ConSANDtrate is a specific blend of polymers that when added to dry sand at a ratio of 10 parts sand to 1 part ConSANDtrate yields a custom, on or off-site polymeric sand. By mixing your own polymeric sand for your hardscape, flat rock and paver joints jobs, you not only save money but can also mix your own custom colors. By mixing ConSANDtrate at a ratio of 5 parts sand to 1 part ConSANDtrate makes a more concentrated polymeric sand that can be used around problem areas or as a crack filler for concrete or exposed aggregate slabs.
