FAQs

What is CONCREED ?

CONCREEDis a well-known and highly trusted construction chemicals firm in India that produces a wide range of goods, such as concrete admixtures, waterproofing chemicals, tile adhesives that are ready to use, and chemicals for underfloor finishing and undersurface treatment.

Waterproofing

1. What is waterproofing in construction?

Waterproofing involves applying materials or systems to prevent water penetration into structures, protecting them from moisture damage, leaks, and deterioration.

2. What are the common types of waterproofing methods?

Common methods include liquid waterproofing membranes, bituminous coatings, cementitious waterproofing, and polyurethane-based systems, each suited for specific applications like roofs, basements, or bathrooms.

3. How long does waterproofing last?

The lifespan depends on the material and application quality, typically ranging from 5 to 10 years. Regular maintenance and inspections can extend durability.

Admixtures

4. What are admixtures in concrete?

Admixtures are chemicals or additives mixed into concrete to enhance properties like workability, strength, setting time, or durability.

5. What are the types of admixtures?

Common types include plasticizers (improve workability), accelerators (speed up setting), retarders (slow setting), and air-entraining agents (improve freeze-thaw resistance).

6. Can admixtures affect concrete strength?

Yes, certain admixtures like superplasticizers can enhance strength by improving workability and reducing water content, while improper use may weaken the mix.

Mortars

7. What is the difference between cement and mortar?

Cement is a binding material, while mortar is a mixture of cement, sand, and additives used for bonding bricks, stones, or tiles.

8. How do you choose the right mortar mix?

Selection depends on the project’s structural requirements, environmental conditions, and the materials being bonded, such as bricks or concrete blocks.

Tile Adhesives/Grouts

9. What is tile adhesive, and how is it different from mortar?

Tile adhesive is a specialized, often polymer-modified, cement-based or epoxy-based product designed for bonding tiles, offering better adhesion and flexibility than traditional mortar.

10. Can tile adhesive be used on all surfaces?

No, the adhesive type must match the surface and tile material (ceramic, porcelain, or natural stone) for optimal performance.

11. How long does tile adhesive take to set?

Setting times vary, typically 24–48 hours for cement-based adhesives, but fast-setting options can be ready in 4–6 hours.

12. What is the purpose of grout in tiling?

Grout fills gaps between tiles, providing structural stability, preventing water seepage, and enhancing aesthetic appeal.

13. How do you maintain grout to prevent staining?

Regular cleaning with mild detergents, sealing grout lines every 1–2 years, and avoiding harsh chemicals help maintain grout and prevent stains or mold.

Thermal Active Coatings

14. What are thermal active coatings?

These are specialized coatings that reflect or manage heat, reducing energy costs by maintaining indoor temperatures, often used on roofs or exterior walls.

15. How do thermal active coatings work?

They reflect solar radiation, reduce heat absorption, and may include insulating properties to minimize heat transfer, improving energy efficiency.

16. Are thermal active coatings environmentally friendly?

Many are eco-friendly, reducing energy consumption and cooling costs, but the environmental impact depends on the coating’s chemical composition and production process.
