NEW DEEP FOUNDATIONS

MICROPILES

Micropile installation during construction of Crystal Bridges Museum of American Art.

With individual pile capacities up to 300 kips and a diameter of 12" or less, these steel reinforced, grouted piles can be installed where other deep foundation elements are not a viable option.

ROCK ANCHORS

Rock anchors at CARTI Little Rock.

Pre-tensioned, grouted anchors used to counter uplift or overturning created by adverse soil or groundwater conditions.

HELICAL PILES

Helical pile installation at Hiland Dairy in Little Rock, Arkansas.

Helical piles use varying diameter helix (plate) sections as the bearing surface of the pile and to pull the pile down into the ground.

ANCHORED EARTH RETENTION

SOIL NAILS

Installing a soil nail at the Harmon Parking Deck, University of Arkansas - Fayetteville, AR.

Soil nails are closely spaced anchors that may be installed horizontally or vertically to stabilize cuts or slopes.

GROUND ANCHORS

Post-tensioning a rock anchor per PTI spec at CARTI Little Rock.

A ground anchor can be installed in soil and some types of rock.  Ground anchors are pre-tensioned after installation.

TIEBACKS

Installing a helical tieback for excavation support at the Mill Creek Bridge in Arkansas.

Tiebacks are used to resist lateral force in a vertical wall or face.  Designs include helical tiebacks and grouted anchors. 

STRUCTURAL UNDERPINNING

HELICAL PIERS

Helical pier / Helical pile installation.

When used for underpinning or foundation repair, helical piers can be an economical and efficient solution for both compression and tension applications..

MICROPILES

Underpinning a building in Fort Smith, Arkansas with micropiles.

Coupled to a structure by way of a bracket, grouted socket or pile cap, micropiles can be used to underpin or add bearing capacity to a structure - even in low overhead or limited access locations.

STEEL PIERS

Push piers or driven piers for underpinning a structure.

Hydraulically driven steel push piers are a viable option for compression loading applications.  Push piers are not used when tension loading is required.

SUPPORT OF EXCAVATION (SOE)

SOIL NAIL WALLS

Permanent soil nail wall for Kiewit at the Fort Smith Pavilion shopping center in Ft Smith, AR.

A soil nail wall can provide temporary or permanent support for slopes, faces, or cuts.

TIEBACKS & ANCHORS

Drilled and grouted tieback anchors with whaler installation in Little Rock, Arkansas.

Tiebacks and anchors are used to provide lateral support for SOE installations such as sheet piles, soldier piles and other vertical shoring systems.

SOLDIER PILES / LAGGING

H-piles with shotcrete lagging and tiebacks for the University of Arkansas Vol Walker Hall ESS.

Vertical soldier piles (h-piles or micropiles) are installed at regular intervals and joined with horizontal lagging to form a retaining wall.
