Quick Answer
Digging a trench around your winter shelter is crucial for drainage to prevent water accumulation and freezing. A trench should be at least 6-8 inches deep and 12-18 inches wide. This will help to redirect water away from your shelter and prevent damage.
Importance of Water Drainage in Winter Shelters
Water accumulation around your shelter can lead to ice formation, which can compromise the structure’s integrity. Freezing water can also lead to damage to the surrounding terrain, making it difficult to maintain your shelter. In extreme cases, water accumulation can cause your shelter to collapse.
Designing the Trench System
To design an effective drainage system, start by identifying the highest point of your shelter’s surroundings. From there, dig a trench that slopes downward at a rate of about 1 inch of drop per 12 inches of length. This will ensure that water flows away from your shelter. The trench should be at least 6-8 inches deep to account for frost heave and prevent the trench from becoming blocked. A width of 12-18 inches will allow for easy maintenance and prevent clogging.
Maintenance and Upkeep
Regular maintenance of your trench system is crucial to prevent clogging and ensure proper drainage. Check the trench for debris and ice buildup regularly and clear any blockages. You should also inspect the trench’s slope to ensure it remains effective. By following these guidelines, you can create an effective drainage system that protects your winter shelter from water accumulation and damage.
