Joint and crack sealing that keeps slabs level
Most sunken and heaved slabs start the same way: water runs down an open joint, washes out the base or freezes underneath. Sealing the joints stops it.
What we seal
- Joints between sidewalk and walkway slabs
- The gap where a walk or patio meets the building
- Cracks across slabs before they spread
- Joints at curbs, aprons and pool decks
How we do it
- Clean out the joint. Old filler, dirt and weeds are removed.
- Backer rod goes in deeper joints so the sealant bonds only to the sides and can stretch.
- Flexible sealant rated for freeze-thaw movement is tooled smooth, flush with the walk.
Stop the next trip hazard before it starts.
Sealed joints keep water out from under your slabs.
