MICROPILES contractor

Forget shaky foundations, Schnabel paves the way for stability. With cutting-edge micropile technology, this renowned specialty contractor conquers the world’s toughest terrain, ensuring dependable structural support.

These ingenious mini-piles make foundation work less intrusive and more precise. They’re perfect for cramped spaces or sensitive areas, minimizing disruption and getting the job done with pinpoint accuracy.

Micropiles squeeze into tight spaces like champs! Their compact installation equipment tackles tricky jobs – think inside buildings, under bridges, or anywhere headroom is limited. Plus, you’ll save your budget because less space means less fuss.

No terrain too tough, no project too complex. Schnabel’s foundation support systems rise to any challenge, tailor-made for your specific needs.

Micropile Solutions

Micropile construction, also known as cicropile foundation, involves the utilization of small-diameter piles, typically 12 inches or less, as deep foundation solutions. Schnabel, an innovative company specializing in micropiles installation, employs specialized drills capable of traversing a standard doorway and drilling under an 8-foot ceiling.

Designed for a variety of applications, micropiles are frequently employed to underpin existing structures. Their installation, conducted inside the structure, generates minimal vibration compared to other deep foundation systems. Additionally, micropiles are an ideal choice for constructing deep foundations in areas with natural or man-made obstructions. The drill systems developed for these smaller diameter holes exhibit superior penetration capabilities through cobbles, boulders, and other obstacles, surpassing conventional drilled or driven-pile systems.

Allowable loads for micropiles typically range between 20 and 200 kips; however, Schnabel has successfully installed and tested micropiles with capacities up to 1,200 kips. In micropiles construction, the primary objective is to utilize these small-diameter piles to transfer loads to more competent underlying ground, ensuring stability and strength in foundation support.

Micropiles construction involves the use of small-diameter piles to transfer loads to more competent underlying ground.

In the most difficult drilling conditions, such as landslide debris, Schnabel has drilled micropiles and used them as soldier beams in permanent tieback wall construction. In difficult subsurface conditions and restricted access, micropiles can be a more cost-effective solution for new-structure construction. 

With decades of experience performing micropiles installation, Schnabel is able to provide the most cost effective micropile solution for your project.

Sub-surface to street level, safely and efficiently.

Micropiles construction is generally used where difficult conditions preclude the use of other types of deep foundations.

Interstate 40

Schnabel designed two tied-back micropile walls to stabilize a landslide that had been eroded by hurricane floodwaters below Interstate 40 in Haywood County, North Carolina.

Micropiles construction provides a cost-effective foundation system using relatively small drilling equipment.

American Trucking Association

Schnabel designed a micropile support system that enabled the construction of a new basement under an existing structure to support the renovation of the historical American Trucking Association building in Washington D.C.

NCDOT contracted Schnabel to design and build a repair that would keep this important interstate open and reestablish the eastbound lane. This successful project was completed during the coldest months of the year and within the timeframe established by the State of North Carolina.
