Water repellent soils exhibit hydrophobic properties when dry, resisting or retarding water infiltration into the soil matrix (Brandt, 1969a). Infiltration rates may be reduced by an order of magnitude, even in soils which visually appear to wet “normally” (Wallis et al., 1991).

Capillary forces in unsaturated soils depend on the surface tension of water, the dimensions of soil pores and on the contact angle of the interfaces of the solid phase of soil (soil matrix) and liquid water. The contact angle (angle of wetting) is assumed to be zero, but in real soils is higher, depending on the properties of the thin surface layer ...

Eighteen years ago we called attention to the need of developing water resistant materials as bacterial barriers in the operating room setting1. Possibly as a result of that report, a new industry came into being which now supplies surgical draping to a large number of hospitals and operating units.

WATER REPELLENTS ARE TRANSPARENT COATINGS formulated for the purpose of protecting porous substrates by preventing the penetration of liquid water. Unlike waterproofing materials and sealers, water repellents allow the passage of water vapor and generally are not designed to prevent the intrusion of liquid water under hydrostatic pressure.

Water Repellent Periodic Mesoporous Organosilicas
ACS Nano, 2011This paper demonstrates for the first time thermally induced gradual hydrophobization, monitored quantitatively by ellipsometric porosimetry, of four prototypical periodic mesoporous organosilicas (PMOs) that are tailored through materials chemistry for use as low-dielectric-constant (low k) materials in microprocessors.
