Product Description

Fosroc Conplast WL Integral Waterproofing Liquid is a premium liquid admixture designed to permanently reduce the water permeability of concrete and cement-sand mortars. Available in a large 20 Litre structural configuration, it is ideal for high-volume residential pourings or demanding commercial jobsites where structural moisture resistance is mandatory. The fluid integrates smoothly into the batch water, dispersing uniformly to block micro-capillary paths inside the cured matrix without altering initial or final setting times. It is a chloride-free formulation that protects internal reinforced steel from rust, while preserving or enhancing long-term compressive strength boundaries. Adhering fully to strict IS:2645-2003 waterproofing standards, this admixture provides durable structural protection against dampness and internal water movement.

FAQs

1) How do I calculate how much Fosroc Conplast WL I need for my project?

The standard dosage is 200 ml of liquid per 50 kg bag of cement. To find your required volume, verify the total number of cement bags your mason or contractor has estimated for the pour. For example, a 20 Litre drum will treat exactly 100 bags of cement. If your project requires 50 bags of cement, you will use exactly half of a 20L drum (10 Litres).

2) Can I use this product with any type of cement?

Yes, Conplast WL is highly compatible with nearly all standard commercial cements, including Ordinary Portland Cement (OPC) and Portland Pozzolana Cement (PPC). However, it must not be used with High Alumina Cement. Confirm the cement type with your site engineer or material supplier before mixing.

3) Do I still need external waterproofing coatings if I use Conplast WL inside the mix?

Conplast WL is an integral waterproofer, meaning it reduces the permeability of the core concrete structural matrix itself. While it provides excellent protection for general wet areas, critical high-risk environments like exposed flat roofs, basements under high water tables, and deep water tanks should combine this product with an external membrane or coating (such as Fosroc Brushbond) for a multi-layered defense system.

4) Does adding this liquid alter the drying or working time of my concrete?

No, when used at the recommended dosage rate, Conplast WL has no significant effect on the initial or final setting times of concrete or plaster mortars. It improves operational workability, allowing masons to achieve better compaction and fewer voids without modifying their standard placement schedule.

5) What happens if the product has been stored in a warehouse for a few months?

The product features a reliable 12-month shelf life when stored in its original, unopened container under sheltered, cool conditions. If it has been sitting for a few months, simply stir or shake the container gently before opening to ensure uniform consistency before adding it to the gauging water.
