TamSeal 20 is a surface applied material which waterproofs and provides in-depth concrete protection. It consists of grey or white Portland cement, specially treated quartz sand and a compound of active chemicals.
TamSeal 20 is a surface applied material which waterproofs and provides in-depth concrete protection. It consists of grey or white Portland cement, specially treated quartz sand and a compound of active chemicals.
When TamSeal 20 is applied to a concrete surface, the active chemicals combine with the free lime and moisture present in the capillary track, to form insoluble crystalline complexes. This is known as crystallisation process. Once the crystals have formed, they remain permanent. These crystals block the capillaries and minor shrinkage cracks in the concrete to prevent any further water ingress. However, the layer will still allow the passage of water vapour through the structure (i.e. the concrete will still be able to “breathe”).
Further contact with water will reactivate the sealing process. Thus the lower depths of the concrete form an integral mass with the surface, which cannot be blown off by hydrostatic pressure. In addition to waterproofing the structure, TamSeal 20 protects concrete against seawater, wastewater, aggressive ground water and certain chemical solutions.
