The waterproof warranty is five years.

The warranty period of waterproofing engineering is at least five years, and the relevant regulations indicate that under normal use conditions, the minimum warranty period for roofing waterproofing projects is five years, and the minimum period for leakage prevention in toilets, exterior walls and other areas with relevant waterproof requirements is also five years.

Attention should be paid to waterproof construction:

1. Main basic treatment. The first step in waterproof construction is to deal with the regional base with waterproof requirements, including removing the original decorative materials, dust, floating soil, cement, etc., all of which must be cleaned up.

2. Pay attention to special parts. It is best to lay a layer of glass cloth on it, which can enhance the adhesion of waterproof coating and improve the waterproof effect.

3. The closed water test cannot be less. After the waterproof construction, the closed water test must be carried out, it can check the quality of the waterproof construction, the waterproof project is completed and the sewer is sealed, and then the area of the construction waterproof layer is filled with water, wait for 24 hours, if the water level does not change significantly, it is qualified.

The defect liability period arises because of the project warranty. If the waterproof warranty period is five years, it is very unfavorable to the contractor, so the defect liability period is established, and the defect liability period shall not exceed 24 months, and all payments will be paid at the end of the liability period, but the warranty period will continue to be performed. The specific differences between the two are as follows:

1. The starting date of the warranty period shall be calculated from the date when the owner's engineer issues the project completion certificate;

2. The defect liability period is calculated from the date when the project passes the completion (delivery) acceptance; If the project cannot be completed (delivered) and accepted within the prescribed time limit due to reasons attributable to the employer, the project will automatically enter the defect liability period 90 days after the contractor submits the completion (delivery) acceptance report.
