Hydro-Guard BG is a single-component, non-fibrated, asphalt modified, neoprene waterproofing membrane designed to provide highperformance below grade protection from damage incurred by both positive and/or negative side water pressure.

This vapor permeable membrane is applied over concrete substrates and allows moisture vapor to escape to prevent blistering and delamination of the applied membrane, while prohibiting infiltration of moisture through foundation walls and footings, retaining walls and planter boxes.

Hydro-Guard BG also exhibits excellent adhesion to damp surfaces.
