Use of Hydraulic Cement for Repairs in Concrete Slabs, Foundations, or Masonry Block/Brick Walls. When should we not seal a foundation wall or floor slab crack? Warning: some crack sealing operations may make crack diagnosis or monitoring more difficult. Watch out: First of all do not just seal a crack if the crack size, shape, pattern, location, or other evidence indicate that. Further evaluation and choice of proper repair method may be in order. If for example we think that there may be active foundation movement or settlement. This photograph of foundation cracks attributed to concrete that included iron sulfide (pyrrhotite), provided courtesy of CCACB - Connecticut Coalition Against Crumbling Basements. The pattern looks like shrinkage but the crack width is larger than normal shrinkage cracking. Concete Crack Sealant hides ongoing movement: Using a flexible sealant in a structural crack may make it difficult to see small amounts of future movement since the sealant. This can increase the difficulty of crack monitoring and diagnosis. Sealant doesn't fix a structural problem: Using a sealant in a foundation or floor slab crack may fail to address the underlying cause of the problem such as foundation. But some epoxy sealants are in fact also a repair: Some structural epoxies may seal and also "repair" the damage in a structural sense. For example Sika produces epoxy resin & structural engineering systems for concrete crack repair using a structural injection system. We may decide to seal a cracked wall or floor slab anyway, to try to reduce water entry in a building, but remember the implications. Types of Sealant Repairs in Concrete & Concrete Structures. Control joint sealant: control joints, designed to control where cracks appear in concrete placed horizontally or vertically, are themselves are sealed against water, frost, debris and to handle recurrent movement (listed below) using a flexible sealant. Recurrent movement: Seal and repair cracks in concrete using injection of either epoxy resin or polyurethane where recurrent movement is expected (in my opinion a flexible sealant is what's called for here) when the movement is considered normal, perhaps caused by traffic vibration or temperature swings, and where the movement is not threatening structural damage. Stop a water leak: Seal and repair cracks in concrete when it is important to quickly stop water leaking through a crack,seal those cracks in concrete using injection of either epoxy resin or polyurethane sealant. Structural repair: Seal and repair structural cracks: for some situations (usually where an engineer, expert in masonry repair has made an assessment), actual structural repairs are made using injectable epoxy resin and possibly in some (probably low- load) cases by using injectable polyurethane sealant. In my opinion (I'm not a P. E.) this application of injected epoxy resin is probably most- appropriate when cracks have appeared due to non- recurrent stresses. When we epoxy cracked structural concrete or a concrete slab that was broken by an initial installation error or by a subsequent event, we expect the repaired area to be as strong or stronger than if no crack were present. Structural reinforcement: some sealant manufacturers such as Sika provide seal or wrap- and- seal systems that actually provide additional strength to existing concrete structures such as concrete columns. Structural reinforcing wrap systems may include use of synethetic fabrics, carbon fibre fabrics, and other wraps. These products might also be used on steel or concrete that has been damaged by weather, frost, corrosion. Surface repair: for working surfaces such as industrial work floors or parking decks cracked by spider- webbed shrinkage cracks that are non- structural, special "healer- sealer" crack sealants may be applied. Specialty Epoxy Resin and Structural Engineering Systems for Concrete. The situations listed above are those of most- interest to owners of residential and smaller commercial buildings. ![]() ![]() Below are examples of additional applications of epoxy resins and sealants in construction: Anchoring epoxy products: used to inject into holes into which connectors such as bolts or post anchors will be placed. Bonding agent epoxies: used to promote secure bonding between abutting, often different materials. A special example is the use of segmental bridge adhesives that bond post- tension pre- cast concrete bridge segments to other structural members or to one another. Epoxy resin adhesives are formulated for bonding concrete to concrete, concrete to other masonry, concrete to steel, and concrete to wood or to other substances. Overlay expoxy resin coatings: used as a coating on concrete surfaces for skid protection or for patching damaged surface areas. Some of these epoxy resin products are formulated for use as a high- friction surface or for use to repair spalled or chipped concrete surfaces.
