Sika®-1 Waterproofer is an aqueous solution containing complex colloidal silicates. In the presence of water these swell and block the capillaries and pores in the applied sand/cement renders, screeds and mortar to provide an effective barrier against the transmission of liquid water. Used for structural screeds to resist water pressure below ground when used in conjunction with Sika®-1 pre-batched mortars; waterproof renders to resist moisture above ground; internal below ground basement waterproofing; general waterproofing admixture for mortar.
