Quick Answer
When managing water around cordwood structures, slope the ground at least 1 inch per foot away from the foundation to ensure proper drainage and prevent erosion. Use a 4-6 inch layer of compacted gravel under the structure's foundation to improve water flow. Regularly inspect and maintain the structure's water management system to prevent damage.
Site Preparation and Grading
Proper site preparation and grading are crucial for effective water management around cordwood structures. When building a new structure, excavate the foundation area to a depth of at least 12 inches below the proposed grade. Fill the excavated area with compacted gravel to improve drainage and prevent water accumulation. Slope the ground around the structure at least 1 inch per foot away from the foundation to ensure proper water flow. This will prevent water from accumulating against the structure and reduce the risk of erosion.
Foundation Design and Waterproofing
The cordwood structure’s foundation should be designed to prevent water infiltration and ensure proper drainage. Use a 4-6 inch layer of compacted gravel under the foundation to improve water flow and prevent water accumulation. Apply a waterproofing membrane to the foundation walls to prevent water infiltration and ensure the structure’s integrity. A 1/8 inch layer of polyethylene sheeting or similar material is recommended for most cordwood structures.
Maintenance and Inspection
Regular maintenance and inspection are essential to ensure the water management system around cordwood structures remains effective. Inspect the structure’s foundation, walls, and roof regularly for signs of water damage or erosion. Repair any damage promptly to prevent further issues. Check the structure’s drainage system, including the grading and gravel layer, to ensure it remains intact and functional.
