Global Pavimenti supplies and lays different types of floor joints, such as structural, expansion and fractionation joints.

The proper assembly of joints requires great ability.The preliminary preparation of the supports and the fire partitions explain the complexity of this type of work.Nevertheless, Global Pavimenti can carry out special mechanical and chemical fixing, if it is necessary, by using self-tapping screws and epoxy resins.Our company tests each joint to certify its quality, resistance and watertightness.To guarantee the joint seal, we carry out two tests that are described in short as follows:

Watertightness test

The test is carried out to check the joint’s watertightness because the joint is placed outdoors and it is subjected to the weather. A tray containing colored water is placed close to the joint to check infiltrations through the connection.

Gas-tightness test

The test is carried out to check the joint’s tightness as the joint is placed outdoors and it is subject to the weather. The test uses nitrogen. After cutting the sheath close to the joint, gas is released with a fixing valve and a sensor detects the joint tightness.

The removal of the joints in existing floors can be due to several reasons. Anyway, before replacing the damaged joints, the following assessments should be done.

First it is better to find the cause of the damage; therefore some information should be taken from the designer of the building where the work is going to be carried out.

After, we need to assess the level of building’s exposure to the weather and the operating loads the structure is usually subjected to.

After these assessments are taken, we can identify the new joint to be used so that it won’t have the same problems of the damaged one.

The replacement procedure involves cutting the floor close to the damaged joint, demolishing a part of the floor, preparing the place where the joint will be placed and forming a suitable supporting surface.
