High quality Concrete Repair Mortars products

Concrete repair mortars can be required for a number of reasons, whether that is due to natural structural defects caused by concrete shrinkage or building settlement, due to poor installation of the concrete elements, or due to damage caused by water ingress or corrosion of the internal steel reinforcement. In all such instances, repairs will be required using specialist repair mortar products, however the type of repair mortar needed will differ depending on the scenario.

We stock a range of reinforced and multi-purposes concrete repair mortars as well as bonding agents, primers and anti-corrosion coatings in order to ensure that you can protect your in-situ steel reinforcement and repair your concrete, returning the structure to its original intended condition.

Types of Concrete Repair Mortar

Cementitious, or cement-based concrete repair mortars are widely available and widely used as a quick and easy repair material for either carrying out touch-ups or full repair work. As it is cement-based, the mortar can still be subject to the same issues and weaknesses as the concrete itself, unless a modified cementitous repair mortar is used, which utilise additives to enhance the properties of the concrete repair product. This can include fibre-reinforced repair mortars, high-build options and anti-corrosion additives for protecting against moisture absorption and preventing rust to steel reinforcement.

Epoxy concrete repair mortars are high-strength, non-shrink products that are specially formulated to assist in the repair and reinstatement of concrete flooring. Epoxy repair mortars can also be layered to repair larger gaps and cracks, and thanks to their fast-curing and durable properties they are a versatile option for many concrete repair scenarios.

Protecting Concrete

Once the concrete has been successfully repaired, it is important to consider how you can protect the concrete against future issues by utilising additional protective coatings or membranes. Depending on the product/s used, these can provide corrosion-resistance, water-repellence, and vapour-permeable protective finishes, amongst other options.

Frequently Asked Questions About Concrete Repair Mortars

What is a concrete repair mortar, and what is its purpose?

A concrete repair mortar is a specialised material used for repairing damaged or deteriorated concrete surfaces. It’s designed to restore structural integrity, enhance durability, and improve aesthetic appearance by filling cracks, voids, spalls, and other defects in concrete.

How does concrete repair mortar differ from regular concrete?

Concrete repair mortars typically contain additives or admixtures that improve bonding, reduce shrinkage, enhance workability, and provide corrosion protection. They are formulated to adhere to existing concrete surfaces and withstand harsh environmental conditions, making them suitable for repair and rehabilitation applications.

What types of concrete repair mortars are available?

Concrete repair mortars come in various formulations, including polymer-modified, cementitious, epoxy-based, fibre-reinforced, rapid-setting, and shrinkage-compensating mortars. The choice of mortar depends on factors such as the extent of damage, environmental exposure, structural requirements, and application conditions.

How do I prepare the surface for application of concrete repair mortar?

Surface preparation is crucial for ensuring proper adhesion and performance of concrete repair mortar. It typically involves cleaning, removing loose debris, roughening the substrate, and applying a bonding agent or primer to promote adhesion. Proper surface preparation helps maximise bond strength and durability of the repair.

How long does concrete repair mortar take to cure?

The curing time for concrete repair mortar varies depending on factors such as ambient temperature, humidity, substrate conditions, and product formulation. In general, most repair mortars reach initial set within a few hours and achieve full strength within 28 days, although rapid-setting options are available for quick turnaround projects.

Can concrete repair mortars be used for vertical or overhead repairs?

Yes, many concrete repair mortars are suitable for vertical, overhead, or horizontal applications, depending on their formulation and viscosity. Specialised products are available for overhead repairs or situations where flowability and sag resistance are critical.
