The technology for erecting a strip foundation provides not only with concrete pouring, but also laying from ready -made elements.
As parts of the strip foundation, you can use, for example, brick or larger blocks. Such a foundation has established itself well when erecting buildings with increased load on the base. Often the strip foundation is used in construction on bulk soils or subject to seasonal progresses. For a filling foundation, plywood can be used as a formwork for the foundation with a thickness of 12 mm to reliably hold the concrete mixture.
Preparation for styling
Preparation for laying the foundation begins with the digging of the pit or trench. The foundation pit is used in the manufacture of the foundation of large elements, because large -sized blocks are inconvenient to lay in a narrow trench. After excavation of the soil, the bottom of the pit must be valued and make a pillow of sand and crushed stone to divert excess moisture. Also prepared in advance a solution for fastening parts of the foundation.
Laying
Bricks or blocks are laid on each other and are interconnected by a solution. To increase the strength of the foundation, a mesh of reinforcement is laid between the rows of elements.
The use of special blocks, the size of which is determined by the width of the foundation, will help speed up the laying. These blocks can have special ridges and grooves, which contribute to better adhesion of the elements to each other, and makes it easier to align them horizontally. The disadvantages of building blocks for the foundation can be attributed to the rather large weight and the need to use lifting equipment for their installation. However, this is justified by the reduction in the time of work.
Waterproofing
In order to prevent the destruction of the foundation under the action of ground moisture and increase its service life, it is necessary to waterproof the foundation. Waterproofing is usually performed with special roll materials. The foundation is covered with bituminous mastic, overlapping waterproofing sheets are laid on it without gaps, voids and gaps. Plaster is applied over the insulating material. The thickness of the plaster layer and its composition are selected in such a way as to obtain a uniform coating without cracks and voids.
This is a very important requirement, since the presence of air bubbles can further lead to the formation of cracks. Through them, moisture from the atmosphere or soil will seep into the foundation, and this will lead to the appearance of mold or fungus. Through the foundation, parasites can enter the basement and lower floors of the building.
