What are the causes of floor have been surface moisture content is too high

What are the causes of floor have been surface moisture content is too high? Now requires most of the building's floor paint systems need to be waterproof layer ( DPM) 。 The waterproof layer is generally through the ground base on/off the cladding polyethylene waterproofing material or asphalt waterproof material to form. Wet through congress cause fluid static pressure, such as groundwater ooze a base level, etc. General floor waterproof membrane or sink or drainage pipe system is not the case. But we also should pay attention to, if only have drainage pipeline, but without the waterproof layer of floor system, we need to base moisture test, and combined with other related factors are considered, such as underground water level, etc. Serious fluid static pressure and even lead to ground surface failure.

many resin floor system cannot be used in the base surface of high water content, therefore, if we use the floor paint materials to make bottom coating before the completion of the phenomenon be affected with damp be affected with damp, and is likely to lead to the entire floor system in the painting is finished, fastness to big affected, leading to floor surface bubbles, delamination, and even failure.

in general, only in the following several reasons, will lead to the base surface moisture content is too high:

1, is not equipped with modern architecture of the waterproof layer

some building types, such as warehouse and logistics center, itself is not the implementation of the floor system, so there is no waterproof layer. But once converted into other functions of the building, then the problem of high water content will be revealed.

2, base completion time is short, or did not dry

a lot of practice has proved that after the completion of the base level to allow it to dry naturally the best results, after the completion of the otherwise is likely to lead to floor system problems. But modern construction speed, often can't spend a lot of time, so use resin material for coating way more and more popular.

3, waterproof layer failure

the waterproof layer failure situations may arise, although there are many kinds of, the cause of the failure is because the painting is not correct, but usually during the waterproof layer is damaged or coating, such as reinforcing bar pierced, etc.
