Slurry designs are performed free of charge. However, the following conditions apply:
- Only Colas clients are entitled to a Colas slurry design.
- A minimum binder order is applicable.
- Aggregate should conform to (at least) the grading requirements for crushed aggregate intended for use in slurry seals, as specified by COLTO.
In cases where conditions 2 and/or 3 are not met, the Colas Central laboratory would still be happy to advise clients on the optimum mix proportions for a specific slurry mixture, based on experience and by conducting minimal testing
