Waterproof material "Selcoat"

Protect concrete from salt damage and freeze damage! Waterproofing material that densifies concrete structures.

"Selcoat" is a waterproofing material composed of inorganic substances that penetrates the interior of concrete, chemically bonding with the main component of cement to close capillaries. By closing the capillaries, it forms a waterproof layer that prevents water penetration into the concrete. It is effective not only for waterproofing concrete tanks but also against salt damage and freeze damage. Additionally, it can be applied in a wet state without the need for thick application like waterproof mortar, providing waterproofing effectiveness at a thickness of 1.2 to 1.5 mm. 【Features】 - Closes the capillaries of the concrete structure to form a waterproof layer and prevent deterioration. - Safe for work inside tanks due to its inorganic nature. - Non-toxic and also contributes to the corrosion protection of rebar. - Can be applied in a wet state. - Available in powder form and can be mixed with water for application. *For more details, please refer to the PDF document or feel free to contact us.

Causes of construction material troubles

By suppressing water absorption, aesthetic appeal and degradation protection can be maintained!

The "LIQUID GUARD" that we handle is a penetrating water-repellent agent that protects building materials from various troubles. Most building materials are water-absorbent. If there is no water absorption rate, moisture uptake, efflorescence, surface stains, and rust will not occur. Due to their water-absorbent nature, building materials can become contaminated. By suppressing water absorption, aesthetic appeal and deterioration protection can be maintained. 【Features of LIQUID GUARD】 ■ Does not change the appearance of the material ■ High durability protection ■ Efflorescence prevention effect *For more details, please download the PDF or feel free to contact us.
