PolyPier Brings a Sidewalk Back to Level
A sinking sidewalk isn’t just an eyesore, it’s also a tripping hazard. PolyPier® will get your sidewalk back on level ground.
The PolyPier® system provides a new, state-of-the-art solution to a very old problem: sinking or settling concrete.
Virtually every type of concrete flatwork (slabs, sidewalks, driveways, runways, patios, and more) will be susceptible to sinking if the supporting soil is loose, weak or prone to compression.
Concrete also will sink when support soil is washed away.
When it’s your sidewalk that sinks or settles, you may be setting yourself up for a costly lawsuit.
Depending on the circumstance and local laws, you may be liable if someone is injured on your sidewalk.
The PolyPier® concrete-specific geotechnical foam system is lighter in cubic foot weight than traditional cement slurries, easier to apply, less intrusive and simpler to clean up.
It’s less invasive than traditional mudjacking and more cost-effective than total concrete tear-out and replacement.
How does PolyPier Work?
When the PolyPier® system is used, ⅝-inch holes are drilled in the sidewalk to be used as injection points.
PolyPier® polyurethane foam is injected through the holes, filling the space beneath the sidewalk.
The foam then raises the concrete to its original level position.
PolyPier® is specially formulated for subgrade (beneath concrete) use. Systems are available to perform in both wet and dry soil conditions.
All PolyPier® polyurethane systems are tested per ASTM test methods, which include (but are not limited to): density, compression strength, tensile strength, dimensional stability, closed-cell content, water absorption, and shear strength.
All PolyPier® systems are closed-cell, by design, which reduces or eliminates water infiltration around slab sections.
Voids or cavities under the concrete that may have been created by improperly compacted soils or poor drainage can be filled with the PolyPier® foam to ensure no further settlement occurs.
