Joint Stabilization
Slab stabilization is often required when slabs lack support but may or may not be settled. Slabs can crack when loads exceeding its capacity are applied. Slab/joint stabilization applications require the voids to be filled to eliminate movement and offer support. This type of foam is specifically designed for joint/slab stabilization applications due to its very long reaction time and minimal expansion strength.
It will take longer to expand, allowing for better coverage under the slab or down a joint.
