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. Also modern hollow bricks (e.g. Poroton hollow brick or sand-lime brick) can easily be sealed. This is also true for natural stone masonry, timber frame constructions, etc. as well as expansion and construction joints of concrete buildings.

What is not possible?

Large-sized blocks (e.g. YTONG) or concrete.
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?

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 1 liter 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 of
Distance FOR
Damp Proof Course
Distance FOR
Wall Injections
24 - 30 cm 120 - 150 ml / drilling ca. 14 cm 20 - 25 cm
36.5 cm 200 - 250 ml / drilling ca. 15 cm 20 - 25 cm
36 - 60 cm 250 - 500 ml / drilling ca. 15 cm 20 - 25 cm
60 - 120 cm 500 - 800 ml / drilling ca. 15 cm 20 cm

Hollow stones: add ca. 150 ml per drill hole, which means ca. 2.5 cartridges when drilling 7 holes per meter of wall
In general: ca. 6 - 7 drilling / running meter of DPC and ca. 20 drilling / m² wall injection
Please consider: 1 liter of PERMAGEL can transform 150 liters of water inside the wall into a proofing gel. It grouts itself inside the wall and thus finds all cavities and cracks.

How do I seal a wall with PERMAGEL?

Seal a wall with PERMAGEL - fast and easy

Damp walls in your house don't only look ugly, they also smell and pose a health risk. Mold appears quickly and is hard to get rid of. This is why you should do everything to prevent damp walls so mold has no chance at all. With PERMAGEL you can seal damp walls the fast and reliable way. 

Seal damp walls reliably

PERMAGEL turns water into a sealant. This way you don't only get a dry wall again, you also protect it from newly entering water. All older buildings with brick, half-timber oder even lightweight concrete block walls can be treated with PERMAGEL. The course of action depends on the degree of dampness and the type of stone.

We gladly provide you with free of charge advise how to seal your damp wall successfully and sustainably. With PERMAGEL you can easily seal the affected wall yourself. Dampness in the basement is no longer a problem. During a counseling session we explain your demand and what material you need to seal your wall sustainably. The application is super easy. 

Bringing PERMAGEL into the damp wall is easy and requires only little craftsmanship. There is no need to wait after the application, PERMAGEL is active immediately and directly starts to seal your wall. You can order PERMAGEL in our shop and comfortably pay via PayPal or prepayment. If applied correctly we guarantee an effectiveness of 15 years. The Fraunhofer Institute proved that PERMAGEL can even protect walls from dampness for more than 50 years. Even after such a long time our product can seal your wall by always staying active and responsive. If you are looking the seal your walls in the long run and reliably, PERMAGEL is the right choice.
