Common questions
About waterproofing
What is the difference between liquid-applied and cementitious waterproofing?
Liquid-applied membranes cure into a seamless elastic film and bridge movement, which suits roofs and podium decks exposed to thermal cycling. Plain cementitious slurries bond rigidly, withstand water pressure well and tolerate very little movement, so they suit tanks and basement walls. Polymer-modified cementitious systems sit between the two and will bridge fine cracks. Tell us the element and the exposure and we will point you to the right Sika system.
Which waterproofing products hold up to Saudi roof temperatures?
Roof surface temperatures in the Kingdom regularly exceed what a general-purpose membrane is rated for, and application windows are limited in summer. The Sika range includes systems specified for high-temperature exposure and UV resistance. Ambient and substrate temperature limits are stated on each product's data sheet — send us your location and we will confirm which options are suitable.
Do you supply waterproofing approved for potable water tanks?
Yes. On its potable water solutions page Sika lists waterproofing mortars — SikaTop-107 Seal, Sikalastic-1K and Sika-110 HD — for the internal waterproofing and protection of potable water reservoirs, alongside multi-layer epoxy resins, hot-spray polyurea and TPO sheet membranes. Of those we stock SikaTop-107 Seal AE, and we also hold SikaSwell A and Sikadur-Combiflex SG for joints and Sika Injection-201 CE, which Sika lists as a PU injection resin with drinking water approval. Not every tank product is a potable system: Sikagard-320 EPS is specified for non-potable structures. The applicable certification is stated on each data sheet. This is not a detail to assume — tell us the tank is for drinking water when you enquire and we will supply only products carrying the relevant approval.
Always refer to the full Sika technical data sheet before application.
