satisfied customers. We waterproof house roofs including flat roofs, concrete
slab roofs, pitched tiled roofs, balconies, skylights, parapet walls, sidewalls,
chimneys and chimney flashings, leaking chimneys, plumbing vent pipes,
dome skylights, plumbing inspection covers, tiled roofs, roof ridging, IBR
roofs, corrugated roofs and box gutters.
We do waterproofing on any substrate. We have done 1000's of roof
waterproofing contracts in Guateng, including waterproofing Sandton,
Morningside, Fourways, North Riding, Randburg, Roodepoort, Lonehill, Kyalami,
Parkview, Parktown, Pretoria, Centurion, Hartbeespoort, Johannesburg North,
Carlsworld, Midrand, Edenvale, Germiston, Alberton, Craigavon, Northcliff,
Rangeview, Rand Park Ridge, Sandringham, Pretoria East, Kempton Park and all
areas in Gauteng, South Africa.
We also waterproof factory roofs including IBR steel roofs, Corrugated steel roofs,
Box Gutters, Cliplock Roofs and polycarbonate roofs. We have many years of
experience and we are members of the Dampproofing and Waterproofing
Association of South Africa and also the Gauteng Master Builders Association
(Established in 1903). Universal Roofing's range of cold applied liquid Polymer
membranes offer a seamless roof waterproofing solution suitable for use in both
commercial and domestic developments in newly built and refurbished
Over the past two decades, the construction industry has had technological
advances in waterproofing materials, including integral waterproofing systems as
well as more advanced membrane materials.
Integral systems work within the matrix of a concrete structure, giving the
concrete itself a waterproof quality. There are two main types of integral
waterproofing systems: the hydrophilic and the hydrophobic systems. A
hydrophilic system typically uses a crystallization technology that replaces the
water in the concrete with insoluble crystals. Various brands available in the
market claim similar properties, but not all can react with a wide range of cement
hydration by-products, and thus require caution. Hydrophobic systems use fatty
acids to block pores within the concrete, preventing water passage. Crack's in
expansion joints and concrete surface usually allow water to bypass these two
systems. It is therefore reccomended that flexible waterproofing is applied to the
surface to block water before it comes into contact with the concrete. Uni-Flexx
has excellent adhesion, flexibility and durability qualities.
New membrane materials seek to overcome shortcomings in older methods like
PVC and HDPE. Generally, new technology in waterproof membranes relies on
polymer/Polymer based materials that are extremely adhesive to create a
seamless barrier around the outside of a structure.
