What screed?

Screed - a layer in the construction of buildings necessary for the adoption and transmission of loads to the lower layer of heat or sound insulation.It is used in low hardness of the underlying layers to create a flat surface, ensuring laying overlying layers (waterproofing of the roof or covering parquet).
not entirely clear definition, is not it?If we generalize this layer between the substrate and coating which serves to cover the base.the definition of "tender" is sometimes applied.

Types Tightening what screed should I choose?

Before you think about choosing a version of "tender" is necessary to determine its exact destination.That is, you must look 2.03.13-88 "Floors" in the SNP.In particular, it is possible to know in what specific cases it is applied, whether the screed on the wooden floor needs;a concrete class is better to use.After reading SNiP need to be determined to a particular embodiment.
So, what are all the same kind of "tenders" exist:

• Team - composed of elements, which are mounted of large-sized sheets and panels - plywood, hardboard, particle board, gypsum fiber board.The design of these parts does not have the large size, so the installation can perform the same person.
  
  An interesting method of modular screed is to use gypsum fiber board materials.In that case the cellulose (pulp), which provides high strength, fire resistance and moisture resistance.Features GVL: thickness 10, 12 mm, width of 1.2 m and a length of 2.5 to 3 m Used for parquet devices, false ceilings, interior partitions, wall cladding, flame retardants in buildings..



• Regular - tie is adhering to the base.Typical example - the CPU is tender, filled directly on the floor slabs without foreign films and layers (expanded clay, sand, etc.) And adhered to the substrate.
• monolithic - in this type of work used heavy sand-cement concrete: DSP (on the sand), in the rubble, foam concrete, expanded clay, foam, etc.

You may have noticed that the main material is concrete that is exposed reinforcement..This allows it to work as well in tension (thanks to the fixture) and in compression.
But there is another option.With the use of expanded clay.

What is a concrete block.How to make the floor screed with expanded clay?

Expanded clay - a highly porous, lightweight, environmentally friendly material from the foam and baked clay usual.Using
keramsit much better cement-sand concrete.Now a number of advantages: in particular, by weight, heat and noise insulation.According to the chemical characteristics of claydite takes precedence over all kinds of lightweight concrete.Due to its high porosity, claydite actually "breathes", that allows you to control (adjust) humidity.Such a design variant does not corrode, rot actually supplied and refractories.It has properties of wood and stone, and at the same time.
One of the greatest works of facilities - the local preparation of the solution, which greatly reduces the cost.Expanded clay due to the small weight easily delivered to any floor and quite cheap, saving both energy and financial costs.
Screed expanded clay will allow to align a large height difference.On it is convenient to stack or to lay any floor covering.This option will serve for many years without requiring maintenance.

Screed on wood floor

special place in the device "tenders" is the screed on the wooden floor.If the above options work, with a strong desire, you can make your own hands, it is necessary to attract specialists to work with wood flooring / parquet.
The main problem is to ensure the evenness of the deck, so you have to check each board for defects.Twig, rot in the tree - all of which can damage your future parquet.

recommend also to contact the experts in carrying out floor screed in the bathroom.Any of your false move can lead to flooding of neighbors.

cost

works Cost of works to perform contraction flooring can vary greatly depending on the region.It is understood that the main costs fall to the material, so it is necessary to calculate in advance the materials for floor screed.On razlichnyhinternet-resource contains online calculators to help you determine the amount of material required to your square footage.
screed is quite time-consuming and energy-intensive process.There are many companies offering assistance in this difficult matter, and if you're not confident that you can do everything well, it is better to turn to these firms.You must agree on a curve is not too pleasant to walk?
