When planning to break up the lawn on your own lawn, you should carefully familiarize yourself with the entire step-by-step algorithm of the planned works. The need for a drainage system depends directly on the quality of the soil for each specific area to be cultivated. If water stagnation caused by irrigation or rainfall is not characteristic of the site to be improved, the organization of the drainage layer is usually optional. But for a full-fledged lawn area, which will please the eye of the owner during the whole season and will eliminate the need for unnecessary subsequent alterations and corrections, it is still necessary to provide for the implementation of this stage of lawn breakdown.
Preliminary analysis of site features
The type of soil to be mined in this area should be analysed and determined. It is also necessary to read the area provided for landscaping activities. The creation of drainage for the lawn drainage area is particularly relevant for clayey and loamy soils. Having determined the size of the green area, it is possible to start digging out the site, providing the most even surface on the whole excavated area.
Only if the area being cultivated has a high sand content and low clay content can the question of how to properly drain the lawn be considered resolved.
In this case, the soil itself acts as an excellent system of natural drainage, saving future lawns from the harmful effects of excessive moisture and stagnation of excessive or normalized sediments.
Opinions of experts on planting trees and shrubs in this issue differ, but to ensure full grass cover of the soil with lawn crops it is necessary to secure and lay down the structure of drainage of local type. Such a system will protect against excessive water due to unforeseen rains and overwetting of the site in the subsequent period of snowmelt in spring.
Modern types of drainage systems
With a competent approach to the creation of its own lawn area, the drainage layer is laid first of all after the completion of digging, cleaning and levelling works. To date, the following systems are the most effective:
lower-level system designed for drainage of running lower-level water;
the upper one, which effectively removes moisture entering the soil (e.g. rain, snow)
local, used in part for landscaping areas.
Many owners of their own homes use this system. Such works are carried out in the shortest possible time and are quite simple:
From 15 to 20 cm of fertile top layer;
A layer of subsoil filled with small stones, gravel and coarse sand is laid in 5 cm;
It is not superfluous to pay attention in advance to how melt water flows down and what movement of accumulated water on the site as a whole.
Methods of construction of main types of drainage
If the developed plot of land is sufficiently studied, and its individual characteristics are determined, it will not be difficult to think over and recreate an effective drainage system. It is enough to follow some simple rules.
Laying the main layer
Special attention should be paid to the owners of areas with a clear predominance of clay in the composition. Such a layer will be quick and will dissipate excess water. The works are carried out in the following order:
Backfilling of stones, gravel, broken bricks with thickness from 10 to 15 cm;
the same amount of sand or fine sifting is placed;
The final layer is the soil itself, which is intended for planting lawn crops.
It should be noted that each layer is carefully compacted.
Drainage system of canal systems
The drainage system is used when the layer system does not, or simply cannot, bring the desired result. In this case, it is necessary to plan the construction of wells or drainage ditches, while providing the system created with maximum decorative effect. The peculiarity of the channel system is to lay ditches taking into account the movement of melt water.
Drainage scheme at the site
Drains – a system for particularly difficult areas
If planting is planned in wetlands, but the previous methods will not be useful. In this case, the best solution for removing excess water is a drainage system. The placement of drains is the laying of several asbestos-cement pipes. In such a system, it is essential to provide a directional drainage system.
