What is the best remedy for water seepage on the wall of a new house?

The first category: accurate installation of pipeline leakage is the key.

The water pipe connection in the room is not connected properly. How to deal with water pipe leakage? This is what many people really need to know.

Cause: The pipeline is not installed correctly.

Pipeline installation and fixation are not in place, resulting in looseness; There is an error in the position of the reserved port of the pipeline, and the concrete pouring is not in place; Did not do a good job of leakage prevention.

Repair method: cut the pipeline to make it waterproof.

Digging a hole in the pipeline, and brushing cement oil at the bottom of the mold; Cast high-grade concrete, and make a layer of waterproof coating around the dry nozzle. Do a water seepage test after 24 hours, and the wall can be restored without any problem.

Prevention method: fix the pipeline.

In order to avoid future troubles. Remember to install, fix the pipeline and cast concrete according to the specifications during construction. Do every step carefully, so as to play a preventive role.

The second category: the waterproof layer of the roof should be redone.

Waterproof layer is a material layer to prevent rainwater from entering the roof, groundwater from infiltrating into walls, basements and underground structures, and indoor water from infiltrating into floors and walls.

Cause: The waterproof layer is damaged.

Man-made construction damage causes water leakage in the waterproof layer; Damage caused by pipeline installation and damage caused by protective layer or waterproof layer construction; The quality problem of waterproof material will also lead to the destruction of waterproof layer.

Repair method: shovel and redo waterproofing.

Find the leakage point, shovel off the protective layer of the wall and ground, and waterproof again. After the redo work is completed, the permeability test is done within 24 hours, and there is no problem in concrete repair.

Prevention and control methods: do a good job of water seepage inspection.

After the waterproof layer is completed, check the water seepage immediately, and then do the next decoration if there is no problem. At the same time, it should be noted that in the construction process, the waterproof layer should be prevented from being destroyed.

The third type: the walls and floors are black spots, and immediately look for leakage points.

It is found that the wall is wet with black spots, or there is water leakage at the top and wall. In some homes, the wall is wet or even moldy and hairy every winter, so we must find the water leakage point as soon as possible.

Cause: Not fully compacted.

The construction personnel did not construct according to the construction requirements and specifications, and the concrete was not fully compacted when pouring the floor slab, resulting in quality problems such as empty drum, honeycomb and pits; Or there are quality problems in cement and concrete itself.

Repair method: shovel and redo.

Once water leakage is found, find the water leakage point as soon as possible. After finding the leakage point, shovel off the protective layer of the leakage point on the wall or ground. Then according to the specification maintenance, waterproof, and then restore.

Prevention method: choose appropriate concrete.

During construction, choose appropriate concrete pouring, construct according to requirements and specifications, and fully tamp and pour. After the construction is completed, the post-curing shall be carried out according to the construction design and specifications to ensure that the concrete does not crack.

Fourth: prevent cracks from leaking and do a good job of maintenance.

Crack leakage is one of the highest problems, and maintenance is particularly troublesome. Water leakage in the upper and lower floors often leads to disputes and contradictions among owners, tenants and property companies.

Cause: The concrete temperature is not controlled.

When pouring concrete, the temperature control is not good, the maintenance is not in place, the ratio and structure of steel bars, and the roof load is too heavy; The construction of settlement joint, expansion joint and post-pouring belt is not standardized, and it is not done well according to the design and specification.

Repair method: clean the concrete.

First, clean up the concrete with bad joints, and then repair it with higher grade concrete according to the requirements of construction specifications. It is best to use high-pressure grouting to repair cracks.

Prevention method: pouring according to the specification.

Concrete must be poured, vibrated and maintained according to the design and specifications. The reinforcement ratio of steel bars must be constructed according to the design requirements.

Water seepage on the wall of the house should be solved as far as possible in the side leakage link before decoration, so that manpower, material resources, financial resources and energy will not be wasted.
