Because PolyLEVEL dries as a single, solid structure, it’s not susceptible to erosion or deterioration in the same way the sandy slurry used in mudjacking is. Also, it’s completely waterproof and impervious to pest or chemical breakdown, so you won’t have to worry about it breaking down over time. As long as the subsoil below it remains intact, it will continue to support your concrete for the life of your structure!
