Joint Sealing
The process of joint
sealing is used to protect concrete and asphalt from
water penetrating through the surface. When joints or
cracks are not sealed, water penetrates through the
joints and cracks of the pavement and compromises the
sub-grade. If the sub-grade is undermined, the quality
of the pavement risks serious damage.
There are several types of sealers including polymeric
hot-applied sealant, polyurethane elastomeric sealant,
ultra-low modulus |
silicone, semi-rigid
epoxy and neoprene compression sealers to name a few.
The uses vary depending on the intent and specifications
of your job and used in sidewalks, balconies, pavements,
terraces, warehouses, factories, civil structures and
plazas. Most sealers are flexible allowing extension /
recovery of the material with the shrinking or
contracting of the paving at the joint. Some sealers are
semi-rigid designed to support the joint edges and
reduce spalling of the edges caused by wheel traffic. |
