Common issues and queries you can face
Precast kerbs
Precast kerb units can be damaged, dislodged or broken by vehicle traffic. Often, kerb units are dislodged by vehicles striking the kerb units.
Drainage units
Heavy-duty kerb units and drainage units can be dislodged by accidental wheel loading. The existing sand/cement bedding can break up under traffic loading, resulting in settlement. Often, the bed thickness is limited on bridge decks and conventional sand/cement mortar is unsuitable.
Use appropriate mortars to comply with HA guidance
Use resin-based bedding mortars for reinstatement of heavy-duty drainage units to comply with Highways Agency guidance. For precast kerbs, use a shrinkage-compensated, rapid-setting, cement-based bedding mortar to comply with HD27/94.
