Saber was called in by the First Chinese Baptist Church to To address the trip hazards, Saber utilized a concrete grinder to Installer: Saber Products Installed: 2 x HA 150 galvanized helical anchors with tiebacks and wall plates, 48 linear feet of Nexus Pro concrete joint sealant, and 36 pounds of PL400H two-part, high-density PolyLevel hydro-insensitive foam system Install Dates: Oct. 25, 2018 - March 20, 2019Wall Support and Trip Hazard Removal for Church in Los Angeles
Challenge
eliminate trip hazards within the church campus. The second phase
of the project would involve the stabilization of a tipping wall.Solution
repair the uneven joints. The crew then used 48 linear feet of
Nexus Pro® joint sealant to prevent water runoff from seeping into
the joints and causing future damage.
The crew drilled 5/16 inch holes for the required injection ports.
Then approximately 36 pounds of PL400H PolyLevel® two-part
high-density (4lb) hydro-insensitive polyurethane foam system was
pumped beneath the concrete slab to fill voids, stabilize and lift the
slab. The slab was lifted in a gradual and controlled manner.
To secure a tipping 12x5 foot wall, Saber cored a hole into a support
wall at the front of the structure, and then installed two HA 150
galvanized helical anchors with a hydraulic-powered rotary-torque
drive unit. Tie-backs were used to provide lateral stabilization.Project Summary
