Asphalt concrete or paving slabs what to choose - Today there are many ways for improvement of territory .However, most developers face when building a house with the following problems : asphalt, concrete or paving slabs - what to choose and what characteristics of the coating should pay attention to ?
Consider the pros and cons of each coating , in order to protect you from rash decisions and unnecessary costs .
Asphalt coating - pros and cons
Asphalt is a traditional coating, which is used for improvement of the territory near the house. Asphalting initially involves selecting soil and subsequent device base (gravel or GPS) .
The coating is 4-5 cm, which is enough to withstand regular pedestrian loads and movement of cars . To withstand large loads Recommend laying asphalt in two layers.
On average, such a coating is placed for 2 days, and it can last 7-10 years , it all depends on the quality of work performed , as well as operating conditions . However, in any case, for adjoining areas is advisable to use a fine-grained asphalt concrete - a material that go smoother and aesthetically looks more attractive .
Asphalt one , but a significant disadvantage - at high temperature increases the evaporation of bituminous resins , which negatively affects the ecological environment and state residents.
Concrete cover - pros and cons
Concrete device assumes the following works : the choice of ground floor foundation , reinforcement, form work device , pouring concrete ( concrete thickness in finished form shall not be less than 10 cm) , finishing the finished surface .
Test new coating " strength" just does not work , because the final hardness of the concrete acquires only after 28 days . However withstand pedestrian load cover is quite capable in 2-3 days . Service life of concrete is 5-7 years.
Concrete has a higher strength than the asphalt laid in a single layer . That's just the coating along with advantages also has several drawbacks. For example, concrete is very poorly tolerate temperature changes , though it " works" in violation of stacking technology .
Therefore, when laying concrete pavement must be provided device expansion joints , as well as monitor the monolithic coating. Indeed, in the presence of gaps and cracks in them is bound to water falls , which at low temperatures freezes and expands , which causes disruption of the coating integrity , and eventually - to destroy it altogether .
Paving stone - pros and cons
In this case, the device also requires a base, which acts as sand ( 10-15 cm). Deadline for laying of paving slabs will be slightly higher compared to the arrangement of asphalt. Thus such coating is capable to serve 2-3 times longer than asphalt pavement .
The advantages of the material may include a wide range of colors , durability, aesthetic appeal , portability (if necessary replace one tile to violate the integrity of the coating is not necessary) , environmental cleanliness , lack of puddles due to the drainage system .
