Ramco Cements Ltd manufactures a wide range of construction chemical products that meet stringent compliances and are tailored for critical applications delivering reliable performance with unmatched aesthetic finish under the brand name of Hard Worker Engineering Construction Chemical Products
A. Water Proofing :
1. Integral Waterproofing – Hard Worker Integral Waterproofing HW101
Hard Worker Integral Waterproofing is an excellent product for water resistance in concrete. Just up to 200 ml* per 50 kg of cement can reduce water permeability substantially – making the concrete denser and protected from the inside. By becoming part of the structure, HW101 strengthens concrete from within. It does all the above without changing the concreting process. Recommended for Foundations, Columns, Beams and Roof Slabs. HW101 has a
unique property that strengthens the concrete by 10%. *only 75ml – 100ml is required for Ramco Supercrete.
Applications : Waterproofing for Concrete and For durable and dense concrete
Packaging : 1, 5, 10,20,50 & 200L
2. Waterproofing Coat – Hard Worker Waterproofing Coat HW103
Zero seepage. Zero cracks. Any construction is subject to climatic changes and is prone to the stress from expansion and contraction. Hard Worker Waterproofing Coat is a dual component formulation that is flexible under stress. It grips through temperature shifts, and forms a durable, watertight membrane that stays on. Applied on the side from which water enters, the product stops ingress at the source, whether it is roofs, wet areas, walls, water tanks or basements. With just a thin layer that has high spread, it saves cost while delivering waterproofing that ensures structural integrity for years.
Applications:
- Ideal for Water Storage, Water tanks, Sunken areas, Wastewater tanks.
- Exposed Areas – Terraces, Balconies, Sunshades.
- Structural Protection – Basements, Retaining walls, Lift pits, Sumps.
- Decorative Water Features – Swimming pools, Fountains, Water bodies, Canals.
- Utility Areas – Toilets, Sunk slabs.
Packaging : 15Kg Pack
B. Repair Products :
1. Bonding Agent Epoxy – Hard Worker Bonding Agent Epoxy HW403
Hard Worker Bonding Agent Epoxy is designed to anchor new concrete to old, with a grip that’s meant to stay. Whether it’s overhead patchwork or structural overlays, it holds firm, making sure there’s one no-fail, no-slip solid unit that stays bonded through stress and time. The two-part resin–hardener system creates a dense, cross-linked bond that fuses the old and new concrete into a single structural body.
Applications – Concrete Repair, Bonding new concrete to old concrete, Masonry Repair and Precast Joints
Packaging :4L Kit
2. Bonding Agent SBR – Hard Worker Bonding Agent SBR HW404
When a new layer holds tight, the whole repair lasts longer. Hard Worker Bonding Agent SBR is a liquid polymer additive used to create a strong bonding coat between old surfaces and new layers of mortar, screed or plaster. Whether it’s patch repair or floor topping, this bonding layer grips strong — and stays. Mixed in a 1:1 ratio with cement, the SBR forms a tight bond. Once applied, it locks in the new surface without risk of delamination.
Applications :
- Beam and Column Joints: Ideal for bonding old and new concrete.
- Micro Concrete Applications: Enhances the bonding between old surface and micro concrete.
- Repair Mortar Applications: Improves bonding and performance in repair mortars
Packaging : 1, 5, 10L Packs
3. Anchoring Grout – Hard Worker Anchoring Grout HW402
Between the bolt and the base, there’s no room for doubt. Hard Worker Anchoring Grout fills that space with certainty. Whether it’s bolts, plates, turbines or tracks; this non-shrink grout flows deep into gaps and holds firm. Resists oil and water ingress. It fills tight spaces without vibration, grips around the anchor and concrete, and hardens into a monolithic unit that doesn’t shift under both dead and live load. Just a compact, confident fix that stands through stress and time.
Applications
- Heavy machinery & equipment foundation
- Bridge bearing pad grouting & structural columns in pre-cast crane rail construction grouting
- Boiler foundation
- Turbine generator bearing plates
- Windmill foundation grouting.
Packaging : 25Kgs
4. Micro Concrete – Hard Worker Micro Concrete HW401
Where repairs by structural wrapping and jacketing is the only option for concrete, Hard Worker Micro Concrete steps in with certainty. Its high-strength, self-compacting mix flows into tight spaces and holds its shape without vibration or layering. Just add water, mix and pour. It bonds with old concrete, builds strength fast for rapid repairs that don’t just fill thin areas, but restores trust.
Applications
- Repair of damaged reinforced concrete elements, such as beams, columns and walls, where
access is limited and compaction is challenging. - Jacketing of RCC columns to enhance load capacity.
- Rapid repair projects.
- Overlay for existing surfaces in rehabilitation projects to enhance durability and aesthetics.
Available variants are 40 MPa, 60 MPa and 80 MPa.
