BS EN 14199:2015 PDF Download

BS EN 14199:2015 is a European standard that provides general principles for the execution of micropiles. Micropiles are drilled piles with a diameter less than 300 mm and are used as structural members to transfer actions to the ground. They can contain bearing elements to directly or indirectly transfer loads and limit deformations.

The standard covers various types of micropiles, including those with uniform cross-sections, telescopically changing shaft dimensions, shaft enlargements, and base enlargements. There are no limitations regarding the length, inclination, slenderness ratio, or shaft and base enlargements of micropiles. It applies to single micropiles, micropile groups, reticulated micropiles, and micropile walls.

The material of micropiles covered by this standard can be steel or other reinforcement materials, grout, mortar or concrete, or a combination of these materials. Micropiles can be used in various applications, such as working under restricted access and headroom conditions, foundations of new structures, reinforcing or strengthening existing structures, reducing settlements and displacements, forming retaining walls, improving slope stability, securing against uplift, and other appropriate applications.

It is important to note that this standard does not cover deep mixing columns or ground anchors, as they are covered by other standards (EN 14679 and EN 1537, respectively).
