Product Description

Betoseal W50 is an hydrophobic, water repellent liquid admixture for cementitious mixtures that significantly reduces the absorption of water in hardened concrete and prevents efflorescences.

Field of Application

Betoseal W50 is particularly suitable for applications where concrete with a high water repellent effect is required, but only in conditions in which there is little or no hydrostatic pressure. Use Betoseal W50 to prepare concrete with a low rate of water absorption and to prevent the outcrop of efflorescence stains. Betoseal W50 is especially recommended as an integral hydrophobic waterproofing for semi-dry concrete such as concrete blocks, sump pits, kerbstones, pavers, etc.
