Anti-buckling Mesh

What is the buckling of a floor slab? How can we solve it with a mesh? Let's discover it together!

Hello everyone, we are from Fenceshop, the e-commerce of Rete Plastic, and today we are talking about the buckling of floor slabs and how a mesh can solve this problem.

What is buckling?

Buckling is the detachment, the breakage of a portion of the floor slab, particularly of the hollow bricks that fall and cause problems. This phenomenon occurs primarily in constructions built between the '50s and '70s and presents a significant problem today.

Composition of the floor slab

A floor slab is composed of main pillars and beams that form a parallelepiped structure. Within this structure, there are joists connecting the various elements. Hollow bricks are perforated elements similar to bricks that fill the spaces between the joists and are embedded in a concrete cast, creating the floor slab.

Why does buckling occur?

Buckling is caused by the breakage of the hollow bricks, which break due to dilations, compressions, and movements of the floor slab over time. This leads to the detachment of the vertical and horizontal elements of the hollow bricks from the ceiling.

The solution: the anti-buckling mesh

To secure a floor slab subject to buckling, it is necessary to use a mesh capable of supporting up to 100 kg per square meter. The Soltec system by Cavatorta consists of three main elements:

Mesh
Plastic washer (particular polymer)
Galvanized iron washer

The fastening of the mesh is left to the discretion of the designer, as it is impossible to predict all the variants of concrete and the holding of various fasteners.

Installing the mesh

Installing the mesh is relatively simple. First of all, it is necessary to restore the floor slab by removing the loose parts and filling where necessary. The mesh is laid in the opposite direction to the joists and fixed in two possible ways:

Linear checkerboard installation: one fastening every 44.5 cm, with about 6 fastenings per square meter.
Diamond installation: three fastenings per square meter, faster but requires verification of the sufficiency of the fastenings.

Types of Soltec meshes

Cavatorta offers three types of meshes:

Soltec ESA 16: heavily galvanized welded mesh with 40 microns of zinc.
Soltec ESA 25: heavily galvanized welded mesh with 40 microns of zinc.
Soltec: pre-galvanized mesh with 8.5 microns of zinc.

The first two heavily galvanized meshes have a lifespan of 50 years, while the third, pre-galvanized, has a lifespan of 20 years.

Advantages of the Soltec system

The main advantages of the Soltec system by Cavatorta are:

Certification: the meshes are certified with tests carried out at the University of Parma.
Free software: Cavatorta provides a software to validate the calculations of the designers.
Ease of installation: the system is simple and quick to install.
