Waterproofing Underground Structures: Innovative and Durable Solutions.

Water is a major factor in the deterioration of concrete. Seepage can lead to corrosion of reinforcement, crack formation and deterioration of the structure.

‍

The main problems associated with waterproofing underground structures include:

‍

• Hydrostatic pressure: the buoyancy of water can cause seepage through pores, joints and cracks.
• Freeze-thaw cycles: water penetrated into the pores of concrete can expand with frost, causing structural damage.
• Chemical attacks: sulfates, chlorides and other aggressive agents in the soil can compromise the integrity of concrete.
• Structural movements: soil settlements and temperature changes can generate micro-cracks that promote the passage of water.

Several solutions can be adopted to make waterproof underground structures. Among the most advanced and effective areintegral waterproofing using crystallizing admixtures, which transform concrete into a self-contained waterproof barrier.

The use of crystallizing admixtures, such as Drymix and Drymix Ultra, allows waterproofing to be integrated directly into the concrete matrix.

‍

This technology is based on a chemical reaction that occurs on contact with water, generating insoluble crystals that occlude pores and micro-cracks up to 0.4 mm wide.

‍

Advantages of crystallizing technology:

‍
✅Permanent, self-healing waterproofing.
✅ Reduction in thecoefficient of concrete permeability.
✅ Increased resistance to aggressive chemicals.
✅ Elimination of external membranes prone to damage.
✅ Ease of application and reduced maintenance costs.

Drykos ' DRYBOXSYSTEM® System is an advanced solution that combines the use of crystallizing additives with strategic management of critical structure points, such as joints and plant crossings.

‍

System components:

‍

• Crystallizing admixtures (Drymix and Drymix Ultra) to waterproof concrete in bulk.
• Construction and expansion joint systems with hydro-expansive profiles and high-performance sealants.
• Protective coatings and waterproofing mortars for work on existing structures.

‍

Applications of Waterproof Underground Structures

Waterproofing with the DRYBOXSYSTEM® is ideal for numerous applications, including:

‍

• Foundations and retaining walls of residential and commercial buildings.
• Basement parking lots prone to seepage and moisture.
• Drinking water tanks and sewage treatment plants.
• Tunnels, tunnels, and transportation infrastructure.
