Frequently asked questions about PERMAGEL

Frequently asked questions about PERMAGEL

What kind of walls can I seal with PERMAGEL?

All older buildings with bricks, natural stones, half-timber, sand-lime bricks, lightweight concrete blocks, hollow stones, double-leaf cavity walls with facework can be sealed with PERMAGEL. Also newer types of hollow stones (e.g. Poroton hollow bricks, sand-lime) can be very well sealed. This is also the case with natural stone and half-timbered buildings, as well as expansion and construction joints of concrete buildings.

What is not possible?

Large size blocks (e.g. YTONG stones) or concrete itself.
The reason: PERMAGEL is no hydrophobizing agent, it does not seal the capillaries inside the stone like an impregnation does. PERMAGEL seals all gaps, cracks, cavities in the wall and thus avoids the transport of water from the foundation as well as the traverse moisture penetration which results from insufficient waterproofing.

How does PERMAGEL act in damp walls?

Even small amounts of PERMAGEL in the wall transform the water inside the wall into a proofing gel and blocks oncoming water. PERMAGEL finds the water by itself, fills all invisible water accumulations in the wall. 100 ml of PERMAGEL transform 10 liters of water into a proofing gel.

How do I proceed to seal my wall?

First you need to find out what type of stone you have (full bricks, hollow stones, small or large-sized formats), how thick your wall is, and to what height the moisture has already risen. Does your building (year of construction?) have a continuous bottom plate or a strip foundation (see construction plans)? When you have all the information, please concact us and we will discuss together how to proceed. Because every building was built very differently, the individual type of construction, the materials, etc. need to be considered. That’s what we’re here for, we will sort this out together, just give us a call or send us an email. The advice is free of course.

Can I do the sealing myself?

Yes, this is no problem. You just need one of our sets, an 18 x 400 mm drill bit and a drill, that’s all. If the plaster is already highly damaged, it must go. After that, expose the gaps, mark the drill holes, depending on the type of stone drill angularly downwards or horizontally into the gaps, drive the plastic packers in (included in the set), inject the gel, cut off the packers flush with the wall, spackle the spot, done.

Where can I order the required parts?

We sort out together how much material you need and after that you can order through us in our shop. Or you search for “Permagel” on ebay, all our products are listed there, too. You can pay via PayPal in both cases and in our shop also in advance via bank transfer.

Is there a warranty for PERMAGEL?

Of course we warrant the effectiveness for 15 years. Understandably we cannot provide any warrany for the work you do or for any misapplication.

How long does a PERMAGEL sealing last?

For life, if you do it right. Our partner Fraunhofer Institute can prove the effectiveness by the current state of scientific knowledge at least 15 years, but at least 50 years can be expected. PERMAGEL stays active and responsive the whole time, and it will still stop water coming through new cracks or settlings in the wall after 15 years.

How much PERMAGEL do I need?

The required amount of PERMAGEL needed depend on the wall thickness, the type of stone, full bricks or hollow stones, the number of imperfections in the wall and the design of the building. Here are some average values:

Wall thickness Required amount
Distance between drill holes for
horizontal barriers
Distance between drill holes for
wall injections
24 – 30 cm 120 – 150 ml / drill hole ca. 14 cm 20 – 25 cm
36,5 cm 200 – 250 ml / drill hole ca. 15 cm 20 – 25 cm
36 – 60 cm 250 – 500 ml / drill hole ca. 15 cm 20 – 25 cm
60 – 120 cm 500 – 800 ml / drill hole ca. 15 cm 20 cm

Hollow stones: ca. 150 ml more per drill hole which is equivalent to ca. 2.5 cartridges at 7 drill holes per meter
In general: ca. 6 – 7 drill holes / meter horizontal barrier and ca. 20 drill holes / m² wall injection
Keep in mind: 1 liter of PERMAGEL can transform 150 liters of water inside the wall into a proofing agent. It grouts itself within the masonry, finds every hollow spot, crack or tear.

Ho do I seal a wall with PERMAGEL?

Sealing a wall with PERMAGEL – quick and easy

Moist walls inside your house are not just ugly to look at but they smell bad and they are a risk to your health. Wet walls are quickly covered with mold which is hard to get rid of. So you should take preventive measures against wet walls so that mold has no chance. With PERMAGEL you can seal moist masonry in a quick an reliable way.

Dry up moist walls in a reliable way

PERMAGEL turns water inside the wall into a sealing gel. This way you not only get your wall dry again but you also protect it against new water penetration. PERMAGEL can be used to seal old buildings built with anything from brick, half-timber or lightweight concrete. The procedure differs depending on the type of stones and the level of moisture.

We offer expert advice free of charge and without any obligation on how to successfully and sustainably seal your moist wall. With PERMAGEL you can seal the moist wall yourself. Moisture in the basement is not a big problem anymore. During a personal consultation free of charge we determine how much material you need to seal your wall sustainably. The application is super easy.

There is no need to wait after the injection is finished because PERMAGEL is active immediately and starts to seal your wall. You can order PERMAGEL in our shop any pay with PayPal or in advance via bank transfer. When using PERMAGEL correctly we guarantee the effectiveness for 15 years. Fraunhofer Institut proved that PERMAGEL can seal walls from moisture for up to 50 years. Our product can seal your wall after such a long period of time because it always remains active and responsive. So if you’re looking for a way to seal you walls reliably for a long time, you should opt for PERMAGEL.
