Overview
Savenergy moisture-control products form a technical system to treat rising damp, salt crystallization and mold in interior and exterior masonry. The range combines HUMIBLOCK, CAL PLASTER and MUFFASTEM to restore, protect and finish walls while preserving breathability and finishing dimensions.

HUMIBLOCK – dehumidifying skim coat for rising damp
HUMIBLOCK is a white, fiber‑reinforced, inorganic skim coat formulated for dehumidification, waterproofing and restoration of masonry (interior/exterior/retaining structures).

• Suitable for:
  • Capillary rising damp
  • Water infiltration and seepage
  • Hydrostatic pressure (positive and negative)
• Prevents mold and condensation
• Nanotechnological fillers to control salt behavior
• Calibrated evaporation rate to limit salt crystallization while maintaining breathability
• Reduced application thickness for renovation constraints

How HUMIBLOCK works
HUMIBLOCK manages moisture and salt phases in the masonry rather than acting as a simple barrier. Its formulation and controlled drying regulate evaporation, reduce pore pressure and stabilize salts to prevent destructive crystallization while keeping walls breathable.

• Effective on:
  • Rising capillary damp
  • Seepage and infiltration
  • Condensation‑prone areas

CAL PLASTER – breathable lime‑based finishing plaster
CAL PLASTER is a mineral lime finishing coat designed for long‑term durability and high breathability, suited to historic restoration and breathable building envelopes.

• Recommended for:
  • Historic buildings and architectural restoration
  • Projects requiring maximum breathability
  • Walls exposed to pollutants and UV
• Fine or medium grain; tintable
• Contains fungicidal/bactericidal additives and silane water repellents
• Nanotech fillers for improved performance and aesthetic durability

MUFFASTEM – anti‑mold treatment
MUFFASTEM is a high‑penetration liquid treatment (transparent or white) to eliminate visible fungal spores and prevent regrowth on interior and exterior surfaces.

• Water‑based formula with sodium hypochlorite
• Surfactants for deep substrate penetration
• Long‑lasting protection in humid environments

Technical specifications

• HUMIBLOCK: white, fiber‑reinforced, inorganic, odorless skim coat; nanotechnological fillers; calibrated evaporation to prevent salt crystallization; reduced application thickness; suitable for interior/exterior/underground masonry; addresses capillary rise, infiltration, hydrostatic pressure, condensation and mold prevention.
• CAL PLASTER: mineral lime finishing plaster; fine or medium grain; tintable; includes fungicidal and bactericidal agents; silane‑based water repellents and nanotech fillers; designed for high breathability and long aesthetic durability, ideal for restorations.
• MUFFASTEM: high‑penetration liquid anti‑mold treatment; transparent or white; water‑based with sodium hypochlorite; surfactants for deep penetration; suitable for interior and exterior use; provides durable mold prevention.

Applications

• Restoration of historic and residential buildings
• Basement and retaining walls
• Areas affected by capillary rise, seepage or condensation
• Renovations requiring preserved finishing dimensions and breathability

Guarantee and compliance
Savenergy supplies product data sheets and verifiable warranties; performance is based on salt crystallization control and is applicable to verified restoration cycles.

FAQ essentials

• HUMIBLOCK controls salt crystallization and manages moisture phases rather than acting solely as a chemical barrier.
• The cycle is compatible with breathable finishes and historic substrates.
• Complementary products CAL PLASTER and MUFFASTEM provide finishing and mold prevention within the same system.
