RAM JACK® Helical
Steel Piles
- No rain delays
- No holes to drill. Helicals are
screwed into load bearing strata
- Fast clean installation. No spoils.
- No cure time. Grade beams can
be installed immediately
- Installed below active zone without
casings. No crane required
- Load carried on helix bearing
plates
- Slender shafts reduces heave potential
due to skin friction
- Each pile is tested for bearing
capacity by monitoring the torque
values

Drilled/cased Concrete
Piers
- Rain stops all work
- Drill pier holes
- Must clean up/remove spoils
- Crane required to install casings
- Must wait 28 days for concrete
to cure before grade beams can be
installed
- Piers must be cased if water table
is penetrated
- Depends on skin friction for bearing
- Large surface area susceptible
to heave failure due to skin friction
- No way to test during installation
