Cementitious waterproofing provides a reliable solution for protecting concrete and masonry surfaces from moisture and water ingress. LeakShield by Multichem Group is a single-component cementitious waterproofing coating designed to help protect concrete, brickwork, blockwork and cement-rendered surfaces from water and moisture.
It is suitable for applications such as basements, foundations, water tanks, swimming pools, wet areas, balconies and planter boxes, and can be applied to horizontal, vertical and overhead surfaces using suitable methods.
It consists of Portland cement, well-graded quartz sand, and active polymer-enhanced special chemical ingredients (with nanotechnology), making a hard yet flexible membrane. Supplied as a powder and mixed with water before application, to form a dense protective barrier, offering a practical and versatile cement-based waterproofing solution for a wide range of construction requirements.
Even a good waterproofing product needs proper application. The surface should be clean, strong, and free from dust, grease, loose material, and other contaminants before application. Correct mixing, application, and curing help the coating perform as intended.
In other words, the right product and the right application work together to deliver effective waterproofing.
Coverage: Damp proofing: 1.0-1.2 kg/m2 (8.33-10 ft2/kg); Waterproofing: 1.25-3.0 kg/m2 ( 3.3-8.0 ft2/Kg

Waterproofing: 7 bar for 3kg/m2
The recommended storage period is 12 months, provided the material is kept at room temperature.
Waterproofing is not just about stopping visible leaks; it helps control moisture before it develops into a larger maintenance concern. Although concrete appears solid, its pores and capillary pathways can allow moisture to move through the structure, and prolonged exposure may contribute to deterioration and affect durability.
An effective waterproofing chemicals creates a protective barrier that helps reduce moisture ingress and supports the long-term performance of concrete and masonry surfaces.
Capillary leakage occurs when moisture moves through the microscopic pores and interconnected capillary pathways within concrete and masonry. These pathways are typically nanometre to micrometre in size and can allow moisture to migrate through the substrate. LeakShield forms a dense cementitious waterproofing to concrete over the surface. This helps reduce capillary water penetration and moisture ingress. When properly applied to a prepared substrate, it helps protect concrete and masonry from dampness and water-related deterioration.
Cementitious Waterproofing is an investment in the durability of a structure. Whether the project involves a basement, foundation, water tank, swimming pool, wet area or concrete structure exposed to moisture, the waterproofing system needs to be compatible with the substrate and site conditions.
LeakShield by Multichem Group combines a single-component cementitious formulation with polymer-enhanced chemistry to create a dense waterproof barrier for a wide range of concrete and masonry applications.
The result is a waterproofing approach focused not merely on covering a surface, but on protecting the underlying structure from unwanted moisture ingress.
Effective waterproofing starts with understanding the structure, exposure conditions and the right cementitious waterproofing system for the application. Multichem Group provides reliable waterproofing solutions for a wide range of concrete and masonry requirements, including basements, foundations, water tanks, swimming pools, balconies and wet areas. As part of our waterproofing portfolio, LeakShield offers a practical cementitious solution for suitable applications, helping protect surfaces against moisture and water ingress.
With the right product, proper surface preparation and professional application, Multichem Group helps deliver designed to support the long term protection and durability of structures.
It forms a dense surface layer that helps reduce capillary water penetration and moisture ingress.
LeakShield can be applied using brush, putty trowel or spray techniques. The substrate must first be properly prepared, cleaned, and saturated without standing water.
A powder-to-water ratio of 5:2 by volume, with approximately 7 litres of water for a 25 kg bag. Application should follow the current technical datasheet and project requirements.
LeakShield can be applied using a brush, putty trowel, or spray technique.
Correct curing, along with proper mixing and application, helps the coating perform as intended.
