Matters needing attention in closed water test

Closed water test is an important part of waterproof project acceptance. The following are matters needing attention in the closed water experiment.

The same waterproof material is dry.

The closed water test should be carried out for a period of time after waterproofing, and it is necessary to wait for the waterproof material to completely dry.

* * * Participate in the acceptance.

The closed water experiment needs the participation of the owner, the property department and the neighbors downstairs to check whether there is water leakage. If there is no water leakage, they will sign a contract together to show that they are qualified.

Blocking pipes and floor drains

The pipeline and floor drain of closed water laboratory should be blocked and kept watertight, otherwise the experimental results will be affected.

The door should also be blocked.

When the toilet and kitchen are closed, the door should also be blocked, and a dam should be built with putty powder or cement to make the water level reach the corresponding height, so that the water will not run from the door.

Reduce the impact of water

When discharging water, put a cover or basin at the impact of water flow to reduce the impact of water flow on the waterproof layer, make the experimental results more accurate and reduce the damage to the waterproof layer.

Leave waterproof paint bags and buckets.

Remember to leave those waterproof paint bags, buckets and lids when decorating, which can be used for closed water test. Bags are used to hold sand to block sewer pipes, and buckets and lids are used to reduce the impact of water flow on waterproof layers.
