Roadway / Highway Joint Sealant

The purpose of the joint sealant is to minimize the infiltration of surface water and incompressible material into the joint system. Sealants can also reduce dowel bar corrosion potential by reducing the entrance of de-icing chemicals. Max tech is a leading supplier of  PU joint sealant.

 

PU Joint Sealant / Polyurethane Joint sealant,  urethane construction joint sealant,  It is a wide range of construction applications, mainly for Sealing Purposes, sometimes we also say the General Purpose Sealants, Polyurethane construction sealant, polyurethane sealant, non-staining polyurethane sealant, UV resistant PU sealant, bubble-free polyurethane sealant. It is one component multi-purpose PU urethane sealants for use in expansion and control joints in pre-cast panels, and repair cracks or fills joints in horizontal or vertical concrete surfaces, tilt-up walls, metal curtain walls, window and door perimeters, and glazing details.

FOR MAX TECH, The polyurethane joint sealant, we have two types: Self-leveling joint sealant and Paste state joint sealant. They can be used for the Concrete Roadway /Highway, Airport runway, Concrete Pavement Joint Sealing/Filling.

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.

First Step

Construction joint cutting ​ 

 

Use a cutting machine to cut the construction joints according to the design plan

Construction joint cutting machine
Second Step

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.

Cleaning the Joints
Third Step

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

Pad Backer rod
Fourth Step

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

self-leveling joint sealant application machine
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.

Paste State Polyurethane Joint Sealant

MAXTECH paste Polyurethane joint sealants are the one-part, low modulus, and multi-component urethane sealants in expansion and control joints in pre-cast panels,  tilt-up walls, metal curtain walls, window and door perimeters, and glazing details, and the construction sealant are designed for the toughest applications including roof sealants, foam roof sealants, RV roof sealants, metal roof sealants, metal siding, log homes/cabins, extreme environments and all types of window sealants, also for prefabricated building elements, in joints of rainwater collection pipes on roofs and in rain gutters, insulating joints between precast concrete blocks and sealing of joints of aluminum pipes in HVAC (ventilation) sector.
