HMWM MATERIAL PROPERTIES

! Ultra-low viscosity! Bond strength > concrete tensile strength! High or Low modulus of elasticity! Low surface tension! Cure time! Polymerization inhibited by oxygen

Page 34: PURPOSE/FOCUS/ROLE...GOOD BRIDGE – BAD JOINTS 0 50 100 150 200 250 300 350 400 1234567891011 REGION JOINTS ON THE NHS - 2002 non-def joints def joints

SUMMARYSUMMARY

! All products penetrated ! Lower viscosity went deeper! Some bonding restored! Need to practice caution! Weather sensitive! Has maintenance application
