Renderoc Plug is a fast-setting, ready-to-use cementitious plugging compound designed to instantly stop running or seeping water through cracks, joints, and holes in concrete and masonry structures. It expands slightly on setting, forming a tight seal that blocks water ingress effectively.
The product is ideal for emergency repair situations such as water leakage in basements, tunnels, lift pits, water tanks, retaining walls, and underground structures. Renderoc Plug sets quickly even under wet conditions, allowing rapid return to service.
It is easy to mix with water, simple to apply by hand, and provides durable, long-lasting performance. Renderoc Plug is suitable for both residential and commercial repair works where immediate waterproof sealing is required.
