heat insulation if you've ever had to build a house you know how important insulation is this is especially true for the builders whose work we're showing you now the installation process consists of several steps each of them should be carried out carefully and thoroughly the first step is preparing the wall the worker make sure the surface is dry and then treats it with a layer of deep penetrating primer this composition improves adhesion between the surfaces and protects them from the harmful effects of humidity the next step is installing a metal starter strip it's important to position it parallel to the ground otherwise the installation material won't be laid properly after that the adhesive compound is mixed and the workers start laying the insulating material in this case polystyrene foam sheets first glue is applied to the inside of the sheets and then they are attached to the wall at this stage the Builder checks each installed board with a construction level in this way the entire surface of the wall is covered the joints between the sheets are filled with special foam styrofoam is not a very solid material so the wall is then polished to make it smoother windows are also insulated the sheets are shaped as needed using a regular knife in the most exposed places polystyrene foam is reinforced with a metal mesh to avoid damage production of reinforced concrete panel construction that is the construction of buildings made of reinforced concrete's is currently very popular now I'm going to show you how the slabs which later become part of the buildings are created the raw material is stone chips and sand their ratios and types can vary to achieve certain characteristics this compound is delivered to a huge industrial mixer via a conveyor belt and is mixed to obtain a homogeneous viscous consistency in this case a reinforced concrete panel with a pass in is made the template is cut out of special foam beforehand the resulting letters are placed on the bottom of the mould in which the mixture will be poured later the first is necessary to reinforce it the workers put metal bars along the mould the pressure on the metal is transferred to the concrete making it more resistant to cracks for this purpose the bars are tensioned with a hydraulic mechanism finally the mold is ready for concrete casting in this case the workers make a sandwich of two concrete slabs and an installation filling therefore when the first layer of concrete is poured the insulating foam is placed on top it is also covered with reinforcing bars and covered with concrete the surface is fastened and left to dry for 12 hours then the worker treats the pass at the surface with a sandblaster to give the products that required effect the concrete takes another three days to gain strength after which the panel is ready roof waterproofing the construction of any house involves the installation of a waterproofing system otherwise the result of all the hard work will be ruined after the first rainfall the video shows builders laying a waterproofing layer on the roof however they use an unusual material this is shingle lament by the american company grip right these are synthetic roof base trees designed to replace the felt which is used traditionally the material stands out due to its light weight these builders chose shingle Ament because it's five times lighter than felt so it's easy to lift it to high grooves both sides of the shades have a non-slip coating which also makes the work easier the material has a high tensile strength which makes it more durable and more resistant to negative external influences the installation material is supplied in a large wide role to cover as much roof space as possible the more material the role contains the less time it takes to transport it take a look at the pattern these lines guarantee and ease the installation of the finishing material glass tile mosaic small tiles are the most common pool of finishing material despite the fact that construction workers have to install mosaics on almost every construction site in the world it is a complex procedure that requires skill and experience in this case the builders are replacing the old coating with a new one builders remove the old mosaic with a hammer and a chisel and other tools before starting the cleaned surface is smooth glass mosaic is a flexible cladding material consisting of a large number of small tiles it may seem that each tile is laid individually but it is not small parts are fitted on a special plastic mesh and placed on the wall in sections the size of these sections can be changed if necessary tiles are attached for the special waterproof adhesive in addition the workers grouts the joints footpath repair concrete is a strong durable material but even so it will eventually collapse under the influence of external factors the builders we're now showing you are repairing various types of damage to the concrete pavement that soon as they use our simple bow so the work is mainly done by skilled hands first of all the concrete is mixed small cracks are easy to treat they're cleaned brushed and filled first with a special compound and then coated with concrete using a small trowel when it comes to repairing a wider crack in his first increased in size however strange that may sound then it is cleaned wetted filled the solution and leveled now the master starts repairing the edges of the footpath first as in previous cases the damage is cleaned then the broken concrete is removed because the surface on the edges must be hard and strong then the master drills a hole in the concrete and sticks and metal barring twists and then makes a supports to shape the edge of the path the concrete is then poured into the hole you can even replace an entire section of the path yourself old concrete and excess soil are taken out once again the worker makes a wooden mold to pour the concrete he sprays the wood with oil to make it easier to remove it later first a thin layer of sand is poured into the mold and compacted and then the concrete is cast bioclimatic pergola the last masters we're going to show you today created a complex wooden pergola with their own hands without using any special equipment the work begins with the preparation of supports the first part of the fastening element is mounted in the asphalt the second part is attached directly to the wooden supports thanks to these elements the supports can be positioned perpendicular to the floor and securely fastened then on these supports the builders attach the cross beams part of the weight of the structure is assumed by the building which is why the beams are attached to the wall of one end the main feature of the future pergola is that the boards which function as a roof can rotate to enable the wooden blades to move the experts fix them in special rotating modules and they in turn are mounted along all the cross beams beforehand making a beautiful and very practical pergola on a hot day you can close the blades to keep away from the Sun and if it's cloudy you can open them letting in the light
