Concrete Waterproofing Chemicals We Offer
POLYALK CP 293
SUNCRYSTALMIX
SUNCRYSTALMIX is a powdered crystalline waterproofing admixture added to concrete or mortar during batching. It reacts with moisture and cement particles to form crystals within the concrete matrix, restricting water penetration and helping seal hairline cracks. Suitable for reservoirs, foundations, basements, retaining walls, swimming pools, sewage tanks, and other water-retaining structures.
POLYTANCRETE IWL
POLYTANCRETE IWL is an integral waterproofing liquid admixture for concrete and mortar. It reacts with water-soluble compounds to form stable, insoluble silicates that create an internal barrier against water penetration. The admixture reduces water permeability by up to 60%, minimises porosity and capillary action, and improves workability while making concrete and mortar denser.
Key Projects
The polymer-modified mortar improved adhesion, water impermeability, tensile and flexural strength while helping compensate for shrinkage. The completed repair provided a durable, water-resistant finish across the treated concrete areas.
Key Projects
The coating forms an impermeable, alkaline-compatible co-matrix film with cement, providing protection against water and sulphate exposure. The completed treatment provided a watertight and durable finish for the concrete process channels.

Frequently Asked Questions (FAQ)
What is a waterproofing chemical for concrete, and where is it used?
A waterproofing chemical for concrete helps protect concrete surfaces and structures against water ingress. Depending on the product, it can be used for RCC roofs, external walls, bathrooms, water tanks, reservoirs, sunken areas, and other concrete applications.
Which concrete waterproofing chemicals are suitable for my project?
The appropriate product depends on the concrete surface, exposure, existing condition, and application. Different concrete waterproofing chemicals may be suited to exposed surfaces, water-retaining structures, roofs, walls, or other areas requiring waterproof protection.
What is the difference between waterproofing coatings and chemical admixtures for concrete?
Waterproofing coatings are applied to concrete surfaces to create a protective barrier. Chemical admixtures for concrete are incorporated into the concrete mix to modify its properties. The appropriate approach depends on the waterproofing specification and construction requirements.
Can waterproofing chemicals be used for concrete roof waterproofing?
Yes, products designed for roof applications can be used for concrete roof waterproofing. The system should be selected according to the RCC surface, roof condition, exposure, movement, drainage, and whether the roof is new or already in service.
Can concrete waterproofing be carried out on an existing structure?
Yes. Existing concrete can be waterproofed, but the condition of the substrate should first be assessed. Cracks, damaged concrete, previous treatments, contamination, and other surface defects may need to be addressed before applying the waterproofing system.
How should a concrete surface be prepared before waterproofing?
Surface preparation depends on the selected system and the condition of the concrete. The substrate generally needs to be sound and suitable for application, with defects or existing materials addressed according to the requirements of the specified waterproofing product.
Is one waterproofing chemical suitable for every concrete application?
No. Roof slabs, external walls, water tanks, below-ground structures, and industrial concrete can face different exposure conditions. The waterproofing system should therefore be selected according to the structure and its specific requirements.
How do I choose between surface waterproofing and integral waterproofing for concrete?
The choice depends on the structure, construction stage, water exposure, and project specification. Surface systems are applied to the concrete, while integral waterproofing is incorporated into the concrete mix using suitable admixture technology.
