LDPE closed-cell foamed polyethylene expansion joint cord with diameters of 6, 8, 10, 13, 15, 20, 25, 30, 40, 50, 60, 70 mm and round profile of nominal diameter

In construction projects, the most important thing is to use solutions that will last for many years. This is what expansion cords make possible. These seemingly insignificant elements are responsible for the stability and safety of the entire structure. Where and for what purpose are they used?


What is the expansion cord used for?

In construction, small gaps are left between two surfaces to counteract their deformation. Thanks to them, it is possible to prevent cracking and damage to structural elements. Thanks to expansion joints, each element of the floor or building carries all the loads independently, and this will make your investment last for many years even in difficult conditions.

A specialized cord is used to fill expansion joints in walls, floors and building structures, including the installation of facades, windows and doors. It is placed before the application of sealing compounds. It will work well for both concrete elements and ceramic floors.

The expansion cord is designed to protect the substrate from deformation due to heavy loads or changing temperatures. It also provides protection against moisture. Therefore, it is especially important for outdoor structures such as a balcony or terrace.

How to choose the right expansion joint cord?

Construction projects are most often undertaken with at least a dozen more years in mind. Therefore, during the work it is worth considering the most effective architectural solutions. One of them are expansion cords made of polyethylene foam. They are characterized by high flexibility, which is especially important in the case of heavy structural loads, and at the same time they are simple to install.

The key aspect to consider when filling expansion joints is the diameter of the cord. It should be about 20% larger than the width of the gap. In our offer you will find products for expansion joints with diameters of 6 mm, 8 mm and 15 mm.

The price of cords made of foamed polyethylene is adequate to the quality. They can easily cope both indoors and outdoors, while the closed cell structure effectively prevents the material from soaking.
