Decking for the pool - choose the optimal approach to construction

What is a formwork - defined with the view

There are formwork for vertical and horizontal structures, sliding and round or rounded, as well as removable and non-removable, - each kind has its advantages. Without this device it is impossible to build a strip foundation, a pedestal, an overlap, a pool. Pools are built in private houses in the yard or inside the house. The bowl is cast from concrete, this gives the imagination of the designer a space, you can build several levels, steps, descents and other elements.

The quality of the formwork depends on the result of all work, this determines the choice of formwork. There are traditional removable systems - steel, plastic or aluminum, these are sets of parts that are assembled at the construction site. For smooth sections of the pool, it is optimal to use them - the filled concrete is smooth and smooth, evenly distributed, and there are very few defects that require the use of expensive leveling compounds.

But the pool of a private house

is always non-standard, it is stylistically connected with the house, and without self-made wooden structures for projections, steps and curvatures is indispensable. Recently, the flexible formwork Syflex has appeared - it's better than homemade, but even it can not be compared in quality with non-removable.

Preparing for work with fixed formwork

The advantage of a fixed formwork is that, when combined with concrete, it forms a monolithic structure, durable and reliable, becoming an element of construction. The best non-removable formwork for the pool is made of reinforced expanded polystyrene, it is flexible and easy to install. After pouring, concrete of the desired shape is obtained, capable of withstanding colossal loads. A swimming pool with a fixed formwork can be made by hand.

The first thing to do is dig a square or rectangular pit - this will facilitate the subsequent work. The pit size should be 300 mm larger than the desired size of the pool( depth and width).Optimum dimensions - 2,5х2,5 m in width and 2,0 m in depth.

The bottom must be dry. It binds a mesh made of reinforcement with a diameter of at least 10 mm. It can be cooked, but knitted is better. Under it lay the stones so that the reinforcing mesh rises 2-3 cm above the bottom.

Vertical rods are left to fasten the formwork. Then, from concrete, sand and gravel, in proportion 1: 3: 6, concrete is made to fill the bottom. After the concrete is completely hardened, the waterproofing is laid.

How to handle the formwork?

Next, the formwork is assembled - polystyrene blocks, the outer wall of which is thicker than the inner wall and serves as thermal insulation. The first layer of the formwork blocks is put on the rods especially neatly, engineering communications and other elements are laid. Laying blocks resembles the laying of bricks: it is carried out with displacement.

The blocks are connected vertically, there are grooves that close when pressed. After laying the third layer of blocks, concrete is poured, which is necessarily sealed with a vibrator or bayonet method.

Prior to pouring concrete, electrical wiring, water and sewage pipes are laid. The next layers of formwork are laid after the concrete has hardened, and so to the top. Do not forget that you need to organize a filtration system. All communications must first be isolated and only then be encased in concrete and formwork, this will eliminate damage to the pipe material and prolong the life of the pipes.
