The number of waterproofing materials available to the home owner and building contractor have steadily increased over the years, making the task of choosing the best product for a particular waterproofing or roofing problem all the more difficult to make. These products range from torch on membranes and self adhesive membranes to acrylic waterproofing systems, polyurea and polyurethane sealants. One of the more popular waterproofing products in South Africa remains the torch on membrane.

Torch on membranes

These waterproofing membranes consist primarily of bitumen modified with APP and ATACTIC ingredients. An important part of the membrane is the reinforcement sandwiched in the centre which gives the waterproofing membrane its dimensional stability. Different brands of torch on membranes are available, but few possess the stability to operate optimally in African climates. Anker Projects is aware of this important distinction and has therefore aligned itself with manufactures that provide torch on waterproofing systems suited for local climatic conditions..

Self Adhesive Membranes

Self adhesive membranes are well known for their elasticity and flexibility. These waterproofing membranes consist of SBS modified bitumen, which gives it its flexibility and elongation properties. Unlike APP modified bitumen membranes they are not resistant to ultra violet rays of the sun. Self adhesive bitumen waterproofing membranes are largely used in covered situations or protected from the harmful rays of the sun. Most self adhesive waterproofing membranes require a primer to be applied on the surface before its application, this serves to settle the dust facilitate adhesion of the product to the substrate. Anker projects have proven expertise in the application of self adhesive waterproofing membranes in covered situations in the Cape Town waterproofing and roofing industry.

Acrylic Waterproofing

Acrylic waterproofing systems are strictly speaking waterproofing compounds that have a water base. They are often mixed with other materials like paint, cement or bitumen. These waterproofing systems are typically easy to apply either by spray gun, roller or paint brush. The acrylic waterproofing system affords excellent waterproofing capabilities if applied according to manufactures instructions. Anker projects have completed many projects successfully that have required the use of acrylic waterproofing systems. Again the use of acrylic waterproofing systems must take into account many factors like the substrate, movement and more.
