Sika MonoTop®-108 Water Plug IN
Fast-Setting Cementitious Water Stop Mortar
Authorized Project Distributor — Sika India | Space Arc Engineering, Ghaziabad
Product Overview
Sika MonoTop®-108 Water Plug IN is a one-component, rapid-hardening cementitious mortar specifically formulated for the emergency plugging of active water leaks and cracks in concrete and masonry structures under hydrostatic pressure. When mixed to a stiff putty consistency, it begins to set within 1–3 minutes and achieves sufficient strength within 5–10 minutes to withstand flowing water pressure. This extremely rapid action makes it the product of choice for emergency repair of water leaks in basements, tunnels, water retaining walls, dams, and any structure experiencing active seepage. Space Arc Engineering distributes Sika MonoTop®-108 Water Plug IN for emergency waterproofing repair across Delhi NCR and UP.

Frequently Asked Questions
How do I use Sika MonoTop-108 Water Plug IN on an active leak?
Mix a small quantity with minimum water to a stiff putty consistency. Hold the mixed mortar firmly over the leaking crack or hole for 2–3 minutes while it hardens. Apply with firm sustained hand pressure until the material is hard and the water flow is stopped.
Can Sika MonoTop-108 Water Plug IN be used to plug leaks in water tanks?
Yes. MonoTop-108 Water Plug IN is suitable for emergency plugging of leaks in potable water tanks and reservoirs. After the leak is stopped, follow up with a comprehensive waterproofing system such as SikaTop-107 Seal IN for long-term protection.
Is the set time of 1–3 minutes always reliable?
Set time is temperature-dependent. At higher temperatures (above 30°C), setting is faster; at lower temperatures it slows. Always prepare only small quantities and work quickly once mixing begins.
