Do you need to do whole house waterproofing before doing floor heating?

Installing floor heating is sure to do waterproofing, the purpose is to prevent water pipe leakage from harming the downstairs, if there is a condition to do two times waterproofing, floor heating above the layer below, if there is no condition, then do the upper layer, that is to say, after the floor heating is laid, install waterproof to do a closed water test.

First, after the installation of floor heating, it is necessary to do a pressure test, and each room has a pressure gauge.

After the verification is completed, the backfill construction will be arranged. That is to say, if there is no water leakage and pressure relief before this step, most of the water leakage phenomenon in the later stage is caused by human factors.

Second, if the floor heating is laid on the top is not waterproofed, the domestic water pipe in the room is faulty or leaking, it is likely to affect the downstairs, the floor heating is waterproof, there is no possibility of leakage of the domestic water pipe, in case of water leakage, it is easy to find out the cause of the water leakage, so as to avoid the phenomenon of ripping between the owners.

There is no need to do the whole house waterproof before doing floor heating, the reason is very simple, because the service life of the floor heating pipe itself is very long, and the floor heating pipe is backfilled with concrete after laying the floor heating pipe, which is to protect the floor heating pipe, so that the life of the floor heating pipe can reach 70 years, which is also the reason why the floor heating manufacturer dares to guarantee 50 years, its life is the same as the life of the house, and there is no need to do waterproofing.

Precautions: Before backfilling concrete, the water must be pressed to prevent water leakage due to damage to the floor heating pipe during laying; Then it is to avoid nailing on the ground to prevent water leakage caused by penetrating the floor heating pipes; In the heating, it should be cleaned regularly to prevent the inner wall from absorbing too much scale or impurities, which will affect the heating effect.

The floor heating in the bathroom should be waterproof, and it is necessary to do two waterproofs, as follows:

1. The first waterproof: whether the bathroom leaks or not, a traditional waterproof must be done before the floor heating is laid, and the water injection test must be carried out for more than 48 hours without leakage or seepage before the construction can be carried out, because when taking a bath in the bathroom in the future, there will be a large amount of water flowing on the ground, and if the waterproof is not done, it will not be good if it penetrates downstairs;

2. The second waterproofing: after the floor heating is paved, make a layer of waterproof on the floor heating, so as to prevent the ground water from penetrating into the floor heating protective layer, which can improve the thermal effect of the floor heating. Don't wait until the floor heating is paved and the tiles are pasted and you find a water leak, which will make the repair more costly.

The bathroom is equipped with underfloor heating, which also needs to be waterproof. Nowadays, the general bathroom has caissons, so in general, it needs to be waterproofed three times.

The first time is that a waterproof is required before backfilling, and this layer also needs to be tested for closed water.

Secondly, the second layer is the ground backfill, and a layer of waterproofing needs to be done after leveling.

The last layer is to do waterproofing again after installing floor heating, and this layer also needs to do a closed water test.

But this is mainly for you to install plumbing, if it is electric heating, then the layer after leveling can also be optional. The focus is on waterproofing the bathroom after installing floor heating, and it is recommended to use mortar waterproofing agent, so as to better withstand the high temperature of floor heating.

Of course, we have to do it, and we have to do two waterproofs. First, do a traditional waterproofing in the lower floor of the floor heating so as not to affect the users downstairs. Second, a layer of waterproofing is being made on top of the floor heating to prevent the ground water from leaking into the floor heating protective layer, so as to improve the thermal effect of the floor heating.

It is recommended to use BBN waterproof! **Suitable, and the quality is relatively good!

Regardless of whether the bathroom leaks or not, it must be waterproof before laying floor heating, and the water injection test is not leaking or seeping for more than 48 hours before the subsequent construction can be carried out.

Because the bathroom has to be bathed, a large amount of water flows on the ground, and if the waterproof is not done well, it will leak downstairs and cause serious damage to people. Therefore, it must be done well, and there is no problem after the water injection test before the construction can be continued. Otherwise, the floor heating is paved, the tiles are pasted, and the water leakage is found, and it will be very troublesome to repair, and the cost is much larger than the original budget.

Hello, I'm glad to answer for you, there is no clear rule that you must do waterproofing. The safety performance of floor heating is safer than other heating methods, because the coil buried in the ground is jointless, and the life of the floor heating coil is more than 50 years, that is to say, the life of floor heating is more than 50 years without human damage. The second is that the part of the floor heating with a joint is in the position of the water collector, and the position of the water collector is installed in the kitchen and bathroom in the room with floor drain.

After the installation of the floor heating system, the pressure test is carried out, and the pressure test is carried out until the backfill is completed. Therefore, it is said that Dixiang group heating is the safest heating system. Because water is used frequently in bathrooms and kitchens, it is necessary to make it waterproof.

It is best to do a water discharge before doing underfloor heating, and another water discharge after the backfill after the underfloor heating construction is completed. Other rooms can be left without waterproofing.

OK. The two waterproofing before and after floor heating are actually different. The waterproofing layer that is done before the floor heating is done is to prevent the leakage of the floor heating water pipe from seeping into the downstairs neighbors, and the waterproof layer is made after the floor heating is laid, so that the water pipe of the family will not leak into the floor heating and affect the water pipe of the floor heating.

In particular, some families will install floor heating in the kitchen and bathroom, balcony, if these spaces have to do floor heating, it is necessary to do two layers of waterproofing, if it is the living room, the bedroom and other places that do not use water, some people will choose to do only one layer of waterproofing. Only do the upper waterproofing layer after the installation of floor heating, but not the lower waterproofing layer after the installation of floor heating.

OK. The order from bottom to top is as follows: waterproofing - underfloor heating insulation board --- underfloor heating pipe--- aluminum foil mulch film - protective layer - waterproofing - backfilling cement --- floor or floor tiles.

Now it is generally required to do two times of waterproofing, and after the floor heating is laid, do waterproofing again on its protective layer, in fact, this waterproofing is also equal to doing it in vain, because the existing waterproof materials can not withstand the test of high temperature for a long time, the cement protective layer will eventually crack, and the waterproof layer will fail sooner or later.

Therefore, it is the key to do a good job in the waterproofing of the original ground under the floor heating insulation layer and the waterproofing of the threshold part.

Yes, the landlord floor heating is not done.

The order from bottom to top is as follows: waterproofing - underfloor heating insulation panels--- underfloor heating pipes--- aluminum foil mulch--- backfilling cement --- floors or floor tiles.

It is recommended to do the following, and there is too much uncertainty in doing it above.

Installing floor heating is to be waterproof, if the floor heating leaks, it will cause great losses downstairs, and these losses are borne by the upstairs. Unlike toilets, if the waterproofing is not done well, the loss is not particularly large, but the large floor heating coverage area may damage some of the most valuable property, so it is quite necessary to do waterproofing.

What to pay attention to when installing underfloor heating.

1. The floor heating pipe laid under the ground is only about 3-4cm away from the floor surface, and it is easy to hurt the floor heating pipe by smashing and knocking on the ground, so it is strictly forbidden to smash and impact the ground where the floor heating pipe is laid, and it is strictly forbidden to wedge sharp objects such as nails on the ground to avoid damaging the ground pipe. Especially in the process of house decoration, workers who should avoid cutting tiles should be afraid to cut and damage the floor heating pipes.

2. When placing scaffolding and other tools on the floor heating system, protective measures such as laying wooden boards to increase the stressed area must be taken to avoid damage to the floor heating system.

3. When the downstairs user of the floor heating user really needs to drill holes on the roof, it is necessary to pay attention to the drilling depth can not exceed the thickness of the floor structure to prevent damage to the upper floor heating pipe.

4. It is strictly forbidden to place a high-temperature heat source near the water collector and on the ground where the floor heating pipe is laid to prevent damage to the pipeline system.

5. When there is no heating in winter, attention should be paid to protection to prevent the cracking of the water separator parts and the freezing of the water in the heating pipe from blocking the pipe.

What to pay attention to in geothermal construction.

1. Pay attention to geothermal materials.

Geothermal energy belongs to the concealed engineering, the geothermal material is not selected, if there is a quality problem or a short service life, it is very affecting the use, and it will cause a very large loss, so the geothermal material should be tested before construction, and the surface of the high-quality floor heating pipe is smooth and not concave, there are no bubbles and obvious color difference, and the degree of softness and hardness is moderate.

2. Pay attention to field measurements.

Before geothermal construction, it is necessary to find a professional installation company for on-site measurement, because not every home and any functional area is suitable for installing floor heating, if it is installed in an unsuitable place, it is easy to have problems, and usually this kind of place needs a more reasonable design scheme.

3. Pay attention to the coil.

Geothermal must be strictly cautious in the construction, and the coil should pay attention to the distribution of the interval combustion void, and the bend can not be folded, so as to ensure the uniformity and stability of heat dissipation, and the air tightness of the system should be checked at any time during the construction, and the water injection pressure inspection can not be ignored.
