Commercial floor and ceiling slabs may lose load-bearing capacity over time due to exposure to vibrations and moisture, which can corrode the internal reinforcing steel bar and cause the slabs to crack. They may also require updating for building codes or change of use projects. The HJ3 Civil and Commercial Slab Strengthening Systems provide the strengthening and confinement you need for your project at significant cost savings vs. replacement.
