Professional Basement Waterproofing & Masonry Drying

Professional Basement Waterproofing & Masonry Drying

Damp basement walls reduce living comfort and endanger the building structure of your home. We offer highly effective systems for internal sealing, retroactive horizontal barriers, and crack injection.

✓ Non-Destructive Moisture Measurement
✓ Wall Surface Waterproofing
✓ Injection Technology

Retroactive Horizontal Barrier

Permanently stop rising damp in masonry – without excavation.

With our pressureless injection method, we stop rising dampness directly in the masonry – clean, dust-free, and absolutely reliable. The hydrophobizing silane cream forms a permanent barrier against capillary water transport.

  • ✓ 100% dust-free and clean execution from inside
  • ✓ No digging up of gardens, terraces, or outdoor areas
  • ✓ WTA-certified silane injection for permanently dry masonry

Before and After: Basement Entrance Restoration

On this property, the damp side walls and damaged steps of an exterior basement entrance were restored, sealed with a mineral waterproofing slurry, and finished with a slip-resistant coating.

After After
Before Before

Waterproofing Earth-Contacting Walls

The side walls were pretreated and sealed with mineral waterproofing to protect against lateral moisture ingress.

Step Restoration & Surface Coating

Removal of damaged tiles, crack repair on the concrete substrate, and application of a slip-resistant surface coating.

Wall Plaster & Protective Capping

Application of breathable restoration plaster against salt efflorescence and installation of weather-resistant coping on the wall tops.

Basement Waterproofing Inside vs. Outside: The Objective Comparison

Whether interior or exterior waterproofing is best depends on structural conditions, site accessibility, and your individual priorities. Both methods offer distinct strengths and specific boundaries.

Criterion

Interior Waterproofing

Protection from inside the room No excavation required

Exterior Waterproofing

Full protection from the outside Protects entire wall
🏡 Excavation & Grounds

No excavation required: Garden, terrace, garage, paving, and landscaping remain completely intact.

Extensive earthworks down to foundation level: Outdoor facilities must be dismantled and restored afterwards.

Keeps basement living and storage spaces dry and usable. The outer wall structure remains in a moist state within the soil. The degradation process of the masonry is stopped.

Keeps the entire masonry wall dry. Moisture is stopped before entering, allowing the wall structure to dry completely.

Universally applicable: Feasible without issues even for terraced homes, property boundaries, extensions, or covered walls.

Only viable when exterior walls are fully accessible all around and sufficient clearance for excavators and slopes exists.

Year-round and weather-independent: Work can be executed swiftly within a few days even in winter or during heavy rain.

Heavily weather-dependent: Requires dry conditions and frost-free temperatures for digging and multi-layer seal curing.

Substantially more economical and predictable: Major savings since no costly excavators, soil disposal, or landscaping repairs are needed.

Higher total investment: Excavation, soil transport, pit shoring, and subsequent garden restoration increase total expenditure.

Densely built plots, established gardens/terraces, terraced houses, swift remediation, or constrained renovation budgets.

Detached buildings with open access, when landscaping is scheduled for redesign anyway, or when exterior perimeter insulation is desired.

Which solution fits your property best?

Neither method is universally 'better'—the optimal choice always depends on your specific building, budget, and structural conditions. During our free on-site analysis, our WTA-certified building expert objectively evaluates your basement and recommends the most reliable, cost-effective procedure.
