Expert Verdict — Reviewed by the SuperArbor Pro Desk
Drainage boards are most valuable on buried walls where hydrostatic pressure builds, so plan the roll orientation so the drainage path terminates at a footing drain or weep system. Overlap adjacent rolls per the manufacturer's direction to keep a continuous drainage plane. In most below-grade jobs this roll pairs directly over a self-adhered membrane such as Blueskin WP 200.
Excavation and below-grade installation carry trench and shoring hazards; follow OSHA excavation requirements and site safety plans.
