When building a house, laying the dimpled sheet is an important step, without which the building can not go on. But even after construction, it can happen that the dimpled film becomes porous and must be renewed as part of renovation work. We will show you how to carry out this task professionally and what costs are incurred by the measures.

The dimpled sheet separates the soil from the foundation wall. One of the problems with the construction is that it comes through the contact of the building with the earth to a moisture transfer. The building is kept permanently moist at its base, which is detrimental to the building fabric. The groundwater increases the burden on the foundation wall, causing damage in the short to medium term, depending on the moisture level. The correct attachment of the dimpled foil is crucial for success. Only if the work is carried out professionally, the protection of the building is guaranteed.

What tasks does the dimpled sheet fulfill?>> The alignment of the dimpled film

The task of the dimpled sheet is to ensure the insulation against moisture in the area of ​​the cellar construction. You present the nubbin film from the outside. This raises the question of which direction the nubs should show. If you decide to direct the pimples to the ground, then you have to attach a fleece from the outside. Otherwise, there is a risk that the gap fills with sand. The fleece also promotes the drainage effect and supports the drainage of the water.

Tip: Some dimpled sheets already have an integrated fleece.

If, on the other hand, you direct the knobs to the structure, then no fleece is necessary. Below is a list of the advantages and disadvantages of both options:

Nubs point to the building:

• Nubs can not pollute
• The obstruction of the masonry is ensured

Nubs point to the ground:

• the mechanical protection increases
• is combined with drainage

Laying the dimpled foil

Step 1 - If there are still remains of the old dimpled sheets on the masonry, then you have to remove the foil remnants. Often, over time, the material becomes porous so it is no longer effective and needs to be renewed.

Step 2 - If dirt has accumulated on the wall, then you must remove it.

Step 3 - A bitumen coating protects the basement walls from water, which acts on the wall without much pressure. It is a waterproof protection, which is applied before laying the dimpled sheet.

Step 4 - Place the dimpled sheets so that they project about 10 centimeters over the paint. At the bottom, make sure that the dimpled foil is above the drainage tube. For fixing use nails, which are fastened over the nail edge in the wall.

Step 5 - Lay the tracks horizontally. You do not have to unwrap the film, but you can unwind and attach it directly from the roll. As a result, you work precisely and put the film optimally on the wall. The horizontal attachment is not absolutely necessary, it can also be a vertical attachment, but it is less common.

Step 6 - If you have misplaced the first lane, then you must make sure that the second lane is placed about 10 centimeters above the first lane. This is the only way to ensure a safe and complete effect.

Tip: there may be windows or other openings on the surface. Cut out the relevant spots so that the foil goes around the obstacles.

What costs do I have to expect ">

Which different possibilities of fixing the dimpled foil are possible ">

Tip: If you are laying the dimpled sheet over a corner, then you should fold the film in place before attaching it. This gives it the right shape and can be easily attached. It is important that you push the foil well into the corner so that no air builds up behind the foil.

How do I proceed in the area of ​​drainage piping?
The drainage pipe must be surrounded with at least 20 centimeters of seepage material. Among other things, slag granules or concrete gravel are suitable for this purpose.

Should I hire a specialist company for the work ">

• Transfer drainage tube output with 20 cm seepage material
• Apply bitumen paint
• Fix the dimpled sheet only on a cleaned underground
• Knobs may point towards the ground or toward the structure
• many dimpled sheets already have integrated fleece
• The dimpled sheet has to protrude about 10 centimeters above the painting
• Lanes must overlap
• Lay vertically or horizontally depending on the manufacturer's information
