Permacon Concrete Waterproofing: Specifications and features

Permacon Waterpoofing makes concrete permanently waterproof. It hardens the surface, prevents dust forming, plus you could coat it with a finish of choice (this aspect is merely for aesthetic reasons).

Permacon really goes into the building material and you can paint over it, if you want a concrete sealer, which makes a protective layer on the material, you can use Oppercon.

Save money and time with Permacon Waterproofing!

  • Saves renovation costs: protects against algae, moss and fungal.
  • Protects building materials: hardens the surface and makes it 100% waterproof
  • Prevents structural damage: prevents rising damp, extends the life of concrete


  • Promotes density, strengthens and hardens the surface.
  • Helps concrete to harden evenly during curing and prevents cracks.

Permacon: application

What Permacon does:

Permacon makes concrete waterproof, unmovable, impenetrable and it stops rising moisture/damp while maintaining the vapor-permeability. This is an important requirement for good water management inside the home!

Suggestion: For aesthetic reasons, you can finish the surface with a water-repellent coating such as Oppercon, although this is not necessary for the liquid-proof of the concrete.

How Permacon works:

Permacon ensures that the entire surface area of the concrete (about I inch) from the surface is saturated with the gel. This gel fills the entire capillary pore system. It stabilizes all free particles including water and once the water has evaporated, a crystallized core remains that is immobile and has become a permanent part of the concrete and is impervious to liquid. As a result Permacon strengthens the pores of the concrete and stops rising damp and concrete rot permanently.

Thus, Permacon therefore stops the process of water migration in concrete, whereby all matter is fixed in place and made immobile. This also applies to any harmful substances present in the concrete itself, such as chlorides, sulphates and other contaminants of various kinds. The crystals cannot diffuse or otherwise move through the concrete / cement. Due to the complete integration of the crystal-pore-filling in the concrete / cement itself, will high hydrostatic pressure be held back and won’t be able to bring about any movement of these materials and all this with the vapour-permeability maintained.

Now is a saturated surface created with complete protection against liquids. These are the important characteristics that contribute to the unique formula called Permacon, which gives concrete / cement a permanent protection and stops rising damp and concrete rot.

How to use Permacon:

Apply the first layer of Permacon with a low pressure sprayer. Depending on how wet the concrete is, you should wait between 4-18 hours before applying the second application.

Before you apply; the surface needs to be completely stripped of organic debris and or pore-sealing layers like paint or other obstructive material which could stop Permacon from penetrating the surface.

Note: On a real warm day the concrete in open air will be hot, so on these days we recommend you apply a spray of tap water before you apply Permacon. When you done this, wait until the surface is yet again  dry. You can see this easily enough by just looking at it 😉 Then start with the first Permacon application.

  • Permacon application instruction

    Application instructions:

    • Preparation:

      The surface needs to be clear of any organic and pore-sealing materials like paint or other obstructive  materials. The surface should also be free of cracks bigger then hairline cracks and holes. These need to be fix before you continue. Permacon should NOT be applied on a wet surface.

    • How to apply:

      Spray Permacon with a low-pressure nozzle equally across the surface without creating puddles. Permacon will penetrate the surface really quick (the surface tension of Permacon is practically zero), for that reason you might think that “have I sprayed there yet” because it will dry really quick, so once you been at one spot, no need to go back.

    • The second spray:

      Note: The moisture content of newly poured concrete -when it has sufficient ripeness but hasn’t hardened completely out yet- will be relatively high. In that case the second spraying should be applied 24-48 hours after the first spray in exactly the same manner. With existing (old) concrete the second spray can be applied 8-12 hours after the first application. For ponds, wait at least 7 days before filling with water

    • At high temperatures:

      In case the concrete is very dry, like on a windy or warm day we recommend you spray the concrete surface with a layer of tap water, before you apply, in between and afterwards. The second application with Permacon can be done once the surface dried up yet again. Permacon is water based and nontoxic and none flammable product. But we do recommend you wear gloves and in case your above shoulder height, we recommend wearing goggles as well.

    • Coverage:

      Two applications with Permacon should be sufficient. With 1 litre you’ll cover an average of 88 ft2. Applying Permacon twice, brings the average to 1 litre per 44 ft2.

    • Rain:

      If you can avoid rain it would be better of course, but It’s not an real problem when it rains after the application has been done; Permacon disperses quickly in the surface and will therefore not be washed away. The actual reaction within the capillary-pore-system will continue. Permacon has hardly any surface tension and it will disappear into the concrete surface very quickly. The property of very low surface tension, to be able to  penetrate the concrete very quickly on its own power, is one of its special characteristics.

    If something is not clear or you have a question, please don’t hesitate to contact us, we’ll be happy to help.

Use how much Permacon:

1 litre Permacon is sufficient for an average of 44 ft2.

The difference between Permacon, Oppercon and Cementmix:


Permacon can be applied to any cementitious surface (concrete, stucco, concrete bricks, stone bricks, 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.


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.


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.

    Wij hebben het recent in Spanje verwerkt. Na een stevige regenbui was het resultaat zichtbaar. Dus zeer tevreden.
    Kunnen jullie ook in Spanje leveren?
