DEEP FOUNDATION / UNDERPINNING

HGS performs three major types of deep foundation / underpinning:

Helical Anchor Systems

Helical anchor system  is with helical bearing plate and shaft combination are hydraulically advanced to load bearing strata to provide both compression and tension applications

Minipiles

Minipiles is using conventional pipe pilings for underpinning, new construction and limited access applications where only compression is needed

Cast in place augered pilings

Cast in place augered pilings are grouted pilings constructed by drilling a continuous flight hollow stem auger to a specified depth.  Cement based grout is then pumped throughout the auger as it is slowly withdrawn

CONCRETE REPAIR / REHABILITATION

Repair of deteriorated/damaged concrete requires intricate knowledge of material, repair geometry and coefficient of thermal expansion.  HGS has the experience and resources to tailor your concrete repair project to your specific needs.  We use only state of the art materials and techniques to achieve repairs that will not only return your structure to its original state but will also last for the life of the structure.

HGS performs three major types of chemical based grouting:

Spall Damage Repair

HGS uses only the top of the line high tech repair materials to replace damaged or deteriorated concrete and rebar

Epoxy Injection

By using both high and low pressure techniques and with their extensive knowledge of available products HGS can economically repair cracked beams, columns, and slabs.  We use only top of the line equipment and materials to assure a repair that will exceed expectations

Carbon Fiber Reinforcement

Through the use of cutting edge Carbon Fiber Reinforcement strips and roll material HGS can repair damaged columns, double tees and structural slabs. Damaged concrete members can often be repaired to standards that exceed the original bearing design.
