Tiebacks secure a residential foundation pad for a future tennis court..

TIEBACKS and TIEDOWNS can be installed in virtually any ground condition using rotary, percussion or down-the-hole hammer tooling.  The critical design elements are the capacity (Kips), length of unbonded zone, corrosion protection (Class I or II or none), grout cover (usually 1/2"),  and testing specs.  The contractor usually selects the bonding length, grout additives,  tendon supplier and provides a shop drawing.
