ROOF, SLAB & WALL WATERPROOFING BARRIER

HYDRO SEAL HF

UNIVERSAL ACRYLIC
WATERPROOF COATING

HydroSeal HF is a high-performance universal waterproofing system
specifically developed for long term protection of all types of surfaces.

Waterproof & protect all types of surfaces like concrete roof slabs, parapet walls, tiled roofs, valleys, ridges, vents, flashings, balconies, cement dams, ponds etc.

Ready-to-use single component, water-based flexible UV resistant acrylic waterproofing coating.

HydroSeal HF is an alternative to solvent-based and moisture curing polyurethane membranes.

HOW IT WORKS

ROOF, SLAB & WALL WATERPROOFING

HydroSeal HF is a synthetic nano-polymer, high-performance universal waterproofing system specifically developed for long term protection of all types of roof surfaces, concrete roof slabs, parapet walls, tiled roofs, valleys, ridges, vents, flashings etc. Due to its low hazards characteristics, excellent UV stability and ease of application, acrylic co-polymer liquid applied waterproofing emulsions are becoming more popular, particularly in warm and moderate climate regions.

KEY BENEFITS

HydroSeal HF Flexible Synthetic Nano Polymer Waterproofing

1/ EXCEPTIONAL ADHESIVE PROPERTIES

Used for waterproofing of roofs, parapets, patios, hollow-core slabs, Balconies, retaining walls, foundations, water features, dams etc. It bonds to existing torch-on systems and covers these jointed surfaces with a seamless membrane.

2/ DURABLE, LONG-LASTING & WEATHER RESISTANT

Long-lasting low maintenance flexible UV Stable & weather resistant coating that is durable, colourfast and highly resistant to acids and chlorine.

3/ TIME SAVING APPLICATION

HydroSeal HF is a single component, elastomeric, acrylic waterproofing and protective coating that can be applied by brush, roller or spray. Will not re-emulsify, once cured. Handles permanently wet conditions.

4/ ECO-FRIENDLY

Environmentally friendly, water-based coating contains no toxic solvent and/or chemicals. It is virtually odourless and has a Low VOC <1 %

CASE STUDIES

HYDROSEAL HF AT WORK

Water-based liquid-applied acrylic roof, wall & floor waterproof coating. HydroSeal HF has excellent weathering properties, adhesion and is tough, flexible and non-toxic. It can be used to seal stable flashings, parapet walls, concrete roof slabs, balconies, under tile, joints, laps and roofing screws on corrugated roofs and gutters.

Waterproofing the concrete roof slabs at a newly built house in Hammanskraal was the ideal setting to make use of the HydroSeal HF waterproofing system.

Torch-on waterproofing maintenance is expensive. The HydroSeal HF waterproofing system offers a cost-effective alternative.

Acrylic waterproofing systems gives you a seamless waterproof coating that is long-lasting, low maintenance, UV Stable & weather resistant. The acrylic waterproofing system is a strong yet flexible waterproofing solution that can withstand high water pressure, high temperatures and move with the structure.

Acrylic waterproofing is most commonly used on roofs, parapets, patios, hollow-core slabs, balconies, retaining walls, foundations, water features, dams etc. It bonds to existing torch-on systems and covers these jointed surfaces with a seamless membrane.

Utilising a stitch-bonded polyester membrane will enhance and strengthen the acrylic waterproofing system.

concrete slab waterproofing

Bitumen used to be a good waterproofing material due to its nature. But with advances in technology and eco-friendly waterproofing systems, the liquid applied acrylic waterproofing solution has changed the waterproofing market and become the preferred choice when it comes to waterproofing system for new roofs and refurbishments. Acrylic waterproofing systems are easy to apply, environment-friendly, more economical, high-performance and tools can easily be cleaned with water.

Step 1 Remove all lose and broken bits. The substrate must be clean, dry and properly cured.

Step 2 All surface must be primed with Penetrar to bind, enhance & improve the adhesion for membrane & waterproofing coating.

Step 3 All gaps and holes must be filled in with fibre cement & Penetrar enhanced mixture.

Step 4 Use stitch bonded polyester membrane on corners, cracks, joints & overlaps to strengthen waterproofing system. Apply using Repello to embed membrane into base coat.

Step 5 Once dry apply 3 coats of liquid HydroSeal HF waterproofing membrane. Allow to dry in between each coat.

Step 6 Match colour of roof by painting the waterproofing.

Step 7 Paint roof if required.

Using an acrylic waterproofing system that is reinforced with a stitch-bonded polyester membrane has become the preferred method to waterproof flat roofs on residential properties.

The process involves applying a five-layer acrylic waterproofing system that consists of 1. Prime surfaces with Penetrar - a multi-purpose co-polymer ready-to-use primer & keying agent, 2. Lay stitch-bonded polyester membrane covering the complete surface embedded using Repello and 3. Apply three coats of liquid HydroSeal HF waterproofing membrane to form a seamless waterproofing coating that is long-lasting, low maintenance, UV Stable & weather resistant.

There are many types of waterproofing systems on the market but the system that attracts the most attention is the acrylic waterproofing system that is easy to use, eco-friendly & long-lasting. Materials used for waterproofing a roof includes:

  • Penetrar: Multi-purpose co-polymer ready-to-use primer & keying agent + promotes adhesion.
  • Fibre Cement: Cement, fibre & Penetrar enhanced mixture
  • Repello: Multi-purpose co-polymer product used to seal & protect concrete, face brick walls and cladding
  • Membrane: Stitch bonded polyester membrane to enhance and strengthen waterproofing system.
  • HydroSeal HF: Ready-to-use single component, water-based flexible UV resistant acrylic waterproofing coating designed for a wide range of waterproofing applications in the built environment.

Newly poured concrete roof and untreated concrete slabs are pours and not waterproof. The preferred waterproof system to use will be a penetrating roof sealer that bind & stabilises friable surfaces of a concrete roof and a seamless waterproof coating that is durable, long-lasting & weather resistant.

The best way to seal a concrete roof is to apply a five-layer acrylic waterproofing system that consists of 1. Prime surfaces with Penetrar - a multi-purpose co-polymer ready-to-use primer & keying agent, 2. Lay stitch-bonded polyester membrane covering the complete surface embedded using Repello and 3. Apply three coats of liquid HydroSeal HF waterproofing membrane to form a seamless waterproofing coating that is long-lasting, low maintenance, UV Stable & weather resistant.

Torch-On Waterproofing is a bitumen-based product that requires a torch to heat fuse the bitumen material directly onto the roof or slab. The torch-on is applied in overlapping sheets that create a waterproof barrier.

After a few years, the torch-on waterproofing overlaps and drain ends begin to crack and separate exposing the slab/substrate. By using a product like HydroSeal HF, torch-on applications can be maintained and updated with a seamless seal throughout the entire surface.
