Waterproofing and water resistance.
Waterproofing and water resistance are related but distinct concepts in construction and material science:-
Waterproofing:-
– Refers to the ability of a material or system to prevent water penetration entirely.
– Typically achieved through the use of impermeable materials, membranes, or coatings.
– Designed to withstand hydrostatic pressure and keep water out completely.
– Typically achieved through the use of impermeable materials, membranes, or coatings.
– Designed to withstand hydrostatic pressure and keep water out completely.
Water Resistance:-
– Refers to the ability of a material or system to resist water penetration to some extent.
– May allow some water to pass through, but minimizes the amount and slows down the process.
– Often achieved through the use of water-repellent materials, treatments, or coatings.
– May allow some water to pass through, but minimizes the amount and slows down the process.
– Often achieved through the use of water-repellent materials, treatments, or coatings.
In summary:-
– Waterproofing aims to prevent water penetration entirely.
– Water resistance aims to minimize water penetration.
– Water resistance aims to minimize water penetration.
Both are important in construction, depending on the specific application and requirements. Waterproofing is critical in applications like tanks, swimming pools, and basements, while water resistance is sufficient for applications like walls, roofs, and facades.
After Pressure Grouting with Acrylic Polymer mixed with Cement in the Basement, does 2 coats of Acrylic Polymer coating be required immediately ?
In a Basement setting, applying two coats of Acrylic Polymer coating immediately after pressure grouting with acrylic polymer mixed with cement may be beneficial for added protection and durability.
Basements are prone to moisture and humidity, so the additional coating layers can help:-
1. Enhance water resistance:-
Provide an extra barrier against water seepage and humidity.
2. Improve durability:- Increase the lifespan of the grouted area by protecting it from the harsh basement environment.
3. Reduce maintenance:- Minimize the need for future repairs and maintenance.
2. Improve durability:- Increase the lifespan of the grouted area by protecting it from the harsh basement environment.
3. Reduce maintenance:- Minimize the need for future repairs and maintenance.
However, ensure:-
1. Compatibility:-
Confirm the grout and coating are compatible.
2.Thin coats:- Apply thin layers (about 0.5 mm each) to avoid overloading the grouted area.
2.Thin coats:- Apply thin layers (about 0.5 mm each) to avoid overloading the grouted area.
By applying two coats of acrylic polymer coating immediately, you’ll provide added protection and peace of mind for the basement area.
G+18 Highrise Building. We Observe that from the 16th floor to the 7th floor, there are lots of cracks of the Outside AAC Block Wall Structure. Is there any chance at the Rainy Season that Water can Travel Inside the Room and Create Seepage, Dripping Water or Damp from slabs ?
Yes, there is most possibility of water ingress and seepage into the rooms through the cracks in the AAC block wall structure, especially during the rainy season. Here's why:-
1. Water penetration:-
Rainwater can seep into the cracks and enter the wall cavity, potentially reaching the inner slabs and walls.
2. Capillary action:- Water can travel through the cracks and walls via capillary action, which can lead to dampness and seepage.
3. Gravity:- Water may flow downwards from the upper floors to the lower floors, increasing the risk of seepage and dripping water from slabs.

3. Gravity:- Water may flow downwards from the upper floors to the lower floors, increasing the risk of seepage and dripping water from slabs.
To mitigate this risk, consider the following:-
1. Crack repair:-
Seal the cracks in the AAC block wall structure with a suitable waterproofing material, such as a polymeric sealant or a cement-based grout.
2. Waterproofing coating:- Apply a waterproofing coating to the exterior of the AAC block wall to prevent water penetration.
3. Drainage system:- Ensure a proper drainage system is in place, including functional rainwater gutters and downspouts, to direct water away from the building.
4. Regular maintenance:- Regularly inspect and maintain the building’s exterior and interior to identify and address any potential water ingress points.

Can we Waterproof the Base of the Pipes with Acrylic Polymer mixed with Cement from both sides ?
Yes, we can use Acrylic Polymer mixed with Cement to waterproof the base of HDPE or UPVC pipes. This mixture, known as a polymer-modified mortar, offers improved waterproofing properties compared to traditional cement. The acrylic polymer enhances the mortar’s flexibility, adhesion, and resistance to water and chemicals.
When using acrylic polymer mixed with cement, keep the following points in mind:-
1. Proper surface preparation:-
Clean and prepare the pipe surface before applying the mortar.
2. Apply a suitable thickness:- Apply a sufficient thickness of the mortar to ensure effective waterproofing.
3. Curing and drying:- Allow the mortar to cure and dry according to the manufacturer’s recommendations.

By using acrylic polymer mixed with cement, we can create a durable and Waterproof Seal around the Base of the Pipes, providing added protection against water ingress.
