Universal Roofing often has to explain the reason flat, concrete roof slabs need waterproofing? Waterproofing additives in the concrete composition, still do not create a water-tight seal. Concrete roof slabs expand and contract during hot and cold conditions. This to water leaks on the perimeter of the concrete slab. Customers often call Universal Roofing out to repair leaks on concrete roof slabs and balconies.

Universal Roofing manufactures our waterproofing solutions in house. Our high build, hybrid polymer waterproofing system in 2 variants namely Eco-flexx (grey) and Uni-flexx (white). Widely used over the last 15 – 20 years. Tried, tested  and trusted with different roof types and roof substrates. Eco-flexx (grey) and Uni-flexx (white) have been very successful in creating reliable waterproofing solutions.

Concrete roof slabs and other roof types:

These include concrete roof slabs, pitched cement tiled roofs, clay-tiled roofs, boarded bitumen roofs, corrugated, and IBR steel roofs.

All of these tests have yielded superior results.

Universal Roofing is committed to the environment and because of this Eco-flexx (grey) and Uni-flexx (white) waterproofing systems are cold-applied. This is also in line with international standards which are moving away from oil-based systems. 

Although we suggest using our innovative waterproofing system on new projects. Torch-on bitumen waterproofing systems are still widely used, as a result of this we do also conduct routine maintenance to bitumen waterproofing.

We also offer new torch-on applications at the customer’s request.
