I would like to ask whether to pour concrete directly on the pipe after the floor heating pipe is laid or to pour it after laying another layer of something on the pipe?

It is better to lay soybean stone concrete or mortar on the underfloor heating pipe, the cement is silicate cement, and the sand is river sand; it is better not to pour the concrete or cement directly on the underfloor heating pipe but on the pre-prepared wooden board.

In order to avoid cracking of the backfill layer, generally 1cm above the pipe laying wire mesh mesh size should basically cover the dense area of the heating pipe.

Pouring conditions

1, pouring concrete layer section of the template, reinforcing steel, top buried pieces and pipelines, etc., all installed, checked in line with the design requirements, and run through the hidden, pre-check procedures.

2, pouring concrete with the frame and the horse road has been supported and built, and after checking qualified.

3. Cement, sand, stone and additives have been checked to meet the requirements of relevant standards, and the laboratory has issued a concrete proportion notice.

4, weighing scales (or automatic loading system) by checking the approved measurement is accurate, vibrator (stick) by testing the test run qualified.

5, the foreman according to the construction program for the operation team has been comprehensive construction technology training, concrete pouring application has been approved.
