitted surface is able with wooden cloth.
- The treatment of the second layer of waterproof mortar
Make the second layer of waterproof mortar in time after the initial setting of the leveling layer with
a thickness of 10mm as the appropriate thickness, and compact it for smoothness.
- Wet maintenance
After the second layer of waterproof mortar is finally set, it shall be cured in a humid condition for 7 days in time.
- Anti-seepage and moisture-proof works on the surface of any structure.
- Underground engineering: basement, underground air defense.
- Water conservancy and hydropower: pools, dams, water towers.
- Rail transit: tunnels, bridges.
3 years. LV-2 block wall waterproofing can still be used over shelf life but passed the inspection.
