However it is obvious that if not treated and sealed appropriately with the right joint sealing materials, then any of the joints in a structure can be the source of future problems with further deterioration and water damage likely, together with additional cost. Sika Concrete Crack Repair will be a perfect choice for repairs of corners and edges, hole and void filling, crack filling and sealing of non-moving joints as well as joint arrises. The electrochemically active layer on the steel surface prevents the formation of both anodic and cathodic areas, which as a result, significantly extends the time to the onset of corrosion, and it also significantly reduces the rate of any corrosion that is eventually able to take place. They are ideal for patch repairs and repairs to concrete spalling in areas of locally corroding reinforcement, etc. This is why these corrosion inhibitors can form such a valuable part of an overall concrete repair and protection system; because they can effectively extend the service life of reinforced concrete structures. There are special tests that have been developed to monitor and confirm all of these aspects on your project, we can also advise and assist you with these tests, both pre-contract and on site. Resin Injection to Repair Non—Structural Cracks in Concrete.
Traditional Gunite systems for sprayed concrete repairs are not normally pre-batched but produced on site - therefore they are now generally only used for applications requiring thicker layers of repair, where their constituent materials grading and granulometry is not as critical as it is for layers of sprayed concrete below 50mm thickness for example. Resin Bonding of Dowel Bar Low Pressure Resin Injection Internal Crack Injection of a Concrete Silo Resin Crack Injection by Cartridge Gun Cracks in concrete buildings and other structures must always be inspected by the responsible Structural Engineer before the concrete repair and protection works begin. Structural Strengthening always has a very detailed structural engineering input requirement and responsibilities. There are special resin injection materials that are suitable and approved for use in contact with potable drinking water, plus materials that can accommodate, oe even displace any water in the cracks within the structure. The correct resin injection process can fully restore structural integrity to cracked areas or sections of reinforced concrete and ensure long term durability, with an extended service life of the structure.
Structural Strengthening to Repair Reinforced Concrete. Structural strengthening works should only be carried out by trained and experienced contractors after qualified structural investigation and analysis, therefore we do not include structural strengthening products in our Online Shop. Packaging 3 kg net pre-proportioned kits. In order to meet all of the different requirements for concrete facades and horizontal concrete surfaces on different structures and in different exposure conditions, there are a wide range of different protective concrete coating products and systems required. The strengthening works can usually be included within the remit and programme of the overall concrete repair and protection works, so for specific advice on your project, please call any of our offices and our experts will be happy to assist you.

Applying Protective Surface Coating by Hand Applying Protective Surface Coating by Airless Spray Applying Heavy Duty Protective Coating in a Chemical Containment Tank Protective Surface Coatings Work Completed Protective surface coatings are primarily used to protect new or repaired concrete surfaces from future chemical attack e. Due to their small molecular size and penetrating ability, together with their unique water-repelling or hydrophobic properties, they can penetrate completely into the surface pores and capillaries of concrete and other facade surfaces; thereby creating a water repellent hydrophobic surface, but without any significant residual surface film and therefore this is also achieved without changing the surface appearance as would a protective paint coating or cement based material. Alternatively if the crack has led to, or been caused by other significant or larger voids such as areas of honeycombing or inadequate compaction around reinforcement or other details or penetrations through the concrete, then these should be filled with an appropriate cement or resin based grout. The steel reinforcement primer is applied to any exposed steel reinforcement that has been cleaned and prepared, preferably by mechanical blast-cleaning, once the damaged concrete and any contaminants such as chlorides have been removed.
Please call any of our offices for expert assistance. Like hydrophobic impregnations, the performance of corrosion inhibitors is dependent on their correct application and the penetration of the correct quantity of the product to the level of the steel reinforcement. Surface Levelling Mortars are also used to restore the original line, level, profile and texture to the concrete surface, plus they also provides an ideal substrate when an additional protective coating needs to be applied i. Unfortunately, in the presence of water and oxygen, steel corrodes. .
Please contact any of our offices for advice and assistance with the right flow applied concrete repair or grouting product selection for your specific project. Structural Strengthening may also involve the filling or injection of cracks with suitable structural epoxy resins — we cover the Resin Injection of Cracks structural and non-structural cracks in the next Specialist Concrete repair Products and Systems section below. Resin Injection of Structural Cracks in Concrete. When a crack has structural significance then provided that the responsible Structural Engineer is satisfied that the source of the damage i. Please call any of our offices for advice and guidance on any aspect of these concrete repair materials, their selection and specification, detailing or their application and quality control on-site.
Therefore for specific advice on your joint sealing requirements please contact any of our offices and one of our specialists will be pleased to assist you. With all types of hydrophobic impregnation the amount of material that is applied and the depth to which it is able to penetrate into the concrete surface, are critical factors in the effectiveness of the treatment, the resulting water-repelling performance and most significantly, the durability of the water-repellancy. This means that the specification and required thickness of the surface levelling mortar can be a critical part of a technically correct concrete repair and protection solution. Stimsonite 980 Road Studs are surface mounted road studs that are injection moulded from durable polymers to endure high traffic volumes. Most sprayed repair mortar applications require specialist equipment, training and experience, therefore we do not include many concrete repair mortar products that are designed to be exclusively spray applied in our , although with the right knowledge and equipment it is possible to wet or dry spray almost any mortar products these days — Please call any of our office for specific advice on any aspect of sprayed concrete repairs.
