Our Products

Construction chemicals are products used to improve the strength, durability, workability, and protection of building materials. They help reduce water penetration, improve bonding between surfaces, seal joints, and protect structures against environmental damage.

Concrete admixtures such as plasticizers and superplasticizers can improve workability and help reduce the water required in a concrete mix. When used with a properly designed mix, a lower water-to-cement ratio can contribute to higher concrete strength and durability.

Common waterproofing products in Pakistan include bitumen membranes, liquid-applied acrylic coatings, cementitious waterproofing compounds, crystalline systems, and damp-proofing chemicals. Each option serves different purposes, such as protecting roofs, bathrooms, basements, water tanks, and foundations.

Bonding agents are used to improve adhesion between building materials, such as new concrete and existing concrete or plaster. Common options include SBR-based products, PVA-based products for suitable applications, and epoxy bonding agents for specific structural or repair work.

Construction chemical prices vary according to the product type, brand, formulation, pack size, and intended use. On GharHub, the listed Sika and Ultra products were priced at around Rs. 250–7,000 per pack or product, depending on the item. Contact GharHub for current rates, available brands, pack sizes, and delivery charges.

The cost of anti-termite treatment depends on the product formulation, concentration, pack size, treatment method, and area requiring protection. GharHub lists approximately Rs. 4,000–6,000 per litre, but confirm this range against current product listings or a quotation.

The brands and products listed in your supplied content include Sika and Ultra construction chemicals, along with anti-termite treatment products. Availability may differ by category, formulation, pack size, and current stock. Contact GharHub to confirm current availability and request a quotation for your project.

A curing compound is a liquid applied to freshly placed concrete to form a film that reduces moisture loss during early curing. Maintaining adequate moisture helps concrete develop its intended strength and durability while reducing the risk of surface defects associated with rapid drying.

Construction sealants are used to close joints, gaps, and selected cracks to reduce the passage of water, air, dust, or other unwanted materials. Choose a product compatible with the surface, expected joint movement, weather exposure, and moisture conditions.

A technical data sheet is a document that explains a construction chemical's intended use, application method, coverage, mixing instructions, and performance characteristics. It may also provide information about surface preparation, drying or curing time, storage, temperature limits, and compatibility with other materials.

The best roof waterproofing chemical depends on the roof surface, water exposure, weather conditions, and whether the roof is accessible or exposed to sunlight. Liquid-applied acrylic or polyurethane systems and bitumen membranes are among the available options.

Waterproofing is intended to resist water penetration under the exposure conditions for which a system is designed, potentially including hydrostatic pressure. Damp-proofing primarily limits moisture movement through surfaces and is generally used where significant water pressure is not expected.

he suitable crack-repair product depends on the crack's width, depth, movement, location, and underlying cause. Epoxy injection may be appropriate for certain stable structural cracks, while flexible polyurethane products can be used for some cracks where water ingress is a concern.

Some construction chemicals require a dry surface, while others are designed for damp or saturated surfaces. For example, certain cementitious waterproofing products can be applied to pre-dampened substrates, whereas some epoxy coatings and bonding products require specific moisture conditions.

Construction chemicals can be used safely when handled according to the product label, safety data sheet, and manufacturer's instructions. Depending on the formulation, precautions may include wearing gloves and eye protection, ensuring adequate ventilation, and avoiding skin contact or inhalation of vapours.

Store construction chemicals in their original, sealed containers in the temperature and humidity conditions specified by the manufacturer. Protect them from direct sunlight, rain, excessive heat, freezing, and contamination, as applicable to the product.

Sometimes Yes, but the existing waterproofing system must first be assessed for adhesion, damage, compatibility, and moisture conditions. Loose coatings, blistering, contamination, and failed joints may need removal or repair before a new system is applied.

Confirm the exact product name, formulation, pack size, quantity, shelf life, and suitability for the intended application. Request a written quotation that specifies the unit price, total quantity, delivery charges, and any applicable discounts.

Anti-termite treatment uses approved products and application methods to protect buildings against termite activity. Depending on the product and construction stage, treatment may be required if your building is infested with any insects.
