Calculadora de Membrana Impermeabilizante — ft, sq ft, cost
Como usar esta calculadora
Seleccione el tipo de superficie — muro de cimentacion (perimetro × profundidad), losa/piso, terraza/balcon, o ingrese area personalizada. Elija el tipo de membrana: liquida aplicada, lamina (autoadhesiva), placa de drenaje, o membrana con protuberancias. Los resultados se actualizan con cantidad de membrana, primer opcional, cinta para juntas y costo.
Liquida aplicada — cobertura en ft2/gal a 60 mil de espesor de pelicula seca.
Membrana laminar — rollos autoadhesivos de 36″ de ancho, traslape de 6″.
Placa de drenaje — hojas de 4'x50' (200 ft2).
Membrana con protuberancias — rollos de 4'x50' (200 ft2).

How to Calculate Waterproofing Membrane
Esta calculadora estima membrane quantity for foundation muros, slabs, decks, and custom areas. Choose from liquid applied (coverage ~25 ft²/gal at 60 mil DFT), peel-and-stick sheet membrane (36″ wide rolls with 6″ overlap), drain board, or dimple mat (4′×50′ sheets).
Formulas
Liquid: gallons = area / cobertura por gallon. Sheet: rolls = area / (roll width × roll length × effective coverage factor). Drain board / dimple mat: sheets = area / 200 ft². Seam tape: linear feet = number of seams × seam length. Primer: gallons = area / 300.
Application Standards
ASTM D6153 for self-adhered sheet membranes. ICC-ES evaluation reports for liquid membranes. Minimo 60 mil DFT (dry film thickness) for below-grade waterproofing. Two coats recommended for liquid applied systems.
Preguntas frecuentes
Do I need primer? Most peel-and-stick and liquid membranes require primer on concrete surfaces. Check manufacturer specs. Drain board vs dimple mat? Both protect the membrane and facilitate drainage. Drain boards add R-value; dimple mats are more economical.
