Sectional Title


Successful waterproofing in Johannesburg to roofs is dependent on a proper assessment and the structure of the building.
Since all waterproofing and roofs require maintenance at various intervals, it is recommended that roofs are inspected periodical to prevent future leaks.
We have repaired and waterproofed many different structures and used many different products over the past 10 years.
This knowledge qualifies us to correctly assess and solve all waterproofing problems.
Waterproofing works carry a guarantee of up to 10 years depending on the  maintenance schedule.
A wide range of building defects can result in rainwater entering the building. The symptoms are usually obvious, for example, water dripping through a ceiling.

Acrylic waterproofing system

The Acrylseal system consists of a combination of Acrylseal Waterproofer, and Acrylseal Membrane.
The most popular applications for the Acrylseal system are:

  • Waterproofing small roof areas
  • Waterproofing parapets
  • Repairing damaged flashings

Application of the Acrylseal system is simple. However, before starting, one should ensure that the area to be waterproofed is sound, stable, and free of detritus, oil, or any other substance that may prevent the system from achieving a good bond to the substrate.

The Acrylseal Waterproofer is first applied to the surface to be waterproofed. The Acrylseal Membrane is then applied immediately on-to the wet Acrylseal Liquid. Once the Acrylseal Liquid has dried (2-24 hours, depending on weather conditions) a second coat of Acrylseal Liquid should be applied over the Acrylseal Membrane.

Torch-on Membrane

Torch-on membrane is a bitumen-based waterproofing product which is heat-fused to underlying substrates. It is sold in a variety of thicknesses with single or dual re-enforcement with polyester or fiber glass.
Typical uses are the waterproofing of:

  • Roof slabs
  • Balconies and patios
  • Foundation walls
  • Retaining walls

Surfaces must be sound, clean and free from any contaminants and primed with one coat of Bitumen Primer prior to the application of the torch-on membrane. Once cooled, the membrane should be protected with 2 coats of Bitumen Aluminium Paint for UV protection or covered with a screed and tiling.
Care should always be taken to ensure good overlaps between rolls and to lap any side walls to prevent water ingress. Refer to manufacturer’s guides for full application details.


The product is a water-based, rubberized bitumen emulsion, used with a membrane to form a liquid waterproofing system.
Typical uses:

  • All types of Flashings.
  • Parapet Walls.
  • Flat roofs smaller than 500m2.
  • Sealing joints, laps and roofing screws on corrugated roofs.


  • Suitable for use in potable water conditions.
  • Can be applied to damp surfaces.
  • Tough and flexible.
  • Excellent adhesion.

DO NOT apply if rain is imminent.
The product is not UV stable and requires a suitable bitumen-based reflective coating.

Damp proofing

Damp proofing

Signs of damp include a band or tide mark which is clearly visible. Hygroscopic salts deposits, e.g. chlorides or nitrates on the wall, bubbling paint or fretting plaster confirm a problem exists or has existed previously.
A complete survey by one of our trained surveyors, aided by an electronic moisture meter, will determine the extent and causes of the damp problem.
A complete and proper recommendation is only given after a thorough investigation.
We have treated all types of damp professionally for the past 10 years.

Rising Damp

Rising damp in buildings may be defined as the vertical flow of water up through a permeable wall structure or floor, the water being derived from ground water. The water rises through the pores (capillaries) in the masonry or concrete by a process loosely termed “capilliarity.” In other words the masonry acts like a wick.
The treatment method will depend on whether the rising damp is affecting a solid floor, or is rising up a wall (as shown on the photograph).
Treatment of Rising Damp in solid floors:
This happens most regularly where developers have failed to fit dpc sheeting beneath the slab or when an existing dpc has failed. Several new products are now available to stop Damp rising through floor slabs, notably ECS Epoxy Floor Coating and Dry Base Vapour Membrane. Where the floor slab is contaminated (e.g. oil stains or bitumen) or hydrostatic water pressure is excessive it may be necessary to lay CDM Industrial Membrane over the slab after which a new screed or wooden flooring can be fitted over the membrane.

Treatment of Rising Damp in walls:

Dryzone damp-proofing cream, or Microsilan DPC fluid is injected into the wall at floor level to provide an impermeable barrier, preventing the damp rising up the wall. Affected plaster is removed and replaced with a plaster applied to the specification given in our Renderguard Gold data sheet.

What is Lateral

Lateral damp is when moisture is allowed to enter the structure in a horizontal direction. Gravity then causes the downward movement of the damp into other areas. Penetrating damp can create isolated patches of dampness that increase in size after periods of heavy rain. The damp can occur at any level, unlike Rising Damp which usually rises from the ground up to 1.2 metres high. Lateral or penetrating damp is usually from a source too difficult to control and only an expert with a moisture metre detector will evaluate the difference in rising and lateral damp. Sometimes the problem may also require a plumber to pressure test the pipes to eliminate them as the problem.

Causes of Lateral Damp

  • Leaking water supplies or waste pipes
  • fretted mortar joints
  • defective brickwork
  • failure of tile grouts in showers and other wet areas
  • poorly functioning membrane in wet areas
  • cracked render
  • poor flashings
  • defect in adjacent property outside the owners control
  • air-conditioning or hot water system overflows can also lead  to small localised patches of dampness.

All Damp proofing work carries a guarantee.
