The self-leveling Joint Application
When building roads in our lives, especially on cement pavements, expansion joints 151.9233.3055 are generally left, which is a structural joint set along the appropriate part of the construction joint direction to prevent thermal expansion and contraction from causing cracks in the structure. Expansion joints and construction joints need to be treated. Otherwise, the impact force caused by traffic on the road surface will easily appear from the expansion joints after a long time. MAXTECH Road joint sealant has a coup to treat expansion joints
Gray road joint sealant can be used for cement pavement to reduce the color difference after repairing and make the pavement look more beautiful. The road joint sealant avoids the cumbersome heating and slotting steps in the use and can be directly constructed. It’s a kind of welfare
Road caulking glue is available in bags, sausage and barrels. The bags with glue nozzles can be directly squeezed into the cracks. The barrels need to be poured with an iron pot or a glue filling machine.
Construction joint cutting
Use a cutting machine to cut the construction joints according to the design plan
Cleaning the Joints
The surface must be hard, dry and clean. The inside of the seam must be cleaned up by shoveling, cutting, polishing, sweeping and blowing.
Pad backer rod
Lay a polyethylene foam strip that is slightly larger than the construction joint in the construction joint, and the depth depends on the construction situation
Applying the sealant Put the sealing glue into the glue filling equipment (seam filling machine, glue gun, duckbill pot), squeeze the sealing glue evenly and continuously, and move it evenly and slowly to ensure that the base surface to be glued fully contacts the sealing glue to prevent Move too fast and generate bubbles or holes
Attention:
●We advise reserved 2mm, otherwise, the sealants will overtop the concrete road.
Reserved gap: Since the construction joint will expand and contract with the change of temperature, the surface should be lower than the road surface after grouting, 3-4mm in summer and 1-2mm in winter.
