Bulking out webercem five star repair concrete

For larger sections it will be more economical to utilise the shrinkage compensating properties of webercem five star repair concrete by bulking out using a selected single size or graded rounded aggregate, for example Pea Shingle or similar.

webercem five star repair concrete can also be bulked out with 5 –20mm graded crushed limestone aggregate. This particular aggregate has proven AAR resistance.
