Sanitation Fact Sheet: Stabilized Soil Lining
The fact sheet is CAWST's "Stabilized Soil Lining" resource — it introduces the Stabilized Soil Lining (SSL) technique for lining pit latrines. It's a sanitation method that reinforces the walls of a pit latrine using a soil-cement mixture (roughly 1 part cement to 10 parts soil) packed against a reusable circular mold, built up in layers as the mold is raised. It's positioned as a lower-cost alternative to other pit-lining options like precast concrete rings, blocks, and oil drums — the sheet includes a cost comparison showing it around $2 USD per foot versus $8–70+ USD for the alternatives.
Importantly, the technique is still under investigation: the fact sheet carries a disclaimer noting that the SSL method is in the testing phase, and further testing is needed to fully understand its structural limitations before it's applied at scale.
