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.

ROOF SLAB WATERPROOFING

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.

FREQUENTLY ASKED QUESTIONS

STILL, HAVE SOME QUESTIONS?

Why use an acrylic waterproofing system?

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.

What is the best waterproofing for roofs?

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.

How do I waterproof my roof?

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.

What is the best way to waterproof a flat roof?

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.

Which material is used for waterproofing of roof?

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.

What is the best way to waterproof a concrete roof?

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.

How to do torch on roof maintenance?

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.
