BBA HAPAS Certification – Concrete Rehabilitation

Once the old layers of asphalt have been removed and the texture to the concrete surface restored, the surface needs protecting from water ingress and what better products to use than BBA HAPAS approved systems.

Certified products ensure that the systems installed are the best fit for purpose and will perform as expected.


All ironwork in reset using the Ironmaster BBA HAPAS approved ironwork repair system.

Crack and Joint Repairs and Kerb Sealing

We are utilising a concrete coloured material for this purpose which has flexible HAPAS approval as a crack repair system. Message us for more details.

Patch Repairs

Asphalt patches and bay replacements (with asphalt) can be treated with a concrete coloured Masterscreed material to give an overall concrete coloured effect across the whole surface. Masterscreed is a BBA HAPAS approved material.


Why specify BBA HAPAS materials for your concrete road repairs?

With BBA HAPAS materials you can rest assured that independent testing and product approvals have taken place giving confidence in the material performance and fit for purpose.

With concrete joint repairs a BBA HAPAS material can be assured of the following:

Flexible: A flexible material that will absorb the thermal movement associated with concrete joints whilst remaining adhered to the concrete, bridging the joint, absorbing traffic movements and maintaining a skid resistant surface.

Adhesion: The material will stay adhered to the concrete throughout the movement cycles.

Long lasting: Tested and approved for minimum life of 5 years and a mass of evidence of a much longer lifespan.

Withstands Traffic: BBA HAPAS requirements include accelerated wear test under a wheel track testing device at 50 deg.c. This means that the material will withstand wheel track rutting in hot temperatures.

Skid resistant finish: BBA HAPAS testing requirements are for initial texture depth and skid resistance values and then these measures are tested again following accelerated wear tests, which means you can be assured of a safe surface finish on the highway.

Specifying BBA HAPAS approved materials gives you assurances that all of these factors have been taken into consideration and the right product has been chosen for the job.


Deterioration of concrete roads

Concrete joints in roads can deteriorate due to a combination of factors, primarily related to environmental conditions, traffic loads, and the inherent properties of concrete.

Here at Rhino we can help with the maintenance aspects of joint deterioration and water ingress into the substructure of the highway.

Inadequate maintenance of concrete joints including timely sealing and repair of joints, cracks and openings in the joints can allow water and contaminants to infiltrate, accelerating the deterioration. A typical example would be where deterioration of the joint sealant allows detritus and specifically aggregates to sit in the joint cavity. During the expansion and contraction process brought about by the change in temperatures the joint arris will break when expanding against a piece of aggregate caught in the joint. Once these arises have been damaged then traditional joint sealing will no longer be effective and a BBA HAPAS material recessed into a rebated joint is the only long term solution.

A typical rebated joint might be 200mm wide by 40mm deep, located central over the crack or joint. A flexible grade, BBA HAPAS approved crack repair system, rebated into the surface will have 30% flexibility and accommodate further substrate movement created by the freeze-thaw cycle. With an applied aggregate dressing for skid resistance, this will provide a long term joint solution to damaged joints and cracks which will keep water out of the substructure.

When couple with the same material to seal along the kerb edge, the concrete road can be protected from the ingress of water.

Why is water ingress a problem?

1.    Freeze-Thaw Cycles: In regions with varying temperatures, the expansion and contraction caused by freeze-thaw cycles can put stress on concrete joints. When water enters the joints and freezes, it expands, potentially causing cracks and deterioration.

2.    Chemical Exposure: Roads are exposed to a variety of chemicals, such as de-icing salts, oil, and other contaminants. These chemicals can penetrate the concrete and weaken its structure, making it more susceptible to deterioration.

3.    Moisture Intrusion: Moisture can penetrate into the joints and cause the steel reinforcement inside the concrete to corrode. This corrosion can weaken the surrounding concrete and lead to cracking and joint degradation.
