Waterproof Mortar

Q: What are the functions of waterproof mortar?

1.Prevent wall seepage Waterproof mortar is mainly used in the waterproof treatment of building walls. It can effectively prevent water seepage, enhance the water resistance of walls, prevent water seepage, and protect the structure and stability of buildings. 2.Prevent ground water seepage In basements, bathrooms, kitchens, and other places, the ground is often susceptible to water erosion, leading to water seepage. The use of waterproof mortar can effectively enhance the water resistance of the ground, prevent water seepage, and thus improve the service life of buildings. 3.Prevent pollution In cities, building surfaces are often susceptible to factors such as air pollution and road dust, leading to surface pollution. The use of waterproof mortar can effectively prevent surface pollution of buildings and improve their aesthetic appeal.

Challenges in Applying Waterproof Mortar

Excellent waterproof mortar features good weather resistance, durability, and impermeability. However, various problems often occur in practical applications:

Affecting cement hydration and reducing strength
Prone to leakage under water pressure
Difficult to apply or easy to sag
Prone to hollowing or peeling
Susceptible to aging, cracking, or chemical corrosion

These issues are usually caused by inappropriate product formulations. Celotech provides professional solutions to help waterproof mortar avoid the problems outlined above.

Celotech Waterproof Mortar Solution

High-performance waterproof mortars typically require the synergistic effect of multiple additives:

Cellulose ethers: Provide excellent water retention, workability, and adhesion, forming the foundation of the mortar system.
Redispersible polymer powder (RDP): Improves flexibility, bond strength, and crack resistance, while enhancing waterproofing.
Superplasticizer: Improves fluidity, reduces water usage, and thus increases mortar strength.
Defoamers: Eliminate air bubbles, increasing density and final strength.
Water-repellent agents: Impart excellent hydrophobic properties to the mortar, improving overall impermeability.

Recommended Waterproof Mortar Formulation

Additive types	Function	Recommended Model
Hydroxypropyl Methyl Cellulose (HPMC)	Improves water retention and workability	Celopro® MK50M FP / Celopro®ME50M P
Redispersible polymer powders	Enhances flexibility and crack resistance	Vinabond® H517 / Vinabond®H518
Superplasticizer	Improves flowability and reduces water demand	Ultraplast® SM11
Defoamers	Eliminates air bubbles and improves density	Foamsolver® DF03
Water-repellent agents	Provides water repellency and improves impermeability	Aguago® WP200

Note: The above are general recommendations. Specific recommendations need to be optimized based on the raw material system and construction conditions. It is recommended to conduct experimental verification in advance.

Our Solution Advantages

The formulation focus can be flexibly adjusted to meet different construction needs:

For scenarios requiring long-term immersion or high waterproofing: Strengthen the water-repellent system to improve the overall impermeability.
For vertical or high-altitude construction: Optimize the cellulose ether ratio to improve construction stability.
Substrate prone to deformation or cracking: Increase the proportion of latex powder to improve ductility and crack resistance.
For high-strength structures: Control the water-cement ratio and use water-reducing agents appropriately to improve density.

Through targeted adjustments, the optimal balance between construction efficiency and durability can be achieved in different environments.

Application Areas

Underground space waterproofing and leakage repair.
Building roof waterproofing layer construction.
Various water storage structures (such as water tanks, swimming pools).
Indoor damp areas (kitchens, bathrooms).
Tunnels, civil defense facilities, and industrial facilities.
