Cementmix: application

What Cementmix does:

Cementmix makes every concrete and cement / grout waterproof, while maintaining vapour permeability. The reinforced rebar is permanently protected against water intrusion. There will be no water seeping down or up to the rebar, it will be fully protected with Cementmix.


How Cementmix works:

Cementmix makes the concrete / cement / mortar through and through waterproof.


How to use Cementmix:

Cementmix replaces the water in the mixing process. So it goes directly into the bucket or cement mixer while making concrete / cement and mortar.


Use how much Cementmix:

Whatever water you would need to get the job done, you will need the same amount of Cementmix.
For example: 5 liters Cementmix represents 5 liters of water in the mixing process.

The difference between Cementmix, Oppercon and Permacon:

Cementmix replaces water and makes all kinds of cement, concrete, self-leveling mortar etc., through-and-through water- and liquid proof. This applies to both the surface, as for the underlying layers. Any finish like paint, cement or any other kind, is not possible. The treatment is permanent.

Oppercon is a surface treatment repellent agent for concrete, stone and stony materials.
Without leaving any visible trace of its presence, it will, unlike Permacon, make the surface of these materials waterproof, water repellent and UV-resistant. Because of its repellent properties, it means that a finish, like paint, cement or any kind of finish is not possible. The Oppercon treatment should be repeated after 15 years.

Permacon can be applied to any cementitious surface (concrete, stucco, concrete bricks, stone bricks, marble, gypsum or porous natural stone etc.). Its simplicity as for the application techniques, makes it most convenient for the treatment of walls, floors, ceilings and any structure made with these materials, in any form and size.

Permacon is very suitable under hydrostatic pressure for concrete ending up underneath the soil, like basements, foundations, sewage pipes, tunnels or with floor heating etc. after you’ve applied Permacon. Unlike Oppercon, which is a repellent agent, it’s possible to add a finish paint, cement or any kind of finish you wish. Guaranteeing a perfect, durable and waterproof surface.
