What Biodry does

Biodry is the commercial brand of Wall & Wall Sagl, a Swiss private limited company founded in 2009 and headquartered in Chiasso. The company develops and markets a hardware device that addresses rising damp in buildings using proprietary counterphase technology. The device detects electrical disturbance waves in walls and soil that promote capillary rise of groundwater, then emits opposite-phase signals to neutralize those disturbances and reverse the molecular flow of water, allowing walls to dry naturally without excavation, chemicals, or removal of plaster.

The product portfolio consists of two SKUs: the core Biodry Device (24cm x 11cm x 6cm, 650g, installed in 4-8 hours) and an optional Monitoring Probe system providing 24/7 remote humidity and temperature tracking with monthly reports. Biodry operates a hybrid distribution model combining a franchise network that grants territorial exclusivity to entrepreneurs, a Junior Consultant referral program targeting architects, surveyors, engineers, painters, and restorers who earn commissions, and direct installation by certified technical consultants. Revenue is generated through one-time hardware sales, optional monitoring probe sales, franchise/license fees, and referral commissions. Pricing is quote-based, varies with property size and complexity, and is backed by a 70% refund guarantee if results are not achieved within three years.

Biodry holds CE and TUV certifications, documents results under UNI standards, and has registered the Biodry® trademark. The company is led by General Manager Daniele Tarabini and operates through offices in Switzerland, the United Kingdom, and Italy, with end installations documented across 30+ countries in Europe and Latin America. Customer segments include historic and heritage buildings, private residential, public entities, ecclesiastical institutions, hospitality and tourism, and construction/restoration professionals, with a notable concentration of documented case studies in Italian religious and cultural buildings.

Revenue model

1. Biodry Device Sales: Primary revenue stream from the sale of the Biodry device, a hardware product that permanently solves rising damp. The device is sold directly through franchisees and certified consultants with installation included or offered as a separate service. Pricing varies based on property size and complexity.
2. Monitoring Probes and Remote Control: Optional monitoring probes sold alongside the device for continuous humidity and temperature monitoring. Provides real-time data access and monthly reports for ongoing moisture management.
3. Consultant Referral Commissions: Junior consultants (architects, surveyors, engineers, restorers) earn commissions for referring clients to Biodry. This creates a network revenue stream without direct product sales from the company to end customers.
4. Franchise Fees: Entrepreneurs pay for franchise rights to operate in exclusive territories, receiving training, marketing tools, technical support, and access to the Biodry brand and technology.

Core offering

Biodry manufactures and sells a compact electronic device that uses proprietary counterphase signal technology to detect and neutralize electrical disturbance waves in walls, reversing the capillary rise of water and permanently eliminating rising damp in buildings without excavation, chemicals, or structural changes. The offering is complemented by optional remote monitoring probes that continuously measure humidity and temperature, and is delivered to customers via a global network of franchisees and certified technical consultants.

Product overview

Biodry is a physical device-based solution for treating rising damp in buildings, consisting of two main products: the Biodry Device and Monitoring Probes. The Biodry Device is the core product that uses counterphase technology to neutralize electrical disturbances causing water to rise through wall capillaries. The Monitoring Probes serve as an add-on module for continuous humidity and temperature monitoring, enabling real-time tracking of the drying process. Both products work together to provide a comprehensive solution for eliminating rising damp without invasive intervention.

Products and services

• Biodry Device The Biodry Device is the core electronic hardware product that uses proprietary counterphase technology to detect electrical disturbance waves in walls and soil that promote capillary rise of water, then generates opposite-phase signals that neutralize these disturbances and reverse the flow of water molecules, allowing walls to dry naturally. The compact unit (24cm height, 11cm width, 6cm depth, 650g weight) installs without excavation, structural changes, or removal of existing plaster in 4-8 hours, and is sold with a 70% refund guarantee if expected results are not achieved within three years. It is intended for property owners, heritage building custodians, religious institutions, and public entities facing rising damp problems.

Direct peers

• Murprotec: Murprotec is a European specialist in rising damp and humidity treatment with a direct-to-homeowner and franchise-led model across multiple countries. Like Biodry, it addresses capillary rise in existing buildings through a proprietary technical approach and operates across Southern and Western Europe, making it the closest geographic and product peer.
• Wykamol Group: Wykamol manufactures and distributes damp-proofing and waterproofing systems for the UK and international markets, including rising damp injections and structural waterproofing. It is a close competitor to Biodry's traditional-moisture-method positioning and shares the building-trade channel model.
• Peter Cox: Peter Cox is a long-standing UK property preservation company specializing in damp proofing, waterproofing, and timber treatment for both residential and heritage buildings. Its service-led approach to rising damp is conceptually aligned with Biodry, though it relies primarily on conventional injected and membrane methods rather than counterphase electronics.
• Safeguard Europe: Safeguard Europe supplies damp-proofing products and systems (e.g., Dryzone DPC injection creams, water management membranes) to contractors and resellers across Europe. It competes directly with Biodry in the rising damp space via chemical-injection methods, targeting similar trade and homeowner segments through a distribution model.
• Remmers (Remmers Baustofftechnik): Remmers is a German specialist in wood and building protection, including damp-proofing, basement waterproofing, and historic monument restoration systems sold across Europe. It addresses rising damp and masonry moisture through chemical/surface methods for a comparable residential and heritage customer base.

Broad incumbents

• Sika: Sika is a Swiss-headquartered construction chemicals and industrial coatings group offering waterproofing, concrete repair, and sealing systems used in both new build and heritage retrofits. Its waterproofing and repair ranges overlap functionally with Biodry's heritage and building-moisture use cases through traditional chemical and membrane approaches.
• Mapei: Mapei is a global construction chemicals manufacturer with an extensive restoration and building-repair product range addressing masonry moisture, structural strengthening, and historic-building conservation. It competes in the same specification environment for rising damp and heritage restoration projects, but as part of a far broader materials portfolio.
• Kerakoll Group: Kerakoll is an Italian building products group with a strong heritage in green-building materials, restoration mortars, and structural repair systems. Its Biocalce and historical-renovation lines target the same architectural-heritage customer base that Biodry serves, although via conventional materials rather than electronic devices.
• Rentokil Property Care (Rentokil Initial): Rentokil Initial is a global property services group whose Property Care division offers damp proofing, timber treatment, and waterproofing alongside pest control and hygiene. It overlaps with Biodry on rising damp treatment for residential and commercial customers, especially in the UK, but serves that need as one of many services at much larger scale.

Regional players

• Danosa: Danosa is a Spanish building waterproofing and insulation specialist with growing international presence in Latin America, offering membranes, drainage, and damp-proofing systems. It targets the same moisture-in-buildings problem Biodry addresses in selected overlapping geographies, but via conventional physical waterproofing rather than electronic counterphase technology.
