Our specialized team provides comprehensive moisture control solutions designed specifically for Singapore's humid tropical environment. We work with proven materials and established techniques to protect your below-ground spaces from water intrusion, ensuring long-lasting results for residential and commercial properties.
Installation of high-grade waterproof membranes on basement walls and floors. We use multi-layer polyethylene or PVC sheets with sealed joints, creating a continuous barrier against groundwater penetration. The membrane is anchored securely to concrete surfaces using mechanical fasteners and specialized adhesives. This system includes drainage channels at the base to redirect water away from the structure, preventing hydrostatic pressure buildup.
Application of polymer-modified cement-based waterproof coatings on interior and exterior basement surfaces. The coating penetrates concrete pores and forms crystalline structures that block water passage while allowing vapor transmission. We apply two coats with minimum 1.5mm thickness, reinforced with fiberglass mesh at joints and corners. Suitable for both positive and negative side water pressure situations in tropical conditions.
Application of cold-applied liquid rubber or acrylic polymer membranes that cure to form seamless, elastic barriers. The liquid formula adapts to surface irregularities and forms a monolithic coating without joints. We apply 3-4 coats achieving 2mm minimum dry film thickness, with reinforcement fabric embedded in wet layers. This method works effectively on complex geometries and provides excellent adhesion to concrete and masonry substrates.
Installation of perimeter drainage systems around basement foundations to manage groundwater levels. We excavate trenches, install perforated pipes surrounded by gravel, and connect to sump pits or storm drains. The system includes filter fabric to prevent soil clogging and ensures continuous water evacuation. French drains are positioned below floor level to intercept water before it reaches the structure, reducing hydrostatic pressure on walls and slabs.
Application of penetrating crystalline compounds that react with moisture and concrete minerals to form insoluble crystals within capillary pores. The treatment is applied as a slurry coating or added to concrete mix during construction. Crystals grow throughout the concrete matrix, self-sealing hairline cracks up to 0.4mm. This permanent solution works under both positive and negative water pressure, making it ideal for below-grade structures in high water table areas.
Injection of polyurethane or epoxy resins into concrete cracks to create watertight seals. We use low-pressure injection through ports installed along crack paths, ensuring complete resin penetration. Polyurethane foams expand upon contact with moisture, filling voids and stopping active leaks. Epoxy creates rigid structural bonds for dormant cracks. This targeted repair method addresses specific failure points without requiring extensive excavation or surface preparation of entire walls.
Installation of automatic sump pump systems to remove accumulated water from basement sumps. We install submersible pumps with float switches, backup power systems, and discharge piping that directs water away from the foundation. The sump pit is properly sized and sealed, with check valves preventing backflow. Regular capacity pumps handle 40-50 liters per minute, while high-capacity units manage heavy rainfall events common in tropical climates.
Installation of multi-component tanking systems combining render coats, waterproof slurries, and protective layers. We prepare surfaces by removing loose material, apply bonding agents, then build up waterproof layers to specified thickness. The system includes sand-cement renders, polymer-modified waterproof coatings, and protective screeds. This traditional method creates robust barriers suitable for basements subject to hydrostatic pressure from surrounding soil and groundwater in saturated conditions.
Installation of mechanical dehumidification units to control basement humidity levels and prevent condensation. We size units based on space volume and moisture load, install drainage connections, and integrate controls with existing HVAC systems. Commercial-grade dehumidifiers maintain 50-60% relative humidity, preventing mold growth and material deterioration. This active moisture control complements waterproofing barriers by managing interior vapor and seasonal humidity fluctuations typical in tropical environments.
Installation of electro-osmotic systems that use low-voltage electrical fields to repel moisture from masonry walls. Titanium anodes are embedded in walls, connected to control units that generate small electrical currents. The system reverses capillary action, forcing moisture back toward the exterior. Particularly effective for rising damp in older basement walls where external waterproofing is impractical. The method requires no excavation and operates continuously with minimal power consumption under 50 watts.
Comprehensive evaluation of basement moisture conditions using calibrated meters, thermal imaging, and visual inspection. We measure concrete moisture content, identify water entry points, assess drainage adequacy, and document existing damage. The survey includes soil permeability testing, water table level estimation, and structural crack mapping. Our detailed report specifies moisture sources, recommends appropriate solutions, and provides cost estimates for remediation work tailored to your specific site conditions and requirements.
Application of coal tar or asphalt-based bituminous coatings on exterior basement walls below grade. We apply two coats achieving 3mm minimum thickness, creating a flexible, waterproof barrier resistant to soil chemicals and root penetration. The coating is reinforced with fiberglass mesh at vulnerable areas and protected with drainage boards before backfilling. This economical solution provides reliable protection against groundwater intrusion in stable soil conditions with moderate hydrostatic pressure.
Installation of dimpled plastic membranes that create air gaps between walls and interior finishes, channeling water to drainage points. The studded sheets are mechanically fixed to walls, with water flowing down the cavity to perimeter channels connected to sump systems. This Type C waterproofing manages water rather than resisting it, making it suitable for situations with high water pressure or when external waterproofing is impossible. The cavity allows wall inspection and maintains dry interior surfaces.
Installation of closed-cell foam insulation boards over waterproof membranes to prevent condensation and improve energy efficiency. We use extruded polystyrene or polyisocyanurate boards with R-values appropriate for tropical climates, mechanically fastened or adhered to walls. The insulation reduces temperature differentials that cause condensation on cool basement surfaces. Vapor barriers are positioned correctly to prevent moisture accumulation within wall assemblies, ensuring long-term performance in humid conditions.
Injection of specialized grouts into soil or concrete to create impermeable barriers around basement perimeters. We drill injection holes at strategic locations and pump polyurethane, silicate, or acrylic grouts under controlled pressure. The grout permeates soil voids or concrete cracks, expanding and solidifying to form continuous waterproof zones. This method is effective for stopping groundwater flow in permeable soils or sealing construction joints and honeycomb concrete in existing structures without extensive excavation.
Annual inspection of existing waterproofing systems to verify continued effectiveness and identify potential issues before they cause damage. We check membrane integrity, drainage system function, sump pump operation, and dehumidifier performance. Inspections include moisture meter readings, visual examination of walls and floors for new cracks or efflorescence, and testing of backup systems. Our service report documents findings, recommends preventive maintenance, and estimates costs for any necessary repairs to maintain warranty coverage.
