Is concrete partly waterproof ?

Concrete is partially waterproof, but not entirely. It has a certain level of water resistance, but it can still absorb water to some extent. The degree of water resistance depends on various factors, such as:-
1. Concrete mix design:- The type and proportion of cement, aggregates, and admixtures used.
2. Compaction and finishing:- How well the concrete is compacted and finished can affect its density and porosity.
3. Curing:- Proper curing helps to reduce porosity and increase water resistance.
4. Age:- Concrete becomes more water-resistant over time as it continues to hydrate and densify.
Concrete's water resistance is typically measured by its:-
1. Water absorption:- The amount of water that can be absorbed by the concrete.
2. Permeability:- The ability of water to flow through the concrete.
While concrete is not fully waterproof, it can be made more water-resistant by:-
1. Using waterproofing admixtures
2. Applying surface treatments or coatings
3. Ensuring proper construction and finishing techniques
4. Using specialized concrete mixes, such as waterproof concrete or high-density concrete
Even with these measures, concrete may still not be completely waterproof, especially in extreme conditions like high water pressure or prolonged exposure to water.

Sometimes, We observe that according to Site Conditions, the Acrylic Polymer with Glass Fiber mesh is the viable/suitable option according to technical and commercial aspects. But most of the time, the salesperson or structural engineers insist on costly materials like polyurethane, polyurea, or other. Why ?

There are several reasons why salespersons or structural engineers might insist on more expensive materials like polyurethane or polyurea, even when acrylic polymer with glass fiber mesh is a viable option:-
1. Lack of knowledge or experience with acrylic polymer systems
2. Familiarity and comfort with more traditional or established products (polyurethane, polyurea)
3. Higher profit margins for the salesperson or supplier
4. Over-specification or over-engineering, leading to unnecessary complexity and cost
5. Misconceptions about the performance or durability of acrylic polymer systems
6. Influence of marketing campaigns or manufacturer promotions
7. Pressure to use premium products to ensure “safety” or “reputation”
8. Limited consideration of commercial aspects or budget constraints
It's essential to have an open and informed discussion with the Salesperson or Structural Engineer, highlighting the technical and commercial advantages of acrylic polymer with glass fiber mesh. Be prepared to:-
1. Share relevant case studies or success stories
2. Provide technical data and performance specifications
3. Offer cost-benefit analyses or comparisons
4. Engage an independent expert or third-party consultant for validation
5. Negotiate and explore alternative solutions that meet the project’s requirements
The most expensive option isn’t always the best. A balanced approach considering technical, commercial, and practical aspects will lead to a more optimal solution.

Is waterproofing performance depending upon the structure conditions ?

Yes, waterproofing performance heavily depends on the structure's conditions. The effectiveness of a waterproofing system can be influenced by various factors, including:-
1. Surface preparation:- Cleanliness, dryness, and surface roughness can impact adhesion and performance.
2. Structural integrity:- Cracks, damage, or weaknesses in the structure can compromise waterproofing.
3. Material compatibility:- Incompatibility between waterproofing materials and the structure’s materials can lead to failures.
4. Drainage and slope:- Inadequate drainage or improper slope can cause water accumulation, reducing waterproofing effectiveness.
5. Environmental conditions:- Exposure to extreme temperatures, UV radiation, or chemical attacks can degrade waterproofing materials.
6. Maintenance and repair history:- Previous repairs or modifications can affect the structure’s condition and waterproofing performance.
7. Design and construction:- Original design and construction flaws can impact waterproofing effectiveness.
8. Age and wear:- Over time, structures settle, and materials degrade, affecting waterproofing performance.
9. Load and stress:- Structural stress or heavy loads can cause cracks or damage, compromising waterproofing.
10. Quality of workmanship:- Poor installation or application of waterproofing systems can lead to failures.
Considering these factors is crucial when selecting, designing, and applying waterproofing solutions to ensure optimal performance and durability.
