Landscaping Techniques for Moisture Control

Excess moisture in walls is undesirable. It can lead to a myriad of problems, including structural damage, mold growth, and unpleasant odors. Landscaping techniques can be effectively employed to control moisture levels and safeguard your property.

Managing Water Drainage

• Slope away from foundations: The ground should be graded such that water flows away from the building’s foundation.
• Install gutters and downspouts: These effectively divert rainwater from the roof and channel it away from the foundation.
• Use French drains: These are underground perforated pipes that collect and drain excess water from the soil.

Plant Selection and Placement

• Choose drought-tolerant plants: These plants require less water and help control soil moisture levels.
• Plant trees and shrubs at a distance from the foundation: Their roots can absorb moisture from the soil, reducing water accumulation near the walls.
• Avoid planting moisture-loving plants near the foundation: These plants can increase soil moisture levels and contribute to problems.

Soil Amendments

• Add organic matter: Compost or peat moss can improve soil drainage and reduce moisture retention.
• Use gravel or crushed stone: These materials can be added to the soil to enhance drainage and prevent waterlogging.
• Install a vapor barrier: This barrier, placed beneath the soil, prevents moisture from rising into the walls.

Other Measures

• Check for leaks: Regularly inspect plumbing fixtures, pipes, and the roof for any leaks that may contribute to moisture problems.
• Seal cracks and gaps: Seal any cracks or gaps around windows, doors, and other openings to prevent moisture penetration.
• Use a dehumidifier: This device helps remove excess moisture from the air.
