Slurry Walls / Barrettes

Multiple O-cells® can be conveniently placed in series to test rectangular panel sections or can be located as necessary to test "T" shaped sections. Loadtest has been engaged on several barrette projects and has developed an efficient, cost effective method...

Single Level Bi-Directional Static Load Test

The O-cell is a hydraulically driven, high capacity, sacrificial loading device installed within the foundation unit. As the load is applied to the O-cell, it begins working in two directions; upward against upper side shear and downward against base resistance...

Multiple Level Bi-Directional Static Load Test

Single or multiple O-cells® can be arranged on multiple levels to isolate strata of interest. A zone of interest can be isolated within the 2 levels of O-cells and zone specific data can be retrieved from mobilzing this section. The...

Bored Piles and Caissons

The O-cell® is used in production (proof tests) and non-production (preliminary test) piles either attached to the pile/shaft’s reinforcing steel cage or placed using a steel beam carrier frame...

CFA Piles

O-cells® have been successfully installed in CFA piles to depths exceeding 45 m. Installation of the O-cell does not change the typical CFA pile construction method, however, a modified grout mix is recommended to ease placement into the fresh grout...

Driven Piles

Specially constructed O-cells® can be attached to driven piling. Load testing can be performed on prestressed concrete piles, steel pipe piles and cylinder piles...

How the O-cell works

The O-cell is a hydraulically driven, high capacity, sacrificial loading device installed within the...
