How to choose bagged concrete mortar and grout

Choose bagged concrete for suitable concrete pours and repairs, mortar for its specified masonry or bedding application, and grout for the particular joints or voids it is designed to fill. These materials are not interchangeable. Start with the job, then check strength, application depth, working time and mixing requirements.

Concrete mortar and grout have different jobs

Bagged concrete contains a pre-blended mix for concreting work. Masonry mortar is formulated for tasks such as laying bricks and blocks or pointing compatible masonry. Specialist bedding mortars support particular components or paving systems. Grout can mean a paving jointing product or a technical construction grout, each with a different specification.

A product described as high strength is not automatically the right choice for every job. The material must suit the substrate, exposure, application thickness and performance specified for the work. Existing or historic masonry, for example, needs an assessment of mortar compatibility rather than simply choosing the strongest available mix.

High Performance Grout

Specified construction void filling and grouting applications

Choose concrete for bases paths and repairs

General Purpose Concrete is listed for paths, steps, shed bases and general repairs. High Performance Concrete provides another option where its declared performance meets the project requirements. For foundations or structural work, confirm the complete specification before choosing either product.

Rapid Set Backfill Concrete addresses different work, including access cover and gully reinstatement and thick-section repairs. Its short application window means preparation and placement need to be organised before mixing. Do not assume the same handling time as a general purpose concrete.

Choose mortar for masonry or specialist bedding

General Purpose Mortar is the starting point for suitable brick and block laying, pointing and patching. Check its compatibility with the masonry and project requirements, particularly for repairs to existing work.

High Strength Bedding Mortar is intended for specified precast concrete bedding and gap packing. Rapid Set Bedding Mortar serves applications such as access cover frames and highway ironwork where early strength is required. Neither should be treated as a general substitute for masonry mortar.

Paving bedding mortar and paving grout are different layers

Paving Bedding Mortar forms the bed beneath suitable stone, clay, concrete or porcelain paving. Paving Grout fills joints between compatible paving units. Selecting one does not remove the need for the other layers required by the paving design.

Check the paving type, base, bedding depth, joint dimensions, drainage and intended traffic as a complete system. Follow the paving bedding instructions for priming and bonding. Do not use a paving jointing grout as a replacement for the bedding layer or assume a bound system suits every paving installation.

Construction grout is a separate product choice

High Performance Grout is a cementitious construction grout for its specified void filling and grouting applications. Its water allowance depends on the required preparation, such as dry packing, trowelling or high-flow use. This is a different selection from paving joint grout.

For structural or precision work, use the specified product and application method. Adding water outside the stated limits to make a grout flow more easily can compromise the intended result.

Check mixing compatibility separately

Selecting a suitable bagged material does not automatically establish compatibility with a particular mixer. Check the product’s prescribed equipment, mixing duration and water allowance. Where continuous mixing is proposed, obtain confirmation for the exact material and application rather than assuming every concrete, mortar or grout can be mixed that way.
