DEEP FOUNDATION WITH GEOTEXTILE
Kortex® Tube is woven geotextile (in tube form) encased the gravel-sand piles.
When founding with gravel piles, woven geotextile made of high strength PET - Kortex Tube
can be beneficially used. This geotextile is twisted on a circular loom and the pile is
covered by it. Its application is necessary in case of soils with shear stress T < 15 kPa (peat, clay).
Basic advantages of founding using Kortex® Tube material under such conditions:
- absorbing of shear forces which could lead to pile shearing and its failure
- prevention of undesirable mixing of gravel sand with surrounding fine-grained soil
- stabilizing aqueous conditions in subsoil
Other benefits of application:
- achieving an even settling
- gravel sand piles improve foundation conditions: they drain off, increase modulus of elasticity of foundation
- safe value of shear strength is achieved relatively soon after completing the pile so that it can be loaded already after short period
- no need for a dense network of piles, such as it is the case with concrete piles
- piles can be driven even in winter (up to approximately -10°C), construction is accelerated considerably thanks to this fact - piloting can be done in winter while
consequent geotechnical operations can be completed in spring
- this type of construction is more environment friendly
