Conplast WL XTRA is an advanced integral waterproofing admixture designed to significantly enhance the durability, density, and water-tightness of concrete and mortar. Manufactured by Fosroc with strict international quality standards, this admixture is widely recognized for its reliable performance, long-lasting protection, and superior waterproofing efficiency across a broad range of construction applications.

In modern construction, water penetration, dampness, and structural deterioration caused by moisture remain major challenges. Conplast WL XTRA addresses these issues by reducing the permeability of concrete and effectively minimizing capillary suction, which prevents water from entering the structure. As a result, the concrete becomes denser, stronger, and more resistant to leakage, seepage, and chemical attack—ensuring long-term structural integrity.

Product Overview

Conplast WL XTRA is formulated using a blend of surface-active agents, plasticizing components, and pore-blocking additives. When mixed into concrete or mortar, it fills micro-pores and capillaries, thereby restricting water movement and significantly reducing absorption.

It complies with IS 2645 standards for integral waterproofing compounds and is widely preferred by engineers, contractors, and large construction companies due to its consistent performance and ease of use.

Key Features & Benefits

1. Exceptional Waterproofing Performance

The primary advantage of Conplast WL XTRA is its ability to block water penetration within concrete mass. By reducing pore interconnectivity, it drastically lowers permeability, making it ideal for water-retaining structures and areas exposed to continuous moisture.

2. Improved Workability Without Extra Water

Conplast WL XTRA enhances the workability of concrete and mortar mixes, allowing smooth placement and compaction without the need for additional water. This ensures optimal strength development and reduces the risk of weak, porous concrete.

3. Increased Compressive Strength

Due to better compaction and reduced water demand, concrete mixed with Conplast WL XTRA develops higher long-term strength. This results in durable structures that can withstand heavy loads and harsh service conditions.

4. Resistance to Cracking & Shrinkage

The admixture minimizes shrinkage-related micro-cracks, which are common in plaster and concrete structures. This helps maintain surface integrity and prevents early deterioration.

5. Enhanced Durability Against Weather & Chemicals

Conplast WL XTRA shields concrete from chloride attack, sulfate exposure, wet–dry cycles, and aggressive environmental conditions. This adds years to the life of RCC structures, foundations, and water-retaining components.

6. Protects Structures from Dampness

It provides strong protection against rising damp, seepage, and moisture ingress in basements, bathrooms, rooftops, and ground-level walls. This helps prevent peeling paint, efflorescence, and fungal growth.

7. Compatible with All Cement Types

Whether using Ordinary Portland Cement (OPC), Pozzolana Portland Cement (PPC), or Portland Slag Cement (PSC), Conplast WL XTRA integrates seamlessly and delivers consistent waterproofing results.

2. Plaster, Mortar & Masonry Work

Adding Conplast WL XTRA to plaster mixes prevents damp patches and moisture absorption. It ensures smoother, stronger, and long-lasting plaster finishes.

3. Water-Retaining & Water-Excluding Structures

Ideal for:

Water tanks

Underground reservoirs

Overhead tanks

Swimming pools

Its superior waterproofing properties minimize leakage and seepage risks.

4. Below-Ground Construction

Basements, lift pits, foundations, and underground rooms benefit significantly from its protective capabilities against soil moisture and hydrostatic pressure.

5. Bathrooms, Kitchens & Roof Slabs

These areas are prone to constant water exposure. Conplast WL XTRA prevents dampness, leakage, and moisture migration through floors and walls.
