Walk Way Dropping Towards the Building
This section of the walkway was sloping back towards the building and holding water that would often freeze in the winter.
Injection Ports
Two vertical injection ports are seen in this photo. These high pressure ports operate one way in that the material is injected under the concrete slap and cannot escape back out of the ports. Along the building the concrete is raised and what looks like a bead of caulk is actually the trimmed PolyLEVEL™ injection foam that also seams out the water at that joint.
Injection Holes Sealed
Once the concrete was raised the injection holes are re-sealed. (A little larger than the size of a dime)
Walkway Seam to be Sealed
After each piece of the walkway is lifted, the seams are sealed to keep out water.
Sealed Seam
The sealant is a durable flexible material that will block water and not deteriorate in the sun light.
