Build Science™ 201

Matt and Steve continue their conversation on water management, this time focusing on mitigation and highlighting both rainwater and groundwater control. They begin by discussing a real-world case where the absence of "kickout flashing" led to severe wood rot in a 20-year-old home. This emphasizes the critical role of allowing water to escape rather than merely trying to keep it out. Rain screens, which create a gap between the siding and the structure, are essential for drainage and ventilation, particularly in regions with over 20 inches of annual rainfall.

The discussion moves to proper installation techniques for footing drains, sump pumps, and waterproofing systems, noting that drainage mats and filtered fabrics are key for managing water below ground. Improper installations can result in costly repairs. Both Matt and Steve stress that good water management requires forethought—it's not just about sealing, but ensuring a clear pathway for water to exit. They conclude by emphasizing that neglecting these measures can lead to extensive damage and financial loss.

Builders, architects, and homeowners alike, should consider, "Where does the water go?" in every design. Proper mitigation strategies can prevent major issues, saving time and money in the long run.
