Perimeter drainage - Prices and Guide

Are you in a situation where it has become necessary to put a perimeter drain around your house? Then you might also be wondering how much it will cost you.

Here you can read more about perimeter drains, price examples, how to get perimeter drains installed as cheaply as possible and much more.

Perimeter drainage price

It is not cheap to establish a perimeter drain. A perimeter drain consists of drainage pipes, treatment wells and a pump well. They are connected to the sewer network and are a big job, which must therefore only be carried out by an authorized sewer master.

Is a perimeter drain necessary?

Whether you should have established a perimeter drain can be a big decision, as it often costs DKK 150.000 or more. It is therefore important that you get excluded other cheap solutions on a damp basement, and here you need the help of an expert.

The construction of a perimeter drain must be carried out by an authorized sewer master, and he can check both inside and outside why you have a damp basement.

In some cases, a damp basement is simply due to condensation if you use the basement to dry clothes in or if the basement is very cold. This can often be done with better ventilation, and you can e.g. try installing valves, putting heat on or a point extractor.

A damp basement can also be due to the terrain sloping towards the house instead of away from the house. It may also be that roof wells or downspouts have broken, or need to be cleaned.

Your basement walls can also be leaky, and they may need to be insulated. It is best to insulate them from the outside, and many choose to have the basement walls insulated at the same time as they have established perimeter drains.

Preliminary examination of sewer master

Since establishing a perimeter drain is a big investment, it is a good idea to get several sewer masters to assess whether you need a perimeter drain and how it is best and cheaply established.

The cost of establishing a perimeter drain will depend on many things:

• How far to dig down
• How many meters of perimeter drain to be laid
• How and with what materials should the basement walls be insulated
• Whether the foundation must be concreted so that one can dig safely far enough down
• The size of the pump well

It is therefore a good idea to contact more than one Horsens sewer master to see if there is more than one solution when the perimeter drain is to be established. Here, the platform 3byggetilbud.dk can clearly be recommended, as the sewer master thereby knows that he is not the only one who submits offers, which of course is reflected in the price.

Perimeter drainage are established

If you need to install perimeter drains, it is of course nice to know what the establishment of a perimeter drain may cost. But that's hard to say as it depends on so many variables.

Scope drain prices start at a minimum of DKK 3,500 per. running meters, and you can measure how many meters there are around your house.

A detached house with a ground area of ​​150 m2 will typically need a perimeter drain of approx. 50 m. The price of a perimeter drain will thus be a minimum of DKK 175,000 if you need a perimeter drain around the entire house.

DKK 3,500 is, however, a very low price for a perimeter drain, and includes excavation to a depth of 1.5 meters. At the vast majority of houses, you have to dig much further down, and you can expect to pay DKK 10,000 per. running meter.

This makes the price of a perimeter drain easy up to DKK 500,000 and that is a lot of money for most people. If you take out a 30-year loan in the house, it will be approx. DKK 2,000 extra per month.

Some houses can just have a perimeter drain laid around one of the sides of the house, and then it will of course be cheaper. But only a sewer master can assess whether it is a good idea to settle for one side.
