The use of hollow bricks in construction is a fairly popular solution. There are several main reasons for this:
- Fast and convenient laying of the material;
- The cost and weight are lower from a full-bodied brick.
In this article we will talk about the material that is used for reliable and high-quality fastening of materials to hollow bricks.
Where is hollow brick used?
Despite the name of the material - ‘hollow' - it is a very durable building material. 
It is used for the construction of basement floors, load-bearing walls, various partitions and other elements of buildings that must withstand loads of varying degrees, including high ones.
What are the advantages of using hollow bricks in construction?
There are quite a lot of advantages in using hollow bricks. We offer you to familiarize yourself with the main:
- High heat retention:
Hollow brick up to 50% consists of voids, which can be either through or closed on one side.
It is because of the presence of voids that such a building material is characterized by heat retention, that is, its thermal conductivity is lower in contrast to full-bodied materials. And, as you know, the more voids, the lower the thermal conductivity, that is, the heat is stored better. - Material weight:
Using hollow material, the building will not be weighted down. - The cost of the material:
Due to the presence of voids, the weight of the material is an order of magnitude lower than its full-bodied counterparts, therefore less raw materials are used for its manufacture and, as a result, the cost of hollow bricks is lower.
What material can be used to ensure reliable attachment to a hollow brick?
An excellent solution for working with hollow bricks is the use of chemical anchors. These materials are quite new products in the construction industry, but the masters have already managed to like them very much. 
Chemical anchors are produced in two types: on the basis of acrylic resin and polyester. It is a fast-hardening material that is characterized by high strength and resistance to chemicals.
We offer you to familiarize yourself with the Teknobond 401S chemical anchor based on polyester synthetic resin. Its strength is about 70 N/mm2.
It is the Tekno line of chemical anchors that perfectly copes with the reliable fastening of various elements during construction and repair work to hollow bricks for centuries.
