At present, most underground projects in my country use traditional materials as a waterproof layer. The waterproof material is paved on the base surface of the cushion, and then the protective layer is used to pour the concrete structure. Process:

The waterproof layer and structural concrete formed by this process cannot be bonded. The defect is that when the waterproof layer is damaged, the groundwater will occur between the waterproof layer and the structural layer.

In 2010, the Ministry of Housing and Urban -Rural Development issued the “10 New Technology in the Construction Industry”

Pre -shop anti -adhesive process is introduced from abroad to China’s water prevention industry

In recent years

The momentum is quite rapid, and it is gradually favored in waterproof construction

What is pre -shop anti -adhesive process?

Put the polymer waterproof coils from the level of the mucous membrane to the structure of the structure, and then pour the concrete structure to close the concrete and the coil film layer tightly. Waterproof process.

Waterproof coils wrap the structure concrete from bottom to top

The close combination of the two prevents the problem of channeling

Fundamentally improved the reliability of groundwater resistance

Advantages of pre -shop anti -adhesive waterproof technology:

The rise of pre -paving anti -adhesive process is not accidental. In addition to solving the problem of traditional craftsmanship, it also has other advantages, bringing many high -quality changes to waterproof engineering. Detailed construction plan:

Rain full waterproof: pre -pavement polymer self -adhesive film waterproof coil construction technology

1

Requirements to the grassroots

No base oil/grassroots treatment agent is required, just clean up, no obvious bumps, and can be constructed on humid base surfaces.

2

Short construction period, reduced later costs

The construction method is convenient. It only requires a process to achieve a first -level protection effect. It does not need to be a protective layer. The efficiency of work is several times, and the cost and manpower are reduced.

3

Materials are environmentally friendly, and construction is safe

Taking the pre -pavement polymer self -adhesive membrane waterproof coils as an example, the raw materials are green non -polluting and non -harmful substances; there is no need to use hot -melt and bright fire construction during construction, which improves the safety and guarantee of the construction personnel.

New type of waterproof material pre -paving anti -adhesive coil construction technology will be large -scale in underground waterproof projects in the future;
