Polytite N is a premium bridge expansion joint sealer. It is pre-compressed for easier handling.
It is a high-density open micro cell polyurethane foam impregnated with a hydrophobic polymer sealing compound. Polytite N works under its own constant internal pressure to provide a permanent watertite seal eliminating costly water damage as well as allowing for a greater degree of joint movement.
Once Polytite N is installed the material expands depending on the temperature adapting to the width of the joint as well as irregularities.
It is developed to meet all applicable standards of pre compressed sealants, as well as designed to meet the high performance needs of state and Federal DOT projects.
