Paths around the adjacent territory of a private house are most often filled with concrete, as it is fast, reliable and not particularly expensive. Unfortunately, most often the pouring of concrete at such facilities is completely far from technologically correct work. Because of this, over time, the concrete cracks, collapses and requires updating. The question arises: is it possible to pour new concrete over the old one?
In this article, we will talk about the rules for working with pouring new concrete on the old one, as well as about the magic material with which you can significantly increase the adhesion between two such layers.
Is it possible to pour new concrete on the old one?
Yes, it is possible to pour a new concrete mixture on the old one, but there are certain requirements. These include:
- The evenness and strength of the old concrete surface: if there are chipped or crumbled parts of the surface on the surface, they should be removed; if there are cracks, fill in.
Cleaned surface: it is necessary to remove all dust and dirt, since these seemingly quite natural elements for concrete can greatly affect the quality of adhesion.- Suitable climatic conditions: in frost, extreme heat, during rain or strong wind, it is not necessary to pour new concrete over the old one, since you can thoroughly reduce the service life of the concrete surface.
How to properly pour new concrete on the old one?
After the surface meets all the above requirements, you can start pouring a new concrete mixture. But before that, you can either moisten the surface or apply a special material to increase adhesion.
By the way, if you want to get a more durable and wear-resistant concrete surface, you can lay a reinforcing mesh on top of the old cleaned concrete layer.
It is recommended to pour new concrete over the entire surface without interruptions.
After pouring a new concrete mixture, it is desirable to harden the surface, for example, with a membrane-forming agent.
Material for increasing adhesion
As promised at the beginning of the article, we will tell you about one material with which your new concrete will not completely peel off from the old one. And this is Tekno AD – a special material for increasing adhesion, which contains corrosion inhibitors and microsilicon.
In addition to having high adhesive characteristics, the material is characterized by high strength, frost resistance, water resistance and vapor permeability.
