Cost of french drain - Structural work is the state of a building is situated, before the finish begins. The carcass lay the foundation for further housing. Sometimes years in the construction phase of structural condition, because there are financial problems, or plans changed.
Factors that Involve Cost of French Drain Preparatory work: The earthworks
- Site preparation of the plot: removing excess trees and rubbish - If you have no wood burned, find someone who saw off the trees in exchange for free wood.
- Remember that the landfill is becoming increasingly expensive. Actual earthworks - Ground worker digs black topsoil away - Through the window construction worker digging holes for your soil (crawl) cellar and possibly the slots for the foundation. Important: ground worker, he must know exactly how deep to dig - If the basement is finished, will navvy backfill around the house spreading Payment of the navvy: cubic meter per hour or other chores you by the ground worker can perform: - Slots for sewerage - Dig the septic tank and fuel tank - Land and any land claim as a house is completely finished Dry suction What? Temporary water sucking up water below works (basement) to be run How long should water be pumped? To basement is finished. It is not a disaster if the basements while the shell is still full of water. How the Drainage System Should Be Made Good drainage is an additional guarantee for a waterproof basement. Especially in clay loam and good drainage areas is particularly recommended because soils are low water penetration. Also on sloping ground is often necessary to drain water dam problems along the high side (mountain side) to avoid. Only in areas where the soil is very permeable (eg sandy soil) and where the groundwater throughout the year on a very deep level, it can be a drain as superfluous. Drainage below the surface There are basically two types of drainage: Check the drainage pipes under the ground surface (below ground level) places, or you can ring them as drainage at the level of the floor lay. The function of the drainage in the two cases is completely different. When the drainage below ground level, it ensures that after heavy rains the water is drained. This prevents large lakes in an area of ​​low permeable soil (clay or silt). Drainage ring Drainage pipes which drain ring at the foot of the basement walls is placed ensure that both ground and as soon as possible water discharged. As a supplement may also drainage pipes under the basement foundation placed the groundwater disposal to come under the floor slab. Placement To ensure proper operation, it is very important both drain the ring around the building and the drainage pipes under the foundation slab in the right possible way. Each type of drainage is in fact a gravel to be placed, and around this draining gravel should geotextile as a filter or membrane separation to be applied. In this way, the silting up of the system is avoided. This method is preferable to a confirmation or coconut fiber geotextiles around the drainage pipes. The classic round drains should always be a minimum slope of 0.5 to 2% will be placed. To prevent the tubes are still bogged down do well to vertical non-perforated pipe to connect the drainage pipe. This allows you to a possible blockage wash away the sand with a garden hose. As an alternative to the traditional system makes it now often use a combination of drainage and formwork. It is about 20 cm high and 6 cm thick hollow profiles with a double function: firstly, they replace ordinary wooden planks as forms of the foundation plate, on the other hand they serve after pouring of the foundation and drainage features with high performance. The drainage system of formwork has the additional advantage that the drainage before the pouring of the foundation and the floor plate can be connected in this way, the building site from the outset for all subsequent work stages dry. Also fall after pouring the foundation slab off a series of operations, such as removal, the cleaning of the formwork boards, and especially the place of the conventional drains. These profiles do first used as formwork for the foundation slab, then drainage. Discharge of drainage water The drainage system is connected to the sewer. Often a well made that all the water from the drainage tubes collected and where appropriate, the water with a submersible pump to the level of sewage charged. That pump must be accessible and it's not a bad idea to have two places. If a piece is, you can run the other so you can get no problems with flooding. Keep in mind also that drainage water from neighbors and that can attract mainly clay and loam areas cause problems. These soils expand when wet and shrink when dry and this may cause a house to fall and rise slightly. In areas where this may cause problems to the drainage way is prohibited.
