Have any questions? We’re here to help you out.

What are the causes of water leakage in concrete? How can it be resolved?

Concrete leaks due to various factors are divided into two parts: external and internal. External factors relate to the concrete’s environment. The internal factors involve the concrete’s structure and materials.


– External

Water can infiltrate concrete structures through various means. It becomes an issue due to the following reasons:


1. Excessive external pressure causes water infiltration.


2. Capillary action of delicate pores within the concrete.


3. A combination of both external pressure and capillary action.


– Internal

In theory, concrete’s structure and characteristics can be improved with the right mix and process. But it’s not easy. Standard cement contains a lot of filler. Making it challenging to tackle water leakage from the inside.


The key to better water resistance is addressing external factors. This means improving concrete resistance to damage. Plus, it increases density, reducing original cracks and ensuring it stays stable after hardening.


Concrete is non-uniform and porous, having construction and structural voids. Construction voids happen during pouring if not compacted well. The structural holes form during hardening, related to the water-to-cement ratio.

How do you make super high strength concrete?

Making super high-strength concrete involves a few key steps:


1. Premium Ingredients. Start with quality materials, like high-grade cement and selected aggregates.


2. Low Water Use. Keep the water-cement ratio low. It is usually below 0.25 to boost strength.


3. Special Additives. Use WOTAIchem construction additives like superplasticizers to enhance workability without compromising strength.


4. Extra Materials. Incorporate silica fume and fly ash to improve durability and reduce permeability.


5. Good Mixing. Ensure a thorough mix using high-powered mixers.


6. Proper Curing. Follow strict curing methods, like steam or high-pressure, to maximize strength.


7. Testing and Quality Control. Regularly check the concrete’s properties to meet the desired high-strength standards.
