Acrylic Waterproofing systems

 

Acrylic waterproofing systems are not used to combat standing water. The most commonly used system is a fibre re-inforced acrylic system which is used successfully on bands, sills, parapets and is also commonly used in the overcoating the areas of repaired areas where re-cracking of mortar repairs is most prevalent. This system can be used in conjunction with non-rot polypropylene membrane to reinforce the affected area.

 

 

Bitumen-based Waterproofing system

 

All surface areas, sand and cement screeds, must be prepared to the correct falls, with a minimum of 1:60 being achieved. No hollow, sharp or contaminated areas must be present.  The moisture content is not to exceed 7% prior to torchon applications. Prime all surfaces with a bitumous primer, including all verges, and around outlets and protrusions and allow the solvent to flash off. Extremely porous surfaces should be re-primed. Full bore outlets, thresholds, pipe up stands to have 4mm torchon bonded to the surface including their gussets. There after  apply 4mm, non-woven polyester reinforced, fully bonded to the bituprime primed surface by means of ‘torchon fusion’ using propane gas, ensuring that the side and end laps are 100mm and 150mm respectively. All surfaces must receive two coats of bitumous aluminium paint to protect the torchon from the elements.

Raw unpainted plaster or Face Brick

 

For aesthetic reasons some clients do not want to paint their face brick, concrete, stone, fibre cement or unpainted plaster and wish to keep the look.
In such situations after thorough cleaning and preparation the surfaces can be coated with a silane/siloxane water based solution.

 

  • Water based with strong water-repellent capacity
  • Improves the facades resistance to the ingress of water
  • Allows the substrate to breath, it protects construction materials from wind driven rain
  • Treatment is invisible and does not change the substrate aesthetics
  • Improves the resistance to dirt, and reduces the bonding of fungi, lichens
  • Does not alter the substrate porosity
  • Can be coated with various paint

Elastic fibre reinforced, cement based flexible waterproofing coating

 

Due to its high elasticity of this system, it is applicable on different structures including those subject to thermal movement and vibration such as:

 

  • Waterproofing and protection of hydraulic structures like water storage tanks, concrete pipes, bridge parapets, water canals etc
  • Waterproofing and protection of external walls to be buried below ground
  • Internal waterproofing against hydrostatic water pressure of walls and floors in basements and other below ground structures
  • Waterproofing of terraces and balconies on concrete and old tiles substrates
  • Protection of exposed and weathered, new and existing concrete surfaces, as a flexible, anti-carbonation,chloride and sulphate resistant coating. Also for sealing of concrete surfaces cracked by plastic and hydraulic surface shrinkage.
  • There are many more examples of waterproofing systems which each have their own niche for application. With each and every system applied, we have staff that have received the necessary training from the appropriate manufacturer.
