muro Waterproofing Slurry HS - High Sulfate Resistant Dense Seal (25kg)

muro proof Dichtungsschlämme HS is a premium cement-based waterproofing slurry engineered for creating impermeable barriers against pressure water and moisture in demanding wet environments. This highly sulfate-resistant mortar produces an extremely dense barrier suitable for swimming pools, wet rooms, basements, underground structures, and water-retaining applications where conventional waterproofing is insufficient.

Key Features

• Extremely Dense Structure: Specialized aggregates and binders create impermeable mortar barrier
• High Sulfate Resistant (HS): Resistant to aggressive water and sulfate-rich environments
• Pressure Water Protection: Effective waterproofing against hydrostatic pressure and continuous moisture
• Excellent Adhesion: Strong bond to mineral substrates including concrete, brick, and stone
• Thin Application: Creates effective waterproof seal even at minimal application thickness
• Salt Encapsulation: When combined with muro sil, encapsulates damaging salts for long-term durability
• Physiologically Safe: Non-toxic when cured—safe for potable water tanks and food-contact areas
• European Standard: Complies with DIN EN 998-1 CS IV (MG III) W 2 classification

Applications

• Waterproofing for wet rooms, bathrooms, and shower areas
• Swimming pools and water tank sealing
• Basement and cellar waterproofing and damp-proofing
• Underground garage and parking structure sealing
• Tunnel and shaft waterproofing
• Retaining walls and foundation sealing
• Septic tanks and wastewater treatment installations
• Industrial water-retaining structures
• Horizontal moisture barriers in walls and foundations
• Concrete repair and protective coating in aggressive water environments

Coverage: Typically 1.5-2 m² per 25kg bag depending on application thickness and surface porosity (standard 5-10mm thickness)
Water Resistance: Provides effective barrier against pressure water and hydrostatic conditions
Sulfate Resistance: High resistance to sulfate-rich water and aggressive groundwater
Adhesion: Strong mechanical bond to concrete, brick, stone, and cementitious substrates
Application Temperature: Minimum 5°C; optimal 15-25°C; avoid application in freezing conditions
Curing Time: Initial set 24-48 hours; full cure 7-14 days depending on temperature and humidity
Permeability: Extremely low permeability provides long-term water protection
Storage: Store in cool, dry conditions; shelf life 12 months in original sealed packaging

Substrate Preparation

• Clean substrate thoroughly - remove dust, algae, loose material, and contaminants
• All surfaces must be solid, stable, and well-adhered
• Remove any flaking concrete or damaged mortar joints
• Dampen substrate (but not saturated) before application for optimal adhesion
• Repair any cracks or structural issues before waterproofing application
• Ensure all construction joints are properly prepared and sealed
• For maximum durability, use in combination with muro sil for depth penetration

Application Instructions

1. Mix to Slurry Consistency: Add water to 25kg bag according to desired application thickness (typically 5-10 liters for normal consistency). Mix thoroughly with mechanical mixer until uniform, creamy slurry is achieved with no lumps.
2. Prepare Substrate: Clean and dampen substrate surface. Remove dust and loose material. Ensure substrate is sound and structurally stable.
3. Apply Waterproofing Slurry: Apply mixed slurry using brush, trowel, or spray equipment depending on surface area and access. Build up protective barrier with consistent thickness across entire application area.
4. Work Multiple Passes if Needed: For maximum waterproofing on critical areas (seams, joints, corners), apply in 2-3 passes. Allow initial set between applications (typically 24-48 hours).
5. Cure Fully: Allow minimum 7-14 days full cure before exposing to water or hydrostatic pressure. Protect from rain and water spray during curing period.
6. Optional Secondary Treatment: For enhanced durability in aggressive water environments, apply muro sil penetrating sealant over cured slurry to encapsulate salts and extend lifespan.

Safety & Storage

• Contains Portland cement - skin and eye irritant. Avoid prolonged contact with skin.
• In case of skin contact, wash immediately with clean water.
• In case of eye contact, rinse thoroughly with water for at least 15 minutes and seek medical attention if irritation persists.
• Wear appropriate PPE: gloves, eye protection, dust mask, and protective clothing during mixing and application.
• Use in well-ventilated areas.
• Once cured, product is physiologically safe and non-toxic. Safe for use in potable water tanks when properly applied and cured.
• Store in cool, dry conditions (15-25°C) in original sealed packaging.
• Protect from moisture and rain during storage.
• Shelf life: 12 months in sealed original containers.
• Keep away from children and pets.
• Refer to Safety Data Sheet for complete handling and disposal information.

Why Choose muro proof Waterproofing Slurry?

muro proof represents the professional choice for demanding waterproofing applications where standard methods are insufficient. Manufactured to European DIN EN 998-1 standards, this dense-seal mortar delivers reliable, long-lasting protection in the harshest wet environments. From luxury wet rooms and swimming pools to underground parking structures and industrial water tanks, muro proof provides the durability and performance specification-conscious contractors demand. The high sulfate resistance ensures protection even in aggressive groundwater conditions where ordinary mortars would fail.
