VOLSEAL 200 is a single component, surface applied material, which waterproofs and protects concrete in-depth. It consists of grey Portland cement, specially treated quartz sand and a compound of active chemicals. VOLSEAL 200 is supplied in powder form in 25 kg tubs, and needs only to be mixed with clean water prior to application. When VOLSEAL 200 is applied to concrete surfaces, the active chemicals combine with the free lime and moisture present in the capillary track to form insoluble crystalline complexes. These crystals block the capillaries and minor shrinkage cracks in the concrete to prevent any further water ingress, even under hydrostatic pressure.

In addition to waterproofing the structure, VOLSEAL 200 protects concrete against seawater, wastewater, aggressive ground water and certain chemical solutions. VOLSEAL 200 is not a decorative material.

Typical applications include surface waterproofing, water bearing structures, tunnels, foundations, dock gates, retaining walls, lift shafts, dams, bridge decks, reservoirs, swimming pools, sewage treatment and coastal defences.
