SikaProof A (-05/-08/-12)
Description
SikaProof® A offers a fully bonded, pre-applied waterproof coating system for durable below-grade concrete protection.
Product Description:
SikaProof® A (-05/-08/-12) is an advanced sheet-applied waterproofing membrane system designed to deliver long-lasting protection for reinforced concrete structures. This high-performance, fully and permanently bonded sheet membrane system is engineered for superior waterproofing in demanding below-grade applications.
The system consists of an embossed polyolefin (FPO) membrane laminated with a sealant grid and a robust non-woven fleece. This unique composite structure forms a continuous, secure bond with fresh concrete, creating a watertight barrier that prevents lateral water migration in the event of damage or puncture.
A key advantage of SikaProof® A lies in its cold-applied, pre-applied installation process. This means no heat or open flames are required, making it safer and more environmentally friendly. The membrane is laid before steel reinforcement is fixed and concrete is poured, ensuring a seamless bond and reducing the risk of installation errors.
Ideal for a variety of below-grade applications, SikaProof® A is particularly suited for:
- Basements and foundations – keeping structures dry and protected from groundwater infiltration.
- Underground parkades – preventing moisture ingress in high-traffic areas.
- Tunnels and retaining walls – offering reliable, durable waterproofing even in challenging conditions.
Its design helps to protect structures from water ingress, aggressive chemicals in the soil, and freeze-thaw damage. The system also contributes to the long-term durability of reinforced concrete, reducing maintenance costs over the life of the structure.
Whether used in commercial, residential, or infrastructure projects, SikaProof® A delivers consistent performance, backed by Sika’s proven expertise in waterproofing technology. By integrating this waterproof coating system into the construction process, project teams can achieve faster, safer installation and long-lasting structural protection.
With its combination of innovative materials, secure bonding technology, and environmentally conscious installation, SikaProof® A is a trusted solution for projects where waterproofing is critical..
