Tectonic Specifications & Architectural Engineering
Bioclimatic Engineering Strategy
Naturally immune to subterranean termites and fungal rot without toxic chemical treatment. Ideal for high-humidity equatorial rainforest zones where steel corrodes and softwoods disintegrate.
Mortar Formulation & Stabilization Mix
Traditional pegged mortise & tenon carpentry with galvanized stainless connectors
Curing, Quality Control & Erosion Protection
