MasterSeal 930 bandage was applied onto MasterSeal 933 moisture tolerant adhesive to seal the vertical and horizontal joints. MasterSeal 588 was applied to the concrete by brush in two coats of 1mm per coat.

MasterSeal 588 White was applied followed by a second coat of MasterSeal 588 Grey. MasterSeal 588 forms an elastomeric membrane in dry conditions and when fully immersed, which accommodates any potential movement in the structure once filled. MasterSeal 930 bandage, MasterSeal 933 adhesive and MasterSeal 588 elastomeric membrane are all Regulation 31 approved for use in contact with potable water.
