Soakaway Not Draining [patched] -

Layer by layer, the storage volume shrinks. The “void ratio” drops from 40% to 10%. Eventually, the soakaway is a bathtub of mud, not gravel. Many soakaways are wrapped in a fabric meant to stop soil from entering. But if the wrong fabric is used (or if it’s old), fine silt blinds the fabric—plastering it shut like paint on a screen. Water sits inside, unable to escape. 3. Soil Swelling and Biomat Growth This is the deep, biological twist. Over time, the soil around the soakaway develops a biomat —a slimy layer of anaerobic bacteria and decomposed organic matter. It forms where water constantly sits. This biomat is almost impermeable. It seals the native soil as effectively as clay. 4. The Clay Horizon Sometimes, the problem is deeper. Your soakaway was installed into sandy loam—great at first. But 1 meter down, there’s a hidden clay layer. Water percolates until it hits that clay, then just … stops. The soakaway fills, and the only way out is evaporation or slow sideways wicking. That can take weeks. 5. Compaction from Above Maybe you parked a car over the soakaway. Maybe the ground settled. Heavy loads crush the soil structure, closing the macropores that water needs. The soakaway becomes a sealed chamber. Part 4: The Crisis Point (Standing Water for Weeks) Now it’s after a spring rain. The soakaway is full—not just for a day, but for a month. The water table may have risen seasonally, or the outlet is blocked.
