determines the width of the blind area

Decking around the house, or as it is called, blind area - a wide band, often concrete, which is being built on the perimeter of the building.Its main function - is removal of precipitation from the foundation.It allows to enhance waterproofing of a foundation and wall construction at the bottom.In addition, the blind area serves as a decorative element, which makes the appearance of the finished home.

recommended to construct blind area width of one meter.However, its width, in many respects, depends not only on comfortable movement on it and the owner desires, but also on the distance of departure of the roof with respect to the perimeter of the building.To determine the optimal width to the starting point of departure of the roof is added to 30 centimeters.The result of the addition will serve as the optimal width.

Important!In any case, do the formwork already 60 centimeters is not recommended, as the movement on it will not be comfortable and constantly have to rub against the house wall.

How to make the formwork around the house?

consider how to make the casing around the house on their own.The first step is to create a markup.To do this, from the roof edge of the projection is done using a plummet.K line, which turned out, plus an extra 30 centimeters length.However, the line that is drawn from the edge of the roof, not to be considered basic, and the final amount is to measure from the wall.Further, the corners are driven marking stakes, which tied the cord markings.Ideally, all corners should be 90 degrees.

Further, according to the markup, the upper soil layer is removed to a depth of 25 centimeters.Then mounted formwork made of boards or plywood.From the outside formwork is fixed hammered stakes.The stakes will be higher the less the likelihood that a pressurized concrete formwork deformed.Pour sand cushion thickness of five centimeters.The sand is compacted and wetted with water, and then poured on top of 5 cm of gravel.

between the blind area, and the cap is compensating seam from two layers of roofing material.You can also apply to the surface of the cap mastic or polyethylene foam.This is done to ensure that there is no deformation of the blind area shrinkage of the house.After that, put reinforcing steel mesh. Important!If the groundwater is close to the surface, it can be waterproofed by putting material overlap on the wall.

Fill blind area

necessary to make the markup slope before pouring the concrete.Most often, the slope is done from home, and parallel to the wall.The optimum bias is considered to be 3-7 degrees.In order not to miscalculate with him, you need to make it to the pouring of concrete.fill line on the formwork must be below the line of the socket.In order not to be mistaken, labels are transferred via gidrourovnya on formwork.Then from the resulting line is measured below the line, and so on.For better bias control can pull strings.By the wall, they are fixed with quick installation and to the formwork - nails.The best step to accommodate them - about one meter.

Pre-filled with two-meter increments set expansion joints of materials with damping properties.They will not be allowed to crack the blind area when the temperature changes suddenly.Further concrete pouring is done.In the process it is necessary to mount the elements livnevki, if any of your roof.After setting concrete on a string using the rules of the slopes are smoothed to the desired level.Thereafter, the entire surface is covered with polyethylene film to avoid uneven drying and cracking.

Important!If the weather is hot, the formwork around the house periodically moistened with water.
