Cracks in as­phalt and bi­tu­men pave­ments al­low wa­ter and veg­e­ta­tion to pen­e­trate the sur­face which causes pave­ment ma­te­rial fail­ures. Fail­ure to seal these cracks and re­move veg­e­ta­tion will re­sult in fur­ther crack­ing, pot­holes ap­pear­ing and even­tu­ally a ma­jor pave­ment break­down, lead­ing to un­nec­es­sary ex­pen­sive re­pairs. To min­imise the wa­ter in­fil­trat­ing the pave­ment base we rec­om­mend crack seal­ing with a hot poly­mer/ rub­berised bi­tu­men sealant, this can help to pre­vent fu­ture pave­ment prob­lems and pro­long the sur­face area be­fore a full over­lay or com­pletely new sur­face is re­quired. Crack seal­ing is a prac­ti­cal and cost ef­fec­tive mea­sure for the main­te­nance of roads, carparks and drive­ways, when com­pared to un­der­tak­ing other more ex­ten­sive works such as resur­fac­ing and re­con­struct­ing.
