There are traditional external structural strengthening traditional approaches involving additional steel reinforcement, which is either fixed or bonded into holes drilled in the concrete using special cartridge applied epoxy resin bonding agents such as the Sika Anchorfix range , or otherwise mechanically fixed and possibly bonded to the concrete surface i. Use Sikadur-52 may be used to inject and fill cracks between 0. 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. It is available in three grades: rapid, normal and long pot life for low, medium and high ambient temperatures respectively. It not only forms an effective barrier against water infiltration and corrosion promoting media, but it also structurally bonds the concrete sections together. 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. This is to prevent the risk of ancillary structural damage that can be caused by less controllable high pressure resin injection systems, similarly to prevent contamination outside of the structure with resins or other materials during the process.

There are also other fabrics that can be used for certain special strengthening application including Aramid and Glass Fibre Fabrics. Repair floor tile joint for leakage treatment at wet room. Additionally they can be used as a barrier when even after the washing, cleaning and preparation works; there are still potentially residual contaminants, such as chlorides, in the adjacent existing concrete. Therefore these concrete repair materials are also modified with polymers and super-plasticizers that improve their flow and ensure a good surface finish against the formwork.

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. 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. 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. It can also have a significant cost, so if this aspect is carried out unnecessarily or incorrectly, it can add considerable additional cost. This concrete surface protection can also be specified to be: water-repelling through impregnation and pore blocking; elastic and crack-bridging to different degrees of elasticity at different temperatures ; resistant to different chemicals such as in containment zones ; or abrasion and wear resistant e.

Sika product does not shrink during or post-curing process and shows high load capacity. In response to requests from our customers we have also now added an where the most commonly required Concrete Repair and Concrete Facade Protection Products can be selected and ordered if you know what you require. Sikadur-52 does not shrink on curing and forms a rigid, high strength product which exhibits excellent adhesion to most construction materials enabling the restoration of structural adequacy to columns, beams, foundations, decks and water retaining structures. 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. The inclusion of steel reinforcement improves the tensile strength of the element and, consequently, its resistance to stress. 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. 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 material is also ideally suited for bonding of external reinforcement and as a general structural adhesive. Sika Concrete Crack Repair is thixotropic paste than can be applied using regular sealant gun. On horizontal decks for combined chemical and wear resistance, the best protective deck coating products are usually 2 component epoxy and polyurethane resin based solutions that are specifically designed to accommodate this additional stress and exposure. Special higher strength grades of the material are available for segmental bridge and other construction. However if you know the flowable concrete repair mortar or grout product that you require you can buy Pourable Concrete Repair Mortars and Grouts here in our. 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. 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.

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. The choice of specification and levelling mortar selection is therefore dependant on the most important reasons and the requirement for their use on your specific repair project. Machine Applied Concrete Repair Mortars are primarily designed for use where large volumes of the repair mortars are needed, or where a significant volume has to be applied as fast as possible to minimise downtime or closures. This means that their aggregate grading and granulometry, their Water : Cement ratio and in particular, their flow properties, must all be as specified and consistently so. Structural Strengthening always has a very detailed structural engineering input requirement and responsibilities.
