Welcome to Sanika Waterproofing

Sanika Waterproofing Specialists has been firmly entrenched in the specialist waterproofing, industrial coating and roofing industry since 1987.

We are the proud industry leaders in insulative boarded maintenance free waterproofing systems in Southern Africa as well as the exclusive approved distributors of Kryton Crystalline Concrete Waterproofing Products, Emseal expansion jointing systems and RiveStop tie-hole waterproofing products in Southern Africa.

We are actively involved in roofing and waterproofing consultation, water management and corrosion protection systems and concrete crack repair, rejuvenation and concrete waterproofing in the commercial, industrial and mining industries throughout Southern Africa.

We pride ourselves in preparing long term, cost effective and high quality concrete rejuvenation and waterproofing solutions, painting and waterproofing coating systems nationwide.


Sustainable building practices are more important now than ever before. Providing a durable and environmentally-friendly solution to concrete leaks and deterioration can directly impace the long term enviironmental and financial viability of a structure.

Most concrete crack repair methods are only temporary fixes, and contain harmful toxins. By using integral crystalline waterproofing technology, as well as decades of experience behind us, we are able to transform cracked and leaking concrete into a permanent, water-resistant barrier.


When Kryton’s Krystol concrete waterproofing products are applied to the surface of damaged concrete, the Krystol proprietary chemicals react with water and un-hydrated cement particles to form insoluble needle-shaped crystals. These crystals fill capillary pores and micro-cracks in the concrete to block pathways for water and waterborne contaminates.

Krystol will continue to give the concrete structure a self-sealing ability. If water is re-introduced through a rise in hydrostatic pressure or through hairline cracks, Krystol will initiate further crystallization to ensure permanent waterproof protection.

Krystol waterproofing systems create completely watertight concrete structures that are self-sealing and able to withstand hydrostatic pressure for the life of your structure.

Since this waterproofing technology becomes an integral and permanent part of the concrete itself, its’ effectiveness as a waterproofing barrier is not contingent on its’ ability to form and maintain a coating or membrane on the surface of the concrete. This means that, unlike surface-applied membranes, crystalline waterproofing technology can never be punctured, damaged or worn away, and will last the lifetime of the concrete.

Designed and developed by Sanika Waterproofing Specialists over 20 years ago, this roof cladding system eliminates water penetration and thermal radiation in any structure with a concrete, corrugated or IBR profile roof.

This waterproofing system has been successfully installed at many institutions such as Impala Platinum Refineries, M-Net, Rand Refineries, OR Tambo International Airport, Spar Group to name but a few.


With the application of a laminated insulative panel, profiled to the sheet design and enclosed with a maintenance-free torch on membrane, this system renders the roof area totally waterproof and offers a ten year maintenance-free guarantee. The installation of this insulative and 100% watertight system eliminates any need for stripping of the existing roof as the installation is performed on the top side and uses the existing sheeting as a support platform.

General mortar damp and rising damp can cause huge problems in any type of masonry brick structure. Left untreated, damp in the plasterwork can lead to damage to concrete, brick and wood structures as well as wet- and dry-rot. Although damp is thought to affected older structures, incorrect waterproofing and ventilation in newer structures can easily lead to damage and costly repairs.

As waterproofing specialists, our ultimate goal is to create and waterproof structures from foundation up. By using crystalline waterproofing technology from Kryton, we are able to provide long-term protection in rendering/plastering mortar, masonry mortar and concrete masonry units. Krystol Mortar Admixture™ (KMA) can often be used in place of externally applied surface sealers to protect against water and waterborne contaminants and can be easily incorporated into the existing mix design and application processes.


KMA contains Kryton’s unique and proven Krystol® technologywhich reacts with the cement particles to form millions of needle like crystals, reducing both permeability and absorption of the mortar by filling the naturally occuring pores and voids in cementitious mortar.

Krystol® technology helps to simplify installation and provide superior performance such as its ability to self-heal minor cracks and withstand water under pressure.

We pride ourselves on supplying and installing the highest-quality, innovative and durable materials for use in sealing small and large structural joints in foundations, decks, walls, and floors. Having installed hundreds of thousands of linear metres of Emseal expansion jointing products throughout Southern Africa, we have cemented our reputation as the leader in expansion jointing systems in the Southern African area.


There are numerous Emseal Expansion Jointing options available depending on the sealing needs. Sanika, along with the use of Emseal products allow for a simple installation and non-invasive anchoring with 100% movement (including shear movement). There is no tension on the bond line or on the surface as the Emseal product relies on the back-pressure on both sides of the substrate and not only on the epoxy adhesive.

The waterproofing of any metal roof can be a complex task, however with our extensive experience in the industry, we are able to quickly and effectively waterproof corrugated, Kliplock and IBR profile roofs and guarantee a watertight seal.


The metal corrugated, Kliplock or IBR profile roof is cleaned, rust is removed and primed in preparation of the application of a non-woven polyester waterproofing membrane impregnated with a 100% pure acrylic over crosslaps, overlaps, bolt-heads and pipe-penetrations. The impregnated membrane can then be sprayed using high-pressure airless spraying equipment with a UV stablised industrial grade waterproof coating. This waterproof coat ensures a 100% watertight and rust proof surface as well as an aesthetically pleasing finish.


  • 100% watertight seal
  • Excellent adhesion to the concrete profile
  • Aesthetically pleasing finish
  • Rot and mould proof
  • Acid and alkali resistant
  • Puncture resistant
  • Life span exceeding 25 years



With our extensive experience in the waterproofing industry, we are able to quickly and effectively waterproof tiled roofs and guarantee a watertight seal.


Ridges and valleys can cause the biggest waterproofing problems with a tiled roof. Water penetration on these joins can be rectrified with the use of torch on waterproofing membranes and non-woven polyester waterproofing membranes impregnated with a 100% pure acrylic.

For a project of this type, roof tiles in valleys need to be lifted and a torch on waterproofing membrane is installed below the tiles to increase the surface area of the valley and to prevent the ingress of water.

We ensure that the valleys have enough girth not to restrict the flow of water through them.


  • Absolute water-tightness
  • Rot proof
  • Aesthetically pleasing finish
  • Non-invasive waterproofing
