Seam Sealing

Prevent water and rodent intrusion by sealing your joints!

Prevent sub-slab erosion and settling by sealing expansion joints. The application of sealing these joints prevents the entrance of water and pests yet allows relative movement at the joint.


An ounce of prevention is a pound of cure!

Upon completion of the concrete raising process, expansion joints need to be sealed. Foam-Tek offers this as an add-on service to any concrete raising service.

The process is simple. The open joint is prepared to create a surface ~1/2” below the surface of the concrete and self-leveling sealant is placed on top of it. Cure-time is dependent on the product used but typically cured within 24 hours.

Unsealed expansion joints lead to excessive concrete movement

Expansion joints, sometimes called control joints, allow for relative movement between structures. Without this joint, there is a higher risk of cracking concrete. Over time, the material placed in these joints will break down leaving a path for foreign objects and water to pass to the underside of your concrete. This can lead to movement of your concrete due to soil erosion and freeze/thaw cycles.

Specialty Concrete Maintenance to Rejuvenate your Property

What are the most common applications for joint seal?

  • The joint between your driveway apron and garage floor
  • Sidewalk Expansion Joints
  • Driveway Expansion Joints
  • Pool Decks
  • Patios
  • Warehouse Floors
  • Highway
  • Curb and gutter
  • Concrete door landing pads

What causes joints to “unseal”?

Expansion joint material breaks down over time:

Have a gap between your garage floor and driveway apron? Freeze thaw cycles exercise this joint and cause it to deteriorate. In many cases it’s held in only by pressure from the adjacent slabs and once this pressure goes away, can fall into the non-core filled frost footing below.

Concrete Cracks:

Control joints are strategically placed during the install process. They may be cut with a saw, or formed with a special tool. The intent is to relieve curing stress in the slab by creating a controlled weak-point for the slab to crack at. The crack itself can now become an entry point for water.

Sealant has a finite life:

Regular maintenance is needed to keep expansion joints sealed. Environmental elements (UV Rays from the sun, temperature swings, rain/snow, etc) work to break them down over time.
