HOME ABOUT SERVICES PROJECTS SAFETY CONTACT EQUIPMENT SALES & RENTALS (210) 342-5261 Post Tension Rock / Concrete Anchors Post-tensioned rock and concrete anchors consist of high tensile strength bars or strands installed in drilled holes which are subsequently tensioned.The anchors provide lateral and vertical load capacity for the installed structures to resist movement. The anchor bottom is bonded to rock or concrete by a cement grout, resin, or can be fixed by a mechanical anchor. The upper portion, or free length, is initially left ungrouted for prestressing; then subsequently grouted to lock in the tension and provide additional corrosion resistance. Rock anchors are used as a cost effective solution to tie down and tie back dams, towers, bridges and other critical structures, for seismic retrofitting, to anchor raft foundations below the groundwater table, and to secure caisson bottoms. Anchors have the design advantage of being able to provide support at hundreds of feet in depth with relatively limited access and disturbance. Corrosion resistant anchors are also available should the project be located in a harshly corrosive environment.

HOME ABOUT SERVICES PROJECTS SAFETY CONTACT EQUIPMENT SALES & RENTALS (210) 342-5261 Abbott Biotechnologies - Storm Water Wells Location: Puerto Rico This project consisted of twelve (12) drilled shafts to function as wells (to inject storm water back into the local aquifer); plus one (1) dedicated as a vent shaft. All wells were installed inside a pit several feet below ground level where storm water was collected from overflowing holding ponds. Shafts, 30 inches in diameter and with depths of up to 130 feet, were drilled dry. A slotted PVC pipe was installed and encapsulated in pea gravel to allow water flow. The top was covered with several layers of gravel and a geo-synthetic fabric to prevent fines from reaching injection wells.
