Caviti

Permanent recycled plastic formwork for ventilated slabs, crawl spaces and eco-friendly ground floors.

Caviti

Description

Recycled polypropylene lost formwork system that forms a ventilated crawl space under slabs. The modular pieces assemble to create a continuous cavity that drains moisture and removes gases from the subsoil such as radon, improving healthiness. It also lightens structures and reduces concrete volume, providing thermal and acoustic insulation. The elements are manufactured from recycled plastic and are recyclable at the end of their service life.

Data source

Sistema de encofrado perdido / cámara ventilada bajo solera, polipropileno 100% reciclado. EPD verificada (The International EPD System S-P-05325, EN 15804+A2; 18-02-2022→17-02-2027): unidad declarada 1 KG del sistema (el impacto es proporcional al peso, no al m²). GWP-total A1–A3 = 0,377 kg CO₂eq/kg (fósil 0,362). Por pieza: peso × 0,377 (p.ej. C20 ≈1,77 kg → ~0,67 kg CO₂/pieza, cálculo derivado). ✅ Corregido: el campo tenía 2021, que era el AÑO de la EPD; no se traslada a GWP_m2/m3 porque la unidad real es por kg.
