|Foundations, car park waterproofing works
We carry out the foundations, car park waterproofing works. We work with a variety of damp materials: Mida, garantgum. Firestone EPDM and so on.
What to consider the installation of foundations:
- Soil layer on a support base must be adequate in severity.
- Circular foundation should not be above freezing level, a threshold which depends on geological conditions (in Lithuania is 1.2 to 1.4 m above the ground).
- Foundation design must maintain the integrity of the technological characteristics of joints, and highly technological inputs.
- Foundation for protection against rain.
- Basement waterproofing properties.
- Thermal insulation properties of the foundation.
- Soil strength.
Before designing the foundation, must be carried out engineering geological investigations. Only then will we have detailed information about soil structure, the strength of the individual layers, groundwater occurrences at depth. It is understood that finding ways to save the building, geological studies will attempt to do the same. In this case, in accordance with the safety requirements to be mined maximum extent possible, the depth of the trench, and some of the research work carried out independently. Trenching will see the structure of soil (gravel, sand, clay), ground water level. The current strength of the soil to check for yourself to fail. To do this, just rely on intuition.
Carry out independent research on the ground it is advisable to pay attention to the construction of the building design integrity, and at the bottom and top of the wall it is advisable to install industry packaging rings.
Choice between conventional shallow foundation design, circular should be selected in accordance with the supporting layer of bedding place, and under the earth freezing conditions. Lithuania a well-established rule that the freezing of the ground from 1.2 to 1.4 meters. But that does not mean that all types of soil ae permafrost , or that all permafrost soils is risible. For example, dry sand or gravel soil freezing temperatures are not risible. Soil rising reason is that it contains water, which is a negative temperature virsdamas ice expands.
Protection of water
Kad statomo pastato pamatas būtų apsaugotas nuo gruntinio (taip pat ir kritulių) vandens būtina įvykdyti dvi sąlygas deramai įrengti drenažą ir priegrindą (zoną su nuolydžiu) aplink pastatą.
Norint palengvinti drenažo darbą, labai padeda tinkamai įrengta priegrinda, kuri apsaugo pastato sienas nuo aptaškymo. Priegrinda turėtų būti įrengiama bent 0,5 m pločio ir su nuolydžiu, ne mažesniu kaip 5 proc. (pusės metro gylyje nuolydis yra nuo 0 iki 2,5 cm). Pati konstrukcija priklauso nuo architekto ar namo šeimininko pageidavimo, nes jų įrengimo sprendimų yra gausu nuo paprasčiausio pabetonavimo iki sudėtingos konstrukcijos išliejimo.
In order to protect the foundation from the ground and rain water must be properly installed waterproofing. Isolated by two planes - vertical and horizontal.
Vertical flashing installed in the concrete foundation to avoid frost-thaw cycles, which gradually destroys a single mass of concrete and the foundation is. The latter installed on the outside.
Horizontal flashinginstalled, the construction of the water content in capillary rise above the walls and does not transmit. It is installed at the top of the foundation.
Installation of waterproofing materials used in a variety of very abundant. However, it should be noted that the most reliable is EPDM waterproofing. This flashing of the high-elastic properties of perfectly and the emergence of possible deformations of the foundation.
