WebThe idea is to put the metal rods (rebars) under tension then allow the concrete to set around them. Once the concrete has set you release the tension on the rebars and the rebars then exert a compression force on the concrete. This allows the concrete to deal better with stretching forces. WebChemical Fixings. (95 products) Chemical fixings create a secure, watertight bond. The chemical anchor is injected into the hole where it fills all irregularities to create an airtight seal with virtually no limit on depth. The molecular structure means an even distribution of stress too, so there's less risk of subsequent damage.
