Sealing concrete expansion joints protects the underlying base and extends the lifespan of the slabs.
Key Reasons to Seal Expansion Joints
➡️Prevent Water Infiltration: A sealed joint stops rainwater, snowmelt, and pooled water from seeping beneath the concrete.
➡️Stop Erosion: Water that drains into open gaps washes away the compacted soil, sand, and gravel base supporting the slabs, preventing slab movement
➡️Prevent Sinking and Cracking: Without a solid base underneath, heavy concrete slabs lose support, leading to uneven settling, cracking, and trip hazards.
➡️ Help Reduce Freeze-Thaw Damage: In colder climates, trapped water freezes and expands, placing extreme stress on the concrete edges and causing premature crumbling or spalling.
➡️Block Weeds and Debris: Filling the gaps keeps out dirt, fallen leaves, and seeds, preventing grass and weeds from taking root in the joints.
