WHICH WATERPROOFING SOLUTIONS WORK BEST FOR EACH AREA

Each area in a building has a different mechanism of water infiltration. Therefore, customized waterproofing consulting is essential to select the appropriate materials and methods. Incorrect applications not only cause re-leaks but also increase future repair costs.

Exterior walls and roof joints are prone to water infiltration

Exterior walls are exposed to sun, rain, strong wind, and outdoor humidity. Without proper treatment, water can seep through the paint layer, causing peeling, discoloration, or mold growth.
SKSumo typically recommends:

• Sika Flex or polyurethane sealant: for cracks at wall-roof joints, expansion joints, and wall bases
• Silicone-based waterproof paint (e.g., Kova CT11A, Sika RainTite): adheres well on vertical surfaces, highly resistant to rain
• Bitumen self-adhesive membranes: ideal for base wall sections or joint areas

Junctions and small cracks should be sealed early with elastic materials to prevent capillary seepage.

Flat roofs, terraces, and balconies prone to rainwater accumulation

Horizontal surfaces like roofs and terraces tend to collect rainwater. Without proper drainage, this leads to seepage into lower floors.

SKSumo uses a dual technical approach:

1. Proper slope construction to ensure fast drainage
2. Use of highly elastic waterproof materials:

• Liquid PU (e.g., Sikaproof Membrane, Sika Bit 2K): self-leveling, fills cracks, flexible
• Torch-on or self-adhesive bitumen membranes: strong adhesion, suitable for large areas
• PU foam spray on metal roofs: excellent for west-facing roofs, combines waterproofing with insulation when paired with plaster ceilings

For metal roofs, this solution enhances energy efficiency in Central Vietnam's hot climate.

Basements and foundations subject to high groundwater pressure

Basements and foundations are often under groundwater pressure, especially after heavy rain or high tides. Specialized negative-side waterproofing is required.

SKSumo uses:

• Sika®-1 or SikaTop Seal systems: effective for both new and retrofit basements
• Intoc or Penetron: penetrate concrete and form water-blocking crystals
• Multi-layer self-adhesive or torch-on membranes: protect external foundation surfaces
• Sika Swell sealants or swelling tapes: seal pipe collars, expansion joints, and construction joints – areas prone to leakage

The construction process must also carefully handle cold joints, pipe penetrations, and wall-floor transitions for lasting effectiveness.

WHAT WATERPROOFING MATERIALS TO USE FOR EACH COMPONENT

No single waterproofing material works for all areas. Each building zone has different structural, humidity, and temperature conditions. Effective waterproofing consulting requires tailored material selection for each area.

Materials for roofs and terraces

Roofs and terraces face extreme sun, rain, and thermal expansion, which can cause cracking if poorly constructed. SKSumo Đà Nẵng Waterproofing Company recommends:

• Liquid PU: high elasticity, fills cracks, ideal for concrete and metal roofs
• Sika RainTite or SikaBit Pro: specialized UV-resistant, weather-durable products with 10–15 years lifespan
• Torch-on membranes: effective for large concrete roof decks
• Self-adhesive bitumen sheets: cost-effective for residential buildings if surface is well-prepped

Tip: For new builds or quick turnarounds, SikaBit® or liquid PU offers durability and aesthetic value.

Materials for bathrooms, kitchens, and upper floors

These areas involve frequent water exposure and dense plumbing, making proper waterproofing essential to avoid leaks below. Recommended:

• Sikatop Seal 107 or Kova CT11A: polymer-cement coating – adheres well, ideal for tight spaces
• Pipe collar seals: prevent leaks around drainage points
• Cold joint sealants: seal transitions at wall-floor joints or wall bases

Tip: For retrofits, Sikatop Seal 107 is widely used with excellent adhesion on old flooring.

Materials for basements, foundations, and below-grade zones

These require reverse waterproofing due to long-term groundwater pressure.

SKSumo often implements:

• Sika®-1 or Penetron: deep-penetrating crystalline products
• Multi-layer self-adhesive membranes: dual waterproofing and light insulation
• Sika Swell sealants or tapes: expand upon contact with water to block hidden leaks

Tip: For areas with large cold joints, combining Sika Swell + Penetron or Sika®-1 enhances protection and prevents future re-leaks.

SHOULD YOU SWITCH TO MODERN WATERPROOFING TECHNOLOGIES

Yes. Modern methods extend building lifespan, reduce maintenance costs, and are more suited to complex urban structures.

Comparison: Traditional vs. Modern Waterproofing

Benefits of modern tech

• Reduce maintenance costs by at least 30% over 5 years
• Compatible with soundproofing and insulation
• Faster application, less labor-dependent

WHAT SOUNDPROOFING SOLUTION FITS EACH TYPE OF NOISE

Not all noise is the same. Each sound type transmits differently and needs a specific soundproofing method for optimal results.

Airborne noise (traffic, voices, TV)

Enters through walls, doors, and gaps. Solutions:

• Double-layer gypsum walls + mineral wool insulation
• Solid wood doors + rubber seals
• Tempered or double-glazed glass for roadside homes

Structure-borne noise (footsteps, washers, ceiling systems)

Spreads through floors and walls. Solutions:

• EPDM rubber or anti-vibration foam underflooring
• Floating floors or suspended plaster ceilings
• XPS foam for vibration dampening

Reverberation and echo control (in studios, halls)

Hard-surface spaces create unwanted echoes. Solutions:

• Acoustic foam, perforated wood, sound-absorbing panels
• Soft, porous interior design
• Acoustic wall panels or ceiling diffusers

HOW TO EFFECTIVELY INSULATE HOT REGIONS

Effective insulation depends on local climate, sun orientation, roof type, and usage. Proper material, placement, and method can reduce indoor temps by 10–20°C and significantly cut power bills.

Insulation for metal roofs and concrete ceilings

• Metal roofs: 30mm PU foam spray + internal plaster ceiling
• Concrete slabs: reflective aluminum film + XPS or EPS foam
• West-facing homes: combine sunshade, heat reflection, and ventilation

Insulation for west-facing walls

• External/internal XPS panels
• Thermal breeze blocks – dual purpose aesthetics and ventilation
• Heat-reflective paint

Industrial-grade insulation for factories/cold storage

• EPS/PU Panels or mineral wool
• Airflow-based thermal zoning
• Insulated doors + thermal curtains

HOW TO MINIMIZE COST FOR SOUND & HEAT INSULATION

Soundproofing and insulation don’t have to be expensive. With expert consultation, costs can be reduced up to 25% while ensuring effectiveness.

Save cost with smart multilayer design

Instead of premium single layers, split functions:

• Heat reflection: double-sided PE foil or aluminum membrane
• Thermal barrier: XPS foam, PU foam, or mineral wool

This approach delivers similar performance at 20–30% lower cost, suitable for homes and industry.

Designing for solar orientation and airflow

Savings come not only from materials but also strategic layout:

• West or SW homes: thick insulation with reflective PU foam roofing
• Add roof fans or natural vents to reduce heat load
• Plan air circulation paths to reduce A/C use

Case studies:

• Metal-roof homes: PU foam spray + plaster ceiling = 18–20°C roof temp drop
• Garment factory: PU panels + door films = 30% cooling energy savings

SKSumo has applied these successfully across Central Vietnam.

WHY EARLY-STAGE TECHNICAL CONSULTING IS CRUCIAL

Early consulting on waterproofing, soundproofing, and insulation prevents later repair costs, extends building life, and boosts performance.

Total solution = long-term savings

Early planning allows:

• No redundant work
• Fewer technical errors (cracks, leaks, vibrations)
• Efficient cooling from proper insulation

SKSumo integrates consulting from the blueprint phase.

Total design = material and technique synergy

A master plan enables:

• Insulation materials also offer waterproofing
• Soundproofing + insulation installed with plaster ceilings
• Unified materials from the same supplier → cheaper and easier warranty

Avoid costly overlap and rework

Mistakes often occur from poor sequencing:

• Waterproofing after insulation → less effective
• Soundproofing after installation → damages ceiling
• Unsealed cold joints → costly repairs in months

Early consulting ensures correct sequencing and materials – saving 20–30% of budget.
