What is geothermal backfill?

After geothermal water is laid, a layer shall be backfilled. The purpose of backfilling is to store heat and protect the pipeline in the floor heating system.

Some suitable materials are selected for floor heating backfill, and a layer of heat storage layer is filled in the floor heating layer, which can not only effectively protect the floor heating pipeline, but also keep warm to prevent excessive heat loss, thus providing heating for a long time.

Although the backfill soil of floor heating can prolong the service life of floor heating to a certain extent, it needs to be constructed correctly. As far as the materials of floor heating backfill are concerned, concrete is generally used for floor heating backfill, which means cement, sand and green beans are needed.

Extended data:

After the local foundation before warm backfill is installed according to the construction specifications, the construction base can be cleaned, and the construction base must be guaranteed to be free of sundries and dirt, and the concrete can be mixed only after cleaning.

After the concrete is paved, it needs to be cured in time, and it needs to be watered sooner or later, but no one can step on the floor heating backfill layer within 24 hours.

Do not drill or punch holes in the area where floor heating is laid, so as not to damage the floor heating pipeline. After the backfill layer of floor heating is dried, the construction of the next procedure can be carried out, and the drying time shall not be less than 48 hours.
