Client Masetlaoka Scott Wilson Site Various Polokwane Municipalities Scope Concrete Waterproofing and Crack repair Where Polokwane, Limpopo


Sanika Waterproofing Specialists were contracted to assist with waterproofing of the poorly constructed reservoirs in the Acornhoek and Bushbuck Ridge areas by Masetlaoka Scott Wilson, whom are the civil, water and consulting engineers for the Department of Water Affairs, South Africa.

The newly constructed reservoirs had severe leaks and flaws through the joints, cold joints, tie holes and through the concrete. These reservoirs are a vital water source for the people in these rural area and therefore an absolute watertight solution for potable water was required.

Due to the value of water in these areas, Masetlaoka Scott Wilson made the informed decision to award Sanika with the contract to perform Kryton’s Krystol Crack Repair and T1 and T2 slurry waterproofing systems to render this reservoir completely waterproof.

The Krystol line of products are certified safe for contact with potable water by NSF International (certifies to NSF/ANSI std. 61) and have a zero volatile Organic Compound (VOCs).


Due to the deteriorating concrete in the reservoirs, it was determined that a waterproofing solution was required before they were commissioned for use.

Sanika’s solution was to use Kryton’s Krystol Crack Repair System, consisting of Krytsol T1 and T2 as well as Krystol Bari-Cote, on the cold joints and tie holes where water penetration was evident form the flood tests. ONLY Kryton can waterproof water containment structures from the negative side while the structure is filled and still in operation.

The Reservoir has now been commissioned for use with no leaks and is supplying our most precious resource to this rural area.
