POLYURETHANE CLAIMED ADVANTAGES VS CERTIFIED MUDJACKING:

Poly: Doesn’t stress the concrete due to uneven coverage.

Mudjacking: Pressurized cement grout evenly spread reduces stress off the concrete.

Poly: 95% closed cell foam repels water.

Mudjacking: Cement grout is not a petroleum based material and repels water.

Poly: Will not shrink.

Mudjacking: Will not shrink, in addition admixtures strengthens final grout placement.

Poly: Up to 250 psi compressive & tensile strength.

Mudjacking: Cement grout offers compressive & tensile strengths of 600-5000 psi.

Poly: Excellent coverage within 1/32 of an inch

Mudjacking: Cement grout can meet or exceed coverage within 1/32 at higher psi.

Poly: Injection holes slightly smaller or 5/8” inch.

Mudjacking: Less 11/4 inch size holes drilled in panel, holding more integrity in the slabs.

Poly: Great lifting capabilities.

Mudjacking: Meets or exceeds lifting capabilities of polyurethane.

Poly: Lightweight 125-250 # per yard will not overburden soil.

Mudjacking: Research indicates slab deflection breaks down foam polyurethane.

Poly: New glorified way to raise concrete.

Mudjacking: Most preferred Mudjacking grout has been used for over 100 years.

Poly: Sub-seals floors.

Mudjacking: Cement grout sub-seals floors at higher compressive strengths.

Poly: Waterproofs walls.

Mudjacking: Portland cement grout and bentonite waterproofs walls.

Poly: Cost effective.

Mudjacking: Mudjacking grout is a fraction the cost of polyurethane.

Poly: Not-recyclable material.

Mudjacking: Portland Cement grout can be added to the recycling process with no additional cost or threat to the environment

Polyurethane is a petroleum-based, toxic, sticky material that adheres to the concrete, rendering it unacceptable at the recycling centers. At some point, all concrete must be replaced. Concrete that has polyurethane attached to it will not be accepted at concrete recycling centers. It must be disposed of at a toxic waste facility. When concrete is removed, it will be the owners responsibility and cost to safely remove and dispose of the toxic polyurethane foam.
