The Smart Alternative to Sandbags

Comparison of Water Barriers & Hoses

Both flood protection systems are **100% eco-friendly and free of harmful substances** and are handcrafted in our factory. They are designed with different core fillings to ensure maximum efficiency in an emergency.

Loidhold Water Protection Cushion with Active Fiber Core
Water Protection Hose, Gray, Fiber-Active Core
🔄 Reusable Unlimited Times

Dimensionally Stable Fiber-Active Core (FTF)

Mechanical sponge effect: Absorbs water and spilled liquids in a flash—in a matter of seconds—thanks to its highly porous capillary structure.

♻️
Reusability & Handling:

Instant and unlimited! After use, simply squeeze it out by hand or spin it dry. The system retains its shape permanently and can be reactivated an infinite number of times.

🌱
Environmental Sustainability:

Sustainable, durable synthetic fabric without chemical additives. Conserves resources through decades of durability and handcrafted production free of harmful substances.

🎯
Ideal application:

Ideal for indoor use, basements, laundry rooms, water seeping around doors and windows, and for quick drying. Also absorbs oils and chemicals.

Super-Absorbent Water Barriers
SuperAbsorber Water Protection Hoses
🧱 Seasonal, Can Be Reactivated Multiple Times

Superabsorbent Granules (SAP)

Gel-Based Solid Barrier: The integrated polymer granules absorb water, swell significantly, and form an extremely heavy, impenetrable barrier.

🛡️
Reusability & Handling:

Reusable! Remains stable throughout the entire flood period. Allow to dry completely in the sun after use: the granules will return to their original state. Can be stored just like sandbags!

🌍
Environmental Sustainability:

An environmentally neutral, non-toxic absorbent material. Unlike conventional sandbags, it does not create piles of contaminated sand and protects waterways and soil.

🚧
Ideal applications:

The most advanced sandbag alternative for outdoor use. Ideal for placing in front of factory gates, garage entrances, and front doors to block rushing floodwaters.

🔬 Technical Cross-Section & Material Drawing

Schematic diagram of the barrier layers in a fully saturated state

Construction: Fiber-Active Core
CAPILLARY CORE
100% toxin-free PP coating
Thermal Hollow-Fiber Matrix (Dimensionally Stable)
Mechanically bound water molecules

Principle: Purely mechanical absorption. The fabric does not expand chemically, but rather utilizes its maximum void volume.

Construction: Superabsorbent granules
GEL BLOCK
Extremely tear-resistant outer protective fabric
Cross-linked sodium polyacrylate polymers
Massive Crystallization Barrier

Phenomenon: Osmotic swelling principle. The dry polymers convert incoming water into a solid gel, increasing their own weight many times over.

Production for private homes

In cooperation with the state of Lower Austria, Loidhold GmbH has manufactured various flood protection systems for private homes.

120,000 € water damage - prevented with € 1,550 in precautions

When groundwater penetrates the cellar, it gets expensive

In September 2024, a single-family home suffered severe water damage due to seepage and flooding. Within a short time, water flowed unchecked into the basement.
With an investment of just €1,550, preventive measures were subsequently taken—and further damage was reliably prevented.

Installation situation / protected condition

3,500 € investment - a six-figure loss prevented

They are made to measure, adapted to the structural situation and deployed quickly in an emergency.

This building was equipped with a custom-configured barrier beam system two years ago.
During last year’s extreme flooding, the property remained completely protected—while the surrounding area suffered massive damage.
This preventive measure , which cost approximately €3,500, prevented six-figure property damage.
Reality shows that severe weather events are becoming more frequent, more intense, and more unpredictable. Taking preventive measures is no longer an option—it’s a necessary decision.

Moisture after water damage - building drying & dehumidification

If walls, floors or the basement remain damp after a flood or water damage, mold growth, odor problems and costly consequential damage can occur.

In such cases, we offer professional construction dehumidifiers and air dehumidifiers for the targeted drying of living spaces, basements, and buildings.
These units facilitate fast and controlled construction drying, ensuring that affected areas become usable and habitable again.

Wir haben ein Dammbalkensystem für unser Garagentor bestellt und sind wirklich begeistert wie gut die Dichtwirkung davon ist. Das haben wir gemeinsam bei uns an einem Vormittag aufgebaut, also die Selbstmontage mit der Anleitung ist kein Problem. Bis jetzt alles ausgehalten. Michael war auch am Telefon super freundlich und hat uns telefonisch nochmal alles abgesichert.
