Tight Site? Micro Piles Deliver Big Support in Small Spaces

HydroHelp911 installs compact, high-strength micro pile systems for foundations where access is limited or soil conditions demand deeper support.

Small-Diameter Piles with Big Load Capacity

What Are Micro Piles?

Micro piles, also called mini piles or pin piles, are small-diameter, high-strength steel foundations designed to support heavy loads where traditional piers can’t be used. These systems are versatile deep foundation solutions that reach stable soil or rock layers when surface conditions are unstable.

Because they’re installed with portable, low-clearance equipment, micro piles are ideal for:

Confined crawl spaces

Urban sites with limited access

Underpinning delicate or historic structures

Projects needing deep load-bearing support

Foundation Support in Tight or Challenging Conditions

When to Use Micro Piles

Micro piles are recommended when:

Equipment access is restricted or overhead clearance is low
Foundation loads must transfer deep into strong soil or rock
Conventional piers are too large or disruptive
Vibrations must be minimized for fragile or historic buildings

They also perform well in soft, loose, or fill soils where deeper support is required. Our specialized machinery allows us to perform limited access foundation repair in areas where standard excavators or drill rigs cannot physically fit.

How Micro Piles Work

The result is a deep foundation element that resists both compression and uplift forces—even in the tightest job sites.

Drill is inserted into the ground using compact, low-clearance rigs
Steel casing or rebar is installed into the bored shaft
High-strength grout is injected to bond the pile to surrounding soil or rock
Foundation brackets are connected to transfer the structural load
