A pile-screw foundation is much cheaper than the simplest strip foundation, it is built much faster, and at any time of the year and does not depend on the topography of the site. Its only significant drawback is the unattractive empty space between the ground and the first floor.

To eliminate this shortcoming, resort to various methods of finishing.

Screw pile - a metal pipe with threads at one end and a flat head at the other, somewhat reminiscent of a huge nail. Piles can reach a length of 2.5 m, have blades at the end, and not threads or threads throughout the body. To prevent corrosion, the products are covered with ship primer - black.

The empty space under the building not only looks unaesthetic, but also poses a threat to the structure. Evaporation of wet soil, snow and rain getting under the building, grass sprouting - all this contributes little to the preservation of the building, and small animals - from lizards to cats, willingly use this space.

Finishing allows you to solve the listed problems. The general principle of cladding is very simple and cost-free.

1. First of all, the crate is mounted. It is allowed to use a wooden beam, previously impregnated with an antiseptic and a metal profile. The latter option is much more durable, since the tree will not withstand constant contact with wet ground.
2. The dimensions of the frame are determined by the dimensions of the finishing sheets.
3. Insulation is attached to the frame, if necessary, and then the selected finishing material is mounted.

Brick, basement siding, and even simple plaster are used as cladding.

brick finish

This is the most expensive method, and it also requires certain knowledge and skills. If they exist and the costs do not frighten the owner of the building, then this option is easy to implement. It has a lot of advantages:

• brick retains heat much better than finishing materials, so that freezing of the building does not threaten in the most severe frosts;
• in this case, you can safely do without insulation;
• facing brick is elegant and attractive in itself, no additional finishing is needed here;
• no finishing material can compete with brickwork for the duration of operation;
• brick reinforces the pile structure and serves as an additional support.

The disadvantages include the cost of such a solution and the duration of installation: masonry takes time.

basement siding

This option successfully imitates brick and masonry, but at the same time it differs in much less weight and costs much less.

Socle siding is a vinyl panel of increased strength and rigidity. It also features a more reliable docking method and high resistance to wind loads.

Their advantages are:

• ease of installation - finishing can be done in one day, and on your own;
• relatively affordable cost;
• an excellent choice of colors and textures, you can choose the best option for any type of building;
• strength and good durability: plastic does not rot, does not corrode, is resistant to ultraviolet radiation and is designed for 50–60 years of service;
• the plinth can be washed with plain water or detergents.

The only drawback can be called that in terms of durability, the plinth panels are still inferior to brick.

Decking

This is a metal profiled sheet with a zinc coating that protects the steel from corrosion. It is painted in a variety of colors, has a thickness of 9.5 to 0.7 mm and is more than affordable.

Material advantages:

Product disadvantages:

• corrugated board is afraid of damage: a deep scratch damages the polymer coating and the zinc layer. As a result, moisture can get to the steel and in this area the metal begins to rust;
• leaf shape varies within very small limits;
• paint loses intensity and luster over time;
• in fairness, such a cladding is only suitable for buildings finished with plastic or metal lamellas.

Decorative plaster

This option can only be implemented together with basement insulation. Its essence boils down to attaching heat insulator plates made of dense material to the frame and applying a plaster layer on them.

Plates are pre-primed. As a plaster mixture, it is better to use silicone or fiberglass, since they are the most resistant to moisture.

How to insulate the basement of a pile foundation

The disadvantage of the pile foundation is a rather cold floor. And if in the southern regions this is not a big problem, then in the middle latitudes the plinth has to be insulated.

There are many methods of warming. The choice is determined by the height of the pile columns, their location, the material of the piles and the topography of the site.

There are 2 fundamentally different approaches:

• insulation around the perimeter - a frame is built along the base, and a heater is fixed to it. Then the finish must follow:
• if this option is not possible, due to the characteristics of the soil, for example, they insulate the outer side of the floor.

Full insulation scheme

Regardless of which material is chosen for thermal insulation, the general sequence of actions is almost the same.

1. The grillage and piles are waterproofed - this is a necessary measure to prevent the spread of corrosion in cases where the metal structural elements begin to rust and the wooden ones rot.
2. They build a crate for insulation and finishing panels - it is preferable to use a metal profile, as it is much more durable.
3. Fasten the insulating material to the frame.
4. If possible, provide additional work on internal insulation using soil or expanded clay.
5. Mount decorative trim on the plinth.

Thermal insulation materials

Not every material is suitable for basement insulation. Proximity to the ground implies very high resistance to moisture, mechanical strength and at the same time excellent thermal insulation properties.

Preference is given to synthetic materials. Firstly, they do not attract rodents, and secondly, they are highly moisture resistant and not susceptible to mold. Minvata is excluded unambiguously. Basalt can be used, but is very inconvenient during installation.

• The first place among the proposed options is occupied by polystyrene foam and extruded polystyrene foam:

Penoizol has similar characteristics. But unlike polystyrene foam and polystyrene, it allows steam to pass through without passing moisture.

The disadvantage is the same - a rather high price. You also need to take into account the large weight of the product.

Brickwork simultaneously serves as both a heat insulator and a decorative finish for the basement. Despite the high cost, this option is often the most profitable.

Finishing and insulating the basement of a pile-screw foundation is not so difficult. Different materials are used for this, which allows you to choose the best option for each case.
