Monolithic septic tank for 100 years (cheaper than reinforced concrete rings, better than plastic). Installation of a concrete septic tank: why is it better in winter?

The lowest cost and most practical solution for arranging an autonomous sewage system is the option of a monolithic concrete septic tank without pumping.

Many will now say that reinforced concrete rings will cost less. But this is not the case. They cost their money and their delivery to the place "hits the pocket." Delivering bulk materials is much easier than the same rings.

Differences between a monolithic septic tank and a sewage system made of concrete rings

The monolithic version is a solid, one-piece construction made of M400 concrete. There will be no leaks.

As for the concrete rings, this option can flood when the groundwater rises by more than 2 meters.

Installation of a septic tank requires the work of an excavator and a manipulator. No one will give guarantees on concrete rings if they suddenly flood. A monolithic septic tank will last up to 100 years. And if you order a ready-made concrete septic tank from the company, then a guarantee is given up to 30 years.

Many people decide to choose a plastic septic tank. It is quite lightweight, easy to deliver and install. But this lightness is not a plus. A septic tank made of plastic can float or stones will damage the bottom, walls. Often such a septic tank presses with soil.

A reinforced concrete septic tank cannot float like a plastic one. It will not be crushed by soil. Specials give hydrophobicity. additives, which increases its service life. The septic tank is sealed, without joints and cracks. Since there are no seams, waste water does not enter the soil (sustainability). Minuses: heavy weight. Installation of a finished septic tank requires the order of construction equipment.

The main plus of a monolithic concrete septic tank is that it can be installed at any time of the year. Why is it better to do it in winter, look Further.

The frozen soil will withstand any technique required for installation. At a high ground level. water, digging a foundation pit is much easier (the earth is dense and solid). In winter, it will be cheaper to make a pit, because there will be no need to order pumping equipment to pump water out of the pit. A monolithic septic tank can be buried using frozen soil. The icy ground will not harm.
